     DESCRIPTION OF EMBODIMENTS 
     The following description sets forth exemplary methods, parameters, and the like. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure but is instead provided as a description of exemplary embodiments. 
     There is a need for electronic devices that provide efficient methods and interfaces for providing compass application features. For example, a user would benefit from being able to precisely set a bearing in a compass application that is displayed on a small display. As another example, a user would benefit from being able to set a bearing that is resistant to or unaffected by accidental user inputs on the display. Such techniques can reduce the cognitive burden on a user who uses compass application features, thereby enhancing productivity. Further, such techniques can reduce processor and battery power otherwise wasted on redundant user inputs. 
     Below,  FIGS. 1A-1B, 2, 3, 4A-4B, and 5A-5H  provide a description of exemplary devices for performing the techniques for managing event notifications.  FIGS. 6A-6X  illustrate exemplary user interfaces for a compass application in accordance with some embodiments.  FIG. 7  is a flow diagram illustrating an exemplary process for a compass application in accordance with some embodiments. The user interfaces in  FIGS. 6A-6X  are used to illustrate the processes described below, including the processes in  FIG. 7 . 
     Although the following description uses terms “first,” “second,” etc. to describe various elements, these elements should not be limited by the terms. These terms are only used to distinguish one element from another. For example, a first touch could be termed a second touch, and, similarly, a second touch could be termed a first touch, without departing from the scope of the various described embodiments. The first touch and the second touch are both touches, but they are not the same touch. 
     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. 
     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, Calif. 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 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. 1A  is a block diagram illustrating portable multifunction device  100  with touch-sensitive display system  112  in accordance with some embodiments. Touch-sensitive display  112  is sometimes called a “touch screen” for convenience and is sometimes known as or called a “touch-sensitive display system.” 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 control devices  116 , and external port  124 . Device  100  optionally includes one or more optical sensors  164 . Device  100  optionally includes one or more contact 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 “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) 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) 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 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). 
     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. 1A  are implemented in hardware, software, or a combination of both hardware and software, 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. Memory controller  122  optionally controls access to memory  102  by other components of device  100 . 
     Peripherals interface  118  can be used to couple input and output peripherals of the device to CPU  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  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. RF circuitry  108  optionally includes well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. RF circuitry  108  optionally communicates with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication. The RF circuitry  108  optionally includes well-known circuitry for detecting near field communication (NFC) fields, such as by a short-range communication radio. 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 (HSUPA), 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, Bluetooth Low Energy (BTLE), Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, and/or IEEE 802.11ac), 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 screen  112  and other input control devices  116 , to peripherals interface  118 . I/O subsystem  106  optionally includes display controller  156 , optical sensor controller  158 , depth camera controller  169 , 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 control devices  116 . The other input 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 to any (or none) of the following: a keyboard, an infrared port, a USB port, and 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 ). 
     A quick press of the push button optionally disengages a lock of touch screen  112  or optionally begins a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, U.S. Pat. No. 7,657,849, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g.,  206 ) optionally turns power to device  100  on or off. The functionality of one or more of the buttons are, optionally, user-customizable. Touch screen  112  is used to implement virtual or soft buttons and one or more soft keyboards. 
     Touch-sensitive display  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 screen  112 . Touch screen  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 optionally corresponds to user-interface objects. 
     Touch screen  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 screen  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 screen  112  and convert 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 screen  112 . In an exemplary embodiment, a point of contact between touch screen  112  and the user corresponds to a finger of the user. 
     Touch screen  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 screen  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 screen  112 . In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone® and iPod Touch® from Apple Inc. of Cupertino, Calif. 
     A touch-sensitive display in some embodiments of touch screen  112  is, optionally, analogous to the multi-touch sensitive touchpads described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, touch screen  112  displays visual output from device  100 , whereas touch-sensitive touchpads do not provide visual output. 
     A touch-sensitive display in some embodiments of touch screen  112  is described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser. No. 11/038,590, “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed Jan. 18, 2005; (6) U.S. patent application Ser. No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety. 
     Touch screen  112  optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user optionally makes contact with touch screen  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 primarily 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 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 screen  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. 1A  shows an optical sensor coupled to optical sensor controller  158  in I/O subsystem  106 . Optical sensor  164  optionally includes charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor  164  receives light from the environment, projected through one or more lenses, and converts the light to data representing an image. In conjunction with imaging module  143  (also called a camera module), optical sensor  164  optionally captures still images or video. In some embodiments, an optical sensor is located on the back of device  100 , opposite touch screen display  112  on the front of the device so that the touch screen display is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user&#39;s image is, optionally, obtained for video conferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of optical sensor  164  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor  164  is used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     Device  100  optionally also includes one or more depth camera sensors  175 .  FIG. 1A  shows a depth camera sensor coupled to depth camera controller  169  in I/O subsystem  106 . Depth camera sensor  175  receives data from the environment to create a three dimensional model of an object (e.g., a face) within a scene from a viewpoint (e.g., a depth camera sensor). In some embodiments, in conjunction with imaging module  143  (also called a camera module), depth camera sensor  175  is optionally used to determine a depth map of different portions of an image captured by the imaging module  143 . In some embodiments, a depth camera sensor is located on the front of device  100  so that the user&#39;s image with depth information is, optionally, obtained for video conferencing while the user views the other video conference participants on the touch screen display and to capture selfies with depth map data. In some embodiments, the depth camera sensor  175  is located on the back of device, or on the back and the front of the device  100 . In some embodiments, the position of depth camera sensor  175  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a depth camera sensor  175  is used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     Device  100  optionally also includes one or more contact intensity sensors  165 .  FIG. 1A  shows a contact intensity sensor coupled to intensity sensor controller  159  in I/O subsystem  106 . Contact intensity sensor  165  optionally includes 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  165  receives 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  112 , which is located on the front of device  100 . 
     Device  100  optionally also includes one or more proximity sensors  166 .  FIG. 1A  shows proximity sensor  166  coupled to peripherals interface  118 . Alternately, proximity sensor  166  is, optionally, coupled to input controller  160  in I/O subsystem  106 . Proximity sensor  166  optionally performs as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables touch screen  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. 1A  shows a tactile output generator coupled to haptic feedback controller  161  in I/O subsystem  106 . Tactile output generator  167  optionally includes 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). Contact intensity sensor  165  receives 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 screen display  112 , which is located on the front of device  100 .

Furthermore, in some embodiments, memory  102  ( FIG. 1A ) or  370  ( FIG. 3 ) stores device/global internal state  157 , as shown in  FIGS. 1A 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 screen display  112 ; sensor state, including information obtained from the device&#39;s various sensors and input control devices  116 ; and location information concerning the device&#39;s location and/or attitude. 
     Operating system  126  (e.g., Darwin, RTXC, LINUX, UNIX, OS X, iOS, 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 on iPod® (trademark of Apple Inc.) devices. 
     Contact/motion module  130  optionally detects contact with touch screen  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, 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 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. 
     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 threshold 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). 
     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 (liftoff) 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 (liftoff) event. 
     Graphics module  132  includes various known software components for rendering and displaying graphics on touch screen  112  or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including, without limitation, text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations, and the like. 
     In some embodiments, graphics module  132  stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module  132  receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller  156 . 
     Haptic feedback module  133  includes various software components for generating instructions used by tactile output generator(s)  167  to produce tactile outputs at one or more locations on device  100  in response to user interactions with device  100 . 
     Text input module  134 , which is, optionally, a component of graphics module  132 , provides soft keyboards for entering text in various applications (e.g., contacts  137 , e-mail  140 , IM  141 , browser  147 , and any other application that needs text input). 
     GPS module  135  determines the location of the device and provides this information for use in various applications (e.g., to telephone  138  for use in location-based dialing; to camera  143  as picture/video metadata; and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets). 
     Applications  136  optionally include the following modules (or sets of instructions), or a subset or superset thereof:
         Contacts module  137  (sometimes called an address book or contact list);   Telephone module  138 ;   Video conference module  139 ;   E-mail client module  140 ;   Instant messaging (IM) module  141 ;   Workout support module  142 ;   Camera module  143  for still and/or video images;   Image management module  144 ;   Video player module;   Music player module;   Browser module  147 ;   Calendar module  148 ;   Widget modules  149 , which optionally include one or more of: weather widget  149 - 1 , stocks widget  149 - 2 , calculator widget  149 - 3 , alarm clock widget  149 - 4 , dictionary widget  149 - 5 , and other widgets obtained by the user, as well as user-created widgets  149 - 6 ;   Widget creator module  150  for making user-created widgets  149 - 6 ;   Search module  151 ;   Video and music player module  152 , which merges video player module and music player module;   Notes module  153 ;   Map module  154 ; and/or   Online video module  155 .       

     Examples of other applications  136  that are, optionally, stored in memory  102  include other word processing applications, other image editing applications, drawing applications, presentation applications, JAVA-enabled applications, encryption, digital rights management, voice recognition, and voice replication.

No. 11/968,067, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Dec. 31, 2007, the contents of which are hereby incorporated by reference in their entirety. 
