RELATED APPLICATIONS 
     This application claims priority to U.S. Provisional Patent Application No. 61/184,828, “Device, Method, and Graphical User Interface for Providing Maps, Directions, and Location-Based Information,” filed Jun. 7, 2009, which is incorporated by reference herein in its entirety. 
    
    
     TECHNICAL FIELD 
     The disclosed embodiments relate generally to electronic devices with displays and touch-sensitive surfaces that execute mapping applications. More particularly, the disclosed embodiments relate to portable electronic devices with touch screen displays that execute mapping applications with multiple viewing modes. 
     BACKGROUND 
     Portable electronic devices that execute mapping applications to provide map and routing information have become quite popular recently. The devices typically include map control functions, capabilities for searching for and displaying points of interest, and capabilities for displaying routes from a current location to a search result. 
     Mapping applications on such devices typically allow the mapping information to be viewed in a variety of ways, such as with the top of the map corresponding to a fixed direction (e.g., north), the top of the map corresponding to a current heading, the map centered on the current location of the device, the map displaying search results, the map displaying routing information, etc. 
     Unfortunately, selecting and changing map viewing modes on existing devices is cumbersome and not intuitive, thereby creating a significant cognitive burden on a user. In addition, existing methods take longer than necessary, thereby wasting energy. This latter consideration is particularly important in battery-operated devices. 
     Accordingly, there is a need for potable electronic devices with faster, more efficient and intuitive methods for changing between map viewing modes. Such methods and interfaces reduce the cognitive burden on a map user and produce a more efficient human-machine interface. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges. 
     SUMMARY 
     The above deficiencies and other problems associated with user interfaces for electronic devices with mapping applications are reduced or eliminated by the disclosed devices. The device is portable (e.g., a handheld device). In some embodiments, the device has a touchpad. In some embodiments, the device has a touch-sensitive display (also known as a “touch screen” or “touch screen display”). In some embodiments, the device has a graphical user interface (GUI), one or more processors, memory and one or more modules, programs or sets of instructions stored in the memory for performing multiple functions. In some embodiments, the user interacts with the GUI primarily through finger contacts and gestures on the touch-sensitive surface. In some embodiments, in addition to mapping, the functions may include one or more of: image editing, drawing, presenting, word processing, website creating, disk authoring, spreadsheet making, game playing, telephoning, video conferencing, e-mailing, instant messaging, workout support, digital photographing, digital videoing, web browsing, digital music playing, and/or digital video playing. Executable instructions for performing these functions may be included in a computer readable storage medium or other computer program product configured for execution by one or more processors.

     Embodiments of computing devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the computing 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® and iPod Touch® devices from Apple Inc. of Cupertino, Calif. 
     In the discussion that follows, a computing device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the computing device may include one or more other physical user-interface devices, such as a physical keyboard, a mouse and/or a joystick. 
     The device supports a variety of applications in addition to the mapping application, 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 may be executed on the device may 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 may be 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 may support the variety of applications with user interfaces that are intuitive and transparent. 
     The user interfaces may include one or more soft keyboard embodiments. The soft keyboard embodiments may include standard (QWERTY) and/or non-standard configurations of symbols on the displayed icons of the keyboard, such as those described in U.S. patent application Ser. Nos. 11/459,606, “Keyboards For Portable Electronic Devices,” filed Jul. 24, 2006, and 11/459,615, “Touch Screen Keyboards For Portable Electronic Devices,” filed Jul. 24, 2006, the contents of which are hereby incorporated by reference in their entirety. The keyboard embodiments may include a reduced number of icons (or soft keys) relative to the number of keys in existing physical keyboards, such as that for a typewriter. This may make it easier for users to select one or more icons in the keyboard, and thus, one or more corresponding symbols. The keyboard embodiments may be adaptive. For example, displayed icons may be modified in accordance with user actions, such as selecting one or more icons and/or one or more corresponding symbols. One or more applications on the device may utilize common and/or different keyboard embodiments. Thus, the keyboard embodiment used may be tailored to at least some of the applications. In some embodiments, one or more keyboard embodiments may be tailored to a respective user. For example, one or more keyboard embodiments may be tailored to a respective user based on a word usage history (lexicography, slang, individual usage) of the respective user. Some of the keyboard embodiments may be adjusted to reduce a probability of a user error when selecting one or more icons, and thus one or more symbols, when using the soft keyboard embodiments. 
     Attention is now directed towards embodiments of portable devices with touch-sensitive displays.  FIGS. 1A and 1B  are block diagrams illustrating portable multifunction devices  100  with touch-sensitive displays  112  in accordance with some embodiments. The touch-sensitive display  112  is sometimes called a “touch screen” for convenience, and may also be known as or called a touch-sensitive display system.

The device  100  may include one or more optical sensors  164 . These components may communicate over one or more communication buses or signal lines  103 . 
     It should be appreciated that the device  100  is only one example of a portable multifunction device  100 , and that the device  100  may have more or fewer components than shown, may combine two or more components, or a may have a different configuration or arrangement of the components. The various components shown in  FIGS. 1A and 1B  may be 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  may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory  102  by other components of the device  100 , such as the CPU  120  and the peripherals interface  118 , may be controlled by the memory controller  122 . Memory  102 , or the non-volatile memory of memory  102 , includes one or more computer readable storage mediums. 
     The peripherals interface  118  couples the input and output peripherals of the device to the 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 the device  100  and to process data. 
