Title: Devices, methods, and graphical user interfaces for interacting with a control object while dragging another object

Abstract:
An electronic device with a display, a touch-sensitive surface, and one or more sensors that detect intensities of contacts on the touch-sensitive surface displays, on the display, a user interface. While displaying the user interface, the electronic device detects an input that includes a contact on the touch-sensitive surface. In response to detecting the input while displaying the user interface, and while continuing to detect the input on the touch-sensitive surface: If an intensity of the contact satisfies an activation intensity threshold, the electronic device performs a first operation associated with the activation intensity threshold. The activation intensity threshold is determined based on whether or not prior inputs by the user on the touch-sensitive surface exceed a respective intensity threshold. If an intensity of the contact does not satisfy an activation intensity threshold, the electronic device forgoes performing the first operation associated with the activation intensity threshold.

     TECHNICAL FIELD 
     This relates generally to electronic devices with touch-sensitive surfaces, including but not limited to electronic devices with touch-sensitive surfaces that perform various display operations in conjunction with receiving and/or generating tactile information. 
     BACKGROUND 
     The use of touch-sensitive surfaces as input devices for computers and other electronic computing devices has increased significantly in recent years. Exemplary touch-sensitive surfaces include touchpads and touch-screen displays. Such surfaces are widely used to perform display operations on a user interface of a display. 
     Exemplary display operations include adjusting the position of one or more user interface objects, activating buttons or opening files/applications represented by user interface objects, as well as changing the view of one or more portions of a user interface. Exemplary user interface objects include files, folders, calendar entries, icons, and control elements such as buttons and other graphics. A user will, in some circumstances, need to perform display operations involving user interface objects in a file management program (e.g., Finder from Apple Inc. of Cupertino, California), a calendaring program (e.g., iCal from Apple Inc. of Cupertino, California), an image management application (e.g., Aperture, iPhoto, or Photos from Apple Inc. of Cupertino, California), a digital content (e.g., videos and music) management application (e.g., iTunes from Apple Inc. of Cupertino, California), a drawing application, a presentation application (e.g., Keynote from Apple Inc. of Cupertino, California), a word processing application (e.g., Pages from Apple Inc. of Cupertino, California), or a spreadsheet application (e.g., Numbers from Apple Inc. of Cupertino, California). 
     But existing methods for performing these display operations are cumbersome and inefficient, and can take multiple steps. For example, if a user wishes to change a view while dragging one or more user interface objects, the user needs to release the one or more user interface objects and change a view of a portion of a user interface, and then pick up the one or more user interface objects again to move the one or more user interface objects to the changed view. This sequence of steps is complex and takes additional time. 
     SUMMARY 
     Accordingly, there is a need for electronic devices with faster, more efficient methods and interfaces for performing various display operations. Such methods and interfaces optionally complement or replace conventional methods for performing various display operations. In addition, when tactile outputs are used to provide feedback to users, there is a need for methods and interfaces for adjusting tactile outputs. Such methods and interfaces optionally complement or replace conventional methods for providing tactile outputs. Such methods and interfaces reduce the number, extent, and/or nature of the inputs from a user and produce a more efficient human-machine interface. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges.

     DESCRIPTION OF EMBODIMENTS 
     Many electronic devices have graphical user interfaces with draggable user interface objects (e.g., files, folders, calendar entries, and icons) and control user interface objects (e.g., buttons, switches, sliders, and other controls). When a user selects a calendar entry for today in a month view and moves it to a different date and time, the user may need to drag the calendar entry to the different date and drop the calendar entry, switch to a day view, and then drag the calendar entry again and drop it on a new time. Alternatively, the user may open the calendar entry and manually type in the new date and time. In the embodiments described below, an improved method for performing operations (e.g., moving a calendar entry) is achieved by displaying a user interface that includes a draggable object (e.g., a calendar entry) and control objects (e.g., view buttons). While the draggable object is being dragged, one of the control objects is activated to change the view (e.g., from the month view to the day view), and the draggable object is dropped into a user-specified location (e.g., a user-specified time slot). This method allows for interaction with control objects while dragging a draggable object, thereby eliminating the need for extra, separate steps for interacting with control objects. This method, which uses a single contact to both drag an object and interact with a control object, is optionally be used in other applications as well. 
     Below,  FIGS.  1 A- 1 B,  2 , and  3    provide a description of exemplary devices.  FIGS.  4 A- 4 B, and  5 A- 5 NN , illustrate exemplary user interfaces for processing touch inputs.

The user interfaces in  FIGS.  5 A- 5 NN  and the intensity diagrams in  FIGS.  5 OO- 5 QQ  are used to illustrate the processes in  FIGS.  6 A- 6 E,  7 A- 7 D,  8 A- 8 F, and  9 A- 9 C . 
     Exemplary Devices 
     Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the various described embodiments. However, it will be apparent to one of ordinary skill in the art that the various described embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments. 
     It will also be understood that, although the terms first, second, etc. are, in some instances, used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the scope of the various described embodiments. The first contact and the second contact are both contacts, but they are not the same contact, unless the context clearly indicates otherwise. 
     The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     As used herein, the term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context. 
     Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, California Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch-screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch-screen display and/or a touchpad). 
     In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse and/or a joystick. 
     The device typically supports a variety of applications, such as one or more of the following: a note taking application, a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application. 
     The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user. 
     Attention is now directed toward embodiments of portable devices with touch-sensitive displays.  FIG.  1 A  is a block diagram illustrating portable multifunction device  100  with touch-sensitive display system  112  in accordance with some embodiments. Touch-sensitive display system  112  is sometimes called a “touch screen” for convenience, and is sometimes simply called a touch-sensitive display. Device  100  includes memory  102  (which optionally includes one or more computer readable storage mediums), memory controller  122 , one or more processing units (CPUs)  120 , peripherals interface  118 , RF circuitry  108 , audio circuitry  110 , speaker  111 , microphone  113 , input/output (I/O) subsystem  106 , other input or control devices  116 , and external port  124 . Device  100  optionally includes one or more optical sensors  164 . Device  100  optionally includes one or more intensity sensors  165  for detecting intensity of contacts on device  100  (e.g., a touch-sensitive surface such as touch-sensitive display system  112  of device  100 ). Device  100  optionally includes one or more tactile output generators  167  for generating tactile outputs on device  100  (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system  112  of device  100  or touchpad  355  of device  300 ). These components optionally communicate over one or more communication buses or signal lines  103 . 
     As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user&#39;s sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user&#39;s hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user&#39;s movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user. 
     It should be appreciated that device  100  is only one example of a portable multifunction device, and that device  100  optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in  FIG.  1 A  are implemented in hardware, software, firmware, or a combination thereof, including one or more signal processing and/or application specific integrated circuits. 
     Memory  102  optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory  102  by other components of device  100 , such as CPU(s)  120  and the peripherals interface  118 , is, optionally, controlled by memory controller  122 . 
     Peripherals interface  118  can be used to couple input and output peripherals of the device to CPU(s)  120  and memory  102 . The one or more processors  120  run or execute various software programs and/or sets of instructions stored in memory  102  to perform various functions for device  100  and to process data. 
     In some embodiments, peripherals interface  118 , CPU(s)  120 , and memory controller  122  are, optionally, implemented on a single chip, such as chip  104 . In some other embodiments, they are, optionally, implemented on separate chips. 
     RF (radio frequency) circuitry  108  receives and sends RF signals, also called electromagnetic signals. RF circuitry  108  converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals.

The wireless communication optionally uses any of a plurality of communications standards, protocols and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSDPA), Evolution, Data-Only (EV-DO), HSPA, HSPA+, Dual-Cell HSPA (DC-HSPDA), long term evolution (LTE), near field communication (NFC), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11ac, IEEE 802.11ax, IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e-mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document. 
     Audio circuitry  110 , speaker  111 , and microphone  113  provide an audio interface between a user and device  100 . Audio circuitry  110  receives audio data from peripherals interface  118 , converts the audio data to an electrical signal, and transmits the electrical signal to speaker  111 . Speaker  111  converts the electrical signal to human-audible sound waves. Audio circuitry  110  also receives electrical signals converted by microphone  113  from sound waves. Audio circuitry  110  converts the electrical signal to audio data and transmits the audio data to peripherals interface  118  for processing. Audio data is, optionally, retrieved from and/or transmitted to memory  102  and/or RF circuitry  108  by peripherals interface  118 . In some embodiments, audio circuitry  110  also includes a headset jack (e.g.,  212 ,  FIG.  2   ). The headset jack provides an interface between audio circuitry  110  and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone). 
     I/O subsystem  106  couples input/output peripherals on device  100 , such as touch-sensitive display system  112  and other input or control devices  116 , with peripherals interface  118 . I/O subsystem  106  optionally includes display controller  156 , optical sensor controller  158 , intensity sensor controller  159 , haptic feedback controller  161 , and one or more input controllers  160  for other input or control devices. The one or more input controllers  160  receive/send electrical signals from/to other input or control devices  116 . The other input or control devices  116  optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s)  160  are, optionally, coupled with any (or none) of the following: a keyboard, infrared port, USB port, stylus, and/or a pointer device such as a mouse. The one or more buttons (e.g.,  208 ,  FIG.  2   ) optionally include an up/down button for volume control of speaker  111  and/or microphone  113 . The one or more buttons optionally include a push button (e.g.,  206 ,  FIG.  2   ). 
     Touch-sensitive display system  112  provides an input interface and an output interface between the device and a user. Display controller  156  receives and/or sends electrical signals from/to touch-sensitive display system  112 . Touch-sensitive display system  112  displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output corresponds to user-interface objects. As used herein, the term “affordance” refers to a user-interactive graphical user interface object (e.g., a graphical user interface object that is configured to respond to inputs directed toward the graphical user interface object). Examples of user-interactive graphical user interface objects include, without limitation, a button, slider, icon, selectable menu item, switch, hyperlink, or other user interface control. 
     Touch-sensitive display system  112  has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch-sensitive display system  112  and display controller  156  (along with any associated modules and/or sets of instructions in memory  102 ) detect contact (and any movement or breaking of the contact) on touch-sensitive display system  112  and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch-sensitive display system  112 . In an exemplary embodiment, a point of contact between touch-sensitive display system  112  and the user corresponds to a finger of the user or a stylus. 
     Touch-sensitive display system  112  optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch-sensitive display system  112  and display controller  156  optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch-sensitive display system  112 . In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, California. 
     Touch-sensitive display system  112  optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen video resolution is in excess of 400 dpi (e.g., 500 dpi, 800 dpi, or greater). The user optionally makes contact with touch-sensitive display system  112  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     In some embodiments, in addition to the touch screen, device  100  optionally includes a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch-sensitive display system  112  or an extension of the touch-sensitive surface formed by the touch screen. 
     Device  100  also includes power system  162  for powering the various components. Power system  162  optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices. 
     Device  100  optionally also includes one or more optical sensors  164 .  FIG.  1 A  shows an optical sensor coupled with optical sensor controller  158  in I/O subsystem  106 . Optical sensor(s)  164  optionally include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor(s)  164  receive light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module  143  (also called a camera module), optical sensor(s)  164  optionally capture still images and/or video. In some embodiments, an optical sensor is located on the back of device  100 , opposite touch-sensitive display system  112  on the front of the device, so that the touch screen is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user&#39;s image is obtained (e.g., for selfies, for videoconferencing while the user views the other video conference participants on the touch screen, etc.). 
     Device  100  optionally also includes one or more contact intensity sensors  165 .  FIG.  1 A  shows a contact intensity sensor coupled with intensity sensor controller  159  in I/O subsystem  106 . Contact intensity sensor(s)  165  optionally include one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor(s)  165  receive contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ). In some embodiments, at least one contact intensity sensor is located on the back of device  100 , opposite touch-screen display system  112  which is located on the front of device  100 . 
     Device  100  optionally also includes one or more proximity sensors  166 .  FIG.  1 A  shows proximity sensor  166  coupled with peripherals interface  118 . Alternately, proximity sensor  166  is coupled with input controller  160  in I/O subsystem  106 . In some embodiments, the proximity sensor turns off and disables touch-sensitive display system  112  when the multifunction device is placed near the user&#39;s ear (e.g., when the user is making a phone call). 
     Device  100  optionally also includes one or more tactile output generators  167 .  FIG.  1 A  shows a tactile output generator coupled with haptic feedback controller  161  in I/O subsystem  106 . Tactile output generator(s)  167  optionally include one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Tactile output generator(s)  167  receive tactile feedback generation instructions from haptic feedback module  133  and generates tactile outputs on device  100  that are capable of being sensed by a user of device  100 . In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device  100 ) or laterally (e.g., back and forth in the same plane as a surface of device  100 ). In some embodiments, at least one tactile output generator sensor is located on the back of device  100 , opposite touch-sensitive display system  112 , which is located on the front of device  100 . 
     Device  100  optionally also includes one or more accelerometers  168 .  FIG.  1 A  shows accelerometer  168  coupled with peripherals interface  118 .

In some embodiments, information is displayed on the touch-screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device  100  optionally includes, in addition to accelerometer(s)  168 , a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device  100 . 
     In some embodiments, the software components stored in memory  102  include operating system  126 , communication module (or set of instructions)  128 , contact/motion module (or set of instructions)  130 , graphics module (or set of instructions)  132 , haptic feedback module (or set of instructions)  133 , text input module (or set of instructions)  134 , Global Positioning System (GPS) module (or set of instructions)  135 , and applications (or sets of instructions)  136 . Furthermore, in some embodiments, memory  102  stores device/global internal state  157 , as shown in  FIGS.  1 A and  3   . Device/global internal state  157  includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch-sensitive display system  112 ; sensor state, including information obtained from the device&#39;s various sensors and other input or control devices  116 ; and location and/or positional information concerning the device&#39;s location and/or attitude. 
     Operating system  126  (e.g., iOS, Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     Communication module  128  facilitates communication with other devices over one or more external ports  124  and also includes various software components for handling data received by RF circuitry  108  and/or external port  124 . External port  124  (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, California In some embodiments, the external port is a Lightning connector that is the same as, or similar to and/or compatible with the Lightning connector used in some iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, California. 
     Contact/motion module  130  optionally detects contact with touch-sensitive display system  112  (in conjunction with display controller  156 ) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module  130  includes various software components for performing various operations related to detection of contact (e.g., by a finger or by a stylus), such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module  130  receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts or stylus contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module  130  and display controller  156  detect contact on a touchpad. 
     Contact/motion module  130  optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event. Similarly, tap, swipe, drag, and other gestures are optionally detected for a stylus by detecting a particular contact pattern for the stylus.

     Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory  102  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  102  optionally stores additional modules and data structures not described above. 
     In some embodiments, device  100  is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device  100 , the number of physical input control devices (such as push buttons, dials, and the like) on device  100  is, optionally, reduced. 
     The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device  100  to a main, home, or root menu from any user interface that is displayed on device  100 . In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad. 
       FIG.  1 B  is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory  102  (in  FIG.  1 A ) or  370  ( FIG.  3   ) includes event sorter  170  (e.g., in operating system  126 ) and a respective application  136 - 1  (e.g., any of the aforementioned applications  136 ,  137 - 155 ,  380 - 390 ). 
     Event sorter  170  receives event information and determines the application  136 - 1  and application view  191  of application  136 - 1  to which to deliver the event information. Event sorter  170  includes event monitor  171  and event dispatcher module  174 . In some embodiments, application  136 - 1  includes application internal state  192 , which indicates the current application view(s) displayed on touch-sensitive display system  112  when the application is active or executing. In some embodiments, device/global internal state  157  is used by event sorter  170  to determine which application(s) is (are) currently active, and application internal state  192  is used by event sorter  170  to determine application views  191  to which to deliver event information. 
     In some embodiments, application internal state  192  includes additional information, such as one or more of: resume information to be used when application  136 - 1  resumes execution, user interface state information that indicates information being displayed or that is ready for display by application  136 - 1 , a state queue for enabling the user to go back to a prior state or view of application  136 - 1 , and a redo/undo queue of previous actions taken by the user. 
     Event monitor  171  receives event information from peripherals interface  118 . Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display system  112 , as part of a multi-touch gesture). Peripherals interface  118  transmits information it receives from I/O subsystem  106  or a sensor, such as proximity sensor  166 , accelerometer(s)  168 , and/or microphone  113  (through audio circuitry  110 ). Information that peripherals interface  118  receives from I/O subsystem  106  includes information from touch-sensitive display system  112  or a touch-sensitive surface. 
     In some embodiments, event monitor  171  sends requests to the peripherals interface  118  at predetermined intervals. In response, peripherals interface  118  transmits event information. In other embodiments, peripheral interface  118  transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration). 
     In some embodiments, event sorter  170  also includes a hit view determination module  172  and/or an active event recognizer determination module  173 . 
     Hit view determination module  172  provides software procedures for determining where a sub-event has taken place within one or more views, when touch-sensitive display system  112  displays more than one view. Views are made up of controls and other elements that a user can see on the display. 
     Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture. 
     Hit view determination module  172  receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module  172  identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (i.e., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view. 
     Active event recognizer determination module  173  determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module  173  determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module  173  determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views. 
     Event dispatcher module  174  dispatches the event information to an event recognizer (e.g., event recognizer  180 ). In embodiments including active event recognizer determination module  173 , event dispatcher module  174  delivers the event information to an event recognizer determined by active event recognizer determination module  173 . In some embodiments, event dispatcher module  174  stores in an event queue the event information, which is retrieved by a respective event receiver module  182 . 
     In some embodiments, operating system  126  includes event sorter  170 . Alternatively, application  136 - 1  includes event sorter  170 . In yet other embodiments, event sorter  170  is a stand-alone module, or a part of another module stored in memory  102 , such as contact/motion module  130 . 
     In some embodiments, application  136 - 1  includes a plurality of event handlers  190  and one or more application views  191 , each of which includes instructions for handling touch events that occur within a respective view of the application&#39;s user interface. Each application view  191  of the application  136 - 1  includes one or more event recognizers  180 . Typically, a respective application view  191  includes a plurality of event recognizers  180 . In other embodiments, one or more of event recognizers  180  are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application  136 - 1  inherits methods and other properties. In some embodiments, a respective event handler  190  includes one or more of: data updater  176 , object updater  177 , GUI updater  178 , and/or event data  179  received from event sorter  170 . Event handler  190  optionally utilizes or calls data updater  176 , object updater  177  or GUI updater  178  to update the application internal state  192 . Alternatively, one or more of the application views  191  includes one or more respective event handlers  190 . Also, in some embodiments, one or more of data updater  176 , object updater  177 , and GUI updater  178  are included in a respective application view  191 . 
     A respective event recognizer  180  receives event information (e.g., event data  179 ) from event sorter  170 , and identifies an event from the event information. Event recognizer  180  includes event receiver  182  and event comparator  184 . In some embodiments, event recognizer  180  also includes at least a subset of: metadata  183 , and event delivery instructions  188  (which optionally include sub-event delivery instructions). 
     Event receiver  182  receives event information from event sorter  170 . The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device. 
     Event comparator  184  compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator  184  includes event definitions  186 . Event definitions  186  contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 ( 187 - 1 ), event 2 ( 187 - 2 ), and others. In some embodiments, sub-events in an event  187  include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 ( 187 - 1 ) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first lift-off (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second lift-off (touch end) for a predetermined phase. In another example, the definition for event 2 ( 187 - 2 ) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display system  112 , and lift-off of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers  190 . 
     In some embodiments, event definition  187  includes a definition of an event for a respective user-interface object. In some embodiments, event comparator  184  performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display system  112 , when a touch is detected on touch-sensitive display system  112 , event comparator  184  performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler  190 , the event comparator uses the result of the hit test to determine which event handler  190  should be activated. For example, event comparator  184  selects an event handler associated with the sub-event and the object triggering the hit test. 
     In some embodiments, the definition for a respective event  187  also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer&#39;s event type. 
     When a respective event recognizer  180  determines that the series of sub-events do not match any of the events in event definitions  186 , the respective event recognizer  180  enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture. 
     In some embodiments, a respective event recognizer  180  includes metadata  183  with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy. 
     In some embodiments, a respective event recognizer  180  activates event handler  190  associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer  180  delivers event information associated with the event to event handler  190 . Activating an event handler  190  is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer  180  throws a flag associated with the recognized event, and event handler  190  associated with the flag catches the flag and performs a predefined process. 
     In some embodiments, event delivery instructions  188  include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process. 
     In some embodiments, data updater  176  creates and updates data used in application  136 - 1 . For example, data updater  176  updates the telephone number used in contacts module  137 , or stores a video file used in video player module  145 . In some embodiments, object updater  177  creates and updates objects used in application  136 - 1 . For example, object updater  177  creates a new user-interface object or updates the position of a user-interface object. GUI updater  178  updates the GUI. For example, GUI updater  178  prepares display information and sends it to graphics module  132  for display on a touch-sensitive display. 
     In some embodiments, event handler(s)  190  includes or has access to data updater  176 , object updater  177 , and GUI updater  178 . In some embodiments, data updater  176 , object updater  177 , and GUI updater  178  are included in a single module of a respective application  136 - 1  or application view  191 . In other embodiments, they are included in two or more software modules. 
     It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices  100  with input-devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc., on touch-pads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized. 
       FIG.  2    illustrates a portable multifunction device  100  having a touch screen (e.g., touch-sensitive display system  112 ,  FIG.  1 A ) in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI)  200 . In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers  202  (not drawn to scale in the figure) or one or more styluses  203  (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device  100 . In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap. 
     Device  100  optionally also includes one or more physical buttons, such as “home” or menu button  204 . As described previously, menu button  204  is, optionally, used to navigate to any application  136  in a set of applications that are, optionally executed on device  100 . Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on the touch-screen display. 
     In some embodiments, device  100  includes the touch-screen display, menu button  204 , push button  206  for powering the device on/off and locking the device, volume adjustment button(s)  208 , Subscriber Identity Module (SIM) card slot  210 , head set jack  212 , and docking/charging external port  124 . Push button  206  is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In some embodiments, device  100  also accepts verbal input for activation or deactivation of some functions through microphone  113 . Device  100  also, optionally, includes one or more contact intensity sensors  165  for detecting intensity of contacts on touch-sensitive display system  112  and/or one or more tactile output generators  167  for generating tactile outputs for a user of device  100 . 
       FIG.  3    is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device  300  need not be portable. In some embodiments, device  300  is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child&#39;s learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device  300  typically includes one or more processing units (CPU&#39;s)  310 , one or more network or other communications interfaces  360 , memory  370 , and one or more communication buses  320  for interconnecting these components. Communication buses  320  optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device  300  includes input/output (I/O) interface  330  comprising display  340 , which is typically a touch-screen display. I/O interface  330  also optionally includes a keyboard and/or mouse (or other pointing device)  350  and touchpad  355 , tactile output generator  357  for generating tactile outputs on device  300  (e.g., similar to tactile output generator(s)  167  described above with reference to  FIG.  1 A ), sensors  359  (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s)  165  described above with reference to  FIG.  1 A ). Memory  370  includes high-speed random access memory, such as DRAM, SRAM, DDR RAM or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory  370  optionally includes one or more storage devices remotely located from CPU(s)  310 . In some embodiments, memory  370  stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory  102  of portable multifunction device  100  ( FIG.  1 A ), or a subset thereof. Furthermore, memory  370  optionally stores additional programs, modules, and data structures not present in memory  102  of portable multifunction device  100 . For example, memory  370  of device  300  optionally stores drawing module  380 , presentation module  382 , word processing module  384 , website creation module  386 , disk authoring module  388 , and/or spreadsheet module  390 , while memory  102  of portable multifunction device  100  ( FIG.  1 A ) optionally does not store these modules. 
     Each of the above identified elements in  FIG.  3    are, optionally, stored in one or more of the previously mentioned memory devices. Each of the above identified modules corresponds to a set of instructions for performing a function described above. The above identified modules or programs (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory  370  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  370  optionally stores additional modules and data structures not described above. 
     Attention is now directed towards embodiments of user interfaces (“UI”) that are, optionally, implemented on portable multifunction device  100 . 
       FIG.  4 A  illustrates an exemplary user interface for a menu of applications on portable multifunction device  100  in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device  300 . In some embodiments, user interface  400  includes the following elements, or a subset or superset thereof:
         Signal strength indicator(s)  402  for wireless communication(s), such as cellular and Wi-Fi signals;   Time  404 ;   Bluetooth indicator  405 ;   Battery status indicator  406 ;   Tray  408  with icons for frequently used applications, such as:
           Icon  416  for telephone module  138 , labeled “Phone,” which optionally includes an indicator  414  of the number of missed calls or voicemail messages;   Icon  418  for e-mail client module  140 , labeled “Mail,” which optionally includes an indicator  410  of the number of unread e-mails;   Icon  420  for browser module  147 , labeled “Browser;” and   Icon  422  for video and music player module  152 , also referred to as iPod (trademark of Apple Inc.) module  152 , labeled “iPod;” and   
           Icons for other applications, such as:
           Icon  424  for IM module  141 , labeled “Messages;”   Icon  426  for calendar module  148 , labeled “Calendar;”   Icon  428  for image management module  144 , labeled “Photos;”   Icon  430  for camera module  143 , labeled “Camera;”   Icon  432  for online video module  155 , labeled “Online Video;”   Icon  434  for stocks widget  149 - 2 , labeled “Stocks;”   Icon  436  for map module  154 , labeled “Map;”   Icon  438  for weather widget  149 - 1 , labeled “Weather;”   Icon  440  for alarm clock widget  149 - 4 , labeled “Clock;”   Icon  442  for workout support module  142 , labeled “Workout Support;”   Icon  444  for notes module  153 , labeled “Notes;” and   Icon  446  for a settings application or module, which provides access to settings for device  100  and its various applications  136 .   
               

