Description

P100101 1 Regulation 3.2 AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Invention Title: Editing interface The following statement is a full description of this invention, including the best method of performing it known to us: EDITING INTERFACE TECHNICAL FIELD [0011 The disclosed embodiments relate to graphical user interfaces. BACKGROUND [0021 As portable devices become more compact, and the amount of information to be processed and stored increases, it has become a significant challenge to design a user interface that allows users to easily interact with the device. This is unfortunate since the user interface is the gateway through which users receive not only content but also responses to user actions or behaviors, including user attempts to access a device's features or tools. Some portable electronic devices (e.g., mobile phones) have resorted to adding more pushbuttons, overloading the functions of pushbuttons, or using complex menu systems to allow a user to access, store and manipulate functions or data. These conventional user interfaces often result in complicated key sequences and menu hierarchies that must be memorized by the user. [0031 Many conventional user interfaces, such as those that include physical pushbuttons, are also inflexible. This is unfortunate because the inflexibility may prevent a user interface from being configured and/or adapted by either an application running on the portable device or by users. When coupled with the time consuming requirement to memorize multiple key sequences and/or menu hierarchies, such inflexibility is frustrating to many users. [004] Some conventional user interfaces can be configured by users, thereby allowing at least partial customization. Unfortunately, the process of modifying such conventional user interfaces is often as cumbersome and complicated as the use of the conventional user interface itself. In particular, the required behaviors during configuration of such conventional user interfaces are often counter intuitive and the corresponding indicators guiding user actions are often difficult to understand. These challenges are often a source of additional frustration for users. SUMMARY [0051 A portable electronic device displays icons (e.g., graphical objects) in one or more regions of a user interface of a touch-sensitive display, and detects user input specifying - 1 an exchange of positions of icons in the user interface. In some aspects, the respective positions of two icons in a user interface can be selected to exchange positions in the one or more regions of the user interface, and one or both icons can change their visual appearance to indicate their selection status. [0061 In some implementations, a method includes: displaying a first icon in a first position in a touch-sensitive display; displaying a second icon in a second position of the touch-sensitive display; receiving first touch input specifying selection of the first icon; responsive to the first touch input, modifying the visual appearance of the first icon; receiving second touch input indicating movement of the first icon to within proximity of the second icon; and responsive to the second touch input, modifying the visual appearance of the second icon. 10071 In some implementations, a method includes: displaying an icon in a first position of a touch-sensitive display; receiving first touch input specifying selection of the icon; responsive to the first touch input, modifying the visual appearance of the icon; receiving second touch input indicating movement of the icon to within proximity of a second position in the user interface; and responsive to the second touch input, modifying the visual appearance of the second position. [0081 In some implementations, a method includes: displaying a first icon in a first page of a touch-sensitive display; receiving first touch input specifying selection of the first icon; responsive to the first touch input, modifying the visual appearance of the first icon; receiving second touch input indicating movement of the first icon to within proximity of an edge of the touch sensitive display; responsive to the second touch input, displaying a second page of the touch-sensitive display, the second page including a second icon; receiving third touch input indicating movement of the first icon to within proximity of the second icon; and responsive to the third touch input, modifying the visual appearance of the second icon.