     In some embodiments, the peripherals interface  118 , the CPU  120 , and the memory controller  122  may be implemented on a single chip, such as a chip  104 . In some other embodiments, they may be implemented on separate chips. 
     The RF (radio frequency) circuitry  108  receives and sends RF signals, also called electromagnetic signals. The RF circuitry  108  converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals.

     The audio circuitry  110 , the speaker  111 , and the microphone  113  provide an audio interface between a user and the device  100 . The audio circuitry  110  receives audio data from the peripherals interface  118 , converts the audio data to an electrical signal, and transmits the electrical signal to the speaker  111 . The speaker  111  converts the electrical signal to human-audible sound waves. The audio circuitry  110  also receives electrical signals converted by the microphone  113  from sound waves. The audio circuitry  110  converts the electrical signal to audio data and transmits the audio data to the peripherals interface  118  for processing. Audio data may be retrieved from and/or transmitted to memory  102  and/or the RF circuitry  108  by the peripherals interface  118 . In some embodiments, the audio circuitry  110  also includes a headset jack (e.g.  212 ,  FIG. 2 ). The headset jack provides an interface between the 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). 
     The I/O subsystem  106  couples input/output peripherals on the device  100 , such as the touch screen  112  and other input/control devices  116 , to the peripherals interface  118 . The I/O subsystem  106  may include a display controller  156  and one or more input controllers  160  for other input or control devices. The one or more input controllers  160  receive/send electrical signals from/to other input or control devices  116 . The other input/control devices  116  may 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  may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g.,  208 ,  FIG. 2 ) may include an up/down button for volume control of the speaker  111  and/or the microphone  113 . The one or more buttons may include a push button (e.g.,  206 ,  FIG. 2 ). A quick press of the push button may disengage a lock of the touch screen  112  or begin 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, which is hereby incorporated by reference in its entirety. A longer press of the push button (e.g.,  206 ) may turn power to the device  100  on or off. The user may be able to customize a functionality of one or more of the buttons. The touch screen  112  is used to implement virtual or soft buttons and one or more soft keyboards. 
     The touch-sensitive touch screen  112  provides an input interface and an output interface between the device and a user. The display controller  156  receives and/or sends electrical signals from/to the touch screen  112 . The touch screen  112  displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects. 
     A 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. The touch screen  112  and the 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 the touch screen  112  and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on the touch screen. In an exemplary embodiment, a point of contact between a touch screen  112  and the user corresponds to a finger of the user. 
     The touch screen  112  may use LCD (liquid crystal display) technology, or LPD (light emitting polymer display) technology, although other display technologies may be used in other embodiments. The touch screen  112  and the display controller  156  may 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 a 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 the touch screen  112  may be analogous to the multi-touch sensitive tablets described in the following U.S. Pat. Nos. 6,323,846 (Westerman et al.), 6,570,557 (Westerman et al.), and/or 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, a touch screen  112  displays visual output from the portable device  100 , whereas touch sensitive tablets do not provide visual output. 
     A touch-sensitive display in some embodiments of the touch screen  112  may be as 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. 
     The touch screen  112  may have a resolution in excess of 100 dpi. In an exemplary embodiment, the touch screen has a resolution of approximately 160 dpi. The user may make contact with the 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 are much 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, the device  100  may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from the touch screen  112  or an extension of the touch-sensitive surface formed by the touch screen. 
     In some embodiments, the device  100  may include a physical or virtual click wheel as an input control device  116 . A user may navigate among and interact with one or more graphical objects (e.g., icons) displayed in the touch screen  112  by rotating the click wheel or by moving a point of contact with the click wheel (e.g., where the amount of movement of the point of contact is measured by its angular displacement with respect to a center point of the click wheel). The click wheel may also be used to select one or more of the displayed icons. For example, the user may press down on at least a portion of the click wheel or an associated button. User commands and navigation commands provided by the user via the click wheel may be processed by an input controller  160  as well as one or more of the modules and/or sets of instructions in memory  102 . For a virtual click wheel, the click wheel and click wheel controller may be part of the touch screen  112  and the display controller  156 , respectively. For a virtual click wheel, the click wheel may be either an opaque or semitransparent object that appears and disappears on the touch screen display in response to user interaction with the device. In some embodiments, a virtual click wheel is displayed on the touch screen of a portable multifunction device and operated by user contact with the touch screen. 
     The device  100  also includes a power system  162  for powering the various components. The power system  162  may include 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. 
     The device  100  may also include one or more optical sensors  164 .  FIGS. 1A and 1B  show an optical sensor coupled to an optical sensor controller  158  in I/O subsystem  106 . The optical sensor  164  may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. The optical sensor  164  receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with an imaging module  143  (also called a camera module), the optical sensor  164  may capture still images or video. In some embodiments, an optical sensor is located on the back of the device  100 , opposite the touch screen display  112  on the front of the device, so that the touch screen display may be used 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 may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of the 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  may be used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     The device  100  may also include one or more proximity sensors  166 .  FIGS. 1A and 1B  show a proximity sensor  166  coupled to the peripherals interface  118 . Alternately, the proximity sensor  166  may be coupled to an input controller  160  in the I/O subsystem  106 . The proximity sensor  166  may perform as described in U.S. patent application Ser. Nos. 11/241,839, “Proximity Detector In Handheld Device”; 11/240,788, “Proximity Detector In Handheld Device”; 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and 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 the 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). In some embodiments, the proximity sensor keeps the screen off when the device is in the user&#39;s pocket, purse, or other dark area to prevent unnecessary battery drainage when the device is a locked state. 