     It should be noted that the icon labels illustrated in  FIG.  4 A  are merely exemplary. For example, in some embodiments, icon  422  for video and music player module  152  is labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon. 
       FIG.  4 B  illustrates an exemplary user interface on a device (e.g., device  300 ,  FIG.  3   ) with a touch-sensitive surface  451  (e.g., a tablet or touchpad  355 ,  FIG.  3   ) that is separate from the display  450 . Device  300  also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors  357 ) for detecting intensity of contacts on touch-sensitive surface  451  and/or one or more tactile output generators  359  for generating tactile outputs for a user of device  300 . 
       FIG.  4 B  illustrates an exemplary user interface on a device (e.g., device  300 ,  FIG.  3   ) with a touch-sensitive surface  451  (e.g., a tablet or touchpad  355 ,  FIG.  3   ) that is separate from the display  450 . Many of the examples that follow will be given with reference to a device that detects inputs on a touch-sensitive surface that is separate from the display, as shown in  FIG.  4 B . In some embodiments, the touch-sensitive surface (e.g.,  451  in  FIG.  4 B ) has a primary axis (e.g.,  452  in  FIG.  4 B ) that corresponds to a primary axis (e.g.,  453  in  FIG.  4 B ) on the display (e.g.,  450 ). In accordance with these embodiments, the device detects contacts (e.g.,  460  and  462  in  FIG.  4 B ) with the touch-sensitive surface  451  at locations that correspond to respective locations on the display (e.g., in  FIG.  4 B,  460    corresponds to  468  and  462  corresponds to  470 ). In this way, user inputs (e.g., contacts  460  and  462 , and movements thereof) detected by the device on the touch-sensitive surface (e.g.,  451  in  FIG.  4 B ) are used by the device to manipulate the user interface on the display (e.g.,  450  in  FIG.  4 B ) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein. 
     Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures, etc.), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse based input or a stylus input). For example, a drag gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the drag gesture (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously. 
     As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector,” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad  355  in  FIG.  3    or touch-sensitive surface  451  in  FIG.  4 B ) while the cursor is over a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch-screen display (e.g., touch-sensitive display system  112  in  FIG.  1 A  or the touch screen in  FIG.  4 A ) that enables direct interaction with user interface elements on the touch-screen display, a detected contact on the touch-screen acts as a “focus selector,” so that when an input (e.g., a press input by the contact) is detected on the touch-screen display at a location of a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch-screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch-screen display) that is controlled by the user so as to communicate the user&#39;s intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device). 
     As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact or a stylus contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average or a sum) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be readily accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button). 
     In some embodiments, contact/motion module  130  uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device  100 ). For example, a mouse “click” threshold of a trackpad or touch-screen display can be set to any of a large range of predefined thresholds values without changing the trackpad or touch-screen display hardware. Additionally, in some implementations a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter). 
     As used in the specification and claims, the term “characteristic intensity” of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds may include a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second intensity threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more intensity thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective option or forgo performing the respective operation) rather than being used to determine whether to perform a first operation or a second operation. 
     In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface may receive a continuous swipe contact transitioning from a start location and reaching an end location (e.g., a drag gesture), at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location may be based on only a portion of the continuous swipe contact, and not the entire swipe contact (e.g., only the portion of the swipe contact at the end location). In some embodiments, a smoothing algorithm may be applied to the intensities of the swipe contact prior to determining the characteristic intensity of the contact. For example, the smoothing algorithm optionally includes one or more of: an unweighted sliding-average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and/or an exponential smoothing algorithm. In some circumstances, these smoothing algorithms eliminate narrow spikes or dips in the intensities of the swipe contact for purposes of determining a characteristic intensity. 
     The user interface figures described herein (e.g.,  FIGS.  5 A- 5 NN ) optionally include various intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to one or more intensity thresholds (e.g., a contact detection intensity threshold IT 0 , a light press intensity threshold IT L , a deep press intensity threshold IT D  (e.g., that is at least initially higher than I L ), and/or one or more other intensity thresholds (e.g., an intensity threshold I H  that is lower than I L )). This intensity diagram is typically not part of the displayed user interface, but is provided to aid in the interpretation of the figures. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold IT 0  below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures. 
     In some embodiments, the response of the device to inputs detected by the device depends on criteria based on the contact intensity during the input. For example, for some “light press” inputs, the intensity of a contact exceeding a first intensity threshold during the input triggers a first response. In some embodiments, the response of the device to inputs detected by the device depends on criteria that include both the contact intensity during the input and time-based criteria. For example, for some “deep press” inputs, the intensity of a contact exceeding a second intensity threshold during the input, greater than the first intensity threshold for a light press, triggers a second response only if a delay time has elapsed between meeting the first intensity threshold and meeting the second intensity threshold. This delay time is typically less than 200 ms in duration (e.g., 40, 100, or 120 ms, depending on the magnitude of the second intensity threshold, with the delay time increasing as the second intensity threshold increases). This delay time helps to avoid accidental deep press inputs. As another example, for some “deep press” inputs, there is a reduced-sensitivity time period that occurs after the time at which the first intensity threshold is met. During the reduced-sensitivity time period, the second intensity threshold is increased. This temporary increase in the second intensity threshold also helps to avoid accidental deep press inputs. For other deep press inputs, the response to detection of a deep press input does not depend on time-based criteria. 
     In some embodiments, one or more of the input intensity thresholds and/or the corresponding outputs vary based on one or more factors, such as user settings, contact motion, input timing, application running, rate at which the intensity is applied, number of concurrent inputs, user history, environmental factors (e.g., ambient noise), focus selector position, and the like. Exemplary factors are described in U.S. patent application Ser. Nos. 14/399,606 and 14/624,296, which are incorporated by reference herein in their entireties. 
     For example,  FIG.  4 C  illustrates a dynamic intensity threshold  480  that changes over time based in part on the intensity of touch input  476  over time. Dynamic intensity threshold  480  is a sum of two components, first component  474  that decays over time after a predefined delay time p1 from when touch input  476  is initially detected, and second component  478  that trails the intensity of touch input  476  over time. The initial high intensity threshold of first component  474  reduces accidental triggering of a “deep press” response, while still allowing an immediate “deep press” response if touch input  476  provides sufficient intensity. Second component  478  reduces unintentional triggering of a “deep press” response by gradual intensity fluctuations of in a touch input. In some embodiments, when touch input  476  satisfies dynamic intensity threshold  480  (e.g., at point  481  in  FIG.  4 C ), the “deep press” response is triggered. 
       FIG.  4 D  illustrates another dynamic intensity threshold  486  (e.g., intensity threshold I D ).  FIG.  4 D  also illustrates two other intensity thresholds: a first intensity threshold I H  and a second intensity threshold I L . In  FIG.  4 D , although touch input  484  satisfies the first intensity threshold I H  and the second intensity threshold I L  prior to time p2, no response is provided until delay time p2 has elapsed at time  482 . Also in  FIG.  4 D , dynamic intensity threshold  486  decays over time, with the decay starting at time  488  after a predefined delay time p1 has elapsed from time  482  (when the response associated with the second intensity threshold I L  was triggered). This type of dynamic intensity threshold reduces accidental triggering of a response associated with the dynamic intensity threshold I D  immediately after, or concurrently with, triggering a response associated with a lower intensity threshold, such as the first intensity threshold I H  or the second intensity threshold I L . 
       FIG.  4 E  illustrate yet another dynamic intensity threshold  492  (e.g., intensity threshold I D ). In  FIG.  4 E , a response associated with the intensity threshold I L  is triggered after the delay time p2 has elapsed from when touch input  490  is initially detected. Concurrently, dynamic intensity threshold  492  decays after the predefined delay time p1 has elapsed from when touch input  490  is initially detected. So a decrease in intensity of touch input  490  after triggering the response associated with the intensity threshold I L , followed by an increase in the intensity of touch input  490 , without releasing touch input  490 , can trigger a response associated with the intensity threshold I D  (e.g., at time  494 ) even when the intensity of touch input  490  is below another intensity threshold, for example, the intensity threshold I L . See  FIGS.  5 OO- 5 QQ  and the discussion thereof below for additional description of dynamic intensity thresholds and their uses. 
     An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold IT L  to an intensity between the light press intensity threshold IT L  and the deep press intensity threshold IT D  is sometimes referred to as a “light press” input. An increase of characteristic intensity of the contact from an intensity below the deep press intensity threshold IT D  to an intensity above the deep press intensity threshold IT D  is sometimes referred to as a “deep press” input. An increase of characteristic intensity of the contact from an intensity below the contact-detection intensity threshold IT 0  to an intensity between the contact-detection intensity threshold IT 0  and the light press intensity threshold IT L  is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold IT 0  to an intensity below the contact-detection intensity threshold IT 0  is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments IT 0  is zero. In some embodiments, IT 0  is greater than zero. In some illustrations a shaded circle or oval is used to represent intensity of a contact on the touch-sensitive surface. In some illustrations, a circle or oval without shading is used represent a respective contact on the touch-sensitive surface without specifying the intensity of the respective contact. 
     In some embodiments, described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., the respective operation is performed on a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., the respective operation is performed on an “up stroke” of the respective press input). 
     In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., the respective operation is performed on an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances). 
     For ease of explanation, the description of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold. As described above, in some embodiments, the triggering of these responses also depends on time-based criteria being met (e.g., a delay time has elapsed between a first intensity threshold being met and a second intensity threshold being met). 
     User Interfaces and Associated Processes 
     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on an electronic device, such as portable multifunction device  100  or device  300 , with a display, a touch-sensitive surface, and one or more sensors to detect intensities of contacts with the touch-sensitive surface. 
       FIGS.  5 A- 5 NN  illustrate exemplary user interfaces for processing touch inputs in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS.  6 A- 6 E,  7 A- 7 D,  8 A- 8 F, and  9 A- 9 C . Although some of the examples which follow will be given with reference to inputs on a touch-sensitive surface  451  that is separate from the display  450 , in some embodiments, the device detects inputs on a touch-screen display (where the touch-sensitive surface and the display are combined), as shown in  FIG.  4 A . 
       FIG.  5 A  illustrates user interface  5002 -A for a file navigation application displayed on display  450 . In some embodiments, user interface  5002 -A is used to manage, view, access and/or organize files residing on the device (e.g., device  100  or device  300 ).  FIG.  5 A  also illustrates various control objects, such as directory control objects  5006 , and file view control objects  5008 . In  FIG.  5 A , user interface  5002  includes files displayed under a list view. File view control object  5008 - 2 , which corresponds to a list view option, is displayed in a visually distinguished manner from other file view control objects (e.g., object  5008 - 1 ), to indicate to the user of the device that user interface  5002 -A includes the list view option, of the file view options, has been selected. User interface  5002 -A illustrates that the contents of the “Macintosh HD” directory are being displayed, as indicated by title  5012  and directory control object  5006 - 1  being displayed in a visually distinct manner from other directory control objects, such as object  5006 - 2 . 
     User interface  5002  also shows several icons representing files and folders. These file and folder icons are exemplary draggable objects  5004 . In some embodiments, draggable objects  5004  can be moved from one location in a user interface, such as user interface  5002 -A, to another location. In some embodiments, draggable objects refer to user interface objects that are configured to be moved independently (e.g., draggable objects  5004  can be moved without moving user interface  5002 -A, although draggable objects  5004  may also be moved by moving user interface  5002 -A). In some embodiments, control objects such as directory control objects  5006  or file view control objects  5008  cannot be moved independently (e.g., certain control objects  5006  cannot be around within user interface  5002 -A). In some embodiments, draggable objects refer to user interface objects that are configured to be moved individually (e.g., a draggable object  5004  can be moved without moving any other user interface objects, such as another draggable object or a control object). In some embodiments, a control object is configured to initiate, when selected or activated, a predefined operation (e.g., changing a view of a user interface) other than displaying content of a draggable object (e.g., a file or a photo) or launching an application that corresponds to the draggable object.  FIG.  5 A  illustrates the state of display  450  and touch-sensitive surface  451  before an input is detected on touch-sensitive surface  451 . Intensity diagram  5010 -A illustrates the absence of any contact intensity detected on touch-sensitive surface  451 . 
       FIG.  5 B  illustrates a focus selector  5013  (e.g., a cursor), displayed in user interface  5002 -A, over draggable object  5004 - 2 . In  FIG.  5 B , the location of exemplary input that includes contact  5016  on touch-sensitive surface  451  corresponds to the location of the focus selector  5013  in user interface  5002 -A. In some embodiments, focus selector was displayed over a different area in user interface  5002 -A at a location that corresponds to the location of contact  5014  on touch-sensitive surface  451 , before the focus selector  5013  is moved in response to the movement of a contact from the location  5014  to the location  5016 . 
     Contact  5016  is shown to exhibit “minimal” contact with touch-sensitive surface  451 . Intensity diagram  5010 -A illustrates a detected intensity between thresholds IT 0  and IT L , corresponding to the minimal contact detected, of contact  5016 . In some embodiments, a minimal contact with touch-sensitive surface  451  is characterized as any contact detected to have an intensity between thresholds IT 0  and IT L . In some embodiments, contact  5014  also exhibited minimal contact with touch-sensitive surface  451 . In some embodiments, contact  5014  and contact  5016  are part of one continuously detected user interaction (e.g., dragging or tracing gesture) with touch-sensitive surface  451 . As used herein, “minimal contact” refers to a contact having intensity within a certain intensity range, and does not necessarily indicate that intensity of a minimal contact is at a minimum. For example, a contact with touch-sensitive surface  451  may have an intensity below the intensity range for a minimal contact (e.g., intensity below IT 0 ). 
       FIG.  5 C  illustrates an increase in intensity detected at contact  5016 . Intensity diagram  5010 -A illustrates an increase in detected intensity from an intensity below IT L  to an intensity above IT L . In some embodiments, the detected increase in intensity at the location of contact  5016  is considered to be a distinct input from the minimal contact detected at contact  5016  in  FIG.  5 B . For example,  FIG.  5 B  showed a minimal contact input, while  FIG.  5 C  illustrates a “light press” user input at contact  5016 . 
     In some embodiments, detecting a contact intensity above intensity threshold IT L  while focus selector  5013  is displayed over draggable object  504 - 2  results in the satisfaction of one or more object selection criteria. For example, if a light press input is detected on touch-sensitive surface  451  while a cursor is over a file folder, the file folder is selected. In some embodiments, the detected contact intensity must be between IT L  and IT D , in order to satisfy the one or more object selection criteria. In some embodiments, detected contact intensity above IT L  is sufficient to satisfy the one or more object selection criteria without regard to whether or not the detected contact intensity is above or below IT D . 
       FIG.  5 D  illustrates a detected movement  5020  of a user interaction with touch-sensitive surface  451  from contact  5016  to contact  5018 . Intensity diagram  5010 -A shows the detected intensity of the user interaction at contact  5016  before movement  5020  was initiated. Intensity diagram  5010 -B shows the detected intensity of the user interaction at contact  5018  after movement  5020  has concluded. Both contacts have a detected intensity above intensity threshold IT L , and below intensity threshold IT D . In some embodiments, the detected contact intensity must be between IT L  and IT D , in order to satisfy the one or more object selection criteria. In some embodiments, detected contact intensity above IT L  is sufficient to satisfy the one or more object selection criteria without regard to whether or not the detected contact intensity is above or below IT D . 
       FIG.  5 D  also illustrates that in some embodiments, the detected intensity level can fluctuate across a single user interaction, or from contact to contact (e.g., during the movement of a user input from  5016  to  5018 ). In some embodiments, if the fluctuation in detected intensity causes the detected intensity to exceed IT D  or fall below IT L , the one or more object selection criteria will not be satisfied. In some embodiments, if the fluctuation in detected intensity causes the detected intensity to fall below IT L , the one or more object selection criteria will not be satisfied.  FIG.  5 D  shows focus selector  5013  in a new position within user interface  5002 -A, corresponding to the location of contact  5018  and/or movement  5020  detected on touch-sensitive surface  451 . 
     In some embodiments, user interface  5002 -A is said to have one or more regions, where a respective region is associated with one or more operations or display operations. For example, user interface  5002 -A shows at least region  5024  and region  5022 . In this example, region  5024  contains one or more draggable objects  5004 , and region  5022  contains one or more control objects  5008 . In some embodiments, a region contains one or more regions (e.g., sub-regions). For example, each draggable object  5004  within region  5024  is considered to be a respective region or sub-region. In some embodiments, a region is characterized by the display operations which the region is configured to initiate (e.g., changing a file view, changing a calendar view, showing a menu, and changing color or opacity of an object). In some embodiments, a region is characterized by the contents of the region (e.g., containing one or more draggable objects, or containing one or more control objects). 
       FIG.  5 D  illustrates draggable object  5004 - 2  in a visually distinct manner from other draggable objects  5004  (e.g., draggable object  5004 - 1 ), to indicate that draggable object  5004 - 2  is selected. In some embodiments, focus selector  5013  is displayed in conjunction with a representation of the selected object (e.g., a representation of object  5004 - 2 ), when an object is selected. Focus selector  5013  is being displayed over file view control object  5008 - 1 . 
       FIG.  5 D  also illustrates that file view control object  5008 - 1  is visually distinguished in response to focus selector  5013  being displayed over file view control object  5008 - 1  (and prior to detecting that intensity of the contact satisfies intensity threshold IT D ). This visual distinction indicates that file view control object  5008 - 1  is configured to perform a predefined display operation (e.g., displaying contents of the directory in an icon view). 
       FIG.  5 E  illustrates detection of an increase in intensity at contact  5018 . Intensity diagram  5010 -A shows a detected intensity level exceeding intensity threshold IT D . In some embodiments, the detected increase in intensity at the location of contact  5018  is considered to be a distinct input from the contact detected at contact  5018  in  FIG.  5 D . For example,  FIG.  5 D  showed a “light press” input, while  FIG.  5 E  illustrates a “deep press” user input at contact  5018 . 
     In response to detecting the increase (or a change) in intensity at contact  5018 , file view control object  5008 - 1  is activated, and in some embodiments, as shown in  FIG.  5 E , it is displayed in a visually distinct manner to indicate that file view control object  5008 - 1  is activated. In this example, file view control object  5008 - 1  is an icon-view control object, and a display operation is performed to switch the display of the contents of region  5024  from being shown in a list view to being shown in this icon view. In some embodiments, draggable object  5004 - 2  is still shown in a visually distinct manner from the other displayed draggable objects, to indicate that draggable object  5004 - 2  is selected. In some embodiments, detecting that contact  5018  continues to maintain intensity above threshold IT D  does not cause any further display operation to be performed. In some embodiments, detecting a reduction in intensity to a level below threshold IT D  but above IT L  at contact  5018 , maintains selection of draggable object  5004 - 2  but does not cause any further display operation to be performed. 
       FIG.  5 F  illustrates movement of focus selector  5013  (and optionally a representation of selected object  5004 - 2 ), in user interface  5002 -A from the location corresponding to file view control object  5008 - 1  to directory control object  5006 - 2  (e.g., Desktop).  FIG.  5 F  shows that a movement  5026  of a user interaction on touch-sensitive surface  451  is detected from contact  5018  to contact  5028 . Intensity diagram  5010 -A shows the detected intensity of the user interaction at contact  5018  before movement  5026  was initiated. Intensity diagram  5010 -B shows the detected intensity of the user interaction at contact  5028  after movement  5026  has concluded. Both contacts have a detected intensity above intensity threshold IT L , and below IT D . In some embodiments, the detected contact intensity must be between IT L  and IT D , in order to satisfy the one or more object selection criteria. In some embodiments, detected contact intensity above IT L  is sufficient to satisfy the one or more object selection criteria without regard to whether or not the detected contact intensity is above or below IT D . 
       FIG.  5 G  illustrates detection of an increase in intensity at contact  5018 . Intensity diagram  5010 -A shows a detected intensity level exceeding intensity threshold IT D . In some embodiments, the detected increase in intensity at the location of contact  5028  is considered to be a distinct input from the contact detected at contact  5028  in  FIG.  5 F . For example,  FIG.  5 F  showed a “light press” input, while  FIG.  5 G  illustrates a “deep press” user input at contact  5028 . 
     In response to detecting the increase (or a change) in intensity at contact  5028 , directory control object  5006 - 2  is activated, and in some embodiments, as shown in  FIG.  5 G , it is displayed in a visually distinct manner to indicate that it is activated. In this example, directory control object  5006 - 2  corresponds to a file directory called “Desktop”, and a display operation is performed to switch the display of the contents of region  5024  from showing the contents of the “Macintosh HD” directory, to the contents of the “Desktop” directory. In some embodiments, draggable object  5004 - 2  is still selected, but is not shown in user interface  5002 -A because it is still located in a directory that is not being displayed in region  5024  anymore (e.g., in Macintosh HD directory). In some embodiments, detecting that contact  5028  continues to maintain intensity above threshold IT D  at does not cause any further display operation to be performed. In some embodiments, detecting a reduction in intensity to a level below threshold IT D  but above IT L  at contact  5028 , maintains selection of draggable object  5004 - 2  but does not cause any further display operation to be performed. 
       FIG.  5 H  illustrates movement of focus selector  5013  (and optionally a representation of selected object  5004 - 2 ), in user interface  5002 -A from the location corresponding to directory control object  5006 - 2  to region  5024 .  FIG.  5 H  shows that a movement  5030  of a user interaction on touch-sensitive surface  451  is detected from contact  5028  to contact  5032 . Intensity diagram  5010 -A shows the detected intensity of the user interaction at contact  5028  before movement  5030  was initiated. Intensity diagram  5010 -B shows the detected intensity of the user interaction at contact  5032  after movement  5030  has concluded. Both contacts have a detected intensity above intensity threshold IT L , and below IT D . As described above, in some embodiments, the detected contact intensity must be between IT L  and IT D , in order to satisfy the one or more object selection criteria. In some embodiments, detected contact intensity above IT L  is sufficient to satisfy the one or more object selection criteria without regard to whether or not the detected contact intensity is above or below IT D . 
       FIG.  5 H  also shows that in some embodiments, displaying the movement of focus selector  5013  from the region corresponding to directory control object  5006 - 2  to region  5024 , while object  5004 - 2  is selected, includes displaying a representation of selected draggable object  5004 - 2 . In some embodiments, selected draggable object  5004 - 2  is displayed in a visually distinct manner from other draggable objects in user interface  5002 -A as long as draggable object  5004 - 2  is still selected. 
       FIG.  5 I  illustrates no contact being detected on touch-sensitive surface  451 . Intensity diagram  5010 -A indicates the absence of any intensity as well. In response to detecting a decrease in intensity below threshold IT L  (or, optionally failing to meet object selection criteria for one or more other reasons), user interface  5002 -A shows de-selection of draggable object  5004 - 2 , and re-location of draggable object  5004 - 2  to the Desktop directory. In some embodiments, draggable object  5004 - 2  is no longer displayed in a visually distinct manner from other draggable objects in user interface  5002 -A, when it is de-selected. 
       FIG.  5 J  illustrates a user interaction detected on touch-sensitive surface  451 , at contact  5034 . For example, the user interaction is a minimal contact, as described above. Intensity diagram  5010 -A shows a detected intensity level below threshold IT L . In response to detecting the minimal contact at contact  5034 , focus selector  5013  is shown over draggable object  5004 - 3 . 
       FIG.  5 K  illustrates movement of focus selector  5013 , in response to detecting movement  5036  on touch-sensitive surface  451 , from contact  5034  to  5038 . In this example, intensity diagram  5010 -A illustrates that the detected intensity of contact  5034  is below threshold IT L  and intensity diagram  5010 -B illustrates that the detected intensity of contact  5038  is also below threshold IT L . In response to detecting that the intensity level of contact  5034  is below threshold IT L , when focus selector  5013  moves from being displayed over draggable object  5004 - 3  in  FIG.  5 J , to being displayed over directory control object  5006 - 3 , draggable object  5004 - 3  is not selected. 
       FIG.  5 L  illustrates detection of an increase in intensity at contact  5038 . Intensity diagram  5010 -A shows a detected intensity level exceeding intensity threshold IT L . In some embodiments, the detected increase in intensity at the location of contact  5038  is considered to be a distinct input from the contact detected at contact  5038  in  FIG.  5 K . For example,  FIG.  5 K  showed a “minimal contact” input, while  FIG.  5 L  illustrates a “light press” user input at contact  5038 . 
       FIG.  5 L  also shows focus selector  5013  displayed over directory control object  506 - 3 . In response to detecting the increase in intensity at contact  5038 , directory control object  506 - 3  is activated, and in some embodiments, as shown in  FIG.  5 L , it is displayed in a visually distinct manner to indicate that it is activated. In this example, directory control object  5006 - 3  corresponds to a file directory called “Backup Directory”, and a display operation is performed to switch the display of the contents of region  5024  from showing the contents of the “Desktop” directory, to the contents of the “Backup Directory” directory. In some embodiments, detecting maintained intensity above threshold IT L  at contact  5038  does not cause any further display operation to be performed. In some embodiments, directory control object  506 - 3  is configured to perform a display operation in user interface  5002 -A in response to detecting a change in detected intensity at contact  5038  (e.g., a response to a deep press input). 
       FIG.  5 M  illustrates detection of a user interaction with touch-sensitive surface  451  including contact  5040 . In this example, intensity diagram  5010 -A shows a detected intensity level exceeding intensity threshold IT L . Focus selector  5013  is displayed over draggable object  5004 - 4  while the intensity level of contact  5040  is detected to exceed intensity threshold IT L . In this example, one or more object selection criteria are satisfied while focus selector  5013  is displayed over draggable object  5004 - 4 , and object  5004 - 4  is selected. 
       FIG.  5 N  illustrates movement of focus selector  5013  (and optionally a representation of selected object  5004 - 4 ), in user interface  5002 -A from the location corresponding to draggable object  5004 - 4  to control object  5008 - 3  (e.g., a search field).  FIG.  5 N  shows that a movement  5042  of a user interaction on touch-sensitive surface  451  is detected from contact  5040  to contact  5044 . Intensity diagram  5010 -A shows the detected intensity of the user interaction at contact  5040  before movement  5042  was initiated. Intensity diagram  5010 -B shows the detected intensity of the user interaction at contact  5044  after movement  5042  has concluded. Both contacts have a detected intensity above intensity threshold IT L , and below IT D . As described above, in some embodiments, the detected contact intensity must be between IT L  and IT D , in order to satisfy the one or more object selection criteria. In some embodiments, detected contact intensity above IT L  is sufficient to satisfy the one or more object selection criteria without regard to whether or not the detected contact intensity is above or below IT D . 
       FIG.  5 O  illustrates detection of an increase in intensity at contact  5044 . Intensity diagram  5010 -A shows a detected intensity level exceeding intensity threshold IT D . In some embodiments, the detected increase in intensity at the location of contact  5044  is considered to be a distinct input from the contact detected at contact  5044  in  FIG.  5 N . For example,  FIG.  5 N  showed a “light press” input, while  FIG.  5 O  illustrates a “deep press” user input at contact  5044 . In this example, the device (or user interface  5002 -A) is not configured to perform a display operation in response to detection of the “deep press” input while focus selector  5013  is displayed over control object  5008 - 3 . 
       FIG.  5 P  illustrates no contact being detected on touch-sensitive surface  451 . Intensity diagram  5010 -A indicates the absence of any intensity as well. In response to detecting a decrease in intensity below threshold IT L  (or, optionally failing to meet object selection criteria for one or more other reasons) regardless of whether or not a contact is detected on touch-sensitive surface  451 , user interface  5002 -A shows de-selection of draggable object  5004 - 4 , and continued display of object  5004 - 4  in the “Backup Directory” directory. In some embodiments, draggable object  5004 - 4  is no longer displayed in a visually distinct manner from other draggable objects in user interface  5002 -A, when it is de-selected. In this example, control object  5008 - 3  is not configured to perform an operation involving placement of a draggable object  5004  over it. For example, dragging a folder from a directory to a search field and releasing it does not result in performance of any operations associated with the search field. 
       FIG.  5 Q  illustrates user interfaces of two applications or two instances of applications displayed on display  450 . User interface  5002 -A corresponds to an instance of a file management program (e.g., Finder from Apple Inc. of Cupertino, California), and user interface  5002 -B corresponds to another instance of the same file management program. While  FIG.  5 Q  illustrates user interfaces corresponding to two instances of one application, it will be understood that in some embodiments user interface  5002 -A corresponds to a first software application and user interface  5002 -B corresponds to a second software application, distinct from the first software application (e.g., user interface  5002 -A corresponds to an image management application and user interface  5002 -B corresponds to a word processing application). 
       FIG.  5 R  illustrates detection of a user interaction (e.g., a light press input) on touch-sensitive surface  451 , including contact  5046 . Intensity diagram  5010 -A shows a detected intensity level above threshold IT L . In response to detecting the user interaction at contact  5046 , focus selector  5013  is shown over draggable object  5004 - 5 . In this example, one or more object selection criteria are satisfied while focus selector  5013  is displayed over draggable object  5004 - 5 , and object  5004 - 5  is selected. 
       FIG.  5 S  illustrates movement of focus selector  5013  (and optionally a representation of selected object  5004 - 5 ), in user interface  5002 -A from the location corresponding to draggable object  5004 - 5  to a visible portion of user interface  5002 -B.  FIG.  5 S  shows that a movement  5048  of a user interaction on touch-sensitive surface  451  is detected from contact  5046  to contact  5050 . Intensity diagram  5010 -A shows the detected intensity of the user interaction at contact  5046  before movement  5048  was initiated. Intensity diagram  5010 -B shows the detected intensity of the user interaction at contact  5050  after movement  5048  has concluded. Both contacts have a detected intensity above intensity threshold IT L , and below IT D . As described above, in some embodiments, the detected contact intensity must be between IT L  and IT D , in order to satisfy the one or more object selection criteria. In some embodiments, detected contact intensity above IT L  is sufficient to satisfy the one or more object selection criteria without regard to whether or not the detected contact intensity is above or below IT D . 
       FIG.  5 T  illustrates detection of an increase in intensity at contact  5050  in accordance with some embodiments. Intensity diagram  5010 -A shows a detected intensity level exceeding intensity threshold IT D . In some embodiments, the detected increase in intensity at the location of contact  5050  is considered to be a distinct input from the contact detected at contact  5050  in  FIG.  5 S . In this example, the focus selector  5013  is displayed over at least a portion of user interface  5002 -B when the increase in intensity is detected. In some embodiments, user interface  5002 -B is displayed in a visually distinct way from other displayed user interfaces in display  450  (e.g., user interface  5002 -A), in response to detecting focus selector  5013  over at least a portion of user interface  5002 -B, or in response to detecting focus selector  5013  over at least a portion of user interface  5002 -B while the intensity of contact  5050  is above threshold IT L , or in response to detecting focus selector  5013  over at least a portion of user interface  5002 -B while the intensity of contact  5050  is above threshold IT D . For example, user interface  5002 -B is displayed with a glowing border to indicate that the focus selector was successfully moved over to at least a portion of user interface  5002 -B. In some embodiments, user interface  5002 -B is displayed in a visually distinct manner to indicate the ability to perform an operation in response to detecting an intensity of contact  5050  above threshold IT D . 
       FIG.  5 U  illustrates some embodiments, where contact  5050  is detected to have an intensity level maintained at a particular level or range (e.g., between threshold IT L , and threshold IT D ) for at least a predetermined amount of time, while the focus selector  5013  is displayed over at least a portion of user interface  5002 -B. For example, a predetermined time duration threshold of 2 seconds is met by detecting a “light press” input for a time duration  5052  of 2.5 seconds at a location on touch-sensitive surface  451 , corresponding to a visible portion of user interface  5002 -B. 
       FIG.  5 V  illustrates a display operation performed in response to the activities of either  FIG.  5 T  or  FIG.  5 U . In  FIG.  5 V , user interface  5002 -B is displayed in front of user interface  5002 -A, allowing the user of the device to see the contents of user interface  5002 -B. In some embodiments, after the display operation is performed to display user interface  5002 -B over user interface  5002 -A, the intensity level of contact  5050  is detected to have decreased from being above threshold IT D  to being between threshold IT L , and threshold IT D . In some embodiments, the detected contact intensity of contact  5050  is maintained at a level between IT L  and IT D , in order to satisfy the one or more object selection criteria. 
     In some embodiments, draggable object  5004 - 5  is still selected, but is not shown in user interface  5002 -B because object  5004 - 5  is still located in a directory that is being displayed in user interface  5002 -A (e.g., Backup Directory), and user interface  5002 -B is displaying the contents of a different directory (e.g., Macintosh HD). In some embodiments, detecting maintained intensity above threshold IT D  at contact  5050  does not cause any further display operation to be performed. In some embodiments, detecting a reduction in intensity to a level below threshold IT D  but above IT L  at contact  5050 , maintains selection of draggable object  5004 - 5  but does not cause any further display operation to be performed. 
       FIG.  5 W  illustrates movement of focus selector  5013  (and optionally a representation of selected object  5004 - 5 ), in user interface  5002 -B from region  5052  of the user interface to region  5054 .  FIG.  5 W  shows that a movement  5056  of a user interaction on touch-sensitive surface  451  is detected from contact  5050  to contact  5058 . Intensity diagram  5010 -A shows the detected intensity of the user interaction at contact  5050  before movement  5056  was initiated. Intensity diagram  5010 -B shows the detected intensity of the user interaction at contact  5058  after movement  5056  has concluded. Both contacts have a detected intensity above intensity threshold IT L , and below IT D . As described above, in some embodiments, the detected contact intensity must be between IT L  and IT D , in order to satisfy the one or more object selection criteria. In some embodiments, detected contact intensity above IT L  is sufficient to satisfy the one or more object selection criteria without regard to whether or not the detected contact intensity is above or below IT D . 
       FIG.  5 X  illustrates no contact being detected on touch-sensitive surface  451 . Intensity diagram  5010 -A indicates the absence of any intensity as well. In response to detecting a decrease in intensity below threshold IT L  (or, optionally failing to meet object selection criteria for one or more other reasons) regardless of whether or not a contact remains on touch-sensitive surface  451 , user interface  5002 -B shows de-selection of draggable object  5004 - 5 , and re-location of draggable object  5004 - 5  to the “Macintosh HD” directory displayed in user interface  5002 -B. In some embodiments, draggable object  5004 - 5  is no longer displayed in a visually distinct manner from other draggable objects in user interface  5002 -B, when it is de-selected. 
       FIG.  5 Y  illustrates tactile output setting chart  5060 , used to indicate activation of one or more tactile output settings associated with one or more tactile output generators of the device. In some embodiments, one or more tactile output generators are embedded in or are otherwise coupled to touch-sensitive surface  451 . Examples of tactile outputs will be discussed with respect to touch-sensitive surface  451 , but it will be understood that other physical implementations for providing tactile output are possible and intended to be included herein. 
       FIG.  5 Y  illustrates a first tactile output setting being active, and a user interaction including contact  5062  detected on touch-sensitive surface  451 . In some embodiments, the first tactile output setting corresponds to a “silent trackpad mode,” or a mode involving little to no tactile output generation and/or little to no sound generation in conjunction with the performance of display operations. In some embodiments, the silent trackpad mode is a mode of touch-sensitive surface operation in which the features of a normal mode of touch-sensitive surface operation are available at lower intensity thresholds (e.g., instead of pressing to IT L  and then releasing, the user can tap on the touch-sensitive surface and then release to perform a primary operation, and instead of pressing to IT D  and then releasing, the user press to IT L  and then release to perform an alternate operation). This enables users to access all of the functionality of the normal mode of touch-sensitive surface operation without applying as much force. Additionally, in the “silent trackpad” mode of operation, some audible or tactile outputs associated with reaching different intensity levels can be reduced so as to reduce the noise caused by using the device in quiet environments (e.g., environments with low ambient noise, such as libraries, business meetings, classrooms, etc.). 
     Contact  5062  is shown to exhibit minimal contact with touch-sensitive surface  451 . Intensity diagram  5010 -A illustrates a detected intensity between thresholds IT 0  and IT L , corresponding to the minimal contact detected, of contact  5062 . For example, the user interaction including contact  5062  is a light tap on touch-sensitive surface  451 , or a very light, continuously maintained contact. 