DESCRIPTION OF EMBODIMENTS [0201 Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail so as not to unnecessarily obscure aspects of the embodiments. Overview of the Interface Reconfiguration Mode [0211 Attention is directed towards embodiments of portable electronic devices, including portable communications devices, that have graphical user interfaces (GUIs). The portable devices include an interface reconfiguration mode. In response to a user initiating the interface reconfiguration mode, positions of one or more icons displayed on the portable device may be varied about respective average positions. The varying of the positions of the one or more icons may include animating the one or more icons to simulate floating of the one or more icons on a surface corresponding to a surface of a display in the portable device. The display may be a touch-sensitive display, which responds to physical contact by a stylus or one or more fingers at one or more contact points. While the following embodiments may -3be equally applied to other types of displays, a touch-sensitive display is used as an illustrative example. [022] The varying of the positions of the one or more icons may intuitively indicate to the user that the positions of the one or more icons may be reconfigured by the user. The user may modify, adapt and/or reconfigure the positions of the one or more icons. In embodiments where the portable device includes a touch-sensitive display, the user may make contact with the touch-sensitive display proximate to a respective icon at a first position. Upon making contact with the touch-sensitive display, the respective icon may cease varying its position. The user may drag the respective icon to a second position. Upon breaking contact with the touch-sensitive display, the respective icon may resume varying its position. In some embodiments, the display may include two regions. During the interface reconfiguration mode, positions of one or more icons displayed in the first region may be varied while positions of one or more icons displayed in the second region may be stationary. [0231 The user may similarly modify, adapt and/or reconfigure the positions of additional icons during the interface reconfiguration mode. When the user has completed these changes (at least for the time being), he or she may terminate the interface reconfiguration mode. In response to this user action, the portable device may return to a normal mode of operation and the varying of the displayed positions of the one or more icons will cease. [0241 The user may initiate or terminate the interface reconfiguration process by selecting one or more appropriate physical buttons on the portable device, by a gesture (such as making contact and swiping one or more fingers across the touch-sensitive display) and/or by selecting one or more soft buttons (such as one or more icons that are displayed on the touch-sensitive display). As used herein, a gesture is a motion of the object/appendage making contact with the touch screen display surface. In some embodiments, the interface reconfiguration process terminates a pre-defined time after the interface reconfiguration process is initiated, i.e., there is a time out. [025] The one or more icons displayed on the portable device may be graphical objects. In some embodiments, the one or more icons may be widgets, which are combinations of states and procedures that constitute on-screen representations of controls that may be manipulated by the user, such as bars, buttons and text boxes. In an exemplary embodiment, the one or more icons correspond to application programs (email, browser, address book, etc.) that may be selected by the user by contacting the touch-sensitive display proximate to an icon of interest. -4- [026] Figure 1 is a flow diagram of one embodiment of a position adjustment process 100 for a portable electronic device. While the position adjustment process 100 described below includes a number of operations that appear to occur in a specific order, it should be apparent that the process 100 can include more or fewer operations, which can be executed serially or in parallel (e.g., using parallel processors or a multi-threading environment), an order of two or more operations may be changed and/or two or more operations may be combined into a single operation. [0271 In the position adjustment process 100, a plurality of icons are displayed in a GUI in a touch-sensitive display (110). A first predefined user action that initiates an interface reconfiguration process is detected (112). Exemplary predefined user actions include selecting a physical button on the portable device, making a predefined gesture on the touch screen display surface, or selecting a soft button. Position(s) of one or more of the plurality of displayed icons are varied (114). A point of contact with the touch-sensitive display at a first position of a respective icon is detected (116). Movement of the point of contact to a second position is detected (118). Movement of the respective icon to the second position is displayed and the respective icon is displayed at the second position (120). 