COMPUTER PROGRAM LISTING [0002Ì A portion of the disclosure of this patent document contains material which is subject to copyright protection. The copyright owner has no objection to facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent & Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever. [0003] Applicant has submitted herewith Computer Program Listings which are included as Appendix A, attached, BACKGROUND OF THE DISCLOSURE [0004] An API is a source code interface that a computer system or program library provides in order to support requests for services from a software application. An API is specified in terms of a programming language that can be interpretative or compled when an application is built, rather than an explicit low level description of how data is laid out in memory. The software that provides the functionality described by an A.PI is said to be an implementation of the APL [0005] Various devices such as electronic devices, computing systems, portable devices, and handheld devices have software applications. The API interfaces between the software applications and user interface software to provide a user of the device with certain features and operations. A user may desire certain operations such as scrolling, selecting, gesturing, and animating operations for a display of the device. APLNDC00027100 [0006] Scrolling is the act of sliding a directional (e.g., horizontal or vertical) presentation of content, such as text, drawings, or images, across a screen or display window. In a typical graphical user interface, scrolling is done with the help of a scrollbar or using keyboard shortcuts, often the arrow keys. Gesturing is a type of user input with two or more input points. Animating operations include changing content within a given time period. [0007] The various types of devices may have a limited display size, user interface, software, API interface and/or processing capability which limits the ease of use of the devices. User interfaces of devices implement APIs in order to provide requested functionality and features. These user interfaces can have difficulty interpreting the various types of user inputs and providing the intended functionality associated with the user mputs. -3- APLNDC00027101 SUMMARY OF THE DESCRIPTION [0008] At least certain embodiments of the present disclosure include one or more application programming interfaces in an environment with user interface software interacting with a software application. Various function calls or messages are transferred via the application programming interfaces between the user interface software and software applications. Example application programming interfaces transfer function calls to implement scrolling, gesturing, and animating operations for a device. [0009] At least certain embodiments of the present disclosure include an environment with user interface software interacting with a software application. A method for operating through an application programming interface (API) in this environment includes transferring a set bounce call. The method further includes setting at least one of maximum and minimum bounce values. The set bounce call causes a bounce of a scrolled region in an opposite direction of a scroll based on a region past an edge of the scrolled region being visible in a display region at the end of the scroll [0010] At least certain embodiments of the present disclosure include an environment with user interface software interacting with a software application. A method for operating through an application programming interface (API) in this environment includes transferring a rubberband call Rubberbanding a scrolled region within a display region occurs by a predetermined maximum displacement when the scrolled region exceeds a display edge. The method further includes transferring an edge rubberband call to set displacement values for at least one edge of the display (e.g., top and bottom edges, left and right edges). [0011] At least certain embodiments of the present disclosure include gesture operations for a display of a device. The gesture operations include performing a scaling transform such as a zoom in or zoom out in response to a user input having two or more input points. The gesture operations also include performing a rotation transform to rotate an image or view in response to a user input having two or more input points. [0012] At least certain embodiments of the present disclosure include a method for performing animations for a display of a device. The method includes starting at least one animation. The method further includes determining the progress of each animation. -4- APLNDC00027102 The method further includes completing each animation based on a single timer.