     Focus selector  5013  is shown to be displayed over draggable object  5004 - 6 , of user interface  5002 -B. As described above, in some embodiments, respective objects of a user interface displayed on display  450 , are defined to have respective regions. Accordingly, in response to detecting a contact with intensity between thresholds IT 0  and IT L  while the first tactile output setting is active (e.g., silent trackpad mode) and focus selector  5013  is displayed over the region corresponding to draggable object  5004 - 6 , a first display operation is performed. In this example, a folder in the Macintosh HD directory is selected and a display operation is performed to visually distinguish the folder from other un-selected folders in the same directory (e.g., so as to indicate that further user inputs on touch-sensitive surface  451  will affect the selected object, for example a lateral movement of the contact on touch-sensitive surface  451  will cause user interface object  5004 - 6  to be moved on the display, while pressing harder on touch-sensitive surface  451  will cause a contextual menu to be displayed). In this example there is no tactile output generated in conjunction with performing the display operation, but in some embodiments a tactile output is generated. In this example there is no sound generated in conjunction with performing the display operation, but in some embodiments a sound is generated. In some embodiments, a quick tap on touch sensitive surface  451  (between thresholds IT 0  and IT L  that ends within a predetermined time period) causes a primary activation operation to be performed, such as opening the “users” folder represented by icon  5004 - 6 , while a maintained contact on touch sensitive surface  451  (between thresholds IT 0  and IT L  that does not end within a predetermined time period) enables other operations to be performed (e.g., moving user interface object  5004 - 6 ). 
       FIG.  5 Z  illustrates the first tactile output setting being active (e.g., silent trackpad mode), and a user interaction including contact  5062  detected on touch-sensitive surface  451 . Intensity diagram  5010 -A illustrates a detected intensity between thresholds IT L  and IT D , corresponding to contact  5062 . For example, the user interaction including contact  5062  is a medium-intensity, continuously maintained contact (e.g., a contact with intensity between thresholds IT L  and IT D ). 
     Focus selector  5013  is shown to be displayed over draggable object  5004 - 6 , of user interface  5002 -B. In response to detecting focus selector  5013  over the region corresponding to draggable object  5004 - 6  while the first tactile output setting is active and a contact intensity between thresholds IT L  and IT D  is detected, a second display operation is performed. In this example, it is desired to view options relating to a particular folder in the Macintosh HD directory, and a display operation is performed to display a menu  5064  of options relating to the folder. In this example there is no tactile output generated in conjunction with performing the display operation, but in some embodiments a tactile output is generated. In this example there is no sound generated in conjunction with performing the display operation, but in some embodiments a sound is generated. 
     In some embodiments, the second display operation is performed in response to detecting a contact intensity above intensity threshold IT L  while focus selector  5013  is displayed over the region corresponding to draggable object  5004 - 6  and the first tactile output setting is active (e.g., silent trackpad mode) regardless of whether or not the contact intensity is above intensity threshold IT D . 
     In some embodiments, the second display operation is performed in response to detecting a contact intensity between thresholds IT L  and IT D  while focus selector  5013  is displayed over the region corresponding to draggable object  5004 - 6  and the first tactile output setting is active, and no further display operation is performed in response to detecting a contact intensity above intensity threshold IT D  while focus selector  5013  is displayed over the region corresponding to draggable object  5004 - 6  and the first tactile output setting is active. For example, the menu  5064  remains on display even when the contact intensity is above threshold IT D . 
       FIG.  5 AA  illustrates alternate embodiments, where the first tactile output setting is active (e.g., silent trackpad mode), and a user interaction includes contact  5062  detected on touch-sensitive surface  451 . Intensity diagram  5010 -A illustrates a detected intensity above threshold IT D , corresponding to contact  5062 . For example, the user interaction including contact  5062  is a high-intensity, short-duration contact (e.g., a contact with intensity above threshold IT D ). 
     Focus selector  5013  is shown to be displayed over draggable object  5004 - 6 , of user interface  5002 -B. In response to detecting focus selector  5013  over the region corresponding to draggable object  5004 - 6  while the first tactile output setting is active and a contact intensity above threshold IT D  is detected, no display operation is performed. In this example, while the first tactile output setting is active, there is no display operation associated with the detected intensity level. In this example there is no tactile output generated in response to detecting the contact, but in some embodiments a tactile output is generated. In this example there is no sound generated in response to detecting the contact, but in some embodiments a sound is generated. 
       FIG.  5 BB  illustrates a second tactile output setting being active, and a user interaction including contact  5062  detected on touch-sensitive surface  451 . Intensity diagram  5010 -A illustrates a detected intensity between thresholds IT 0  and IT L , corresponding to the minimal contact detected, of contact  5062 . For example, the user interaction including contact  5062  is a light tap on touch-sensitive surface  451 , or a very light, continuously maintained contact. 
     Focus selector  5013  is shown to be displayed over draggable object  5004 - 6 , of user interface  5002 -B. In response to detecting focus selector  5013  over the region corresponding to draggable object  5004 - 6  while the second tactile output setting is active and a contact intensity between thresholds IT 0  and IT L  is detected, no display operation is performed. In this example, while the second tactile output setting is active, there is no display operation associated with the detected intensity level. In this example there is no tactile output generated in response to detecting the contact, but in some embodiments a tactile output is generated. In this example there is no sound generated in response to detecting the contact, but in some embodiments a sound is generated. 
       FIG.  5 CC  illustrates a second tactile output setting being active, and a user interaction including contact  5062  detected on touch-sensitive surface  451 . Intensity diagram  5010 -A illustrates a detected intensity between thresholds IT L  and IT D , corresponding to contact  5062 . For example, the user interaction including contact  5062  is a medium-intensity, continuously maintained contact (e.g., a contact with intensity between thresholds IT L  and IT D ). 
     Focus selector  5013  is shown to be displayed over draggable object  5004 - 6 , of user interface  5002 -B. In response to detecting focus selector  5013  over the region corresponding to draggable object  5004 - 6  while the second tactile output setting is active and a contact intensity between thresholds IT L  and IT D  is detected, a first display operation is performed. In some embodiments a different display operation is performed. In this example, a folder in the Macintosh HD directory is selected and a display operation is performed to visually distinguish the folder from other un-selected folders in the same directory (e.g., so as to indicate that further user inputs on touch-sensitive surface  451  will affect the selected object, for example a lateral movement of the contact on touch-sensitive surface  451  will cause user interface object  5004 - 6  to be moved on the display, while pressing harder on touch-sensitive surface  451  will cause a contextual menu to be displayed). In this example there is a first tactile output  5066  generated in conjunction with performing the display operation, but in some embodiments no tactile output is generated, or a different tactile output is generated. In this example there is no sound generated in conjunction with performing the display operation, but in some embodiments a sound is generated. In some embodiments a particular sound is generated in conjunction with tactile output  5066  (e.g., the first tactile output). In some embodiments, a quick tap on touch sensitive surface  451  (between thresholds IT L  and IT D  that ends within a predetermined time period) causes a primary activation operation to be performed, such as opening the “users” folder represented by icon  5004 - 6 , while a maintained contact on touch sensitive surface  451  (between thresholds IT L  and IT D  that does not end within a predetermined time period) enables other operations to be performed (e.g., moving user interface object  5004 - 6 ). 
       FIG.  5 DD  illustrates a second tactile output setting being active, and a user interaction including contact  5062  detected on touch-sensitive surface  451 . Intensity diagram  5010 -A illustrates a detected intensity above threshold IT D , corresponding to contact  5062 . For example, the user interaction including contact  5062  is a high-intensity, short-duration contact (e.g., a contact with intensity above threshold IT D ). 
     Focus selector  5013  is shown to be displayed over draggable object  5004 - 6 , of user interface  5002 -B. In response to detecting focus selector  5013  over the region corresponding to draggable object  5004 - 6  while the second tactile output setting is active and a contact intensity above threshold IT D  is detected, a second display operation is performed. In some embodiments a different display operation is performed. In this example, it is desired to view options relating to a particular folder in the Macintosh HD directory, and a display operation is performed to display a menu  5064  of options relating to the folder. In this example there is a second tactile output  5068  generated in conjunction with performing the display operation, but in some embodiments no tactile output is generated, or a different tactile output is generated. In this example there is no sound generated in conjunction with performing the display operation, but in some embodiments a sound is generated. In some embodiments a particular sound is generated in conjunction with tactile output  5068  (e.g., the second tactile output), and in some embodiments, the particular sound associated with tactile output  5068  is distinct from a sound associated with another other type of tactile output (e.g., tactile output  5066 ). 
     Figure SEE illustrates region chart  5070  that indicates a type of region in user interface  5002 -A that focus selector  5013  is displayed over. A first region is configured to perform particular display operations in response to the detection of particular types of inputs on touch-sensitive surface  451 , and a second region is configured to perform at least one different display operation in response to the detection of particular types of inputs on touch-sensitive surface  451 . For example, the first region performs a first display operation in response to detecting a “light press” on touch-sensitive surface  451 , and performs a second display operation in response to detecting a “deep press” on surface  451 , while the second region performs a third display operation in response to detecting a “light press” on touch-sensitive surface  451 , and does not perform any display operation in response to detecting a “deep press” on surface  451 . In some embodiments, regions are further characterized by one or more tactile output operations performed in conjunction with display operations. 
     Figure SEE illustrates focus selector  5013  displayed over a first region, and a user interaction including contact  5062  detected on touch-sensitive surface  451 . Intensity diagram  5010 -A illustrates a detected intensity between thresholds IT L  and IT D , corresponding to contact  5062 . For example, the user interaction including contact  5062  is a medium-intensity, continuously maintained contact (e.g., a contact with intensity between thresholds IT L  and IT D ). 
     Focus selector  5013  is shown to be displayed over draggable object  5004 - 6 , of user interface  5002 -B. In response to detecting focus selector  5013  over the region corresponding to draggable object  5004 - 6  (defined as being of the first region type), and a contact intensity between thresholds IT L  and IT D , a first display operation is performed. In some embodiments a different display operation is performed. In this example, a folder in the Macintosh HD directory is selected and a display operation is performed to visually distinguish the folder from other un-selected folders in the same directory. In this example there is a third tactile output  5072  generated in conjunction with performing the display operation, but in some embodiments no tactile output is generated, or a different tactile output is generated. In this example there is no sound generated in conjunction with performing the display operation, but in some embodiments a sound is generated. In some embodiments a particular sound is generated in conjunction with tactile output  5072  (e.g., the third tactile output). 
       FIG.  5 FF  illustrates focus selector  5013  displayed over a first region, and a user interaction including contact  5062  detected on touch-sensitive surface  451 . Intensity diagram  5010 -A illustrates a detected intensity above threshold IT D , corresponding to contact  5062 . For example, the user interaction including contact  5062  is a high-intensity, short-duration contact (e.g., a contact with intensity above threshold IT D ). 
     Focus selector  5013  is shown to be displayed over draggable object  5004 - 6 , of user interface  5002 -B. In response to detecting focus selector  5013  over the region corresponding to draggable object  5004 - 6  (defined as being of the first region type), and a contact intensity above threshold IT D , a second display operation is performed. In this example, it is desired to view options relating to a particular folder in the Macintosh HD directory, and a display operation is performed to display a menu  5064  of options relating to the folder. In this example there is a first tactile output  5066  generated in conjunction with performing the display operation, but in some embodiments no tactile output is generated or a different tactile output is generated. In this example there is no sound generated in conjunction with performing the display operation, but in some embodiments a sound is generated in conjunction with tactile output  5066  (e.g., the first tactile output). 
       FIG.  5 GG  illustrates focus selector  5013  is displayed over a second region (as noted in region chart  5070 ), and a user interaction that includes contact  5074  is detected on touch-sensitive surface  451 . Intensity diagram  5010 -A illustrates a detected intensity between thresholds IT L  and IT D , corresponding to contact  5074 . For example, the user interaction including contact  5074  is a medium-intensity, continuously maintained contact (e.g., a contact with intensity between thresholds IT L  and IT D ). 
       FIG.  5 HH  also illustrates that focus selector  5013  is shown to be displayed over file view control object  5008 - 1 , of user interface  5002 -B. In response to detecting focus selector  5013  over the region corresponding to file view control object  5008 - 1  (defined as being of the second region type), and a contact intensity above threshold IT L  and below threshold IT D , a third display operation is performed. In this example, file view control object  5008 - 1  is activated and the third display operation changes the view of the contents of the “Macintosh HD” directory from being shown in list view (e.g., in  FIG.  5 GG ), to being shown in icon view. In this example there is a (fourth) tactile output  5076  generated in conjunction with performing the display operation, but in some embodiments no tactile output is generated or a different tactile output is generated (e.g., a third tactile output). In this example there is no sound generated in conjunction with performing the display operation, but in some embodiments a sound is generated in conjunction with tactile output  5076  (e.g., the fourth tactile output). 
       FIG.  5 II  illustrates focus selector  5013  displayed over file view control object  5008 - 1  of the second region type, and a user interaction including contact  5074  detected on touch-sensitive surface  451 . Intensity diagram  5010 -A illustrates a detected intensity above threshold IT D , corresponding to contact  5062 . For example, the user interaction including contact  5062  is a high-intensity, short-duration contact (e.g., a contact with intensity above threshold IT D ). In this example, while the focus selector  5013  is detected over an object of the second region type, there is no display operation associated with the detected intensity level. In this example there is a second tactile output  5068  generated in conjunction with performing the display operation, but in some embodiments no tactile output is generated, or a different tactile output is generated. In this example there is no sound generated in conjunction with performing the display operation, but in some embodiments a sound is generated. In some embodiments a particular sound is generated in conjunction with tactile output  5068  (e.g., the second tactile output), and in some embodiments, the particular sound associated with tactile output  5068  is distinct from a sound associated with another other type of tactile output (e.g., tactile output  5066 ). 
       FIG.  5 JJ  illustrates that focus selector  5013  is displayed over a control object  5008 - 4  of a third region type (as noted in region chart  5070 ), and a user interaction that includes contact  5078  is detected on touch-sensitive surface  451 . Intensity diagram  5010 -A illustrates a detected intensity between thresholds IT L  and IT D , corresponding to contact  5078 . For example, the user interaction including contact  5074  is a medium-intensity, continuously maintained contact (e.g., a contact with an intensity between thresholds IT L  and IT D ). In response to detecting the intensity level, no display operation is performed. In this example there is a third tactile output  5072  generated in response to detecting the intensity level of contact  5078 , but in some embodiments no tactile output is generated, or a different tactile output is generated. In some embodiments a particular sound is generated in conjunction with tactile output  5072  (e.g., the third tactile output), and in some embodiments, a particular sound associated with tactile output  5072  is distinct from a sound associated with another other type of tactile output (e.g., a tactile output that indicates that. 
       FIG.  5 KK  illustrates an increase in intensity detected at contact  5078 . Intensity diagram  5010 -A illustrates a detected intensity above threshold IT D , corresponding to contact  5078 . For example, the user interaction including contact  5062  is a high-intensity, short-duration contact (e.g., a contact with intensity above threshold IT D ). In this example, in response to detecting the intensity level, no display operation is performed. In this example there is a second tactile output  5068  generated in response to detecting the intensity level of contact  5078 , but in some embodiments no tactile output is generated, or a different tactile output is generated. In some embodiments a particular sound is generated in conjunction with tactile output  5068  (e.g., the second tactile output), and in some embodiments, a particular sound associated with tactile output  5068  is distinct from a sound associated with another other type of tactile output. 
       FIG.  5 LL  illustrates an exemplary settings user interface or control panel  5080  for changing one or more tactile outputs and/or one or more activation criteria in accordance with some embodiments. For example, control panel  5080  has one or more control objects  5082  for adjusting the magnitude of a first tactile output  5084 . In this example, the magnitude control objects  5082  are discrete control objects that each correspond to a particular setting, but in some embodiments, the magnitude of first tactile output  5084  can be adjusted using a continuous control object such as control object  5086 . Control object  5086  allows for an adjustment of the duration of first tactile output  5084 . In some embodiments the duration of the first tactile output can be adjusted using discrete control objects such as control objects  5082 . 
       FIG.  5 LL  also illustrates control objects corresponding to adjustment of first activation criteria  5090 . In some embodiments, activation criteria such as first activation criteria  5090  include intensity threshold control objects  5092 . In some embodiments, intensity threshold control objects  5092  are tied to control objects  5082  for adjusting the magnitude of a tactile output. In some embodiments, the magnitude of first tactile output  5084  and the intensity threshold of first activation criteria  5090  are both adjusted using one or more continuous control objects (e.g., a slider bar that adjusts both settings simultaneously). While the above description pertains to a first tactile output  5084  and first activation criteria  5090 , in some embodiments the same principles apply to one or more other tactile outputs and activation criteria. In some embodiments, a respective tactile output setting has a corresponding activation criteria setting. In some embodiments, a change to one setting (or pair of settings), causes a change to another setting (or pair of settings). 
     In some embodiments, as shown in  FIG.  5 LL , control panel  5080  has a user interface element  5098  for applying changes to one or more settings in control panel  5080 . In some embodiments, control panel  5080  has a user interface element  5094  for saving changes to one or more settings and exiting control panel  5080 . In some embodiments, control panel  5080  has a user interface element  5096  for canceling any changes made to one or more settings and ceasing to display control panel  5080  in display  450 . 
       FIGS.  5 MM- 5 NN  illustrate exemplary settings user interfaces or control panels for changing one or more tactile outputs and/or one or more activation criteria in accordance with some embodiments. 
     The settings user interfaces illustrated in  FIGS.  5 MM- 5 NN  are used to adjust settings for operations of a touch-sensitive surface (e.g., a trackpad). In  FIGS.  5 MM- 5 NN , the settings user interfaces include options that are not directly related to intensity based user inputs. 
     In  FIG.  5 MM , the intensity threshold control objects  5088  are radio buttons that correspond to low, medium, and high intensity levels. Based on user selection of one of the radio buttons, intensity thresholds (e.g., IT L  and IT D ) are changed. For example, IT L  and IT D  are increased in response to selection of the radio button that corresponds to high intensity thresholds (from previous selection of the radio button that corresponds to low or medium intensity thresholds). 
     In  FIG.  5 NN , the intensity threshold control object  5089  is a slider that corresponds to a plurality of intensity levels. In  FIG.  5 NN , the intensity threshold control object  5089  provides more than three intensity levels so that a finer adjustment of the intensity levels is allowed. 
     In some embodiments, tactile output settings are adjusted based on the user interaction with the intensity threshold control object(s) (e.g., user selection of one of the radio buttons in  FIG.  5 MM  or user adjustment of the slider in  FIG.  5 NN ). In some embodiments, delay time between a light press and a deep press is adjusted based on the user interaction with the intensity threshold control object(s). 
     The settings user interfaces or control panels illustrated in  FIGS.  5 MM- 5 NN  provide simple user interfaces for easy adjustment of the intensity-based operations of the electronic device, thereby reducing the number, extent, and/or nature of the inputs from the user. 
       FIGS.  5 OO- 5 QQ  are exemplary intensity diagrams in accordance with some embodiments. 
       FIG.  5 OO  illustrates three intensity diagrams (left, center, and right) in accordance with some embodiments. The left intensity diagram in  FIG.  5 OO  includes multiple intensity thresholds, such as primary activation intensity threshold (e.g., an intensity threshold that an intensity of a contact needs to exceed in order to activate a first operation), primary activation release threshold (e.g., an intensity threshold that an intensity of a contact needs to fall below, after exceeding the primary activation intensity threshold, in order to cease the first operation), deep activation intensity threshold (e.g., an intensity threshold that an intensity of a contact needs to exceed in order to activate a second operation in some embodiments), and deep release intensity threshold (e.g., an intensity threshold that an intensity of a contact needs to fall below, after exceeding the deep activation intensity threshold, in order to cease the second operation). 
     The center intensity diagram in  FIG.  5 OO  illustrates an intensity of a contact that changes over time (e.g., a light press input). In the center intensity diagram in  FIG.  5 OO , the intensity of the contact increases over time to exceed the primary activation intensity threshold, thereby activating the first operation. The center intensity diagram in  FIG.  5 OO  also illustrates that, subsequent to the intensity of the contact exceeds the primary activation intensity threshold, the intensity of the contact decreases and falls below the primary release intensity threshold. 
     The right intensity diagram in  FIG.  5 OO  illustrates an intensity of a contact that changes over time and exceeds the deep activation intensity threshold (e.g., a deep press input). In some embodiments, when the intensity of the contact exceeds the deep activation intensity threshold, the second operation (e.g., a deep press operation) is activated. 
     In some cases, users unintentionally press the touch-sensitive surface with high intensity (e.g., a deep press input) without an intention to activate the second operation (e.g., a deep press operation). The unintentional deep press input may be due to variation in perception of intensity from person to person, variation in finger strength from person to person, variation in perception of intensity for an individual over time, and/or variation in intensity for an individual over time (e.g., decreased intensity due to fatigue or increased intensity due to reduced sensitivity of the individual), etc. An unintentional activation of the second operation (e.g., a deep press operation) is inefficient, wastes time, and degrades the user experience. Thus, it is important to reduce “unintentional” activations of the second operation (e.g., a deep press operation). 
     The intensity diagrams in  FIGS.  5 PP- 5 QQ  illustrate features that reduce unintentional activation of a deep press operation. 
       FIG.  5 PP  illustrates three intensity diagrams (left, center, and right). The left intensity diagram in  FIG.  5 PP  illustrates a decaying intensity threshold offset for the deep activation intensity threshold that decreases over time. In some embodiments, the decaying intensity threshold offset decreases from the time at which an intensity of a contact satisfies a lower activation intensity threshold (e.g., primary activation intensity threshold in  FIG.  5 OO ). In some embodiments, the decaying intensity threshold offset decreases after a predetermined duration (e.g., 10 ms, 20 ms, 30 ms, 40 ms, 50 ms, 60 ms, 70 ms, 80 ms, 90 ms, 100 ms, 110 ms, 120 ms, 130 ms, 140 ms, 150 ms, 160 ms, 170 ms, 180 ms, 190 ms, 200 ms, 300 ms, 400 ms, 500 ms, etc.) after the time at which an intensity of a contact satisfies the lower activation intensity threshold. In some embodiments, the decaying intensity threshold offset decreases in accordance with a predefined time constant (e.g., 0.1 s, 0.2 s, 0.3 s, 0.4 s, 0.5 s, 0.6 s, 0.7 s, 0.8 s, 0.9 s, 1.0 s, 1.1 s, 1.2 s, 1.3 s, 1.4 s, 1.5 s, 1.6 s, 1.7 s, 1.8 s, 1.9 s, 2 s, 3 s, 4 s, 5 s, etc.). In some embodiments, the offset starts from a high intensity threshold. When this decaying intensity threshold offset is used, an intensity of a contact needs to exceed the increased initial threshold to activate a deep press operation. Thus, this decaying intensity threshold offset prevents a quick high intensity press input from activating a deep press operation. 
     The center intensity diagram in  FIG.  5 PP  illustrates an intensity threshold offset for the deep activation intensity threshold that trails an intensity of a contact (e.g., “trailing force” intensity threshold offset in  FIG.  5 PP , which trails the “input force” of a contact in  FIG.  5 PP ) in accordance with some embodiments. In some embodiments, the trailing force intensity offset is determined based on an intensity of the contact over time. For example, the trailing force intensity threshold offset in the center intensity diagram in  FIG.  5 PP  is determined by processing intensity of the contact with a low pass filter (e.g., with a predefined time constant (e.g., 0.1 s, 0.2 s, 0.3 s, 0.4 s, 0.5 s, 0.6 s, 0.7 s, 0.8 s, 0.9 s, 1.0 s, 1.1 s, 1.2 s, 1.3 s, 1.4 s, 1.5 s, 1.6 s, 1.7 s, 1.8 s, 1.9 s, 2 s, 3 s, 4 s, 5 s, etc.). When this trailing force intensity threshold offset is used, the deep activation intensity threshold is increased as an intensity of a contact increases (e.g., when a user applies higher intensity while dragging a contact). Thus, this trailing force intensity threshold offset reduces activation of a deep press operation by a gradual increase in intensity of a contact over time (e.g., during a drag). 
     The right intensity diagram in  FIG.  5 PP  illustrates that a first offset that decreases over time (e.g., the decaying intensity threshold offset described with respect to the left intensity diagram in  FIG.  5 PP ), a second offset that changes over time based on an intensity of a contact on the touch-sensitive surface (e.g., the trailing force intensity threshold offset described with respect to the center intensity diagram in  FIG.  5 PP ), and/or a sum of the first offset and the second offset (e.g., a weighted sum of the first offset and the second offset, with equal or different weights) may be used to reduce unintentional activation of a deep press operation. 
       FIG.  5 QQ  illustrates two intensity versus time diagrams (top and bottom). The top intensity versus time diagram in  FIG.  5 QQ  illustrates that a dynamic (time varying) intensity threshold  5102  includes a sum of the first offset and the second offset. In the top intensity diagram in  FIG.  5 QQ , an intensity  5202  of a contact does not exceed the intensity threshold  5102 , and thus a deep press operation is not activated. 
     The bottom intensity diagram in  FIG.  5 QQ  illustrates that another dynamic (time varying) intensity threshold  5104 . The intensity threshold  5104  is offset from the intensity threshold  5102  by an intensity threshold offset for a user that has been determined based on past inputs from the user. For example, for a user who has a tendency to provide high intensity inputs, the intensity threshold offset is increased (e.g., by the heavy clicker offset in  FIG.  5 QQ ) to prevent unintentional activation of a deep press operation. In some embodiments, the intensity offset for a user is a time-independent offset for a particular input (e.g., the intensity offset for a user does not change during the course of the particular input, although other intensity offsets for the deep activation intensity threshold, such as the first offset and the second offset, may change over time during the course of the particular input). 
       FIGS.  6 A- 6 E  illustrate a flow diagram of a method  600  of enabling interaction with one or more control objects in a user interface, in accordance with some embodiments. The method  600  is performed at an electronic device (e.g., device  300 ,  FIG.  3   , or portable multifunction device  100 ,  FIG.  1 A ) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method  600  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, the method  600  provides an intuitive way to interact with one or more control objects in a user interface. The method reduces the number, extent, and/or nature of the inputs from a user when interacting with one or more control objects in a user interface, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to interact with one or more control objects in a user interface faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays ( 602 ) on the display, a user interface of a first software application that includes one or more draggable objects (e.g., file icons, folder icons, calendar entries, such as folder icon  5004 - 2  in  FIG.  5 B ) and one or more control objects distinct from the one or more draggable objects (e.g., buttons, toolbars, menus, such as file view control object  5008 - 1  in  FIG.  5 B ). While the device displays the user interface of the first software application, the device performs at least the following operations. 
     The device detects ( 604 ) a contact (e.g., contact  5016  in  FIG.  5 C ) on the touch-sensitive surface at a first location while a focus selector is displayed over a first draggable object of the one or more draggable objects displayed on the display. 
     After detecting the contact on the touch-sensitive surface at the first location, the device detects ( 606 ) a movement of the contact across the touch-sensitive surface to a second location that corresponds to a first control object of the one or more control objects displayed on the display (e.g., movement  5020  in  FIG.  5 D  from location  5016  to location  5018  on touch-sensitive surface  451 ). 
     In some embodiments, in response to detecting movement of the contact from the first location to the second location, and in accordance with a determination that the contact at the first location does not satisfy the object selection criteria, the device moves ( 608 ) the focus selector to the first control object in accordance with the movement of the contact across the touch-sensitive surface to the first control object without moving the first draggable object to the first control object (e.g., if the contact at the first location does not satisfy the object selection criteria, the first draggable object is not selected and the focus selector moves without the first draggable object). In some embodiments, in accordance with a determination that the contact at the second location satisfies the second intensity criteria, the device performs ( 610 ) the first predetermined operation that corresponds to activation of the first control object without moving the first draggable object to the first control object (e.g., if the focus selector moves over to file view control object  5008 - 1 , icon view control object  5008 - 1  is activated and contents of the directory is displayed in an icon view). In some embodiments, the method includes, in accordance with a determination that the contact at the second location satisfies the first intensity criteria, performing the first predetermined operation that corresponds to activation of the first control object. 
     In response to detecting movement of the contact from the first location to the second location, and in accordance with a determination that the contact at the first location satisfies object selection criteria, the device moves ( 612 ) the first draggable object to the first control object in accordance with the movement of the contact across the touch-sensitive surface to the first control object (e.g.,  FIG.  5 D ). 
     In some embodiments, in response to moving the first draggable object to the first control object, and in accordance with a determination that the first software application is configured to perform the first predetermined operation in response to detecting a contact at the second location that satisfies the first intensity criteria, the device visually distinguishes ( 614 ) the first control object prior to determining that the contact satisfies the first intensity criteria (e.g., file view control object  5008 - 1  is visually distinguished in  FIG.  5 D ). 
     Furthermore, in some embodiments, the device detects ( 616 ) a movement of the contact across the touch-sensitive surface to a fourth location that corresponds to a second control object of the one or more control objects (e.g.,  FIG.  5 N ). In some embodiments, in accordance with a determination that the first software application is not configured to perform a predetermined operation in response to detecting a contact at the fourth location that satisfies the first intensity criteria, the device foregoes ( 618 ) visually distinguishing the second control object (e.g., in  FIG.  5 N , control object  5008 - 3  is not visually distinguished). 
     In accordance with a determination that the contact at the second location satisfies first intensity criteria, the device performs ( 620 ) a first predetermined operation that corresponds to activation of the first control object (e.g., displaying contents of the directory in an icon view, as shown in  FIG.  5 E ). 
     In some embodiments, the user interface includes ( 622 ) multiple distinct portions, a first portion of the multiple distinct portions (e.g., region  5022 ) includes the first control object, and performing the first predetermined operation that corresponds to activation of the first control object includes changing a second portion (e.g., region  5024 ), distinct from the first portion, of the multiple distinct portions. In some embodiments, changing the second portion includes forgoing a change to the first portion. For example, in  FIG.  5 E , performing the first predetermined operation updates region  5024 . In some embodiments, changing the second portion includes maintaining the first portion. 
     In some embodiments, the first software application is a calendar application ( 624 ), the user interface of the first software application includes multiple time-period user interface elements (e.g., control objects) in the first portion, the one or more draggable objects are one or more calendar entry objects (e.g., one or more graphical representations of calendar events), a respective time-period user interface element of the multiple time-period user interface elements corresponds to a predefined unit of time (e.g., day, week, month, and/or year), the second portion of the user interface of the first software application, prior to the determination that the contact at the second location satisfies the first intensity criteria, includes a calendar view that corresponds to a first unit of time (e.g., a day view), and changing the second portion includes replacing the calendar view that corresponds to a first unit of time with a calendar view that corresponds to a second unit of time that is distinct from the first unit of time (e.g., a month view). 
     In some embodiments, the first software application is a file system navigation application ( 626 ), also called a file manager or a file browser (e.g., Finder, Windows Explorer, and File Explorer) (e.g., the user interface of a file system navigation application in  FIG.  5 B ). In some embodiments, the user interface of the first software application includes multiple file view control objects (e.g., an object to show files as icons, and an object to show files in a list) in the first portion, the one or more draggable objects are one or more of file icons and/or folder icons, and a respective file view control object of the multiple file view control objects corresponds to a distinct file view type (e.g., an icon view, a list view, a column view, and/or a cover view). In some embodiments, the second portion of the user interface, prior to the determination that the contact at the second location satisfies the first intensity criteria, includes a file view of a first file view type (e.g., a list view), and changing the second portion includes replacing the file view of the first file view type with a file view of a second file view type that is distinct from the file view of the first file view type (e.g., an icon view). 
     In some embodiments, the device, subsequent to moving the first draggable object to the first control object and changing the second portion, detects ( 628 ) a movement of the contact across the touch-sensitive surface to a third location that corresponds to the changed second portion on the display. For example, changing the second portion of the display includes replacing the calendar view from a day view to a month view. In another example, changing the second portion of the display includes replacing display of contents in a first directory with display of contents in a second directory (e.g.,  FIG.  5 H ). Furthermore, in some embodiments, the device moves ( 630 ) the first draggable object to a location, in the changed second portion, that corresponds to the third location on the touch-sensitive surface in accordance with the movement of the contact across the touch-sensitive surface to the third location. Furthermore, in some embodiments, in accordance with a determination that the contact at the third location does not satisfy the object selection criteria, the device drops ( 632 ) the first draggable object at the location, in the changed second portion, that corresponds to the third location on the touch-sensitive surface (e.g.,  FIG.  5 I ). 
     In some embodiments, the object selection criteria include ( 634 ) second intensity criteria. For example, a contact with intensity between IT L  and IT D  is used to select a draggable object. 
     In some embodiments, the device concurrently displays ( 636 ) an entirety of the user interface of the first software application with a portion of a user interface of a second software application adjacent to the user interface of the first software application (e.g., user interface  5002 -A and user interface  5002 -B in  FIG.  5 Q ). In some embodiments, the user interface of the first software application is in contact with the portion of the user interface of the second software application. In some embodiments, the user interface of the first software application appears to overlie a portion of the user interface of the second software application. 
     Furthermore, in some embodiments, in accordance with the determination that the contact at the first location satisfies the object selection criteria, the device detects ( 638 ) a movement of the contact across the touch-sensitive surface to a fifth location that corresponds to the displayed portion of the user interface of the second software application on the display (e.g.,  FIG.  5 S ). In some embodiments, the device moves ( 640 ) the first draggable object to the displayed portion of the user interface of the second software application in accordance with the movement of the contact across the touch-sensitive surface to the fifth location. In some embodiments, the contact continues to satisfy the object selection criteria during the movement of the contact across the touch-sensitive surface to the fifth location. 
     In some embodiments, in response to a determination that the contact at the fifth location satisfies the first intensity criteria (e.g., intensity of contact satisfying threshold IT D  in  FIG.  5 T ), the device replaces ( 642 ) a concurrent display of the entirety of the user interface of the first software application and the portion of the user interface of the second software application with a concurrent display of an entirety of the user interface of the second software application and a portion of the user interface of the first software application adjacent to the user interface of the second software application (e.g., user interface  5002 -B and user interface  5002 -A in  FIG.  5 V ). In some embodiments, the user interface of the second software application appears to overlie a portion of the user interface of the first software application. 
     In some embodiments, in response to a determination that the contact at the fifth location does not satisfy the first intensity criteria, the device determines ( 644 ) a time period during which the contact remains at the fifth location, and in response to a determination that the time period satisfies time-based activation criteria (e.g., focus selector  5013  remains over user interface  5002 -B and satisfies the time-based activation criteria, as shown in  FIG.  5 U ), the device replaces the concurrent display of the entirety of the user interface of the first software application and the portion of the user interface of the second software application with the concurrent display of an entirety of the user interface of the second software application and the portion of the user interface of the first software application adjacent to the user interface of the second software application (e.g., user interface  5002 -B and user interface  5002 -A in  FIG.  5 V ). 
     It should be understood that the particular order in which the operations in  FIGS.  6 A- 6 E  have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods  700 ,  800 , and  900 ) are also applicable in an analogous manner to method  600  described above with respect to  FIGS.  6 A- 6 E . For example, the contacts, inputs, user interface objects, intensity thresholds, focus selectors, and criteria described above with reference to method  600  optionally have one or more of the characteristics of the contacts, inputs, user interface objects, intensity thresholds, focus selectors, and criteria described herein with reference to other methods described herein (e.g., methods  700 ,  800 , and  900 ). For brevity, these details are not repeated here. 
       FIGS.  7 A- 7 D  illustrate a flow diagram of a method  700  of performing operations in conjunction with generating tactile outputs, in accordance with some embodiments. The method  700  is performed at an electronic device (e.g., device  300 ,  FIG.  3   , or portable multifunction device  100 ,  FIG.  1 A ) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the device includes one or more tactile output generators. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method  700  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, the method  700  provides an intuitive way to perform operations in conjunction with generating tactile outputs. The method reduces the cognitive burden on a user when performing operations in conjunction with generating tactile outputs, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to perform operations in conjunction with generating tactile outputs faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays ( 702 ), on the display of the electronic device, a user interface of a first software application. While displaying the user interface of the first software application, the device performs at least the following operations. 