     Each of the above-identified modules and applications corresponds 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 (e.g., 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 rearranged in various embodiments. For example, video player module is, optionally, combined with music player module into a single module (e.g., video and music player module  152 ,  FIG. 1A ). 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. 1B  is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory  102  ( FIG. 1A ) 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  137 - 151 ,  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  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  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  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, peripherals 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  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 (e.g., 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  172 , 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  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 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  include 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 liftoff (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second liftoff (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  112 , and liftoff 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  112 , when a touch is detected on touch-sensitive display  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. 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 touchpads; 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  112  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 include 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 touch screen  112 . 
     In some embodiments, device  100  includes touch screen  112 , 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 , headset 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 an alternative embodiment, 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 screen  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 (CPUs)  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. 1A ), 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. 1A ). 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. 1A ), 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. 1A ) optionally does not store these modules. 
     Each of the above-identified elements in  FIG. 3  is, 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 (e.g., 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 rearranged 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 that are, optionally, implemented on, for example, portable multifunction device  100 . 
       FIG. 4A  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 “Maps;”   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, labeled “Settings,” which provides access to settings for device  100  and its various applications  136 .   
               

     It should be noted that the icon labels illustrated in  FIG. 4A  are merely exemplary. For example, 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. 4B  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  (e.g., touch screen display  112 ). Device  300  also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors  359 ) for detecting intensity of contacts on touch-sensitive surface  451  and/or one or more tactile output generators  357  for generating tactile outputs for a user of device  300 . 
     Although some of the examples that follow will be given with reference to inputs on touch screen display  112  (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in  FIG. 4B . In some embodiments, the touch-sensitive surface (e.g.,  451  in  FIG. 4B ) has a primary axis (e.g.,  452  in  FIG. 4B ) that corresponds to a primary axis (e.g.,  453  in  FIG. 4B ) on the display (e.g.,  450 ). In accordance with these embodiments, the device detects contacts (e.g.,  460  and  462  in  FIG. 4B ) with the touch-sensitive surface  451  at locations that correspond to respective locations on the display (e.g., in  FIG. 4B, 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. 4B ) are used by the device to manipulate the user interface on the display (e.g.,  450  in  FIG. 4B ) 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), 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 stylus input). For example, a swipe 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 swipe (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. 
       FIG. 5A  illustrates exemplary personal electronic device  500 . Device  500  includes body  502 . In some embodiments, device  500  can include some or all of the features described with respect to devices  100  and  300  (e.g.,  FIGS. 1A-4B ). In some embodiments, device  500  has touch-sensitive display screen  504 , hereafter touch screen  504 . Alternatively, or in addition to touch screen  504 , device  500  has a display and a touch-sensitive surface. As with devices  100  and  300 , in some embodiments, touch screen  504  (or the touch-sensitive surface) optionally includes one or more intensity sensors for detecting intensity of contacts (e.g., touches) being applied. The one or more intensity sensors of touch screen  504  (or the touch-sensitive surface) can provide output data that represents the intensity of touches. The user interface of device  500  can respond to touches based on their intensity, meaning that touches of different intensities can invoke different user interface operations on device  500 . 
     Exemplary techniques for detecting and processing touch intensity are found, for example, in related applications: International Patent Application Serial No. PCT/US2013/040061, titled “Device, Method, and Graphical User Interface for Displaying User Interface Objects Corresponding to an Application,” filed May 8, 2013, published as WIPO Publication No. WO/2013/169849, and International Patent Application Serial No. PCT/US2013/069483, titled “Device, Method, and Graphical User Interface for Transitioning Between Touch Input to Display Output Relationships,” filed Nov. 11, 2013, published as WIPO Publication No. WO/2014/105276, each of which is hereby incorporated by reference in their entirety. 
     In some embodiments, device  500  has one or more input mechanisms  506  and  508 . Input mechanisms  506  and  508 , if included, can be physical. Examples of physical input mechanisms include push buttons and rotatable mechanisms. In some embodiments, device  500  has one or more attachment mechanisms. Such attachment mechanisms, if included, can permit attachment of device  500  with, for example, hats, eyewear, earrings, necklaces, shirts, jackets, bracelets, watch straps, chains, trousers, belts, shoes, purses, backpacks, and so forth. These attachment mechanisms permit device  500  to be worn by a user. 
       FIG. 5B  depicts exemplary personal electronic device  500 . In some embodiments, device  500  can include some or all of the components described with respect to  FIGS. 1A, 1B , and  3 . Device  500  has bus  512  that operatively couples I/O section  514  with one or more computer processors  516  and memory  518 . I/O section  514  can be connected to display  504 , which can have touch-sensitive component  522  and, optionally, intensity sensor  524  (e.g., contact intensity sensor). In addition, I/O section  514  can be connected with communication unit  530  for receiving application and operating system data, using Wi-Fi, Bluetooth, near field communication (NFC), cellular, and/or other wireless communication techniques. Device  500  can include input mechanisms  506  and/or  508 . Input mechanism  506  is, optionally, a rotatable input device or a depressible and rotatable input device, for example. Input mechanism  508  is, optionally, a button, in some examples. 
     Input mechanism  508  is, optionally, a microphone, in some examples. Personal electronic device  500  optionally includes various sensors, such as GPS sensor  532 , accelerometer  534 , directional sensor  540  (e.g., compass), gyroscope  536 , motion sensor  538 , and/or a combination thereof, all of which can be operatively connected to I/O section  514 . 
     Memory  518  of personal electronic device  500  can include one or more non-transitory computer-readable storage mediums, for storing computer-executable instructions, which, when executed by one or more computer processors  516 , for example, can cause the computer processors to perform the techniques described below, including method  700 . A computer-readable storage medium can be any medium that can tangibly contain or store computer-executable instructions for use by or in connection with the instruction execution system, apparatus, or device. In some examples, the storage medium is a transitory computer-readable storage medium. In some examples, the storage medium is a non-transitory computer-readable storage medium. The non-transitory computer-readable storage medium can include, but is not limited to, magnetic, optical, and/or semiconductor storages. Examples of such storage include magnetic disks, optical discs based on CD, DVD, or Blu-ray technologies, as well as persistent solid-state memory such as flash, solid-state drives, and the like. Personal electronic device  500  is not limited to the components and configuration of  FIG. 5B , but can include other or additional components in multiple configurations. 
     As used here, the term “affordance” refers to a user-interactive graphical user interface object that is, optionally, displayed on the display screen of devices  100 ,  300 , and/or  500  ( FIGS. 1A, 3, and 5A-5B ). For example, an image (e.g., icon), a button, and text (e.g., hyperlink) each optionally constitute an affordance. 
     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. 4B ) 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. 1A  or touch screen  112  in  FIG. 4A ) 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 “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 optionally includes 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 threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective operation or forgo performing the respective operation), rather than being used to determine whether to perform a first operation or a second operation. 
       FIG. 5C  illustrates detecting a plurality of contacts  552 A- 552 E on touch-sensitive display screen  504  with a plurality of intensity sensors  524 A- 524 D.  FIG. 5C  additionally includes intensity diagrams that show the current intensity measurements of the intensity sensors  524 A- 524 D relative to units of intensity. In this example, the intensity measurements of intensity sensors  524 A and  524 D are each 9 units of intensity, and the intensity measurements of intensity sensors  524 B and  524 C are each 7 units of intensity. In some implementations, an aggregate intensity is the sum of the intensity measurements of the plurality of intensity sensors  524 A- 524 D, which in this example is 32 intensity units. In some embodiments, each contact is assigned a respective intensity that is a portion of the aggregate intensity.  FIG. 5D  illustrates assigning the aggregate intensity to contacts  552 A- 552 E based on their distance from the center of force  554 . In this example, each of contacts  552 A,  552 B, and  552 E are assigned an intensity of contact of 8 intensity units of the aggregate intensity, and each of contacts  552 C and  552 D are assigned an intensity of contact of 4 intensity units of the aggregate intensity. More generally, in some implementations, each contact j is assigned a respective intensity Ij that is a portion of the aggregate intensity, A, in accordance with a predefined mathematical function, Ij=A·(Dj/ΣDi), where Dj is the distance of the respective contact j to the center of force, and ΣDi is the sum of the distances of all the respective contacts (e.g., i=1 to last) to the center of force. The operations described with reference to  FIGS. 5C-5D  can be performed using an electronic device similar or identical to device  100 ,  300 , or  500 . In some embodiments, a characteristic intensity of a contact is based on one or more intensities of the contact. In some embodiments, the intensity sensors are used to determine a single characteristic intensity (e.g., a single characteristic intensity of a single contact). It should be noted that the intensity diagrams are not part of a displayed user interface, but are included in  FIGS. 5C-5D  to aid the reader. 
     In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface optionally receives a continuous swipe contact transitioning from a start location and reaching an end location, at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location is, optionally, 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 is, optionally, 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 intensity of a contact on the touch-sensitive surface is, optionally, characterized relative to one or more intensity thresholds, such as a contact-detection intensity threshold, a light press intensity threshold, a deep press intensity threshold, and/or one or more other intensity thresholds. 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 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. 