10281 If a second predefined user action that terminates the interface reconfiguration process is detected (122-yes), the position(s) of the one or more icons is fixed (124). Exemplary predefined user actions include selecting or deselecting a physical button on the portable device, making another predefined gesture on the touch screen display surface, or selecting or deselecting a soft button. The fixed position(s) may correspond to a respective average position(s) for the one or more icons. If a second pre-defined user action that terminates the interface reconfiguration process is not detected (122-no), the process may continue when a point of contact proximate to the same or another icon is detected (116). [029] Figure 2A is an illustration of one embodiment of a portable electronic device 200 responsive to touch input for adjustment of the position of one or more icons. The portable electronic device 200 includes a touch-sensitive display with a GUI 210. The display surface is transparent to allow various graphical objects to be displayed to the user (e.g., widgets). In some embodiments, the GUI 210 is divided into multiple sections or windows. For example, a region 212 of GUI 210 may include a tray 216 for holding icons or graphical objects 222 representing functions that are frequently used by the user (e.g., video, weather, schedule, game, music, etc.) and a tray 214 for holding icons or graphical objects 220 representing functions that are used less frequently by the user (e.g., mail, address book, browser, etc.). The GUI 210 may also include graphical objects corresponding to high-level -5functions of the portable electronic device 200. For example, various objects and/or images may be presented and changed in GUI 210 by pressing a menu button 240. In embodiments that include a mobile phone, dedicated graphical objects can be presented in GUI 210 representing traditional voice and data service operations (e.g., hold, clear, etc.). [0301 The user may interact with the portable communications device 200 by making contact with the display surface with GUI 210 using a stylus, a finger 218 (not drawn to scale in Figure 2) or more than one finger. For example, the user may make contact with the display surface at a position of one of the icons 222 (direct contact), thereby activating the function or application program corresponding to that icon. In some embodiments, the icon 222 is activated when the user makes contact at the position of the icon and then breaks contact (for example, a tapping gesture). In some embodiments, the contact with the display surface used to activate the icon may not be at the position of the icon 222. Instead, contact may be proximate to the icon 222 (indirect contact). The latter technique is similar to "hot spots" used with Web pages and other computer user interfaces. [0311 Figures 2B-D show the portable electronic device 200 during the interface reconfiguration mode. After the interface reconfiguration mode is initiated, the display of one or more of the icons 222 in the tray 216 is modified from the previous stationary positions to time-varying positions. As noted previously, the display may include animating one or more of the icons 222 to simulate floating of one or more of the icons 222 on a surface corresponding to the display surface. For example, the animated varying of the positions of one or more of the icons 222 during the interface reconfiguration mode may resemble that of a hockey puck in an air hockey game. The displayed position(s) of a respective icon in the icons 222 may be varied in a region 224 centered on the average position of the respective icon. [0321 While Figure 213-2D illustrates movement of one or more of the icons 222 in the tray 216, in other embodiments positions of one or more of the icons 220 in another region of GUI 210, such as tray 214, may be varied separately or in addition to those of one or more of the icons 222 in tray 216. [0331 The time-varying position(s) of one or more of the icons 222 intuitively indicate to the user that the positions of one or more of the icons 222 may be modified. This is illustrated in Figures 2C-D, which show the portable electronic device 200 during the interface reconfiguration mode. The user makes contact, either direct or indirect, with one of the icons that is moving at a position 226 and moves the point of contact across the display surface with GUI 210. The contact and the motion are detected by the portable electronic -6device 200. As a consequence, the displayed icon, in this example corresponding to a game, is moved accordingly. 10341 As shown in Figure 2D, the user moves the game icon to position 228 and breaks contact with the display surface. The game icon is now displayed at the position 228. While the displayed position of the game icon is shown as stationary in Figure 2D, in some embodiments the position of the game icon may be varied once the user breaks contact with the display surface. In some embodiments, only icons displayed in one or more subsections of the GUI 210 are displayed with a varying position during the interface reconfiguration mode. Thus, if the game icon had been dragged to another position in the tray 222, it may be displayed with a varying position after the user breaks contact with the display. 