     The device detects ( 704 ) a first input (e.g., a tap gesture) that includes a contact detected on the touch-sensitive surface, wherein the contact included in the first input is associated with a respective region of the user interface of the first software application that is associated with a first operation (e.g., a response to a “light press” or “left click”) and a second operation (e.g., a response to a “deep press,” “right click,” or “option+click”). In some embodiments, the first operation is a first display operation and the second operation is a second display operation. 
     In response to detecting the first input (e.g., a tap gesture), and in accordance with a determination that a first tactile output setting is active (e.g., silent trackpad mode) for the first input, the device performs ( 706 ) the first operation without generating a tactile output. In some embodiments, the first tactile output setting is active for the first input, based on a location of the contact, a location of the focus selector corresponding to the contact, or a system-wide setting or condition. For example, as illustrated in  FIG.  5 Y , tactile output setting chart  5060  indicates that the first tactile output setting is active. In response to detecting the input associated with contact  5062 , having an intensity level below threshold IT L , the “Users” folder (object  5004 - 6 ) is highlighted in display  450  (an exemplary first display operation is performed).  FIG.  5 Y  also illustrates performance of this operation without generating a tactile output. 
     In response to detecting the first input, and in accordance with a determination that a second tactile output setting is active (e.g., non-silent trackpad mode) for the first input, the device forgoes ( 708 ) performing the first operation. For example, as illustrated in  FIG.  5 BB , tactile output setting chart  5060  indicates that the second tactile output setting is active. In response to detecting the input associated with contact  5062 , having an intensity level below threshold IT L , the “Users” folder (object  5004 - 6 ) is not highlighted in display  450  (an exemplary first display operation is not performed).  FIG.  5 BB  also illustrates performance of this operation without generating a tactile output. 
     The device detects ( 710 ) a second input (e.g., a light press) that includes a contact detected on the touch-sensitive surface, wherein the contact included in the second input is associated with the respective region of the user interface of the first software application that is associated with the first operation (e.g., a response to a “light press” or “left click”) and the second operation (e.g., a response to a “deep press,” “right click,” or “option+click”) and the second input is different from the first input. 
     In response to detecting the second input, and in accordance with a determination that the second tactile output setting is active (e.g., non-silent trackpad mode) for the second input, the device performs ( 712 ) the first operation in conjunction with generating a first tactile output associated with the first operation. For example, as illustrated in  FIG.  5 CC , tactile output setting chart  5060  indicates that the second tactile output setting is active. In response to detecting the input associated with contact  5062 , having an intensity level above threshold IT L , and below threshold IT D , the “Users” folder (object  5004 - 6 ) is highlighted in display  450  (an exemplary first display operation is performed).  FIG.  5 CC  also illustrates performance of this operation in conjunction with generating a first tactile output. 
     In some embodiments, the first tactile output ( 714 ) lasts for less than a predetermined time. In some embodiments, duration of the first tactile output is independent of duration of the contact remaining on the touch-sensitive surface. In some embodiments, the second tactile output lasts for less than the predetermined time. In some embodiments, duration of a respective tactile output is less than 0.5 seconds. In some embodiments, the duration of the respective predetermined tactile output is less than 0.4 seconds. In some embodiments, the duration of the respective predetermined tactile output is less than 0.3 seconds. In some embodiments, the duration of the respective predetermined tactile output is less than 0.2 seconds. In some embodiments, the duration of the respective predetermined tactile output is less than 0.1 seconds. 
     In response to detecting the second input, and in accordance with a determination that the first tactile output setting is active (e.g., silent trackpad mode) for the second input, the device performs ( 716 ) the second operation. In some embodiments, the device performs the second operation instead of the first operation, or without performing the first operation, and/or without generating the first tactile output. For example, as illustrated in  FIG.  5 Z , tactile output setting chart  5060  indicates that the first tactile output setting is active. In response to detecting the input associated with contact  5062 , having an intensity level above threshold IT L , and below threshold IT D , a menu associated with the “Users” folder (object  5004 - 6 ) is displayed in display  450  (an exemplary second display operation is performed).  FIG.  5 Z  also illustrates performance of this operation without generating a first tactile output and without performing the first display operation (e.g., highlighting the “Users” folder). 
     In some embodiments, in response to detecting the second input, in accordance with the determination that the first tactile output setting is active for the second input (e.g., silent trackpad mode), the device performs ( 718 ) the second operation without performing the first operation. 
     In some embodiments, in response to detecting the second input, in accordance with the determination that the first tactile output setting is active for the second input (e.g., silent trackpad mode), the device forgoes ( 720 ) generation of the first tactile output. 
     In some embodiments, in response to detecting the second input, in accordance with the determination that the first tactile output setting is active for the second input (e.g., silent trackpad mode), the device forgoes ( 722 ) generation of a second tactile output associated with the second operation. 
     In some embodiments, the device detects ( 724 ) a third input (e.g., a deep press) that includes a contact detected on the touch-sensitive surface, wherein the contact included in the third input is associated with the respective region of the user interface of the first software application that is associated with the first operation (e.g., a response to a “light press” or “left click”) and the second operation (e.g., a response to a “deep press,” “right click,” or “option+click”) and the third input is different from the first input and the second input. In some embodiments, the contact in the second input and the contact in the third input are ( 726 ) a same contact that is continuously detected on the touch-sensitive surface between the second input and the third input. In some embodiments, the second input satisfies ( 728 ) a first intensity threshold and the contact in the third input satisfies a second intensity threshold that is higher than the first intensity threshold. 
     In some embodiments, in response to detecting the third input (e.g., a deep press), and in accordance with a determination that the second tactile output setting is active (e.g., non-silent trackpad mode) for the third input, the device performs ( 730 ) the second operation in conjunction with generating a second tactile output associated with the second operation. For example, as illustrated in  FIG.  5 DD , tactile output setting chart  5060  indicates that the second tactile output setting is active. In response to detecting the input associated with contact  5062 , having an intensity level above threshold IT D , a menu associated with the “Users” folder (object  5004 - 6 ) is displayed in display  450  (an exemplary second display operation is performed).  FIG.  5 Z  also illustrates performance of this operation in conjunction with generating a second tactile output and without performing the first display operation (e.g., highlighting the “Users” folder). 
     In some embodiments, in response to detecting the third input (e.g., a deep press), and in accordance with a determination that the first tactile output setting is active (e.g., silent trackpad mode) for the third input, the device forgoes ( 732 ) generation of the second tactile output. In some embodiments, in response to detecting the third input and in accordance with the determination that the first tactile output setting is active (e.g., silent trackpad mode), the device forgoes ( 734 ) repeating the second operation. For example, as illustrated in  FIG.  5 AA , tactile output setting chart  5060  indicates that the first tactile output setting is active. In response to detecting the input associated with contact  5062 , having an intensity level above threshold IT D , the “Users” folder is not highlighted (an exemplary first display operation is not performed), and a menu associated with the “Users” folder (object  5004 - 6 ) is not displayed in display  450  (an exemplary second display operation is not performed).  FIG.  5 AA  also illustrates forgoing performance of the second operation in conjunction with forgoing generating any tactile output and without performing the first display operation (e.g., highlighting the “Users” folder). 
     In some embodiments, the second tactile output includes ( 736 ) an audible component that is louder than an audible component of the first tactile output. In some embodiments, the first tactile output has ( 738 ) a first tactile output intensity and the second tactile output has a second tactile output intensity that is greater than the first tactile output intensity. 
     It should be understood that the particular order in which the operations in  FIGS.  7 A- 7 D  have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods  600 ,  800 , and  900 ) are also applicable in an analogous manner to method  700  described above with respect to  FIGS.  7 A- 7 D . For example, the contacts, inputs, operations, tactile output settings, tactile output intensity, intensity thresholds, regions and tactile outputs described above with reference to method  700  optionally have one or more of the characteristics of the contacts, inputs, operations, tactile output settings, tactile output intensity, intensity thresholds, regions and tactile outputs described herein with reference to other methods described herein (e.g., methods  600 ,  800 , and  900 ). For brevity, these details are not repeated here. 
       FIGS.  8 A- 8 F  illustrate a flow diagram of a method  800  of providing tactile outputs based on one or more regions of a user interface, in accordance with some embodiments. The method  800  is performed at an electronic device (e.g., device  300 ,  FIG.  3   , or portable multifunction device  100 ,  FIG.  1 A ) with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method  800  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, the method  800  provides an intuitive way to provide tactile outputs based on one or more regions of a user interface. The method reduces the cognitive burden on a user when providing tactile outputs based on one or more regions of a user interface, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to provide tactile outputs based on one or more regions of a user interface faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays ( 802 ), on the display of the electronic device, a user interface that includes a first region that is configured to initiate a first display operation in response to an input (e.g., a light press) (optionally, an input associated with the first region) that satisfies first activation criteria and initiate a second display operation in response to an input (e.g., a deep press) (optionally, an input associated with the first region) that satisfies second activation criteria distinct from the first activation criteria, and a second region that is distinct from the first region, wherein the second region is configured to initiate a third display operation in response to an input (optionally, an input associated with the second region) that satisfies the first activation criteria (e.g., a light press) and the second region is not configured to initiate any display operation in response to an input (optionally, an input associated with the second region) that satisfies the second activation criteria (e.g., a deep press). For example, the first region is responsive to inputs that satisfy one or more first activation criteria and is also responsive to inputs that satisfy one or more second activation criteria, and the second region is responsive to inputs that satisfy the first activation criteria and is not responsive to inputs that satisfy the second activation criteria. 
     In some embodiments, the first activation criteria include ( 804 ) first intensity criteria. In some embodiments, the first intensity criteria include a first intensity threshold. In some embodiments, the second activation criteria include ( 806 ) second intensity criteria distinct from the first intensity criteria. In some embodiments, the second intensity criteria include a second intensity threshold that is higher than the first intensity threshold. 
     In some embodiments, the first region is ( 808 ) a region that includes a user interface control and the second region is a region that does not include any user interface control. In some embodiments, the user interface includes ( 810 ) a plurality of regions that are configured to perform display operations in response to inputs that satisfy the second activation criteria, and (all other) regions of the user interface that are outside of the plurality of regions are not configured to perform display operations to inputs that satisfy the second activation criteria. In some embodiments, the second activation criteria are correspond to a unique form of input to which only certain controls and/or applications are configured to respond. However, in order to maintain a consistent feel for the user interface, the input device provides feedback to the user indicating that the second activation criteria have been met even when the input corresponds to a location outside of the controls or applications that are configured to respond to the second activation criteria. 
     While displaying the user interface of the first software application, the device performs at least the following operations. The device detects ( 812 ) a first input that includes a contact detected on the touch-sensitive surface, wherein the contact included in the first input is associated with the first region of the user interface. 
     In response to detecting the first input, and in accordance with a determination that the first input satisfies the first activation criteria (e.g., a light press), the device performs ( 814 ) the first display operation. In some embodiments, in response to detecting the first input, in accordance with the determination that the first input satisfies the first activation criteria (e.g., a light press), the device concurrently generates ( 816 ) a tactile output of a third type that is distinct from the tactile output of the first type while performing the first display operation. For example, as illustrated in Figure SEE, region chart  5070  indicates that a detected contact is associated with the first region. In response to detecting the input associated with contact  5062 , having an intensity level above threshold IT L , and below threshold IT D , the “Users” folder (object  5004 - 6 ) is highlighted (an exemplary first display operation is performed). Figure SEE also illustrates performance of this operation in conjunction with generating a third tactile output. 
     In some embodiments, the tactile output of the third type is distinct from the tactile output of a second type, described below. In some embodiments, the tactile output of the third type (e.g., a tactile output indicating a light press) has less salience ( 818 ) than salience of the tactile output of the first type (e.g., a tactile output for a deep operation) and greater salience than salience of the tactile output of a second type (e.g., a tactile output indicating absence of a deep operation). In some embodiments, the salience of a tactile output includes one or more of: an amplitude of the tactile output (e.g., speed and force of a displacement of the touch-sensitive surface) and a duration of the tactile output. 
     In response to detecting the first input, and in accordance with a determination that the first input satisfies the second activation criteria (e.g., a deep press), the device performs ( 820 ) the second display operation and concurrently generating a tactile output of a first type (e.g., a tactile output for a deep operation) while performing the second display operation. For example, as illustrated in  FIG.  5 FF , region chart  5070  indicates that a detected contact is associated with the first region. In response to detecting the input associated with contact  5062 , having an intensity level above threshold IT D , a menu associated with the “Users” folder (object  5004 - 6 ) is displayed (an exemplary second display operation is performed).  FIG.  5 FF  also illustrates performance of this operation in conjunction with generating a first tactile output.  FIG.  5 FF  also illustrates performance of this operation without performing the first display operation (e.g., highlighting the “Users” folder). 
     The device detects ( 822 ) a second input that includes a contact detected on the touch-sensitive surface, wherein the second input is distinct from the first input and the contact included in the second input is associated with the second region of the user interface. For example,  FIG.  5 GG  illustrates a second input including contact  5074 , associated with the file view control object  5008 - 1 , and region chart  5070  indicates that the detected contact is associated with the second region. 
     In response to detecting the second input, and in accordance with a determination that the second input satisfies the first activation criteria (e.g., a light press), the device performs ( 824 ) the third display operation. In some embodiments, in response to detecting the second input and in accordance with the determination that the second input satisfies the first activation criteria (e.g., a light press), the device concurrently generates ( 826 ) a tactile output of a fourth type that is distinct from the tactile output of the third type while performing the third display operation. For example, as illustrated in  FIG.  5 HH , region chart  5070  indicates that a detected contact is associated with the second region. In response to detecting the input associated with contact  5074 , having an intensity level above threshold IT L , and below threshold IT D , the file view control icon  5008 - 1  is selected and region  5054  displays the contents of the “Macintosh HD” directory in an icon-view.  FIG.  5 HH  also illustrates performance of this operation in conjunction with generating a tactile output of a fourth type. In some embodiments, in response to detecting the second input and in accordance with the determination that the second input satisfies the first activation criteria (e.g., a light press), the device concurrently generates ( 828 ) a tactile output of the third type while performing the third display operation. 
     In response to detecting the second input, and in accordance with a determination that the second input satisfies the second activation criteria (e.g., a deep press), the device generates ( 830 ) a tactile output of a second type (e.g., a tactile output indicating absence of a deep operation). In some embodiments, the tactile output of the second type is distinct ( 832 ) from the tactile output of the first type. In some embodiments, the tactile output of the second type is identical to the tactile output of the first type. 
     In some embodiments, in response to detecting the second input and in accordance with the determination that the second input satisfies the second activation criteria (e.g., a deep press), the device forgoes ( 834 ) performing the first display operation, the second display operation, and the third display operation. For example, as illustrated in  FIG.  5 II , region chart  5070  indicates that a detected contact is associated with the second region. In response to detecting the input associated with contact  5074 , having an intensity level above threshold IT D , there is no display operation performed (e.g., there is no change in the display of the contents of display  450 , from  FIG.  5 HH ).  FIG.  5 II  also illustrates forgoing performance of any display operation in conjunction with generating a tactile output of the second type. For example, in  FIG.  5 II , the tactile output of the second type indicates to the user of the device that there is no display operation associated with a “deep press” detected while the cursor is over the icon file control object. 
     In some embodiments, the tactile output of the second type (e.g., a tactile output indicating absence of a deep operation) has less salience ( 836 ) than salience of the tactile output of the first type (e.g., a tactile output for a deep operation). 
     In some embodiments, the user interface includes ( 838 ) a third region that is not configured to initiate any display operation in response to an input (associated with the third region) that satisfies first activation criteria and is not configured to initiate any display operation in response to an input (associated with the third region) that satisfies second activation criteria distinct from the first activation criteria (e.g., the third region is not responsive to inputs that satisfy the first activation criteria or the second activation criteria). Furthermore, in some embodiments, the device detects ( 840 ) a third input that includes a contact detected on the touch-sensitive surface, wherein the contact included in the first input is associated with the third region of the user interface. 
     In some embodiments, in response to detecting the third input, and in accordance with a determination that the third input satisfies the first activation criteria (e.g., a light press), the device generates ( 842 ) a tactile output of the third type (e.g., a tactile output indicating a light press). For example, as illustrated in  FIG.  5 JJ , region chart  5070  indicates that a detected contact is associated with the third region. In response to detecting the input associated with contact  5078 , having an intensity level above threshold IT L  and below IT D , there is no display operation performed.  FIG.  5 JJ  also illustrates forgoing performance of any display operation in conjunction with generating a tactile output of the third type. For example, in  FIG.  5 JJ , the tactile output of the second type indicates to the user of the device that there is no display operation associated with a “light press” detected while the cursor is over control object  5008 - 4 . 
     In some embodiments, in response to detecting the third input, and in accordance with a determination that the third input satisfies the second activation criteria (e.g., a deep press), the device generates ( 844 ) a tactile output of the second type (e.g., a tactile output indicating absence of a deep operation). For example, as illustrated in  FIG.  5 KK , region chart  5070  indicates that a detected contact is associated with the third region. In response to detecting the input associated with contact  5078 , having an intensity level above threshold IT D , there is no display operation performed.  FIG.  5 KK  also illustrates forgoing performance of any display operation in conjunction with generating a tactile output of the second type. For example, in  FIG.  5 KK , the tactile output of the second type indicates to the user of the device that there is no display operation associated with a “deep press” detected while the cursor is over the control object  5008 - 4 . 
     Thus, in some embodiments, the tactile output associated with a light press input is the same everywhere, while a tactile output associated with a deep press input is different depending on whether the portion of the user interface corresponding to the deep press input is configured to respond to the deep press input (e.g., so as to provide the user with an indication of which user interface elements are responsive to a deep press input and which user interface elements are not responsive to the deep press input). 
     In some embodiments, the device detects ( 846 ) an occurrence of a predefined event associated with the second region while the second region is not configured to initiate any display operation in response to an input (associated with the second region) that satisfies the second activation criteria (e.g., a deep press). In some embodiments, in response to detecting the occurrence of the predefined event, the device configures ( 848 ) the second region to initiate a fourth display operation in response to an input that satisfies the second activation criteria. 
     In some embodiments, while the second region is configured to initiate the fourth display operation in response to an input that satisfies the second activation criteria, the device detects ( 850 ) a fourth input that includes a contact detected on the touch-sensitive surface, wherein the contact included in the third input is associated with the second region of the user interface. In some embodiments, in response to detecting the fourth input, and in accordance with a determination that the fourth input satisfies the third activation criteria (e.g., a light press), the device performs ( 852 ) the third display operation. In some embodiments, in response to detecting the fourth input, and in accordance with a determination that the fourth input satisfies the second activation criteria (e.g., a deep press), the device performs ( 854 ) the fourth display operation and concurrently generates a tactile output of the first type (e.g., a tactile output for a deep operation) while performing the second display operation. 
     In some embodiments, in response to detecting the first input and in accordance with a determination that the first input does not satisfy the first activation criteria and does not satisfy the second activation criteria, the device forgoes ( 856 ) generating any tactile output, and in response to detecting the second input, in accordance with a determination that the second input does not satisfy the first activation criteria and does not satisfy the second activation criteria, the device forgoes ( 858 ) generating any tactile output. 
     In some embodiments, the user interface is generated ( 860 ) by a first application running on the device (e.g., a user facing application such as the user interface generating portion of an operating system, a file browser, a web browser, a mail application, etc.) and the determination as to whether to provide the first tactile output or the second tactile output when the second set of activation criteria are satisfied is made by a second application running on the device (e.g., firmware that controls a tactile output mechanism) that is distinct from the first application. 
     It should be understood that the particular order in which the operations in  FIGS.  8 A- 8 F  have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., methods  600 ,  700 , and  900 ) are also applicable in an analogous manner to method  800  described above with respect to  FIGS.  8 A- 8 F . For example, the contacts, inputs, operations, activation criteria, salience, intensity thresholds, regions, tactile output types, and tactile outputs described above with reference to method  700  optionally have one or more of the characteristics of the contacts, inputs, operations, activation criteria, salience, intensity thresholds, regions, tactile output types, and tactile outputs described herein with reference to other methods described herein (e.g., methods  600 ,  700 , and  900 ). For brevity, these details are not repeated here. 
       FIGS.  9 A- 9 C  illustrate a flow diagram of a method  900  of configuring tactile outputs and activation criteria, in accordance with some embodiments. The method  900  is performed at an electronic device (e.g., device  300 ,  FIG.  3   , or portable multifunction device  100 ,  FIG.  1 A ) with a display, a touch-sensitive surface, one or more sensors to detect intensity of contacts with the touch-sensitive surface, and one or more tactile output generators. In some embodiments, the display is a touch-screen display and the touch-sensitive surface is on or integrated with the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method  900  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, the method  900  provides an intuitive way to configure tactile outputs and activation criteria. The method reduces the number, extent, and/or nature of the inputs from a user when configuring tactile outputs and activation criteria, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to configure tactile outputs and activation criteria faster and more efficiently conserves power and increases the time between battery charges. 
     The device is configured to provide ( 902 ) a first tactile output (e.g., a light press tactile output) in response to detecting that first activation criteria have been met (e.g., light press activation criteria), the first activation criteria including a criterion that is met when an intensity of a contact on the touch-sensitive surface increases above a first intensity threshold (e.g., selection of draggable object  5004 - 6  in response to intensity between IT L  and IT D , as shown in  FIG.  5 CC ). The device is configured to provide ( 904 ) a second tactile output (e.g., a deep press tactile output) in response to detecting that second activation criteria have been met (e.g., deep press activation criteria), the second activation criteria including a criterion that is met when an intensity of a contact on the touch-sensitive surface increases above a second intensity threshold, distinct from the first intensity threshold (e.g., display of menu  5064  in response to intensity above IT D , as shown in  FIG.  5 DD ). 
     The device displays ( 906 ), on the display, a settings user interface (e.g., the user interface illustrated in  FIG.  5 MM  or  FIG.  5 NN ) that includes one or more control objects, wherein the settings user interface is configured to adjust operations of the device that use: the one or more sensors that detect intensity of contacts with the touch-sensitive surface, and/or the one or more tactile output generators. 
     While displaying the settings user interface, the device detects ( 908 ) an input for a first control object of the one or more control objects (e.g., an input for a single, combined contact intensity/tactile output setting control). In some embodiments, the first control object is ( 910 ) a discrete control object that corresponds to a particular setting. For example, a check box that corresponds to a high, medium or low intensity/output setting (e.g., control objects  5088  in  FIG.  5 MM ). In some embodiments, the first control object is ( 912 ) a continuous control object that corresponds to three or more settings. For example, a virtual slider or a virtual dial that corresponds to a range of intensity/output settings, from a high setting to a low setting (e.g., control object  5089  in  FIG.  5 NN ). 
     In accordance with the detected input for the first control object, the device changes ( 914 ) the second intensity threshold (e.g., increasing or decreasing a magnitude of the second intensity threshold), and changes ( 916 ) the second tactile output (e.g., increasing or decreasing a magnitude, duration, frequency, salience, and/or other output characteristic of the second tactile output). In some embodiments, the second intensity threshold and the second tactile output are changed in response to detecting the input for the first control object. In some embodiments, the second intensity threshold and the second tactile output are changed as soon as the input for the first control object is detected. In some embodiments, the second intensity threshold and the second tactile output are changed by activating an “accept changes,” “set,” “exit,” or other similar icon in the settings user interface. 
     In some embodiments, in accordance with the detected input for the first control object, the device changes ( 918 ) the first intensity threshold (e.g., increasing or decreasing a magnitude of the first intensity threshold). In some embodiments, the magnitude of the first intensity threshold is changed in a same way and/or amount as the magnitude of the second intensity threshold (e.g., the first intensity threshold and the second intensity threshold are both increased by 15% or are both decreased by 15%, depending on the change in the setting indicated by the detected user input on the first control object). In some embodiments, the first intensity threshold is changed in response to detecting the input for the first control object. In some embodiments, the first intensity threshold is changed as soon as the input for the first control object is detected. In some embodiments, the first intensity threshold is changed by activating an “accept changes,” “set,” “exit,” or other similar icon in the settings user interface. 
     In some embodiments, in accordance with the detected input for the first control object, the device changes ( 920 ) the first tactile output (e.g., increasing or decreasing a magnitude, duration, frequency, salience, and/or other output characteristic of the first tactile output). In some embodiments, the characteristics of the first tactile output are changed in a same way and/or amount as the characteristics of the second tactile output (e.g., the amplitude of the first tactile output and the second tactile output are both increased by 15% or are both decreased by 15%, depending on the change in the setting indicated by the detected user input on the first control object). In some embodiments, the first tactile output is changed in response to detecting the input for the first control object. In some embodiments, the first tactile output is changed as soon as the input for the first control object is detected. In some embodiments, the first tactile output is changed by activating an “accept changes,” “set,” “exit,” or other similar icon in the settings user interface. 
     In some embodiments, in addition to the first tactile output and the second tactile output, the device is configured to provide other tactile outputs in response to detecting events associated with movement of a contact on the touch-sensitive surface (e.g., providing tactile output “detents” in response to detecting movement on the touch-sensitive surface that corresponds to movement of a cursor on the display along a slider or over a boundary in a displayed user interface). Furthermore, in accordance with the detected input for the first control object, the device changes ( 922 ) the other tactile outputs (e.g., increasing or decreasing a magnitude, duration, frequency, salience, and/or other output characteristic of the other tactile outputs that the device is configured to provide). In some embodiments, the characteristics of the first tactile output, the second tactile output and the other tactile outputs are all changed in the same manner (e.g., all are increased in amplitude by 15% or all are decreased in amplitude by 15%, depending on the setting selected by the user with the input on the first control object). In some embodiments, the other tactile outputs are changed in response to detecting the input for the first control object. In some embodiments, the other tactile outputs are changed as soon as the input for the first control object is detected. In some embodiments, the other tactile outputs are by activating an “accept changes,” “set,” “exit,” or other similar icon in the settings user interface. 
     In some embodiments, the first intensity threshold is lower than the second intensity threshold. Thus, in some embodiments, the intensity of a new contact detected on the touch-sensitive surface will have to pass through the first intensity threshold to reach the second intensity threshold. Furthermore, the second activation criteria includes a time-based criterion that is dependent upon a time at which the first activation criteria is met, and in accordance with the detected input for the first control object, the device changes ( 924 ) the time-based criterion. In some embodiments, the device increases the length of a delay time period (e.g., the delay time between the time when the first activation criteria are met and the time when the second intensity threshold is met). In some embodiments, the device decreases the length of a delay time. In some embodiments, when the second intensity threshold is increased, a delay time in the time-based criterion is lengthened, and the duration, amplitude, and/or salience of the second tactile output are increased. In some embodiments, when the second intensity threshold is decreased, a delay time in the time-based criterion is shortened, and the duration, amplitude, and/or salience of the second tactile output are decreased. In some embodiments, the device has a reduced-sensitivity time period after the first activation criteria are met, during which the second intensity threshold is temporarily increased, and this reduced-sensitivity time period is increased or decreased in accordance with the detected input for the first control object. In some embodiments, the time-based criterion is changed in response to detecting the input for the first control object. In some embodiments, the time-based criterion is changed as soon as the input for the first control object is detected. In some embodiments, the time-based criterion is changed by activating an “accept changes,” “set,” “exit,” or other similar icon in the settings user interface. 
     In some embodiments, the time-based criterion includes a delay time period that occurs after the time at which the first activation criteria were met, and the time-based criterion is met ( 926 ) after the delay time period has elapsed. In some embodiments, the time-based criterion is met upon completion of the delay time period. For example, during the delay time period, the second activation criteria are not met, even if an intensity of the contact is above the second intensity threshold, to prevent accidental activation of the second tactile output. 
     In some embodiments, the second activation criteria include ( 928 ) a criterion that is met when the intensity of the contact increases by more than a predefined amount (e.g., and/or increases above the second intensity threshold) after the delay time period has elapsed. For example, in order to meet the second activation criteria, after the delay time period, the user has to increase the intensity of the contact by pressing harder. 
     In some embodiments, the second activation criteria include ( 930 ) a criterion that is met when the intensity of the contact increases from an intensity below the second intensity threshold to an intensity above the second intensity threshold after the delay time period has elapsed. For example, in order to meet the second activation criteria, if the contact intensity is already above the second intensity threshold at the end of the delay time period, the user has to back off and press again by reducing the intensity of their contact below the second intensity threshold and then increasing the intensity of their contact above the second intensity threshold. 
     In some embodiments, the time-based criterion includes ( 936 ,  FIG.  9 C ) one or more of: a first offset that decreases over time (e.g., the decaying intensity threshold offset illustrated in the left intensity diagram in  FIG.  5 PP ); and a second offset that changes over time based on an intensity of a contact on the touch-sensitive surface (e.g., the trailing force intensity threshold offset illustrated in the center intensity diagram in  FIG.  5 PP ). In some embodiments, the first offset decreases over time from the time at which the first activation criteria are satisfied. In some embodiments, the first offset decreases over time after a predefined duration from the time at which the first activation criteria are satisfied. 
     In some embodiments, the time-based criterion includes ( 938 ) an intensity offset for a user that is determined based on multiple separate inputs (e.g., inputs that are not continuous extensions of one another) on the touch-sensitive surface by the user. For example, as explained above with respect to  FIG.  5 QQ , for a user who has a tendency to provide high intensity inputs, an intensity offset for the user is used to increase the deep activation intensity threshold, thereby reducing unintentional activation of a deep press operation. In some embodiments, the intensity offset for the user is determined based on the user&#39;s historical inputs (e.g., prior inputs). In some embodiments, the intensity offset for the user is determined prior to detecting the contact on the touch-sensitive surface that is processed to determine whether to provide the second tactile output. 
     In some embodiments, the intensity offset for the user is determined ( 940 ) based on one or more of: peak intensities of a first predefined number of separate click inputs on the touch-sensitive surface by the user (e.g., peak intensities of clicks made by the user), and peak intensities of a second predefined number of separate drag inputs on the touch-sensitive surface by the user (e.g., peak intensities during drag inputs made by the user). For example, peak intensities of the prior 10, 20, 30, 40, 50, 60, 70, 80, or 90 click inputs by the user, and/or peak intensities during the prior 10, 20, 30, 40, 50, 60, 70, 80, or 90 drag inputs by the user are used to determine the intensity offset for the user in some embodiments. In some embodiments, peak intensities of click inputs that satisfy the first intensity threshold and that do not satisfy the second intensity threshold are used for determining the intensity offset for the user (e.g., peak intensities of click inputs that satisfy the second intensity threshold are excluded). In some embodiments, peak intensities of click inputs that remain in contact with the touch-sensitive surface for a duration longer than a predefined duration threshold (e.g., 0.1 s, 0.2 s, 0.3 s, 0.4 s, 0.5 s, 0.6 s, 0.7 s, 0.8 s, 0.9 s, 1 s, 2 s, 3 s, 4 s, 5 s, etc.) are excluded from determining the intensity offset for the user. In some embodiments, the first predefined number is the same as the second predefined number. In some embodiments, the first predefined number is distinct from the second predefined number. 
     In some embodiments, the peak intensities of prior click inputs by the user are compared to a reference intensity of a click input (e.g., an average or median intensity of click inputs made by multiple users) to determine the intensity offset for the user. In some embodiments, the peak intensities of prior drag inputs by the user are compared to a reference intensity of a drag input (e.g., an average or median intensity of drag inputs made by multiple users) to determine the intensity offset for the user. In some embodiments, the reference intensity of a click input and/or the reference intensity of a drag input are/is adjusted based on the user input on the settings user interface. For example, when a low deep press intensity is selected (e.g., from the settings user interface illustrated in  FIG.  5 MM ), a reference intensity of a low intensity click input and/or a reference intensity of a low intensity drag input are used. Similarly, when a high deep press intensity is selected, a reference intensity of a high intensity click input and/or a reference intensity of a high intensity drag input are used. 
     In some embodiments, the time-based criterion includes ( 932 ,  FIG.  9 B ) a reduced-sensitivity time period that occurs after the time at which the first activation criteria are satisfied, and during the reduced-sensitivity time period, the second intensity threshold is increased. For example, during the reduced-sensitivity period, the second intensity threshold is temporarily increased to prevent accidental activation of the second tactile output. 
     In some embodiments, the device is configured ( 934 ) to respond to the satisfaction of the first activation criteria with a first type of operation (e.g., a light/primary activation), and the device is configured to respond to the satisfaction of the second activation criteria with a second type of operation (e.g., a deep/alternative activation) that is different from the first type of operation. 
     In some embodiments, while displaying a first user interface and while the device is in a first haptic output mode of a plurality of haptic output modes, the device provides a first haptic output (e.g., a light press haptic output) in response to detecting that first activation criteria (e.g., light press activation criteria) for the first haptic output mode have been met, the first activation criteria for the first haptic output mode including a criterion that is met when an intensity of a contact on the touch-sensitive surface increases above a first intensity threshold. In some embodiments, the device also provides a second haptic output (e.g., a deep press haptic output) in response to detecting that second activation criteria (e.g., deep press activation criteria) for the first haptic output mode have been met, the second activation criteria for the first haptic output mode including a criterion that is met when an intensity of a contact on the touch-sensitive surface increases above a second intensity threshold. 
     In some embodiments, the device displays a settings user interface for controlling operation of the touch-sensitive surface, the settings user interface including a plurality of control objects, and while displaying the settings user interface, the device detects an input associated with a control object of the plurality of control objects in the settings user interface (e.g., an intensity/output setting control). 
     In some embodiments, in response to detecting the input associated with the single control in the settings user interface, the device exits the first haptic output mode and enters a second haptic output mode, of the plurality of haptic output modes, that is distinct from the first haptic output mode, and while displaying a second user interface and while the device is in the second haptic output mode, the device provides a third haptic output (e.g., a deep press haptic output) in response to detecting that second activation criteria (e.g., deep press activation criteria) for the second haptic output mode have been met, the second activation criteria for the second haptic output mode including a criterion that is met when an intensity of a contact on the touch-sensitive surface increases above a third intensity threshold, wherein the third intensity threshold is distinct from the second intensity threshold, and a salience (e.g., magnitude, duration, frequency) of the third haptic output is distinct from the second haptic output.