     An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold to an intensity between the light press intensity threshold and the deep press intensity threshold 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 to an intensity above the deep press intensity threshold 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 to an intensity between the contact-detection intensity threshold and the light press intensity threshold 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 to an intensity below the contact-detection intensity threshold is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments, the contact-detection intensity threshold is zero. In some embodiments, the contact-detection intensity threshold is greater than zero. 
     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., 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., an “up stroke” of the respective press input). 
       FIGS. 5E-5H  illustrate detection of a gesture that includes a press input that corresponds to an increase in intensity of a contact  562  from an intensity below a light press intensity threshold (e.g., “IT L ”) in  FIG. 5E , to an intensity above a deep press intensity threshold (e.g., “IT D ”) in  FIG. 5H . The gesture performed with contact  562  is detected on touch-sensitive surface  560  while cursor  576  is displayed over application icon  572 B corresponding to App  2 , on a displayed user interface  570  that includes application icons  572 A- 572 D displayed in predefined region  574 . In some embodiments, the gesture is detected on touch-sensitive display  504 . The intensity sensors detect the intensity of contacts on touch-sensitive surface  560 . The device determines that the intensity of contact  562  peaked above the deep press intensity threshold (e.g., “IT D ”). Contact  562  is maintained on touch-sensitive surface  560 . In response to the detection of the gesture, and in accordance with contact  562  having an intensity that goes above the deep press intensity threshold (e.g., “IT D ”) during the gesture, reduced-scale representations  578 A- 578 C (e.g., thumbnails) of recently opened documents for App  2  are displayed, as shown in  FIGS. 5F-5H . In some embodiments, the intensity, which is compared to the one or more intensity thresholds, is the characteristic intensity of a contact. It should be noted that the intensity diagram for contact  562  is not part of a displayed user interface, but is included in  FIGS. 5E-5H  to aid the reader. 
     In some embodiments, the display of representations  578 A- 578 C includes an animation. For example, representation  578 A is initially displayed in proximity of application icon  572 B, as shown in  FIG. 5F . As the animation proceeds, representation  578 A moves upward and representation  578 B is displayed in proximity of application icon  572 B, as shown in  FIG. 5G . Then, representations  578 A moves upward,  578 B moves upward toward representation  578 A, and representation  578 C is displayed in proximity of application icon  572 B, as shown in  FIG. 5H . Representations  578 A- 578 C form an array above icon  572 B. In some embodiments, the animation progresses in accordance with an intensity of contact  562 , as shown in  FIGS. 5F-5G , where the representations  578 A- 578 C appear and move upwards as the intensity of contact  562  increases toward the deep press intensity threshold (e.g., “ITS”). In some embodiments, the intensity, on which the progress of the animation is based, is the characteristic intensity of the contact. The operations described with reference to  FIGS. 5E-5H  can be performed using an electronic device similar or identical to device  100 ,  300 , or  500 . 
     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., 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 descriptions 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 either: 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, and/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. 
     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that are implemented on an electronic device, such as portable multifunction device  100 , device  300 , or device  500 . 
       FIGS. 6A-6X  illustrate exemplary user interfaces for providing compass application features, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIG. 7 . 
       FIGS. 6A-6X  illustrate exemplary user interfaces for a compass application, in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIG. 7 . 
       FIG. 6A  depicts electronic device  600  displaying home screen  606  on display  602  (e.g., a touch-sensitive display). Home screen  606  includes a plurality of application icons for launching respective applications. In some embodiments, electronic device  600  includes one or more features of device  100 , device  300 , or device  500 . In the embodiment illustrated in  FIG. 6A , electronic device  600  includes rotatable input mechanism  604 , which is also depressible. In some embodiments, electronic device  600  includes one or more features of device  100 , device  300 , or device  500 . 
     At  FIG. 6A , a user performs a tap gesture to launch a compass application. As a result, while displaying home screen  606 , electronic device  600  detects input  608  at a location corresponding to compass icon  610 . 
     At  FIG. 6B , in response to detecting input  608 , electronic device  600  launches the compass application, and replaces display of home screen  606  with display of compass user interface  612  of a compass application. Compass user interface  612  provides an indication of a direction in which electronic device  600  is oriented (e.g., 0° N). In some embodiments, compass user interface  612  corresponds to a navigation mode for assisting a user with navigating a physical environment. 
     Compass user interface  612  includes needle  614  and dial  616 . Needle  614  provides an indication of one or more predefined directions. As shown in  FIG. 6B , needle  614  points north and south. In particular, the side of needle  614  with the solid portion is pointing north, while the side of needle  614  with the crosshatching is pointing south. Similarly, dial  616  provides an indication of one or more predefined directions. As depicted in  FIG. 6B , dial  616  includes markings (e.g., ticks) corresponding to 0° to 359°. Dial  616  includes labels corresponding to the markings at certain intervals to provide an indication of respective predefined directions. For example, the marking corresponding to 0° is labeled “N” for north. As another example, the marking corresponding to 240° is labeled “240”. Thus, needle  614 , dial  616 , or a combination thereof provides an indication of one or more predefined directions. In some embodiments, the movement of needle  614  is fixed to the movement of dial  616 , or vice versa. Thus, in some embodiments, needle  614  does not move relative to dial  616 . In some embodiments, dial  616  is displayed without needle  614 . 
     Compass user interface  612  also includes direction of travel indicator  618 , which provides an indication of the direction in which electronic device  600  is oriented and/or the direction in which the user intends to travel. Additionally, compass user interface  612  includes ring  620 , which includes elevation, incline, latitude, and longitude. 
     As shown in  FIG. 6B , electronic device  600  is oriented in the north direction. As a result, electronic device  600  displays compass user interface  612  with an indication that electronic device  600  is oriented in the north direction. For example, dial  616  is displayed such that the 0° N marking is aligned with direction of travel indicator  618 . For ease of explanation,  FIG. 6B  as well as subsequent figures depict compass rose  624  and north indicator  626 , which help to clarify the orientation of electronic device  600  with respect to north. For example, compass rose  624  includes device representation  624 A, which includes physical features (e.g., a representation of rotatable input mechanism  604 ) to illustrate the orientation of electronic device  600  with respect to compass rose  624 . Further, north indicator  626  is located in the north direction with respect to electronic device  600 . 
     As discussed below,  FIGS. 6B-6D  illustrate how compass user interface  612  is updated as electronic device  600  changes orientation relative to the north direction. With reference to  FIG. 6B , suppose the user wishes to travel west, so the user turns left towards the west direction. It is noted that, when the user turns, electronic device  600  moves in accordance with the movement of the user, as electronic device  600  is being worn on the user&#39;s wrist. At  FIG. 6C , as a result of the user turning, electronic device  600  rotates dial  616  clockwise, and updates compass user interface  612  to reflect the new direction in which electronic device  600  is oriented. In particular, compass user interface  612  provides an indication that electronic device  600  is oriented in the northwest direction at 330°. 
     With reference to  FIG. 6C , the user continues turning left until the user faces west. At  FIG. 6D , as a result of the continued turning, electronic device  600  updates compass user interface  612  to provide an indication that electronic device  600  is oriented in the west direction at 270°. 
     In some embodiments, the accuracy of dial  616  and its indication of direction can vary. Returning to  FIG. 6B , accuracy indicator  622  provides an indication of the accuracy of dial  616  and its indication of direction. For example, a high number of ticks (e.g., 5) in accuracy indicator  622  provides an indication that dial  616  has low accuracy. Thus, though dial  616  in  FIG. 6B  provides an indication that electronic device  600  is oriented in the north direction, accuracy indicator  622  indicates that this might be inaccurate.  FIG. 6C  depicts an improvement in accuracy of dial  616 , as the number of ticks in accuracy indicator  622  decreases. As depicted in  FIG. 6D , the ticks in accuracy indicator  622  cease to be displayed, indicating a high accuracy for dial  616 . In some embodiments, high accuracy for dial  616  can also be indicated by accuracy indicator  622  having a single tick. In some embodiments, after receiving additional inputs that enable higher accuracy measurements of direction (e.g., after motion that enables improved calibration) the number of ticks in the accuracy indicator decreases to indicate the increased accuracy (or reduced uncertainty) of the measurement. In some embodiments, after the device determines that the measurements of direction have a reduced accuracy (e.g., due to motion of the device or interference with sensors of the device such as a nearby magnetic field) the number of ticks in the accuracy indicator increases to indicate the reduced accuracy (or increased uncertainty) of the measurement. 
     With reference to  FIG. 6D , the user is facing west and compass user interface  612  has been updated accordingly, as discussed above. As shown in  FIG. 6D , the user performs a deep press gesture to navigate to a menu for setting a bearing. As a result, while displaying compass user interface  612 , electronic device  600  detects input  628 . In some embodiments, a bearing represents a direction in which the user intends to travel, such as towards a landmark. 
     At  FIG. 6E , in response to detecting input  628  and in accordance with a determination that an intensity of input  628  exceeds an intensity threshold, electronic device  600  replaces display of compass user interface  612  with display of bearing menu  634 . Bearing menu  634  includes affordance  630 A which, when selected, initiates a process for setting a bearing. In some embodiments, electronic device  600  replaces display of compass user interface  612  with display of bearing menu  634  regardless of the location at which input  628  is detected. 