     The device  100  may also include one or more accelerometers  168 .  FIGS. 1A and 1B  show an accelerometer  168  coupled to the peripherals interface  118 . Alternately, the accelerometer  168  may be coupled to an input controller  160  in the I/O subsystem  106 . The accelerometer  168  may perform as described in U.S. Patent Publication No. 20050190059, “Acceleration-based Theft Detection System for Portable Electronic Devices,” and U.S. Patent Publication No. 20060017692, “Methods And Apparatuses For Operating A Portable Device Based On An Accelerometer,” both of which are which are incorporated by reference herein in their entirety. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. 
     The device  100  may also include a magnetometer  169 .  FIGS. 1A and 1B  show a magnetometer  169  coupled to the peripherals interface  118 . Alternately, the magnetometer  169  may be coupled to an input controller  160  in the I/O subsystem  106 . The magnetometer is used to determine the orientation of the device. 
     In some embodiments, the software components stored in memory  102  (e.g., in a computer readable storage medium of memory  102 ) may include an operating system  126 , a communication module (or set of instructions)  128 , a contact/motion module (or set of instructions)  130 , a graphics module (or set of instructions)  132 , a text input module (or set of instructions)  134 , a Global Positioning System (GPS) module (or set of instructions)  135 , and applications (or set of instructions)  136 . 
     The operating system  126  (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     The 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 the RF circuitry  108  and/or the external port  124 . The 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. 
     The contact/motion module  130  may detect contact with the touch screen  112  (in conjunction with the display controller  156 ) and other touch sensitive devices (e.g., a touchpad or physical click wheel). The 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 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). The 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, may include 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 may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, the contact/motion module  130  and the display controller  156  detects contact on a touchpad. In some embodiments, the contact/motion module  130  and the controller  160  detects contact on a click wheel. 
     The contact/motion module  130  may detect a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns. Thus, a gesture may be detected by detecting a particular contact pattern. For example, detecting a finger tap gesture comprises detecting a finger-down event followed by detecting a finger-up 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 comprises detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up event. 
     In some embodiments, the contact/motion module  130  ( FIG. 1B ) detects finger swipe gestures, and implements scrolling of information on the display ( 112 ,  FIG. 2 ) of the device when one or more finger swipe gestures made with a user&#39;s finger meet predefined criteria. 
     The graphics module  132  includes various known software components for rendering and displaying graphics on the touch screen  112  or other display, including components for changing the intensity 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, the graphics module  132  stores data representing graphics to be used. Each graphic may be assigned a corresponding code. The 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 . 
     The text input module  134 , which may be 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). 
     The 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). 
     The applications  136  may include the following modules (or sets of instructions), or a subset or superset thereof:
         a contacts module  137  (sometimes called an address book or contact list);   a telephone module  138 ;   a video conferencing module  139 ;   an e-mail client module  140 ;   an instant messaging (IM) module  141 ;   a workout support module  142 ;   a camera module  143  for still and/or video images;   an image management module  144 ;   a video player module  145 ;   a music player module  146 ;   a browser module  147 ;   a calendar module  148 ;   widget modules  149 , which may include 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  145  and music player module  146 ;   notes module  153 ;   map module  154 ; and/or   online video module  155 .       

     Examples of other applications  136  that may be 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. 
     In conjunction with touch screen  112 , display controller  156 , contact module  130 , graphics module  132 , and text input module  134 , the contacts module  137  may be used to manage an address book or contact list, including: adding name(s) to the address book; deleting name(s) from the address book; associating telephone number(s), e-mail address(es), physical address(es) or other information with a name; associating an image with a name; categorizing and sorting names; providing telephone numbers or e-mail addresses to initiate and/or facilitate communications by telephone  138 , video conference  139 , e-mail  140 , or IM  141 ; and so forth.

     Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules may be combined or otherwise re-arranged in various embodiments. For example, video player module  145  may be combined with music player module  146  into a single module (e.g., video and music player module  152 ,  FIG. 1B ). In some embodiments, memory  102  may store a subset of the modules and data structures identified above. Furthermore, memory  102  may store additional modules and data structures not described above. 
     In some embodiments, the device  100  is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen  112  and/or a touchpad. By using a touch screen and/or a touchpad as the primary input/control device for operation of the device  100 , the number of physical input/control devices (such as push buttons, dials, and the like) on the device  100  may be reduced. 
     The predefined set of functions that may be performed exclusively through a touch screen and/or a touchpad include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates the device  100  to a main, home, or root menu from any user interface that may be displayed on the device  100 . In such embodiments, the touchpad may be referred to as a “menu button.” In some other embodiments, the menu button may be a physical push button or other physical input/control device instead of a touchpad. 
       FIG. 2  illustrates a portable multifunction device  100  having a touch screen  112  in accordance with some embodiments. The touch screen may display one or more graphics within user interface (UI)  200 . In this embodiment, as well as others described below, a user may select one or more of the graphics by making contact or touching the graphics, for example, with one or more fingers  202  (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 contact may include a gesture, such as 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 the device  100 . In some embodiments, inadvertent contact with a graphic may not select the graphic. For example, a swipe gesture that sweeps over an application icon may not select the corresponding application when the gesture corresponding to selection is a tap. 