It is understood by persons of skill in the art that the functional blocks described in  FIG.  11    are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments.

In some embodiments, the contact in the second input satisfies a first intensity threshold (e.g., using intensity determination unit  1122 ) and the contact in the third input satisfies a second intensity threshold that is higher than the first intensity threshold. In some embodiments, the processing unit  1108  is further configured to, in response to detecting the second input (e.g., with input detection unit  1112 ), in accordance with the determination that the first tactile output setting is active for the second input (e.g., with tactile output setting determination unit  1120 ), perform the second operation without performing the first operation (e.g., operation performance unit  1118 ). 
     In some embodiments, the processing unit  1108  is further configured to, in response to detecting the second input (e.g., with input detection unit  1112 ), in accordance with the determination that the first tactile output setting is active (e.g., with tactile output setting determination unit  1120 ) for the second input, forgo generation of the first tactile output.

     The operations described above with reference to  FIGS.  7 A- 7 D  are, optionally, implemented by components depicted in  FIGS.  1 A- 1 B  or  FIG.  11   . For example, input-detection operation  704 , and tactile output generation operation  712  are, optionally, implemented by event sorter  170 , event recognizer  180 , and event handler  190 . Event monitor  171  in event sorter  170  detects a contact on touch-sensitive display  112 , and event dispatcher module  174  delivers the event information to application  136 - 1 . A respective event recognizer  180  of application  136 - 1  compares the event information to respective event definitions  186 , and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer  180  activates an event handler  190  associated with the detection of the event or sub-event. Event handler  190  optionally uses or calls data updater  176  or object updater  177  to update the application internal state  192 . In some embodiments, event handler  190  accesses a respective GUI updater  178  to update what is displayed by the application.