     As shown in  FIG. 6E , the user selects affordance  630 A via a tap gesture. As a result, while displaying bearing menu  634 , electronic device  600  detects tap gesture  632  at a location corresponding to affordance  630 A. 
     At  FIG. 6F , in response to detecting tap gesture  632 , electronic device  600  replaces display of bearing menu  634  with display of modified compass user interface  637 . Modified compass user interface  637  includes one or more features of compass user interface  612 , including needle  614 , dial  616 , and direction of travel indicator  618 . Additionally, modified compass user interface  637  includes done affordance  638 A and cancel affordance  638 B. In some embodiments, modified compass user interface  637  corresponds to an edit mode for setting a bearing. 
     As depicted in  FIG. 6F , the user begins rotating rotatable input mechanism  604  counterclockwise to adjust the bearing towards a landmark in the southwest direction at 240°. While displaying modified compass user interface  637 , electronic device  600  detects, via rotatable input mechanism  604 , input  636 A with a magnitude and directional component. 
     At  FIG. 6G , in response to detecting input  636 A, electronic device  600  displays bearing indicator  640 , where the size of bearing indicator  640  is based on the magnitude of input  636 A. Further, the displayed location of bearing indicator  640  is based on the directional component of input  636 A. For example, in some embodiments, if the directional component of input  636 A was in the opposite direction, bearing indicator  640  would be displayed to the right of direction of travel indicator  618 . For ease of explanation,  FIG. 6G  depicts compass rose  624  with bearing direction  624 B. Bearing direction  624 B illustrates the direction of the bearing (e.g., 240°) relative to electronic device  600 . 
     As shown in  FIG. 6G , the user continues rotating rotatable input mechanism  604  to adjust the bearing to 240° from North. As a result, electronic device  600  continues detecting input  636 A via rotatable input mechanism  604 . At  FIG. 6H , in response to continued detection of input  636 A, electronic device  600  increases the size of bearing indicator  640  based on the magnitude of input  636 A. In particular, bearing indicator  640  increases in size such that bearing indicator  640  corresponds to 240° (e.g., the direction of the landmark towards which the user intends to travel). In some embodiments, bearing indicator  640  represents an amount of offset from the current direction in which electronic device  600  is oriented. 
     As depicted in  FIG. 6H , the user sets the bearing by selecting done affordance  638 A via a tap gesture. As a result, electronic device  600  detects input  642  at a location corresponding to done affordance  638 A. At  FIG. 6I , in response to detecting input  642 , electronic device  600  replaces display of modified compass user interface  637  with display of compass user interface  612 . Compass user interface  612  in  FIG. 6I  includes bearing indicator  640 , which represents a bearing that is set at 240°. 
     As discussed above, the bearing is set in the direction of a landmark at 240° to which the user intends to travel. At  FIG. 6I , the user is facing west at 270° from North. Bearing indicator  640  provides an indication that the user needs to turn left by a certain amount in order to face 240°. The user starts to turn left to face the landmark at 240°. 
     As shown in  FIG. 6J , as a result of the user turning left, electronic device  600  updates compass user interface  612  to reflect the new direction in which electronic device  600  is oriented. In particular, compass user interface  612  provides an indication that electronic device  600  is oriented in the southwest direction at 255° from North. Additionally, updating compass user interface  612  includes changing bearing indicator  640  based on the movement of electronic device  600  relative to a predefined direction (e.g., north). As a result, bearing indicator  640  decreases in size as the electronic device  600  moves more closely towards the desired direction of 240°. At  FIG. 6J , the user continues to turn left to face 240°. 
     At  FIG. 6K , as a result of the continued turning, electronic device  600  faces the direction of the bearing at 240°. Accordingly, electronic device  600  updates user interface  612  to provide an indication that electronic device  600  is oriented in the southwest direction at 240°. At this point, the user and electronic device  600  are facing the landmark at 240°, and the user can travel towards the landmark using compass user interface  612  as a guide. 
     As depicted in  FIG. 6K , the user rotates rotatable input mechanism  604  to scroll for additional details. As a result, while displaying compass user interface  612 , electronic device  600  detects input  636 B. At  FIG. 6L , in response to detecting input  636 B, electronic device  600  scrolls compass user interface  612  and displays additional information. The additional information includes an indication of the direction in which electronic device  600  is oriented (e.g., 240°), incline angle (e.g., 2°), bearing (e.g., 240°), ground elevation (e.g., 2,850 feet), latitude (e.g., 89° 59′59″ N), and longitude (e.g., 179° 59′59″ W). It is noted that, in contrast to input  636 A in  FIG. 6F-6G , rotating the rotatable input mechanism  604  at  FIG. 6K  (e.g., once the bearing has been set) does not change the bearing. Thus, electronic device  600  does not, for example, change the size of bearing indicator  640  in response to rotation of rotatable input mechanism  604  at  FIG. 6K . 
     Returning to  FIG. 6L , the user rotates rotatable input mechanism  604  to scroll to the top of compass user interface  612 . As a result, electronic device  600  detects input  636 C, and in response, returns to displaying compass user interface  612 , as shown in  FIG. 6M . At  FIG. 6M , the user performs a deep press gesture to navigate back to bearing menu  634 . As a result, while displaying compass user interface  612 , electronic device  600  detects input  644 . 
     At  FIG. 6N , in response to detecting input  644  and in accordance with a determination that an intensity of input  644  exceeds an intensity threshold, electronic device  600  replaces display of compass user interface  612  with display of bearing menu  634 . In contrast to bearing menu  634  in  FIG. 6E , bearing menu  634  in  FIG. 6N  also includes affordance  630 B which, when selected, clears the set bearing. In some embodiments, electronic device  600  displays affordance  630 B in response to detecting input  644  and in accordance with a determination that a bearing has been set. In some embodiments, clearing the set bearing causes bearing indicator  640  to cease to be displayed in compass user interface  612 . As an example, in response to detecting input  648  (e.g., tap gesture) at affordance  630 B, electronic device  600  replaces display of bearing menu  634  with display of compass user interface  612  without bearing indicator  640 . Thus, electronic device  600  would return to displaying compass user interface  612  in  FIG. 6B  (prior to the bearing being set by the user), with the exception that compass user interface  612  would reflect that electronic device  600  is oriented to 240° (e.g., the 240° marker of dial  616  would be aligned with direction of travel indicator  618 ). 
     In some embodiments, electronic device  600  detects input  646  at affordance  630 A and, in response, electronic device  600  replaces display of bearing menu  634  with display of modified compass user interface  637  in  FIG. 6F , with the exception that modified compass user interface  637  would reflect that electronic device  600  is oriented to 240° (e.g., the 240° marker of dial  616  would be aligned with direction of travel indicator  618 ). 
     Returning to  FIG. 6N , the user depresses rotatable input mechanism  604 . As a result, electronic device  600  detects input  650  via rotatable input mechanism  604 . At  FIG. 6O , in response to detecting input  650 , electronic device  600  returns to displaying compass user interface  612 .  FIG. 6N  and previous figures such as  FIG. 6M  depict compass user interface  612  with level indicator  613 A. With reference to  FIG. 6M , level indicator  613 A is substantially centered relative to compass user interface  612  (e.g., dial  616 ), which provides an indication that electronic device  600  is substantially parallel to the ground. In contrast, level indicator  613 A in  FIG. 6O  is not substantially centered, which provides an indication that electronic device  600  is not substantially parallel to the ground. It is noted that level indicator  613 A is used when electronic device  600  is oriented within a threshold range of orientations that correspond to measuring an orientation of the device relative to the ground. 
       FIG. 6P  depicts incline indicator  613 B, which is used when electronic device  600  is oriented within a threshold range of orientations that correspond to measuring an orientation of the device relative to the direction of gravity. At  FIG. 6P , the user has raised their wrist such that electronic device  600  is substantially parallel with to the direction of gravity. The user then rotates electronic device  600  to align the device with the slope angle of the ground. As shown in  FIG. 6P , incline indicator  613 B points to 2° as the slope angle, which provides an indication that the ground is roughly flat. In some embodiments, when electronic device  600  is oriented within a threshold range of orientations for measuring an orientation of the device relative to the direction of gravity, level indicator  613 A ceases to be displayed. 
       FIGS. 6Q-6R  depict compass user interface  612  when the sensor data used to determine the orientation of electronic device  600  relative to a predefined direction is insufficient (e.g., not detected). When the sensor data is insufficient, electronic device  600  does not provide a valid indication of the orientation of electronic device  600  relative to a predefined direction. In some embodiments, in response to determining that the sensor data is insufficient, electronic device  600  displays compass user interface  612  with indicators  652  and  654 , each of which provides an indication of insufficient sensor data. As illustrated in  FIGS. 6Q-6R , electronic device  600  animates indicator  652  such that indicator  652  moves around dial  616  as time elapses. 