     The device  100  may also include one or more physical buttons, such as “home” or menu button  204 . As described previously, the menu button  204  may be used to navigate to any application  136  in a set of applications that may be executed on the device  100 . Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI in touch screen  112 . 
     In one embodiment, the device  100  includes a touch screen  112 , a menu button  204 , a push button  206  for powering the device on/off and locking the device, volume adjustment button(s)  208 , a Subscriber Identity Module (SIM) card slot  210 , a head set jack  212 , and a docking/charging external port  124 . The push button  206  may be 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, the device  100  also may accept verbal input for activation or deactivation of some functions through the microphone  113 . 
     Attention is now directed towards embodiments of user interfaces (“UI”) that may be implemented on a portable multifunction device  100 . 
       FIG. 3  illustrates an exemplary user interface for unlocking a portable electronic device in accordance with some embodiments. In some embodiments, user interface  300  includes the following elements, or a subset or superset thereof:
         Unlock image  302  that is moved with a finger gesture to unlock the device;   Arrow  304  that provides a visual cue to the unlock gesture;   Channel  306  that provides additional cues to the unlock gesture;   Time  308 ;   Day  310 ;   Date  312 ; and       

     Wallpaper image  314 . 
     In some embodiments, the device detects contact with the touch-sensitive display (e.g., a user&#39;s finger making contact on or near the unlock image  302 ) while the device is in a user-interface lock state. The device moves the unlock image  302  in accordance with the contact. The device transitions to a user-interface unlock state if the detected contact corresponds to a predefined gesture, such as moving the unlock image across channel  306 . Conversely, the device maintains the user-interface lock state if the detected contact does not correspond to the predefined gesture. As noted above, processes that use gestures on the touch screen to unlock the device are described in U.S. patent application Ser. Nos. 11/322,549, “Unlocking A Device By Performing Gestures On An Unlock Image,” filed Dec. 23, 2005, and 11/322,550, “Indication Of Progress Towards Satisfaction Of A User Input Condition,” filed Dec. 23, 2005, which are hereby incorporated by reference in their entirety.

     In some embodiments, user interface  400 B includes the following elements, or a subset or superset thereof:
           402 ,  404 ,  405 ,  406 ,  141 ,  148 ,  144 ,  143 ,  149 - 3 ,  149 - 2 ,  149 - 1 ,  149 - 4 ,  410 ,  414 ,  138 ,  140 , and  147 , as described above;   Map  154 ;   Notes  153 ;   Settings  412 , which provides access to settings for the device  100  and its various applications  136 , as described further below;   Video and music player module  152 , also referred to as iPod (trademark of Apple Inc.) module  152 ; and   Online video module  155 , also referred to as YouTube (trademark of Google Inc.) module  155 .       

     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on an electronic device with a display and a touch-sensitive surface, such as portable multifunction device  100 . 
       FIGS. 5A-5T  illustrate exemplary user interfaces in a mapping application in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below with respect to  FIGS. 6A-6C . 
     UI  500 A ( FIG. 5A ) illustrates a user interface on a portable electronic device, here portable multifunction device  100  with touch screen  112 . A map  500  is displayed on the touch screen  112  of the device  100  by a mapping application  154 . A mapping mode user interface element  502  is displayed in a first appearance, here  502 - 1 , which indicates the mapping application is in an untracked mode. The untracked mode displays the map on the display  112  with an orientation that is independent of a current orientation of the portable electronic device. Here, as depicted in UI  500 A, the map  500  is in the untracked mode and current location icon  504  is not maintained at a substantially fixed location on the touch screen  112 . 
     UI  500 A also depicts that a search has taken place for search terms  506  (i.e. “Infinite Loop Cupertino California”), and a search result icon  508  is depicted at the location on the map corresponding to the search result. 
     UI  500 A also depicts a user gesture  510  (e.g., a finger tap), at the location of the mapping mode user interface element  502 . 
     UI  500 B ( FIG. 5B ) illustrates that in response to detecting user gesture  510 , the mapping application has entered a tracked mode. The tracked mode includes: displaying a current location icon  504  on the map  500  that corresponds to a current location of the electronic device  100 ; displaying the map on the touch screen  112  with an orientation that is independent of a current orientation of the electronic device  100 ; and maintaining the current location icon  504  at a substantially fixed location on the touch screen  112  as the current location of the electronic device  100  changes. Here, UI  500 B depicts that the mapping application has moved the current location icon  504  to a substantially central location on the touch screen  112 . Further the mapping mode user interface element  502  has been altered to be displayed in a second appearance  502 - 2 , indicating that the mapping application is in the tracked mode. 
     UI  500 B also depicts a user gesture  514  at the location of the mapping mode user interface element  502 . 
     Finally, note that UI  500 B depicts that map  500  is in a first location  500 - 1  with a given orientation (e.g., the map depicts U.S. Highway  280  in a left-to-right orientation) that is independent of a current orientation of the electronic device  100 . 