10351 Figure 2D also illustrates the optional displacement of the browser icon to position 230. The browser icon was displaced from its initial position 228 to its new position 230 due to at least partial overlap with the game icon, i.e., when the portable electronic device 200 determined that the user positioned the game icon over the browser icon, the displayed position of the browser icon was changed. [0361 In other embodiments, an icon may be evicted or removed from the tray 214 when an additional icon, such as the browser icon, is added to the tray 214. For example, the tray 214 may be configured to accommodate a finite number of icons, such as 4 icons. If an additional icon is added to the tray 214, a nearest icon to the additional icon or an icon that at least partially overlaps the additional icon may be evicted or removed from the tray 214. [0371 Figure 2E illustrates the portable electronic device 200 after the interface reconfiguration mode has been terminated or has terminated (due to a time out). The icons in GUI 210 have stationary positions. The game icon and the browser icon are displayed in their new positions in the tray 214. 10381 The animated effects during the interface reconfiguration mode, such as the varying position(s) of one or more of the icons 222, may be in accordance with corresponding equations of motion for one or more of the icons in a plane substantially coincident with the display surface with GUI 210. The equations of motion may have a coefficient of friction less than a threshold allowing the simulation and/or animation of floating or sliding of one or more of the icons. The equation of motion for the respective icon may have a non-zero initial velocity, a non-zero angular velocity, and/or a restoring force about the respective average position of the respective icon such that the position of the respective icon oscillates in the region 224 (Figure 2D) substantially centered on the respective average position of the respective icon. -7- [0391 In some embodiments, the position of the respective icon may be varied during the interface reconfiguration mode in such a way that the respective icon rotates about the respective average position of the respective icon while maintaining a fixed orientation with respect to the GUI 210 and the portable electronic device 200. This is illustrated in Figures 3A and 3B, which show the portable electronic device 200 during the interface reconfiguration mode. In this example, the position of the video icon 222 in tray 216 is varied in such a way that it maintains a fixed orientation in region 224. This may make it easier for the user to determine the function of the respective icon during the interface reconfiguration mode. Portable Electronic Device Architecture 10401 Attention is now directed towards embodiments of the portable electronic device architecture. Figure 4 is a block diagram of one embodiment of portable electronic device. A portable electronic device 400 generally includes one or more computer-readable mediums 402, a processing system 404, an Input/Output (I/O) subsystem 406, radio frequency (RF) circuitry 408 and audio circuitry 410. These components may be coupled by one or more communication buses or signal lines 403. The device 400 can be any portable electronic device, including but not limited to a handheld computer, a tablet computer, a mobile phone, a media player, personal digital assistant (PDA) and the like, including a combination of two or more of these items. 1041] It should be apparent that the architecture shown in Figure 4 is only one example of an architecture for the portable electronic device 400, and that the device 400 could have more or fewer components than shown, or a different configuration of components. The various components shown in Figure 4 can 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. The RF circuitry 408 is used to send and receive information over a wireless link or network to one or more other devices and includes well-known circuitry for performing this function, 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, memory, etc. In some embodiments, the RF circuitry 408 is capable of establishing and maintaining communications with other devices using one or more communications protocols, including but not limited to time division multiple access (TDMA), code division multiple access (CDMA), global system for mobile communications (GSM), Enhanced Data GSM Environment (EDGE), wideband code division multiple access (W-CDMA), Wi-Fi (such as IEEE 802.1 la, IEEE 802.11 b, IEEE -8- 802.11 g and/or IEEE 802.11 n), Bluetooth, Wi-MAX, voice over Internet Protocol (VoIP), a protocol for email, instant messaging, and/or a short message service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document. 10421 The RF circuitry 408 and the audio circuitry 410 are coupled to the processing system 404 via the peripherals interface 416. The interface 416 includes various known components for establishing and maintaining communication between peripherals and the processing system 404. The audio circuitry 410 is coupled to an audio speaker 450 and a microphone 452 and includes known circuitry for processing voice signals received from interface 416 to enable a user to communicate in real-time with other users. In some embodiments, the audio circuitry 410 includes a headphone jack (not shown). Voice and data information received by the RF circuitry 408 and the audio circuitry 410 (e.g., in speech recognition or voice command applications) is sent to one or more processors 418 via the peripherals interface 416. The one or more processors 418 are configurable to process various data formats for one or more applications programs 430 stored on the medium 402. 