       FIGS. 6S-6X  depict clock faces that include information from the compass application. With reference to  FIG. 6I , the user turns right to face 300° and performs one or more inputs to navigate to a clock face. As a result, in response to detecting the one or more inputs, electronic device  600  displays clock face  656  in  FIG. 6S , in accordance with some embodiments. Clock face  656  includes an indication of the time and date. Additionally, clock face  1800  includes complications  656 A- 656 D. In some embodiments, a complication refers to a clock face feature other than those used to indicate the hours and minutes of a time (e.g., clock hands or hour/minute indications). In some embodiments, complications provide different types of information to a user, such as data obtained from an application. In some embodiments, the information conveyed to a user by a complication is customizable. In some embodiments, a complication that is displayed at a particular location on the display can be configured to be displayed at a different location on the clock face. In some embodiments, a complication or a version thereof can be displayed at two different locations on the clock face. In some embodiments, in response to detecting an input (e.g., tap gesture) at a complication, electronic device  600  replaces display of a clock face (e.g.,  656 ) with display of a user interface for an application corresponding to the selected complication (e.g., compass application). 
     As shown in  FIG. 6S , clock face  656  includes complication  656 A and  656 C, each of which provides an indication of the direction (e.g., 300°) in which electronic device  600  is oriented relative to a predefined direction (e.g., north). Clock face  656  also includes complication  656 D, which provides an indication of the elevation of electronic device  600 . Moreover, clock face  656  includes complication  656 B, which also provides an indication of the direction in which electronic device  600  is oriented relative to the predefined direction. In particular, complication  656 B includes dial  656 B- 1 , which serves the same function as dial  616  in compass user interface  612 , and bearing indicator  656 B- 2 , which serves the same function as bearing indicator  640  in compass user interface  612 . 
       FIGS. 6S-6U  illustrate how complication  656 B is updated as the orientation of electronic device  600  changes with respect to a predefined direction (e.g., north). At  FIG. 6S , the user turns left to face the direction of the bearing at 240°. At  FIG. 6T , as result of the user turning, electronic device  600  updates clock face  656  to reflect the new direction in which electronic device  600  is oriented. Accordingly, dial  656 B- 1  slides to the right such that 270° is substantially centered, and bearing indicator  656 B- 2  reduces in size. Further, complications  656 A and  656 C change from 300° to 270°. With reference to  FIG. 6T , the user continues to turn left to face the direction of the bearing at 240°. At  FIG. 6U , as a result of the continued turning, electronic device  600  updates clock face  656  and the appropriate complications (e.g.,  656 A- 656 C) to indicate that electronic device  600  is now oriented to 240°. 
       FIG. 6V-6X  depict alternative clock faces for displaying data from the compass application. At  FIG. 6V , electronic device  600  displays clock face  658 , which includes complications  658 A- 658 G and  656 D. Complications  658 A- 658 B provide indications of latitude and longitude, respectively. For example, complications  658 A- 658 B include numerical values for latitude and longitude, as shown in  FIG. 6V . Complications  658 C- 658 E and  658 G provide an indication of the direction (e.g., 240°) in which electronic device  600  is oriented relative to a predefined direction (e.g., north). Additionally, complication  658 F provides an indication of the elevation of electronic device  600 . At  FIG. 6W , electronic device  600  displays clock face  656 , which has been configured to display a different arrangement of complications, as compared to  FIG. 6U . For example, clock face  656  in  FIG. 6W  does not include complication  656 B of  FIG. 6U . Instead, clock face  656  includes complication  656 A at a new location as compared to  FIG. 6U . Further, clock face  656  includes complication  656 E, which provides an indication of the direction in which electronic device  600  is oriented relative to a predefined direction. At  FIG. 6X , electronic device  600  displays clock face  660  with complication  660 A, which also provides an indication of the direction in which electronic device  600  is oriented relative to a predefined direction. 
       FIG. 7  is a flow diagram illustrating an exemplary process for a compass application, in accordance with some embodiments. Method  700  is performed at a device (e.g.,  100 ,  300 ,  500 ,  600 ) with a display device and a rotatable input mechanism (e.g., a physical crown that has a fixed axis about which the physical crown rotates relative to the display device and a housing of the electronic device). Some operations in method  700  are, optionally, combined, the orders of some operations are, optionally, changed, and some operations are, optionally, omitted. 
     As described below, method  700  provides an intuitive way for setting a bearing in a compass application. The method reduces the cognitive burden on a user for setting a bearing, thereby creating a more efficient human-machine interface. For battery-operated computing devices, enabling a user to set a bearing faster and more efficiently conserves power and increases the time between battery charges. 
     The electronic device (e.g.,  600 ) displays ( 702 ), via the display device (e.g.,  602 ), a compass user interface (in an edit mode) (e.g.,  637 ) with a direction indicator (e.g.,  614 ,  616 ) and a bearing indicator (e.g.,  640 ), wherein: the direction indicator (e.g., a user interface element (e.g., chevron/needle/dial) that points to a predefined compass direction such as north, where the user interface element rotates on the display device as the device rotates so that the user interface element continues to point to north) provides an indication of a respective compass direction (e.g., a direction relative to the earth&#39;s magnetic field such as a cardinal direction (e.g., north (e.g., true north, magnetic north), south, west, east)), wherein the appearance of the direction indicator is determined based on the orientation of the electronic device relative to the respective compass direction; and the bearing indicator provides an indication of an offset from the respective compass direction (e.g., a direction relative to the earth&#39;s magnetic field) (e.g., while concurrently displaying the direction indicator and/or the direction of travel indicator e.g.,  618 )). 
     In some embodiments, the direction indicator (e.g.,  614 ,  616 ) includes one or more of numerical elements (e.g., degrees), textual elements (e.g., cardinal directions), graphical dial (e.g.,  616 ), and a graphical needle (e.g.,  614 ). In some embodiments, the location/orientation of the direction indicator on the display device (e.g.,  602 ) changes (e.g., with respect to a fixed point on the display device) based on (e.g., in response to) a change in orientation of the device relative to the particular direction. In some embodiments, the compass user interface (e.g.,  637 ) includes a direction of travel indicator (e.g.,  618 ), which is displayed at a fixed location/orientation on the display of the electronic device regardless of the change in orientation of the electronic device. In some embodiments, the direction of travel indicator provides an indication of the orientation of the electronic device with respect to the environment (e.g., the direction the electronic device and, optionally, the user is facing) direction in which the user intends to travel. In some embodiments, the location/orientation of the direction of travel indicator (on the display) does not change based on (e.g., in response to) a change in orientation of the device relative to the particular direction.) 
     In some embodiments, the bearing indicator (e.g.,  640 ) includes a first point at a location (e.g.,  618 ) corresponding to the respective compass direction (e.g., the direction in which the device is currently facing/oriented towards) and/or a second point at a location corresponding to the direction of the bearing indicator (e.g., the direction in which the user intends to travel). In some embodiments, the bearing indicator includes a graphical arc between the first point and the second point. In some embodiments, the graphical arc changes in size in response to the device (e.g.,  600 ) detecting rotation of the rotatable input mechanism (e.g.,  604 ). In some embodiments, the user configures the bearing indicator to set a direction pointing at a landmark to which the user wants to travel. In some embodiments, displaying the compass user interface (in the edit mode) (e.g.,  637 ) includes changing visual characteristics (e.g., reducing opacity, darkening, blurring, ceasing display) of displayed elements (e.g.,  614 ,  616 ) on the display device (e.g., the direction indicator or a portion thereof).) 
     While displaying the bearing indicator (e.g.,  640 ) (in an edit mode), the electronic device (e.g.,  600 ) detects ( 704 ) rotation (e.g., via input  636 A) of the rotatable input mechanism (e.g.,  604 ) (and, optionally, while concurrently displaying the bearing indicator and the direction indicator (e.g.,  614 ,  616 )). 
     In response ( 706 ) to detecting rotation of the rotatable input mechanism, the electronic device (e.g.,  600 ) changes ( 708 ) the displayed position of the bearing indicator (e.g.,  640 ) from a first position to a second position (e.g., relative to a position of the direction indicator) by an amount that is determined in accordance with a magnitude (and, optionally, direction) of the rotation (e.g., via input  636 A) of the rotatable input mechanism (e.g.,  604 ) (e.g., such that changing the position of the bearing indicator to the second position changes the amount of offset of the bearing indicator with the respective compass direction). Changing the displayed position of the bearing indicator via the rotatable input mechanism allows the user to precisely set the bearing while the compass user interface is displayed on a small display. Use of the rotatable input mechanism enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user efficiently set the bearing in the compass application) which, additionally, reduces power usage and improves battery life of the device by enabling the users to use the devices more quickly and efficiently. 
     In some embodiments, changing the displayed position of the bearing indicator includes rotating the bearing indicator (e.g., in cases where the bearing indicator is a needle similar to needle  614 ). In some embodiments, in response to detecting rotation of the rotatable input mechanism (e.g.,  604 ), a first point of the bearing indicator remains fixed while a second point of the bearing indicator changes. In some embodiments, further detecting rotation of the rotatable input mechanism results in changing the displayed position of the bearing indication from the second position to a third position. In some embodiments, detecting further rotation of the rotatable input mechanism results in changing the displayed position of the bearing indication from the third position to the first position. In some embodiments, the amount of change in the displayed position of the bearing indicator is based on the detected amount (e.g., magnitude, speed, and/or duration) of rotation of the rotatable input mechanism. In some embodiments, the amount of change in the displayed position of the bearing indicator is proportional to the detected amount of rotation of the rotatable input mechanism. 