     UI  500 C ( FIG. 5C ) illustrates that in response to detecting user gesture  514 , the mapping application has entered a heading mode. The heading mode displays the current location icon  504 . The heading mode also displays the map  500  on the display with an orientation that corresponds to the current orientation of the portable electronic device determined with the magnetometer. Here, map  500  is in a second location  500 - 2  with a different orientation than that depicted in UI  500 B, (i.e., the map in UI  500 C is depicted with U.S. Highway  280  in a roughly bottom-to-top orientation based on the orientation of the electronic device  100 ). The heading mode also maintains the current location icon  504  at a substantially fixed location on the touch screen  112  as the current location of the electronic device  100  changes (e.g., a substantially central location on the touch screen  112 ). In some embodiments, the heading mode also displays a current location region indicia  516  that depicts the approximate area within which the electronic device  100  is physically located. 
     UI  500 C also depicts the mapping mode user interface element  502  has been altered to be displayed in a third appearance  502 - 3 , indicating that the mapping application is in the heading mode. 
     UI  500 C also depicts that, in some embodiments, while in the heading mode, the current location icon  504  is displayed with a heading indicator  518 - 1  which may include an arc that corresponds to the orientation of the device. 
     UI  500 D ( FIG. 5D ) depicts a different location  500 - 3  on the map  500 , which is displayed in heading mode as indicated by mapping mode user interface element  502 - 3  and heading indicator  518 - 2 . Note that heading indicator  518 - 2  is narrower than heading indicator  518 - 1  ( FIG. 5C ). In some embodiments, the heading indicator  518  may be an arc that has an angular range that varies in accordance with an uncertainty in the orientation of the device, and the angular range of the arc may be updated as the mapping application detects changing uncertainty in the orientation of the electronic device  100 . 
     UI  500 D also depicts that a user gesture  520  is detected on the touch screen  112 , a small finger scrolling gesture that includes a finger contact  520 - 1  followed by a small movement  520 - 2  on the touch screen  112 . 
     UI  500 E ( FIG. 5E ) illustrates that in response to detecting the small finger scrolling gesture  520 , the mapping application entered the tracked mode, as indicated by the appearance of mapping mode user interface element  502 - 2  and the change in the orientation of the map to an orientation that is independent of the current orientation of the portable electronic device. Note that in some embodiments, as depicted here, entering the tracked mode may also return the current location icon  504 , which may have moved in response to a user gesture such as user gesture  520 , to the substantially fixed location on the touch screen  112 . This return of the current location icon may result from a user gesture moving the map less than a predefined amount on the touch screen  112 . 
     UI  500 D also depicts that a larger finger scrolling gesture  522  is detected on the touch screen  112 , which includes a finger contact  522 - 1  followed by a larger movement  522 - 2  on the touch screen  112  than the movement  520 - 2 . 
     UI  500 F ( FIG. 5F ) illustrates that in response to detecting the larger finger scrolling gesture  522 , the mapping application enters the untracked mode, as indicated by mapping mode user interface element  502 - 1 , and the repositioned and reoriented map  500 - 4 . 
     UI  500 F also illustrates two user gestures  524  (e.g., two single-tap gestures) at the location of the mapping mode user interface element  502 . 
     UI  500 G ( FIG. 5G ) illustrates that in response to detecting two user gestures  524 , the mapping application entered the heading mode as indicated by mapping mode user interface element  502 - 3  and heading indicator  518 - 3 , and reoriented the map  500  and current location icon  504  to account for the current orientation of the electronic device  100 . 
     UI  500 G also illustrates a user gesture  528  on search icon  529 , indicating the user wants to do a search in the mapping application. 
     UI  500 H ( FIG. 5H ) illustrates that in response to user gesture  528 , the mapping application initiated a search input UI. A user entered a search into search box  532 , namely, a search term  534  (i.e., “BJ&#39;s restaurant &amp; brewery”). UI  500 H also illustrates a user gesture  536  on search icon  538 , which initiates a search with the entered search term  534 . 
     UI  500 I ( FIG. 5I ) illustrates that in response to user gesture  536 , the mapping application displays a search result  540  for “BJ&#39;s Restaurant &amp; Brewery.” The mapping application has also entered the tracked mode, as indicated by mapping mode user interface element  502 - 2  and the change in orientation of the map. UI  500 I also illustrates a user gesture  542  on mapping mode user interface element  502 . 
     UI  500 J ( FIG. 5J ) illustrates that in response to user gesture  542 , the mapping application has entered the heading mode as indicated by mapping mode user interface element  502 - 3 , the change in map orientation, and, in this example, by heading indicator  518 - 4 . 
     UI  500 J also illustrates a user gesture  544  on search icon  529 , indicating the user wants to do another search in the mapping application. 
     UI  500 K ( FIG. 5K ) depicts that in response to user gesture  544 , the mapping application initiated a search input UI. A user entered a search into search box  532 , namely, a search term  546  (i.e., “Coffee”). UI  500 K also illustrates a user gesture  548  on search icon  538 , which initiates a search with the entered search term  546 . 
     UI  500 L ( FIG. 5L ) illustrates that in response to user gesture  548 , the mapping application has displayed search results  550 - 1 ,  550 - 2 , and  550 - 3  for “Coffee,” and one result is highlighted with an information tag  551 . The mapping application has also entered the untracked mode, as indicated by mapping mode user interface element  502 - 1 , because in this example, the displayed search results moved the map greater than a predefined amount on the touch screen display (discussed more below). In essence, because the search results were far enough away from current location icon  504 , the mapping application exited tracked mode and redisplayed the map in a new location  500 - 5  that permitted display of the search results. 
     UI  500 L also illustrates a user gesture  552  on mapping mode user interface element  502 . 