10431 Note that the term "data" includes but is not limited to text, graphics, Web pages, JAVA applets, widgets, emails, instant messages, voice, digital images or video, widgets, MP3s, etc., which can be used by one or more applications programs 430 stored on the medium 402 (e.g., Web browser, email, etc.). In some embodiments, the device 400 is capable of uploading and downloading various data from the Internet over a wireless network or an external port 436, such as files, songs, digital images, videos, emails, widgets, instant messages and the like. 1044] The peripherals interface 416 couples the input and output peripherals of the device to the processor 418 and the computer-readable medium 402. The one or more processors 418 communicate with the one or more computer-readable mediums 402 via a controller 420. The computer-readable medium 402 can be any device or medium that can store code and/or data for use by the one or more processors 418. The medium 402 can include a memory hierarchy, including but not limited to cache, main memory and secondary memory. The memory hierarchy can be implemented using any combination of RAM (e.g., SRAM, DRAM, DDRAM), ROM, FLASH, magnetic and/or optical storage devices, such as disk drives, magnetic tape, CDs (compact disks) and DVDs (digital video discs). The medium 402 may also include a transmission medium for carrying information-bearing signals indicative of computer instructions or data (with or without a carrier wave upon which the signals are modulated). For example, the transmission medium may include a -9communications network, including but not limited to the Internet (also referred to as the World Wide Web), intranet(s), Local Area Networks (LANs), Wide Local Area Networks (WLANs), Storage Area Networks (SANs), Metropolitan Area Networks (MAN) and the like. 10451 The one or more processors 418 run various software components stored in the medium 402 to perform various functions for the device 400. In some embodiments, the software components include an operating system 422, a communication module (or set of instructions) 424, a contact/motion module (or set of instructions) 426, a graphics module (or set of instructions) 428, one or more applications (or set of instructions) 430, a timer module (or set of instructions) 438 and a reconfiguration module (or set of instructions) 440. [0461 The operating system 422 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various procedures, sets of instructions, 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. [047] The communication module 424 facilitates communication with other devices over one or more external ports 436 or via RF circuitry 408 and includes various software components for handling data received from the RF circuitry 408 and/or the external port 436. The external port 436 (e.g., USB, FireWire

TM

, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). 10481 The graphics module 428 includes various known software components for rendering, animating and displaying graphical objects on a display surface of a touch sensitive display system 412. Note that the term "graphical object" includes any object that can be displayed to a user, including without limitation text, web pages, icons, digital images, animations and the like. [0491 The one or more applications 430 can include any applications installed on the device 400, including without limitation, a browser, address book, contact list, email, instant messaging, word processing, keyboard emulation, widgets, JAVA-enabled applications, encryption, digital rights management, voice recognition, voice replication, location determination capability (such as that provided by the global positioning system (GPS)), a music player (which plays back recorded music stored in one or more files, such as MP3 or AAC files), etc. - 10- [050] In some embodiments, the device 400 may include the functionality of an MP3 player, such as an iPod (trademark of Apple Computer, Inc.). The device 400 may, therefore, include a 36-pin connector that is compatible with the iPod. In some embodiments, the device 400 may include one or more optional optical sensors (not shown), such as CMOS or CCD image sensors, for use in imaging applications. 10511 The contact/motion module 426 includes various software components for performing various tasks associated with the touch-sensitive display system 412, as previously described with respect to the embodiments in Figures 1-3. [0521 The timer module 438 is a software timer used with the interface reconfiguration process 100 (Figure 1). The timer module 438 can also be implemented in hardware. [0531 The reconfiguration module 440 may include an icon effects module (or a set of instructions) 442. The icon effects module 442 may include animation for the icons during the interface reconfiguration mode. In some embodiments, the icon effects module 442 may be included in the graphics module 428. [0541 The I/O subsystem 406 is coupled to the touch-sensitive display system 412 and one or more other physical control devices 414 (e.g., pushbuttons, switches, dials, LEDs, etc.) for controlling or performing various functions, such as power control, speaker volume control, ring tone loudness, keyboard input, scrolling, hold, menu, screen lock, clearing and ending communications and the like. The touch-sensitive display 412 communicates with the processing system 404 via the touch sensitive screen controller 432, which includes various components for processing user input (e.g., scanning hardware). The one or more other input controllers 434 receives/sends electrical signals from/to the other input or control devices 414. The other input/control devices 414 may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, sticks, and so forth. 