     In some embodiments, detecting a change in orientation of the electronic device (e.g.,  600 ) relative to the respective compass direction causes the displayed position of the bearing indicator (e.g.,  640 ) to change in the first mode (e.g., a non-edit mode, when compass user interface  612  is displayed). In some embodiments, detecting a change in orientation of the electronic device relative to the respective compass direction does not cause the displayed position of the bearing indicator to change in the second mode (e.g., an edit mode, when compass user interface  637  is displayed). In some embodiments, detecting rotation of the rotatable input mechanism (e.g.,  604 ) causes the displayed position of the bearing indicator to change in the second mode (e.g., an edit mode, when compass user interface  637  is displayed). In some embodiments, detecting rotation of the rotatable input mechanism does not cause the displayed position of the bearing indicator to change in the first mode (e.g., a non-edit mode, when compass user interface  612  is displayed). In some embodiments, activating the “done” button (e.g.,  638 A) (e.g., while in the second mode, an edit mode) causes the bearing indicator to be set relative to north as shown on the display (e.g.,  602 ). In some embodiments, while in the second mode (e.g., an edit mode, when compass user interface  637  is displayed), the displayed position of the bearing indicator does not change in response to the electronic device detecting a change in orientation of the electronic device relative to the respective compass direction. 
     In some embodiments, prior to displaying the compass user interface (e.g.,  637 ), the electronic device (e.g.,  600 ) displays, via the display device (e.g.,  602 ), a second compass user interface (e.g.,  612 , a navigation mode, a first mode) with the direction indicator (e.g.,  614 ,  616 ) and the bearing indicator (e.g.,  640 ). In some embodiments, the second compass user interface does not include the bearing indicator. In some embodiments, the direction indicator provides an indication of the respective compass direction (e.g., a direction relative to the earth&#39;s magnetic field such as a cardinal direction (e.g., north (e.g., true north, magnetic north), south, west, east)). In some embodiments, the appearance of the direction indicator is determined based on the orientation of the electronic device relative to the respective compass direction. 
     In some embodiments, the bearing indicator (e.g.,  640 ) provides an indication of an offset (e.g., thus providing an indication of the direction to a destination to which the user intends to travel) from the respective compass direction (e.g., a direction relative to the earth&#39;s magnetic field) (e.g., while concurrently displaying the direction of travel indicator (e.g.,  618 )). In some embodiments, the user configures the bearing indicator to set a direction pointing at a landmark to which the user wants to travel. In some embodiments, the bearing indicator is configured to indicate that there is no offset from the respective compass direction. In some embodiments, displaying the bearing setting user interface (e.g.,  637 ) includes changing visual characteristics (e.g., reducing opacity, darkening, blurring, ceasing display) of displayed elements on the display device (e.g., the direction indicator or a portion thereof). In some embodiments, the bearing indicator includes a first point at a location corresponding to the respective compass direction (e.g., the direction in which the device is currently facing/oriented towards) and/or a second point at a location corresponding to the direction of the bearing indicator (e.g., the direction in which the user intends to travel). In some embodiments, the bearing indicator includes a graphical arc between the first point and the second point. In some embodiments, the graphical arc changes in size in response to the device detecting a change in orientation relative to the respective compass direction. Thus, when the graphical arc ceases to display, the electronic device is oriented directly towards the direction of the bearing indicator (e.g., the direction in which the user intends to travel). In some embodiments, even when the electronic device is oriented directly towards the direction of the bearing indicator, the bearing indicator continues to be displayed. 
     In some embodiments, while displaying the bearing indicator (e.g.,  640 ) (in the first position, in the navigation mode (e.g., when compass user interface  612  is displayed) different from the edit mode), the electronic device (e.g.,  600 ) detects rotation (e.g., via input  636 B) of the rotatable input mechanism (e.g.,  604 ) (and, optionally, while concurrently displaying the bearing indicator and the direction indicator). In some embodiments, in response to detecting rotation of the rotatable input mechanism, the electronic device forgoes changing the displayed position of (e.g., forgoing rotating) the bearing indicator (e.g.,  640 ) relative to the direction indicator (e.g.,  614 ,  616 ) (e.g., thereby not changing the amount of offset of the bearing indicator with the respective compass direction). Forgoing changing the displayed position in response to detecting rotation of the rotatable input mechanism requires the user to enter an edit mode to set the bearing. Since the user needs to enter an edit mode to adjust the bearing using the rotatable input mechanism, accidental changes to a previously set bearing (e.g., the current bearing setting) are avoided while in the navigation mode. Preventing unintentional changes to the set bearing enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping to avoid extraneous inputs that would otherwise be needed to correct the set bearing) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, the electronic device (e.g.,  600 ) displays (concurrently with the direction indicator and the bearing indicator), via the display device (e.g.,  602 ), a first representation of a first geographic information (e.g., longitude as depicted in ring  620  of  FIG. 6B , a geographic coordinate that specifies the east—west position of the electronic device on the Earth&#39;s surface) of the electronic device and a second representation of a second geographic information (e.g., latitude as depicted in ring  620  of  FIG. 6B , a geographic coordinate that specifies the north—south position of the electronic device on the Earth&#39;s surface) of the electronic device. Exemplary geographic information of the electronic device includes: geographic coordinates (longitude, latitude) of the location electronic device, elevation (e.g., height above or below a fixed reference point (such as the surface of the Earth or sea level) as depicted in ring  620  of  FIG. 6B ) of the location of the electronic device, and incline (e.g., angle from horizontal as depicted in ring  620  of  FIG. 6B ) of the orientation of the electronic device. In some embodiments the first representation of the first geographic information and the second representation of the second geographic information are arranged in a circle (e.g.,  620 ) or an arc (a minor arc, a major arc) of a circle. In some embodiments, the direction indicator (e.g.,  614 ,  616 ) and/or bearing indicator are configured to rotate using the center of the circle (e.g.,  620 ) as a pivot point. In some embodiments, the first representation of the first geographic information and the second representation of the second geographic information are displayed in both the edit mode (e.g., when compass user interface  637  is displayed) and the navigation mode (e.g., when compass user interface  612  is displayed). In some embodiments, the display of the representations of the geographic information is updated live (e.g., continuously, periodically) based on information collected by the electronic device. 
     In some embodiments, while displaying (e.g., in the navigation mode) the first representation of the first geographic information (e.g., longitude as depicted in ring  620  of  FIG. 6K ) at a first size (and optionally at a first orientation (e.g., non-horizontal) on the display device) and the second representation of the second geographic information (e.g., latitude as depicted in ring  620  of  FIG. 6K ) at a second size (and optionally at a second orientation on the display device), the electronic device (e.g.,  600 ) detects a scroll input (e.g.,  636 B) that includes a directional component (e.g., a swipe up input on a touch-sensitive surface, a rotation of the rotatable input mechanism (e.g.,  604 )). 
     In some embodiments, in response to detecting the scroll input (e.g.,  636 B), the electronic device shifts the compass user interface (e.g.,  612 ) in accordance with the directional component to display: a third representation (e.g., longitude information as depicted in the bottom portion of  FIG. 6L ) of the first geographic information at a third size that is larger than the first size (and optionally at a third orientation (e.g., horizontal) different from the first orientation on the display device) and a fourth representation (e.g., latitude information as depicted in the bottom portion of  FIG. 6L ) of the second geographic information at a fourth size that is larger than the second size (e.g., and at a fourth orientation (e.g., horizontal) different from the second orientation on the display device). 
     In some embodiments, detecting the scroll input (e.g.,  636 B) (while in the navigation mode (e.g., when compass user interface  612  is displayed)) causes the direction indicator (e.g.,  614 ,  616 ) and the bearing indicator (e.g.,  640 ) (or at least a portion thereof) to scroll off of the display (e.g.,  602 ) and for geographic information to scroll onto the display (e.g., as shown in  FIG. 6L ). In some embodiments, in response to detecting the scroll input (while in the navigation mode), the electronic device (e.g.,  600 ) displays one or more of (or all of) a numerical heading (e.g., in degrees) based on the orientation of the electronic device, a numerical incline (e.g., in degrees) based on the orientation of the electronic device, a numerical bearing (e.g., in degrees) that is not based on the orientation of the electronic device, a numerical ground elevation (e.g., in feet) that is based on the geographic location of the electronic device, a numerical longitude and numerical latitude (e.g., in degrees) that are based on the geographic location of the electronic device. In some embodiments, the third representation provides a more precise value for the first geographic information as compared to the first representation, and the fourth representation provides a more precise value for the second geographic information as compared to the second representation. In some embodiments, in response to detecting the scroll input, the electronic device displays one or more additional geographic information(s) that were not displayed concurrently with the first representation of the first geographic information. In some embodiments, in response to detecting the scroll input (e.g.,  636 B, detecting rotation of the rotatable input mechanism (e.g.,  604 )), the electronic device forgoes changing the displayed position of (e.g., forgoing rotating) the bearing indicator (e.g.,  640 ) relative to the direction indicator (e.g.,  614 ,  616 ) (thereby not changing the amount of offset of the bearing indicator with the respective compass direction). 