     In some embodiments, the user interface includes a third region that is not configured to initiate any display operation in response to an input that satisfies first activation criteria and is not configured to initiate any display operation in response to an input that satisfies second activation criteria distinct from the first activation criteria, and the processing unit  1208  is further configured to: detect a third input (e.g., with the input detection unit  1212 ) that includes a contact detected on the touch-sensitive surface unit  1204 , wherein the contact included in the first input is associated with the third region of the user interface, and in response to detecting the third input, in accordance with a determination that the third input satisfies the first activation criteria (e.g., with the activation criteria determination unit  1220 ), generate a tactile output of the third type (e.g., with the tactile output generation unit  1214 ), and in accordance with a determination that the third input satisfies the second activation criteria (e.g., with the activation criteria determination unit  1220 ), generate a tactile output of the second type (e.g., with the tactile output generation unit  1214 ). 
     In some embodiments, the tactile output of the second type has less salience than salience of the tactile output of the first type. In some embodiments, the tactile output of the third type has less salience than salience of the tactile output of the first type and greater salience than salience of the tactile output of the second type. In some embodiments, the first activation criteria include first intensity criteria. In some embodiments, the second activation criteria include second intensity criteria distinct from the first intensity criteria. In some embodiments, the first region is a region that includes a user interface control and the second region is a region that does not include any user interface control. 
     In some embodiments, the processing unit  1208  is further configured to: in response to detecting the first input (e.g., with the input detection unit  1212 ), in accordance with a determination that the first input does not satisfy the first activation criteria and does not satisfy the second activation criteria (e.g., with the activation criteria determination unit  1220 ), forgo generating any tactile output, and in response to detecting the second input (e.g., with the input detection unit  1212 ), in accordance with a determination that the second input does not satisfy the first activation criteria and does not satisfy the second activation criteria (e.g., with the activation criteria determination unit  1220 ), forgo generating any tactile output. 
     In some embodiments, the processing unit  1208  is further configured to: detect an occurrence of a predefined event associated with the second region while the second region is not configured to initiate any display operation in response to an input that satisfies the second activation criteria, in response to detecting the occurrence of the predefined event, configure the second region to initiate a fourth display operation in response to an input that satisfies the second activation criteria.