     UI  500 M ( FIG. 5M ) illustrates that in response to detecting user gesture  552 , the mapping application entered the tracked mode as indicated by mapping mode user interface element  502 - 2 , and repositioned the map  500  to location  500 - 6 , with the current location icon  504  centered on the map. 
     UI  500 M also illustrates a user gesture  554  on search icon  529 , indicating the user wants to do yet another search in the mapping application. 
     UI  500 N ( FIG. 5N ) illustrates that in response to user gesture  554 , the mapping application initiated a search input UI. A user entered the same search as depicted in UI  500 H, and initiated the search with user gesture  556 . 
     UI  500 O ( FIG. 5O ) illustrates that in response to user gesture  556 , the mapping application remains in the tracked mode, as indicated by mapping mode user interface element  502 - 2 . The mapping application remains in the tracked mode because the search result was less than a predefined distance away from the current location icon  504 . The map  500  is repositioned to location  500 - 7 , with the current location icon  504  centered on the map. 
     UI  500 O also depicts user gesture  558  on search icon  529 , indicating the user wants to do another search in the mapping application. 
     UI  500 P ( FIG. 5P ) depicts that in response to user gesture  558 , the mapping application initiated a search input UI, like that depicted in UI  500 K, and a user gesture  560  on search icon  538  invokes the search. 
     UI  500 Q ( FIG. 5Q ) depicts that in response to user gesture  560 , although the mapping application was in tracked mode at the time of the search, the mapping application enters the untracked mode as indicated by mapping mode user interface element  502 - 1 , and repositions the map  500  to location  500 - 8 . In essence, because the search results were far enough away from current location icon  504 , the mapping application exited tracked mode and redisplayed the map in a new location  500 - 8  that permitted display of the search results. 
     UI  500 Q also depicts user gesture  562  at search location  550 - 2 , which selects search result  550 - 2 . 
     UI  500 R ( FIG. 5R ) depicts that the mapping application has entered heading mode after selecting search result  550 - 2 , as indicated by mapping mode user interface element  502 - 3  and heading indicator  518 - 5 . In this example, the mapping application is displaying the map at location  500 - 9 . In some embodiments, a route between current location icon  504  and a selected search result may be depicted (e.g., the route line  564  between current location icon  504  and selected search result  550 - 2 ). 
     UI  500 S ( FIG. 5S ) depicts that as the electronic device  100  changes location when the mapping application is in heading mode, the mapping application may update current location icon  504 , heading indicator  518 - 6 , and map orientation (compare current location icon  504  in UI  500 R versus current location icon  504  in UI  500 S, which is further along route  564 , and thus, the mapping application is displaying the map at a location  500 - 10 , as well as updating the angular range of heading indicator  518 - 5  versus  518 - 6 ). Thus, in some embodiments, as the electronic device changes in location and orientation, the angular range of the heading indicator may be updated. Further, in some embodiments, as the electronic device changes in location and orientation with respect to a route to a selected search result, the angular range of the heading indicator may be updated. 
     UI  500 S also depicts user gesture  566  at mapping mode user interface element  502 - 3 . 
     UI  500 T ( FIG. 5T ) illustrates that in response to user gesture  566 , the mapping application has entered the untracked mode, as indicated by mapping mode user interface element  502 - 1 , as well as the map being reoriented to be displayed at location  500 - 11 . 
     In some embodiments, mapping mode user interface element  502  may be used to toggle through each of the modes, i.e., starting from untracked mode, one activation of mapping mode user interface element  502  causes the mapping application to enter tracked mode, a second activation of mapping mode user interface element  502  causes the mapping application to enter the heading mode, and a third activation of mapping mode user interface element  502  causes the mapping application to enter untracked mode again. 
       FIGS. 6A-6C  are flow diagrams illustrating a method of changing between map viewing modes in accordance with some embodiments. The method  600  is performed at a portable electronic device with a touch screen display (e.g., device  100 ,  FIG. 2 ). Some operations in method  600  may be combined and/or the order of some operations may be changed. In some embodiments, the contact/motion module  130  ( FIG. 1B ) detects user finger gestures on the touch screen display, and works with the mapping application  154  and data from the magnetometer  169  to control map display on the electronic device. 
     As described below, the method  600  provides an intuitive way to change map viewing modes, both in response to express user commands to change modes and in response to operations without express user commands to change modes (e.g., scrolling the map or searching). The method reduces the cognitive burden on a user when using a map application with multiple modes and multiple operations, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to interpret and use a mapping application more quickly and efficiently conserves power and increases the time between battery charges. 
     The device displays ( 602 ) a map on the display in an untracked mode of a mapping application (see, e.g., UI  500 A). The untracked mode comprises displaying the map on the display with an orientation that is independent of a current orientation of the portable electronic device. 
     The device receives ( 604 ) location information for the portable electronic device. For example, the device may receive information from GPS, nearby WiFi base stations, and/or nearby cell towers, as described in U.S. patent application Ser. Nos. 12/040,283, “Location Determination,” filed Feb. 29, 2008; 12/103,330, “Location Determination Using Formula,” filed Apr. 15, 2008; and 12/122,339, “Location Determination,” filed May 16, 2008. All of these applications are incorporated by reference herein in their entirety. 
     The device detects ( 606 ) a first activation of a mapping mode user interface element (e.g., user gesture  510  at mapping mode user interface element  502 ,  FIG. 5A ). The device may detect a finger gesture such as a tap gesture on the element. The mapping mode user interface element may be a physical button or a soft button displayed on the touch screen display. 