     In some embodiments, the displayed third representation of the first geographic information and the fourth representation of the second geographic information (e.g., as depicted in  FIG. 6L ) are updated (e.g., periodically, continuously, repeatedly) to reflect an updated location or orientation of the electronic device (e.g.,  600 ). In some embodiments, the electronic device displays (e.g., adjacent to the respective geographic information) an amount of time in which the respective geographic information was last updated (e.g., “7M AGO” as shown in  FIG. 6 ). In some embodiments, the displayed first representation of the first geographic information and the second representation of the second geographic information are updated (e.g., periodically, continuously, repeatedly) to reflect an updated location or orientation of the electronic device. 
     In some embodiments, prior to displaying the compass user interface (e.g.,  637 ), the electronic device (e.g.,  600 ) displays, via the display device (e.g.,  602 ), the second compass user interface (e.g.,  612 , a navigation mode, a first mode) with the direction indicator (e.g.,  614 ,  616 ) (and optionally without the bearing indicator (e.g.,  640 )). In some embodiments, the direction indicator provides an indication of the respective compass direction (e.g., a direction relative to the earth&#39;s magnetic field such as a cardinal direction (e.g., north (e.g., true north, magnetic north), south, west, east)), wherein the appearance of the direction indicator is determined based on the orientation of the electronic device relative to the respective compass direction. 
     In some embodiments, the electronic device (e.g.,  600 ) detects, via the touch-sensitive surface (e.g., of display device  602 ), a user input (e.g.,  628 , at a location corresponding to the second compass user interface (e.g.,  612 ), at a location corresponding to the direction indicator (e.g.,  614 ,  616 ). In some embodiments, in response to detecting the user input (e.g.,  628 ): in accordance with a determination that a characteristic intensity of the user input exceeds an intensity threshold (e.g., a non-zero threshold), the electronic device displays an edit affordance (e.g.,  630 A) which, when selected, results in display of the compass user interface (e.g., 637) (e.g.,  637 , edit mode, a second mode) (and optionally independent of a location of the user input (e.g.,  628 ) on the touch-sensitive surface). Requiring the user to enter an edit mode to set the bearing prevents accidental changes to the set bearing while in the navigation mode. Preventing unintentional changes to the set bearing enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping to avoid extraneous inputs that would otherwise be needed to correct the set bearing) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     In some embodiments, in response to detecting the user input (e.g.,  628 ): in accordance with a determination that the second compass user interface (e.g.,  612 ) includes the bearing indicator (e.g.,  640 ) (e.g., in accordance with a determination that a bearing has been set for the device (e.g., via input  642 )), the electronic device displays, via the display device, a clear affordance (e.g.,  630 B) which, when selected (e.g., via input  648 ), initiates a process for removing the bearing indicator from the second compass user interface (e.g.,  612 ), wherein the clear affordance is concurrently displayed with the edit affordance. In some embodiments, initiating the process including displaying the second compass user interface (e.g.,  612 ) without the bearing indicator (e.g.,  640 ). In some embodiments, in accordance with a determination that the second compass user interface does not include the bearing indicator, the electronic device forgoes display of the clear affordance (e.g.,  630 B). 
     In some embodiments, displaying the compass user interface (e.g.,  637 ) includes emphasizing the bearing indicator (e.g.,  640 ) while de-emphasizing one or more displayed visual objects (e.g.,  614 ,  616 ). In some embodiments, displaying the compass user interface (e.g.,  637 ) includes changing a visual property (e.g., opacity, brightness, color) of the direction indicator (e.g., dimming the direction indicator (e.g.,  614 ,  616 )) while maintaining the visual property of the bearing indicator (e.g., not dimming the bearing indicator (e.g.,  640 )). In some embodiments, displaying the compass user interface (e.g.,  637 ) includes visually changing (e.g., opacity, brightness, color, dimming) the direction indicator, the first representation of the first geographic information, and the second representation of the second geographic information, while maintaining the bearing indicator (e.g., not dimming the bearing indicator), thereby emphasizing the bearing indicator. 
     In some embodiments, in response to detecting the user input (e.g.,  628 ): in accordance with a determination that the characteristic intensity of the user input does not exceed the intensity threshold (e.g., a non-zero threshold), the electronic device (e.g.,  600 ) forgoes displaying the edit affordance (e.g.,  630 A). In some embodiments, the edit affordance is displayed as part of a menu user interface (e.g.,  634 ) that include options (e.g., edit affordance  630 A, clear affordance  630 B) for configuring a bearing indicator (e.g.,  640 ). 
     In some embodiments, displaying the compass user interface (e.g.,  637 , in an edit mode) includes displaying (e.g., concurrently with the direction indicator and the bearing indicator) a done affordance (e.g.,  638 A). In some embodiments, subsequent to changing the displayed position of the bearing indicator from the first position to the second position, the electronic device receives a second user input (e.g.,  642 ). In some embodiments, in response to receiving the second user input: in accordance with a determination that the second user input corresponds to activation of the done affordance, the electronic device transitions from the compass user interface (e.g.,  637 , in an edit mode) to the second compass user interface (e.g.,  612 , in a navigation mode) and maintains the displayed position of the bearing indicator (e.g.,  640  in  FIGS. 6H-6I ) in the second position (e.g., relative to a position of the direction indicator). 
     In some embodiments, displaying the compass user interface (e.g.,  637 , in an edit mode) further includes displaying (e.g., concurrently with the direction indicator and the bearing indicator) a cancel affordance (e.g.,  638 B). In response to receiving the second user input, and in accordance with a determination that the second user input corresponds to activation of the cancel affordance, the electronic device (e.g.,  600 ) transitions from the compass user interface (e.g.,  637 , in an edit mode) to the second compass user interface (e.g.,  612 , in a navigation mode) and without maintaining the displayed position of the bearing indicator (e.g.,  640 ) in the second position relative to the position of the direction indicator (and optionally reverts the displayed position of the bearing indicator to the first position). 
     In some embodiments, while displaying the second compass user interface (e.g.,  612 , a navigation mode, a first mode) including the direction indicator (e.g.,  614 ,  616 ), the electronic device (e.g.,  600 ) detects a change in orientation of the electronic device. In some embodiments, in response to detecting the change in orientation of the electronic device, the electronic device displays an indication (e.g.,  613 A- 613 B) of the amount of offset at which the electronic device is oriented relative to a fixed orientation (e.g., in comparison to horizontal or vertical) (and optionally ceasing to display the direction indicator). 
     In some embodiments, displaying the indication (e.g.,  613 A- 613 B) of the amount of offset at which the electronic device is oriented relative to the fixed orientation includes: in accordance with a determination that the electronic device is in a first range of orientations (e.g., substantially parallel to the ground, within a threshold range of a predefined orientation (e.g., parallel to the ground)) while detecting the change in orientation of the electronic device, the indication of the amount of offset includes a first visual object (e.g.,  613 A, bubble). In some embodiments, displaying the indication of the amount of offset at which the electronic device is oriented relative to the fixed orientation includes: in accordance with a determination that the electronic device is in a second range of orientations different from the first range of orientations (e.g., substantially vertical with respect to the ground, within a threshold range of a predefined orientation (e.g., vertical with respect to the ground)) while detecting the change in orientation of the electronic device, the indication of the amount of offset includes a second visual object (e.g.,  613 B, an arrow) that is different from the first visual object. 
     In some embodiments, the first visual object (e.g.,  613 A) includes a bubble and the bubble size increases as the electronic device becomes less parallel to the ground, and decreases as the electronic device moves to be closer to parallel to the ground. In some embodiments, the electronic device displays an animation (e.g., flashing the bubble) indicating when the first criteria are satisfied (e.g., within a threshold range of being parallel relative to the ground). In some embodiments, the second visual object (e.g.,  613 B) includes an arrow that points to a displayed number representing a slope angle with respect to gravity&#39;s direction. 
     In some embodiments, displaying the direction indicator (e.g.,  614 ,  616 ) includes displaying an indication (e.g.,  622 ) of accuracy of the direction indicator. In some embodiments, in accordance with a determination that the accuracy of the direction indicator has a first degree of accuracy, the electronic device (e.g.,  600 ) displays the indication of accuracy with a first appearance. In some embodiments, in accordance with a determination that the accuracy of the direction indicator has a second degree of accuracy different from the first degree of accuracy, the electronic device displays the indication of accuracy with a second appearance that is different from the first appearance. Thus, the indication of the accuracy of the direction indicator visually changes in accordance with the electronic device determining that the accuracy of the direction indicator has changed. In some embodiments, the indication of the accuracy of the direction indicator includes an indication of a range (e.g., of degrees). In some embodiments, the indication (e.g.,  622 ) includes one or more tick marks along a path of a circle, wherein as the accuracy of the direction indicator decreases the quantity of tick marks in the indication increases (e.g., 1 tick mark means high accuracy, 5 tick marks means lower accuracy). In some embodiments, the tick marks are a predefined distance from each other. In some embodiments, the indication includes visually differentiating (e.g., highlighting, changing color, enlarging) one or more tick marks (from among a plurality of tick marks along a path of a circle), wherein as the accuracy of the direction indicator decreases the quantity of tick marks visually differentiated increases (e.g., 1 differentiated tick mark means high accuracy, 5 differentiated tick marks means lower accuracy). 