10551 The touch-sensitive display 412 displays visual output to the user in a GUI. The visual output may include text, graphics, video, and any combination thereof. Some or all of the visual output may correspond to user-interface objects. The touch-sensitive display 412 may also accept input from the user based on haptic and/or tactile contact. The touch sensitive display 412 forms a touch-sensitive surface that accepts user input. The touch sensitive display 412 and the touch screen controller 432 (along with any associated modules and/or sets of instructions in the medium 402) detects contact (and any movement or release of the contact) on the touch-sensitive display 412 and converts the detected contact into interaction with user-interface objects, such as one or more soft keys, that are displayed on - 11 the touch screen when the contact occurs. In an exemplary embodiment, a point of contact between the touch-sensitive display 412 and the user corresponds to one or more digits of the user. The touch-sensitive display 412 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-sensitive display 412 and touch screen controller 432 may detect contact and any movement or release thereof using any of a plurality of touch sensitivity technologies, 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 the touch-sensitive display 412. [056] The touch-sensitive display may be analogous to the multi-touch sensitive tablets described in the following U.S. Patents: 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. However, the touch screen 126 displays visual output from the portable device, whereas touch sensitive tablets do not provide visual output. The touch-sensitive display 412 may have a resolution in excess of 100 dpi. In an exemplary embodiment, the touch-sensitive display 412 may have a resolution of approximately 168 dpi. The user may make contact with the touch-sensitive display 412 using any suitable object or appendage, such as a stylus, pen, finger, and so forth. 10571 In some embodiments, in addition to the touch screen, the device 400 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-sensitive display 412 or an extension of the touch-sensitive surface formed by the touch-sensitive display 412. [0581 The device 400 also includes a power system 444 for powering the various hardware components. The power system 444 can 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 typically associated with the generation, management and distribution of power in portable devices. 10591 In some embodiments, the peripherals interface 416, the one or more processors 418, and the memory controller 420 may be implemented on a single chip, such as the processing system 404. In some other embodiments, they may be implemented on separate chips. - 12 - Repositioning Icons [0601 Figure 5 is a block diagram of one example of a portable electronic device illustrating the repositioning of user interface elements (hereinafter referred to generally as "icons") in one or more regions of a user interface. In some implementations, one or more icons 502 can be repositioned by a user in a user interface 501 of a device (e.g., portable electronic device 500). In some implementations, a user can initiate an interface reconfiguration mode on the device 500. While in the interface reconfiguration mode, one or more of the icons 502 can be repositioned in the user interface 501 by the user. While in the interface reconfiguration mode, the user can touch one of the icons 502 and drag it to a desired new position on the user interface 501. For example, the user can drag an icon 508 selected from the icons 502 to an empty or occupied position in a tray 504, in which case an occupying icon 512 will be replaced by the icon 508. [0611 In some implementations, when the device 500 enters an interface reconfiguration mode, the icons 502 that are movable are displayed at a scaled size (e.g., scaled up by 150%). When the device 500 exits the interface reconfiguration mode, the icons 502 are displayed at their original size. Alternatively, an icon that the user touches and moves while the device 500 is in the interface reconfiguration mode (as opposed to all of the movable icons 502) is displayed at a scaled size to indicate its selection status to the user. When the touching ceases the icon can be displayed at its original size again. In other implementations, the selected icon can change color, animate, flash, change shape, display text or otherwise modify its visual appearance. In addition to changing its visual appearance, the device 500 can emit an audible sound (e.g., tone, succession of tones) to indicate its selection status. In some implementations, the repositioning of icons can be enabled without entering a reconfiguration mode on the device 500. [0621 In some implementations, icons can be displayed in multiple "pages" and the user can navigate between the pages, an example of which is