     In some embodiments, the mapping mode user interface element is a physical button located outside the touch screen display ( 608 ), such as home button  204  on portable multifunction device  100 , or any other suitable physical button. 
     In alternative embodiments, the mapping mode user interface element is a soft button on the touch screen display ( 610 ). In these embodiments the device may: display the mapping mode user interface element with a first appearance in the untracked mode of the mapping application; display the mapping mode user interface element with a second appearance in the tracked mode of the mapping application, wherein the second appearance is distinct from the first appearance; and display the mapping mode user interface element with a third appearance in the heading mode of the mapping application, wherein the third appearance is distinct from the first and second appearances (see, e.g., UI  500 A mapping mode user interface element  502 - 1 , UI  500 B mapping mode user interface element  500 - 2 , and UI  500 C mapping mode user interface element  500 - 3 ). 
     In some embodiments, the mapping mode user interface element may comprise a plurality of soft buttons on the touch screen display (not depicted). 
     In response to detecting the first activation of the mapping mode user interface element, the device enters ( 612 ) a tracked mode of the mapping application (see, e.g., UI  500 B). The tracked mode comprises the device displaying a current location icon  504  on the map that corresponds to a current location of the portable electronic device, and displaying the map on the display with an orientation that is independent of a current orientation of the portable electronic device (e.g., the orientation of the map is directed so that north is towards the top of the display). The tracked mode also includes the device maintaining the current location icon at a fixed or substantially fixed location on the touch screen display as the current location of the portable electronic device changes. For example, the device may keep the current location icon at or near the center of the displayed map. Here, a “substantially fixed” location means that the current location icon  504  will move no more than a predetermined number of pixels in any direction from the fixed location (e.g., 5, 10 or 20 pixels). 
     While in the tracked mode of the mapping application, the device detects ( 614 ) a second activation of the mapping mode user interface element (see, e.g., UI  500  B ( FIG. 5B ), user gesture  514  at mapping mode user interface element  502 ). 
     In response to detecting the second activation of the mapping mode user interface element, the device enters ( 616 ) a heading mode of the mapping application (e.g., UI  500 C,  FIG. 5C ). In the heading mode, the device: displays the current location icon; displays the map on the display with an orientation that corresponds to the current orientation of the portable electronic device determined with the magnetometer  169 ; and maintains the current location icon at the substantially fixed location on the touch screen display as the current location of the portable electronic device changes. In some embodiments, other components of the device, such as the accelerometer(s)  168  may also be used to determine the orientation of the device. 
     Displaying the map on the display with an orientation that corresponds to the current orientation of the portable electronic device may include configuring the map display to be oriented so that the heading to a point of interest is in a given direction on the display. For example, the heading may be towards one edge of the display, such as the top edge. 
     While in the heading mode of the mapping application, the device detects ( 618 ) a finger scrolling gesture on the touch screen display (e.g., user gesture  520  or  522 ,  FIG. 5D ). 
     In response to detecting the finger scrolling gesture on the touch screen display while in the heading mode, the device enters the tracked mode of the mapping application when the finger scrolling gesture moves the map less than a predefined amount on the touch screen display (e.g., 5, 10, or 20 pixels) (see, e.g., gesture  520  ( FIG. 5D ) and UI  500 E ( FIG. 5E ), which is in tracked mode). On the other hand, the device enters the untracked mode of the mapping application when the finger scrolling gesture moves the map greater than the predefined amount on the touch screen display ( 620 ) (see, e.g., gesture  522  ( FIG. 5D ) and UI  500 F ( FIG. 5F ), which is in untracked mode). 
     In some embodiments, when the device leaves the heading mode and enters the tracked mode because the finger scrolling gesture moved the map less than a predefined amount on the touch screen display, the device also returns the current location icon, which may have moved in response to the finger scrolling gesture, to the substantially fixed location on the touch screen display (e.g., icon  504 ,  FIG. 5E ). 
     In some embodiments, the device displays the current location icon with a heading indicator in the heading mode, and the device displays the current location icon without the heading indicator in the tracked mode ( 622 ). See, e.g., UI  500 D ( FIG. 5D ), which is in heading mode, where current location icon  504  is displayed with heading indicator  518  versus UI  500 B ( FIG. 5B ), which is in tracked mode, where current location icon  504  is displayed without a heading indicator. 
     In some embodiments, the heading indicator includes an arc that corresponds to the orientation of the device, and an angular range of the arc varies in accordance with an uncertainty in the orientation of the device ( 624 ). Additionally, in some embodiments, the device updates the angular range of the arc as a detected uncertainty in the orientation of the device changes ( 626 ). For example, see the discussion above concerning heading indicator  518 - 1  ( FIG. 5C ) versus heading indicator  518 - 2  ( FIG. 5D ). 
     In some embodiments, while in the heading mode of the mapping application, the device performs a search in response to a user&#39;s request, and in response, the device either enters the tracked mode of the mapping application when displaying one or more results of the search moves the map less than a predefined amount on the touch screen display (e.g., 5, 10, or 20 pixels), or the device enters the untracked mode of the mapping application when displaying one or more results of the search moves the map greater than the predefined amount on the touch screen display ( 628 ). For example, see the discussion above of UI  500 G-UI  500 I ( FIGS. 5G-5I ), where search result  540  was near current location icon  504  and the mapping application entered the tracked mode in UI  500 I, versus UI  500 J-UI  500 L ( FIGS. 5J-5L ), where search result  550 - 2  was far from current location icon  504  and the mapping application entered the untracked mode in UI  500 L. 