     In some embodiments, prior to (and/or while) displaying the compass user interface (e.g.,  637 ) (and optionally prior to (and/or while) displaying the second compass user interface (e.g.,  612 )), the electronic device (e.g.,  600 ) initiates a process to detect (e.g., using one or more sensors of the electronic device) sensor data (e.g., device location, device GPS data, device orientation data). In some embodiments, initiating the process causes the device to detect data that is sufficient to use. In some embodiments, initiating the process does not cause the device to detect data that is sufficient to use (e.g., no data is detected, data detected is not complete). In some embodiments, prior to (and/or while) displaying the compass user interface (and optionally prior to (and/or while) displaying the second compass user interface): in accordance with failing to detect data that satisfies a data sufficiency criteria (e.g., insufficient GPS data, insufficient data about the orientation of the electronic device relative to the respective compass direction), the electronic device displays an indication (e.g.,  652 ,  654 ) (changing a visual appearance (e.g., dimming, change opacity, swinging back-and-forth, and/or rotating) of the directional indicator (e.g.,  614 )) that the data sufficient criteria has not been met. In some embodiments, prior to (and/or while) displaying the compass user interface (and optionally prior to (and/or while) displaying the second compass user interface): in accordance with detecting data that satisfies the data sufficiency criteria (e.g., sufficient GPS data, sufficient data about the orientation of the electronic device relative to the respective compass direction), the electronic device forgoes displaying the indication that the data sufficient criteria has not been met. 
     In some embodiments, displaying the indication that the data sufficient criteria has not been met includes one or more of: dimming a portion (or all) of the compass user interface (e.g.,  612 ) (e.g., the direction indicator (e.g.,  614 ,  616 ) or a portion thereof), animating the direction indicator (e.g., moving back and forth between two positions), and causing one or more user interface elements to repeatedly flash/blink. 
     In some embodiments, while displaying the direction indicator (e.g.,  614 ,  616 ) (e.g., as part of the navigation mode or edit mode of the compass application, when compass user interface  612  is displayed), the electronic device detects a third user input (e.g., a gesture to return to a predetermined clock face (e.g.,  656 ,  658 ,  660 )). In some embodiments, the third user input is one or more inputs (e.g., depresses) of the rotatable input mechanism (e.g.,  604 ). In some embodiments, in response to detecting the third user input, the electronic device (e.g.,  600 ) displays a clock face (e.g.,  656 ,  658 ,  660 ) that indicates the current time, wherein the clock face further includes (current display of) a compass object (e.g.,  656 A- 656 E,  658 A- 658 G,  660 A). In some embodiments, while displaying the clock face that indicates the current time and includes the compass object, the electronic device detects activation of (e.g., tap gesture at a location on a touch-sensitive surface corresponding to the location of) the compass object. In some embodiments, in response to detecting activation of the compass object, the electronic device displays a second compass user interface (e.g.,  612 , in the navigation mode, not the edit mode) that includes the direction indicator (e.g.,  614 ,  616 ) that provides an indication of the respective compass direction, wherein the appearance of the direction indicator is determined based on the orientation of the electronic device relative to the respective compass direction (e.g., and ceasing to display the clock face). 
     In some embodiments, the compass object (e.g.,  656 A- 656 E,  658 A- 658 G,  660 A) includes: a representation of a third geographic information (e.g., longitude as depicted in  FIG. 6V , a geographic coordinate that specifies the east-west position of the electronic device on the Earth&#39;s surface) of the electronic device (e.g.,  600 ) that updates as a location or orientation of the electronic device changes, and a representation of a fourth geographic information (e.g., latitude as depicted in  FIG. 6V , a geographic coordinate that specifies the north-south position of the electronic device on the Earth&#39;s surface) of the electronic device that updates as the location or orientation of the electronic device changes. Exemplary geographic information of the electronic device includes: geographic coordinates (longitude, latitude) of the location electronic device, elevation (e.g., height above or below a fixed reference point (such as the surface of the Earth or sea level) as depicted in  FIGS. 6S-6V ) of the location of the electronic device, and incline (angle (e.g., 2°) from horizontal as depicted in  FIG. 6V ) of the orientation of the electronic device. In some embodiments, the electronic device concurrently displays a plurality of complications (e.g.,  656 A- 656 E,  658 A- 658 G,  660 A) (e.g., received for the same compass application) that have different geographic information. In some embodiments, the electronic device detects an input (e.g., tap gesture) at a location corresponding to a complication (e.g., a representation of geographic information). In some embodiments, in response to detecting the input at the location corresponding to the complication, the electronic device launches an application corresponding to the complication. Thus, the electronic device displays a user interface (e.g.,  612 ) of the application (e.g., a compass application). 
     In some embodiments, the compass object (e.g.,  656 B) includes a second bearing indicator (e.g.,  656 B- 2 ) that provides an indication of the offset from the respective compass direction. In some embodiments, the visual appearance of the second bearing indicator changes as the orientation of the electronic device changes with respect to a predefined direction such as north. In some embodiments, the second bearing indicator is a (colored) portion that is located between a representation of the direction in which the device is currently oriented (e.g., 300° from North in  FIG. 6S ) and a representation of the direction corresponding to the bearing indicator (e.g., 240° in  FIG. 6S ). In some embodiments, the clock face (e.g.,  656 ) includes a complication (e.g.,  656 B) that includes a bearing indicator complication (e.g.,  656 B- 2 ) that provides an indication of an offset from the respective compass direction. 
     In some embodiments, the compass object (e.g.,  656 B) includes an orientation indicator (e.g.,  656 B- 1 , a dial, a needle that slides across a scale, a scale that slides past a needle) that moves laterally on the display (e.g., does not rotate around a point on the display), wherein the orientation indicator provides an indication of the orientation of the electronic device (e.g., as the device detects changes in the orientation of the electronic device). In some embodiments, the clock face (e.g.,  656 ) includes a complication (e.g.,  656 B) that includes needle/dial (e.g.,  656 B- 1 ) that moves laterally on the display (e.g., instead of rotating) as the orientation of the electronic device changes, wherein the needle/dial indicates a direction in which the electronic device (e.g.,  600 ) is oriented (e.g., a direction relative to the earth&#39;s magnetic field such as a cardinal direction (e.g., north (e.g., true north, magnetic north), south, west, east)). Providing an indication of the orientation of the electronic device provides the user with visual feedback about the orientation of the user in relation to the set bearing. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     Subsequent to displaying the compass user interface (e.g.,  637 ) (e.g., and after the bearing has been set (e.g., via input  642 )), the electronic device (e.g.,  600 ) displays ( 710 ), via the display device (e.g.,  602 ), a third compass user interface (e.g.,  612  in  FIG. 6I ) (e.g., a navigation mode, a first mode) with the direction indicator (e.g.,  614 ,  616 ) and the bearing indicator (e.g.,  640 ), wherein a visual appearance of the bearing indicator changes as the orientation of the electronic device changes (relative to a predefined direction such as north) (e.g., as depicted in  FIGS. 6I-6K ). In some embodiments, the visual appearance of the bearing indicator (e.g.,  640 ) changes while the third compass user interface (e.g.,  612 ) is displayed. Changing the visual appearance of the bearing indicator as the orientation of the electronic device changes provides the user with visual feedback about the orientation of the electronic device and the user in relation to the set bearing. Providing improved visual feedback to the user enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user to provide proper inputs and reducing user mistakes when operating/interacting with the device) which, additionally, reduces power usage and improves battery life of the device by enabling the user to use the device more quickly and efficiently. 
     The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the techniques and their practical applications. Others skilled in the art are thereby enabled to best utilize the techniques and various embodiments with various modifications as are suited to the particular use contemplated. 
     Although the disclosure and examples have been fully described with reference to the accompanying drawings, it is to be noted that various changes and modifications will become apparent to those skilled in the art. Such changes and modifications are to be understood as being included within the scope of the disclosure and examples as defined by the claims. 
     As described above, one aspect of the present technology is the gathering and use of data available from various sources to provide certain compass application features. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, twitter IDs, home addresses, data or records relating to a user&#39;s health or level of fitness (e.g., vital signs measurements, medication information, exercise information), date of birth, or any other identifying or personal information. 
     The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to enhance compass application features. Accordingly, use of such personal information data enables users to have a richer experience within the compass application. Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. For instance, health and fitness data may be used to provide insights into a user&#39;s general wellness, or may be used as positive feedback to individuals using technology to pursue wellness goals. 
     The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should occur after receiving the informed consent of the users. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of or access to certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country. 
     Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of a compass application, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app. 
     Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user&#39;s privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods. 
     Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, location data can be inferred based on non-personal information data or a bare minimum amount of personal information, other non-personal information available to the compass application, or publicly available information.