described in U.S. Patent Application No. 11/850,005, titled "Application Menu User Interface," filed September 4, 2007, which patent application is incorporated by reference herein in its entirety. In such implementations, the user can drag an icon from a first page of icons to a second page of icons. For example, a user can touch and drag an icon in the first page and drag the icon toward the edge of the user interface 501. When the icon is dragged to within a predetermined distance from the edge of the user interface 501 (e.g., 5 pixels), the first page of icons displayed on the user interface 501 can be replaced with a second page of icons. The - 13 user can then position the dragged icon within the second page, which is now displayed on the user interface 501. [0631 In some implementations, a user can drag a first icon toward a second icon in the user interface 501 to exchange the positions of the two icons in the user interface 501. In this case, the second icon can be displayed with additional graphical effects to indicate its selection status for exchange with, or replacement by, the first icon. For example, the second icon can be displayed with an oscillating visual intensity, from a high intensity (e.g., bright) to a low intensity (e.g., dim) and back to high intensity. As another example, the second icon can be displayed with a "glow" effect. In some implementations, the additional graphical effects applied to the second icon can be triggered when the first icon is moved to within a predetermined distance of the second icon. 10641 Figure 5 illustrates an example mobile device 500 with a first icon 508 moved into proximity of a second icon 512 located in tray 504. The proximity can be x pixels (e.g., 1 pixel) from the periphery of the icon 512 as indicated by a boundary 510. When the first icon 508 is moved such that any part of the first icon 508 is within the region enclosed by the boundary 510, the second icon 512 can be displayed with additional graphical effects, such as a glow effect or an oscillating intensity, for example. In some implementations, the additional graphical effects are not displayed when the user releases the touch on the first icon 508 over the second icon 512, and thus having them exchange positions, or when the user moves the first icon 508 outside of the region enclosed by the boundary 510. In some implementations, the first icon 508 can be repositioned into an empty position in the tray 504. In such implementations, the outline 510 can be displayed to indicate the empty position within the tray 504 where the first icon 508 will be positioned when the user releases the touch. Other visual feedback can be provided to indicate an empty or available position in the tray 504, such as changing the color or opacity of the position in the tray 504 or applying a graphic, pattern overlay or animated object at the position in the tray 504. Process for Exchanging Icon Positions [0651 Figure 6 is a flow diagram of an example process 600 for exchanging icons of a user interface. In some implementations, the process 600 includes displaying a first icon in a first position of a touch-sensitive display (602). The touch-sensitive display can be a multi touch sensitive display which is responsive to finger gestures as well as touch. A second icon is displayed in, or associated with, a second position of the touch-sensitive display (604). In some implementations, the first and second icon positions can be in different regions of a user interface. For example, the first region can be used to display a first set of icons and the - 14 second region can be a tray, dock, menu bar, a second page or any other user interface element capable of displaying a second set of icons in a manner that visually distinguishes or otherwise prominently displays the second set of icons from the first set of icons. The second set of icons can include icons that are frequently used icons or icons that have a common property or attribute (e.g.. application icons). [0661 The process 600 receives a first touch input specifying selection of the first icon (606). The touch can be with a finger or styles. Responsive to the first touch input, the visual appearance of the first icon is modified (608). Some examples of modifying the visual appearance of the first icon include but are not limited to: scaling, changing color, vibrating, bouncing, displaying text, animating, etc. [0671 The process 600 receives a second touch input indicating movement of the first icon to within proximity of the second icon (610). The movement can be the dragging of the first icon across the display. In some implementations, proximity to the second icon occurs when a (transparent or non-transparent) boundary line at least partially surrounding the second icon is touched or crossed by the first icon as a result of, or in response to, the movement. [0681 Responsive to the second touch input, the visual appearance of the second icon can be modified (612). Some examples of modifying the second icon include but are not limited to: scaling, applying a glowing effect, changing color, vibrating, bouncing, animating, etc. [0691 The foregoing descriptions of specific embodiments of the present invention are presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Rather, it should be appreciated that 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. - 15 -