     In some embodiments, entering the tracked mode in operation  628  ( FIG. 6B ) also returns the current location icon, which may have moved in response to the finger scrolling gesture, to the substantially fixed location on the touch screen display. 
     In some embodiments, while in the tracked mode of the mapping application, the device performs a search, and in response, the device either remains in the tracked mode of the mapping application when displaying one or more results of the search moves the map on the display less than a predefined amount on the touch screen display (e.g., 5, 10, or pixels), or the device enters the untracked mode of the mapping application when displaying one or more results of the search moves the map on the display greater than the predefined amount on the touch screen display ( 630 ). For example, see the discussion above of UI  500 M-UI  500 O ( FIGS. 5M-5O ), where the search result is less than a predefined distance from the current location icon  504  so the mapping application remains in tracked mode, versus UI  500 O-UI  500 Q ( FIGS. 5O-5Q ), where the search results are greater than a predefined distance from the current location icon  504  so the mapping application enters untracked mode. 
     In some embodiments, while in the mapping application, the device performs a search (e.g., UI  500 P, search initiated by user gesture  560 ,  FIG. 5P ), receives one or more results of the search (e.g., UI  500 Q, search results  550 - 1  and  550 - 2 ,  FIG. 5Q ), detects a user selection of a search result from the one or more results of the search (e.g., user gesture  562  at search result  550 - 2 ,  FIG. 5Q ), enters the heading mode (e.g., UI  500 R,  FIG. 5R ) and displays the current location icon with a heading indicator in the heading mode (e.g., current location icon  504  and heading indicator  518 - 5 ,  FIG. 5R ). In these embodiments, the heading indicator includes an arc that corresponds to the orientation of the device, and an angular range of the arc varies in accordance with an orientation of the device with respect to the selected search result ( 632 ) (see, e.g., UI  500 R heading indicator  518 - 5  and UI  500 S heading indicator  518 - 6 ). In some of the embodiments, the device updates the angular range of the arc as the orientation of the device changes ( 634 ). In some embodiments, the device updates the angular range of the arc as the location of the device changes ( 636 ). For example, see the discussion above of heading indicator  518 - 5  and heading indicator  518 - 6  ( FIGS. 5R &amp; 5S ). 
     In some embodiments, while in the mapping application, the device performs a search (e.g., UI  500 P, search initiated by user gesture  560 ,  FIG. 5P ), receives one or more results of the search (e.g., UI  500 Q, search results  550 - 1  and  550 - 2 ,  FIG. 5Q ), detects a user selection of a search result from the one or more results of the search (e.g., user gesture  562  at search result  550 - 2 ,  FIG. 5Q ), enters the heading mode (e.g., UI  500 R,  FIG. 5R ) and displays the current location icon with a heading indicator in the heading mode (e.g., current location icon  504  and heading indicator  518 - 5 ,  FIG. 5R ). In these embodiments, the heading indicator includes an arc that corresponds to a current orientation of the device, and an angular range of the arc varies in accordance with the orientation of the device with respect to a route to the selected search result (e.g., a route from the current location of the device to the search result determined or suggested by the mapping application) ( 638 ). For example, see the arcs for heading indicator  518 - 5  ( FIG. 5R ) and heading indicator  518 - 6  ( FIG. 5S ), which vary as the location and/or orientation of the device changes with respect to route  564 . In some of the embodiments, the device updates the angular range of the arc as the orientation of the device changes ( 640 ). In some embodiments, the device updates the angular range of the arc as the location of the device changes ( 642 ). For example, the angular range of the arc in heading indicator  518 - 5  and heading indicator  518 - 6  vary as the location and/or orientation of the device changes with respect to route  564 . 
     In some embodiments, while in the heading mode of the mapping application, the device detects a third activation of the mapping mode button, and in response, the device enters the untracked mode of the mapping application ( 644 ) (e.g., user gesture  566  ( FIG. 5S ) and UI  500 T ( FIG. 5T ), which is in untracked mode). 
     In some embodiments, while in the heading mode of the mapping application, the device detects a third activation of the mapping mode button, and in response, the device enters the tracked mode of the mapping application ( 646 ) (not shown). 
     In some embodiments, the device detects an initial finger contact on the touch-sensitive surface, and the device detects that the finger contact remains on the touch-sensitive surface for a predefined amount of time (e.g., a “tap-and-hold” gesture where the finger contact remains stationary or substantially stationary on the touch-sensitive surface). In response to detecting the tap-and-hold gesture on the touch-sensitive surface, the device enters the heading mode. Conversely, in response to detecting the finger contact lifting off of the touch-sensitive surface, the device leaves the heading mode and returns to the previous map viewing mode (e.g., the tracked mode). This tap-and-hold gesture allows a user to quickly toggle to heading mode, regardless of what other map viewing mode is being displayed. 
     The steps in the information processing methods described above may be implemented by running one or more functional modules in information processing apparatus such as general purpose processors or application specific chips. These modules, combinations of these modules, and/or their combination with general hardware (e.g., as described above with respect to  FIGS. 1A &amp; 1B ) are all included within the scope of protection of the invention. 
     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 invention and its practical applications, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated.