     In some embodiments, the user interface includes a plurality of regions that are configured to perform display operations in response to inputs that satisfy the second activation criteria, and regions of the user interface that are outside of the plurality of regions are not configured to perform display operations to inputs that satisfy the second activation criteria. In some embodiments, the user interface is generated by a first application running on the device and the determination as to whether to provide the first tactile output or the second tactile output when the second set of activation criteria are satisfied is made by a second application running on the device that is distinct from the first application. 
     The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to  FIGS.  1 A and  3   ) or application specific chips. 
     The operations described above with reference to  FIGS.  8 A- 8 F  are, optionally, implemented by components depicted in  FIGS.  1 A- 1 B  or  FIG.  12   . For example, input-detection operation  812 , and tactile output generation operation  820  are, optionally, implemented by event sorter  170 , event recognizer  180 , and event handler  190 . Event monitor  171  in event sorter  170  detects a contact on touch-sensitive display  112 , and event dispatcher module  174  delivers the event information to application  136 - 1 . A respective event recognizer  180  of application  136 - 1  compares the event information to respective event definitions  186 , and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer  180  activates an event handler  190  associated with the detection of the event or sub-event. Event handler  190  optionally uses or calls data updater  176  or object updater  177  to update the application internal state  192 . In some embodiments, event handler  190  accesses a respective GUI updater  178  to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in  FIGS.  1 A- 1 B .

The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in  FIG.  13    are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein. 
     As shown in  FIG.  13   , an electronic device  1300  includes a display unit  1302  configured to display a user interface, a touch-sensitive surface unit  1304  configured to receive contacts, one or more sensor units  1306  configured to detect intensity of contacts with the touch-sensitive surface unit  1304 ; one or more tactile output units  1332  configured to provide tactile outputs; and a processing unit  1308  coupled with the display unit  1302 , the touch-sensitive surface unit  1304  the one or more sensor units  1306  and the one or more tactile output units  1332 .

     The one or more tactile output units  1332  are configured to: provide a first tactile output in response to detecting that first activation criteria have been met, the first activation criteria including a criterion that is met when an intensity of a contact on the touch-sensitive surface unit  1304  increases above a first intensity threshold and provide a second tactile output in response to detecting that second activation criteria have been met, the second activation criteria including a criterion that is met when an intensity of a contact on the touch-sensitive surface unit  1304  increases above a second intensity threshold, distinct from the first intensity threshold. 
     In some embodiments, the processing unit  1308  is configured to: provide a first tactile output (e.g., with the tactile output generation unit  1314 ) in response to detecting that first activation criteria have been met (e.g., with activation criteria determination unit  1320 ), the first activation criteria including a criterion that is met when an intensity of a contact on the touch-sensitive surface unit  1304  increases above a first intensity threshold (e.g., using intensity determination unit  1322 ) and provide a second tactile output (e.g., with the tactile output generation unit  1314 ) in response to detecting that second activation criteria have been met (e.g., with activation criteria determination unit  1320 ), the second activation criteria including a criterion that is met when an intensity of a contact on the touch-sensitive surface unit  1304  increases above a second intensity threshold, distinct from the first intensity threshold (e.g., using intensity determination unit  1322 ). 
     The processing unit  1308  is also configured to: enable display (e.g., with display enablement unit  1308 ) of a settings user interface that includes one or more control objects, wherein the settings user interface is configured to adjust operations of the device that use: the one or more sensors that detect intensity of contacts (e.g., one or more sensor units  1306 ) with the touch-sensitive surface unit  1304 , and/or the one or more tactile output generators (e.g., one or more tactile output units  1332 ). The processing unit  1308  is configured to, while enabling display of the settings user interface: detect an input (e.g., with input detection unit  1312 ) for a first control object of the one or more control objects, and in accordance with the detected input for the first control object, change the second intensity threshold (e.g., with intensity threshold changing unit  1324 ) and change the second tactile output (e.g., with tactile output changing unit  1326 ). 
     In some embodiments, the processing unit  1308  is further configured to: in accordance with the detected input for the first control object, change the first intensity threshold (e.g., with intensity threshold changing unit  1324 ). In some embodiments, the processing unit  1308  is further configured to: in accordance with the detected input for the first control object, change the first tactile output (e.g., with tactile output changing unit  1326 ). 
     In some embodiments, the processing unit  1308  is further configured to: provide other tactile outputs (e.g., with tactile output generation unit  1314 ) in response to detecting events associated with movement of a contact (e.g., with contact movement detection unit  1316 ) on the touch-sensitive surface unit  1304 , and in accordance with the detected input for the first control object, change the other tactile outputs (e.g., with tactile output changing unit  1326 ). 
     In some embodiments, the first intensity threshold is lower than the second intensity threshold, the second activation criteria includes a time-based criterion that is dependent upon a time at which the first activation criteria is met, and the processing unit  1308  is further configured to: in accordance with the detected input for the first control object, change the time-based criterion (e.g., with time-based criterion changing unit  1328 ). In some embodiments, the time-based criterion includes a delay time period that occurs after the time at which the first activation criteria were met, and the time-based criterion is met after the delay time period has elapsed. 
     In some embodiments, the second activation criteria include a criterion that is met (e.g., using activation criteria determination unit  1320 ) when the intensity of the contact increases by more than a predefined amount after the delay time period has elapsed. In some embodiments, the second activation criteria include a criterion that is met (e.g., using activation criteria determination unit  1320 ) when the intensity of the contact increases from an intensity below the second intensity threshold to an intensity above the second intensity threshold (e.g., using intensity determination unit  1322 ) after the delay time period has elapsed. 
     In some embodiments, the time-based criterion includes a reduced-sensitivity time period that occurs after the time at which the first activation criteria are satisfied, and during the reduced-sensitivity time period, the second intensity threshold is increased. In some embodiments, the device is configured to respond to the satisfaction of the first activation criteria with a first type of operation (e.g., with operation performance unit  1318 ), and the device is configured to respond to the satisfaction of the second activation criteria with a second type of operation (e.g., with operation performance unit  1318 ) that is different from the first type of operation. 
     In some embodiments, the time-based criterion includes one or more of: a first offset that decreases over time; and a second offset that changes over time based on an intensity of a contact on the touch-sensitive surface unit  1304 . 
     In some embodiments, the time-based criterion includes an intensity offset for a user that is determined based on multiple separate inputs on the touch-sensitive surface unit  1304  by the user. 
     In some embodiments, the intensity offset for the user is determined based on one or more of: peak intensities of a first predefined number of separate click inputs on the touch-sensitive surface unit  1304  by the user, and peak intensities of a second predefined number of separate drag inputs on the touch-sensitive surface unit  1304  by the user. 
     In some embodiments, the first control object is a discrete control object that corresponds to a particular setting and in some embodiments, the first control object is a continuous control object that corresponds to three or more settings. 
     The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to  FIGS.  1 A and  3   ) or application specific chips. 
     The operations described above with reference to  FIGS.  9 A- 9 C  are, optionally, implemented by components depicted in  FIGS.  1 A- 1 B  or  FIG.  13   . For example, intensity-threshold changing operation  914 , and tactile output changing operation  920  are, optionally, implemented by event sorter  170 , event recognizer  180 , and event handler  190 . Event monitor  171  in event sorter  170  detects a contact on touch-sensitive display  112 , and event dispatcher module  174  delivers the event information to application  136 - 1 . A respective event recognizer  180  of application  136 - 1  compares the event information to respective event definitions  186 , and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer  180  activates an event handler  190  associated with the detection of the event or sub-event. Event handler  190  optionally uses or calls data updater  176  or object updater  177  to update the application internal state  192 . In some embodiments, event handler  190  accesses a respective GUI updater  178  to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in  FIGS.  1 A- 1 B .