APLNDC00027106 DETAILED DESCRIPTION [0052] Various embodiments and aspects of the disclosure will be described with reference to details discussed below, and the accompanying drawings will illustrate the various embodiments. The following description and drawings are illustrative of the disclosure and are not to be construed as limiting the disclosure. Numerous specific details are described to provide a through understanding of various embodiments of the present disclosure. However, in certain instances, well-known or conventional details are not described in order to provide a concise discussion of embodiments of the present disclosure. (0053] Some portions of the detailed descriptions which follow are presented in terms of algorithms which include operations on data stored within a computer memory. An algorithm is generally a self-consistent sequence of operations leading to a desired result. The operations typically require or involve physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like. [0054] It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the following discussion, it is appreciated that throughout the description, discussions utilizing terms such as "processing" or "computing" or "calculating" or "determining" or "displaying" or the like, can refer to the action and processes of a data processing system, or similar electronic device, that manipulates and transforms data represented as physical (electronic) quantities within the system's registers and memories into other data similarly represented as physical quantities within the system's memories or registers or other such information storage, transmission or display devices. [0055] The present disclosure can relate to an apparatus for performing one or more of the operations described herein. This apparatus may be specially constructed for the required purposes, or it may comprise a general purpose computer selectively activated or -9APLNDC00027107 reconfigured by a computer program stored in the computer. Such a computer program may be stored in a machine (e.g. computer) readable storage medium, such as, but is not limited to, any type of disk including floppy disks, optical disks, CD-ROMs, and magnetic-optical disks, read-only memories (ROMs), random access memories (RAMs), erasable programmable ROMs (EPROMs), electrically erasable programmable ROMs (EEPROMs), flash memory, magnetic or optical cards, or any type of media suitable for storing electronic instructions, and each coupled to a bus. [0056] A machine-readable medium includes any mechanism for storing or transmitting information in a form readable by a machine (e.g., a computer). For example, a machinereadable medium includes read only memory ("ROM"); random access memory ("RAM"); magnetic disk storage media; optical storage media; flash memory devices; electrical, optical, acoustical or other form of propagated signals (e.g., carrier waves, infrared signals, digital signals, etc.); etc. [0057) At least certain embodiments of the present disclosure include one or application programming interfaces in an environment with user interface software interacting with a software application. Various function calls or messages are transferred via the application programming interfaces between the user interface software and software applications. Transferring the function calls or messages may include issuing, initiating, invoking or receiving the function calls or messages. Example application programming interfaces transfer function calls to implement scrolling, gesturing, and animating operations for a device having a display region. An API may also implement functions having parameters, variables, or pointers. An API may receive parameters as disclosed or other combinations of parameters. In addition to the APIs disclosed, other APIs individually or in combination can perform similar functionality as the disclosed APIs. [0058] The display region is a form of a window. A window is a display region which may not have a border and may be the entire display region or area of a display. In some embodiments, a display region may have at least one window and/or at least one view (e.g., web, text, or image content). A window may have at least one view. The methods, systems, and apparatuses disclosed can be implemented with display regions, windows, and/or views. - 0- APLNDC00027108 [0059] At least certain embodiments of the present disclosure include scrolling operations for scrolling a display of a device. The scrolling operations include bouncing a scrolled region in an opposite direction of a scroll when a scroll completes, rubberbanding a scrolled region by a predetermined maximum displacement when the scrolled region exceeds a display edge, and setting a scrolling angle that locks the scroll in a horizontal or vertical direction, (0060] At least certain embodiments of the present disclosure include gesture operations for a display of a device. The gesture operations include performing a scaling transform such as a zoom in or zoom out in response to a user input having two or more input points. The gesture operations also include performing a rotation transform to rotate an image or view in response to a user input having two or more input points. [0061] At least certain embodiments of the present disclosure include a method for performing animations for a display of a device. The method includes starting at least one animation. The method further includes determining the progress of each animation. The method further includes completing each animation based on a single timer. The single timer can be based on a redraw interval of the display hardware. (0062] At least certain embodiments of the disclosure may be part of a digital media player, such as a portable music and/or video media player, which may include a media processing system to present the media, a storage device to store the media and may further include a radio frequency (RF) transceiver (e.g., an RF transceiver for a cellular telephone) coupled with an antenna system and the media processing system. In certain embodiments, media stored on a remote storage device may be transmitted to the media player through the RF transceiver. The media may be, for example, one or more of music or other audio, still pictures, or motion pictures. [0063] The portable media player may include a media selection device, such as a click wheel input device on an iPod® or iPod Nano® media player from Apple Computer, Inc. of Cupertino, CA, a touch screen input device, pushbutton device, movable pointing input device or other input device. The media selection device may be used to select the media stored on the storage device and/or the remote storage device. The portable media player may, in at least certain embodiments, include a display device which is coupled to the media processing system to display titles or other indicators of media being selected -11- APLNDC00027109 through the input device and being presented, either through a speaker or earphone(s), or on the display device, or on both display device and a speaker or earphone(s). In some embodiments, the display device and input device are integrated while in other embodiments the display device and input device are separate devices. Examples of a portable media player are described in published U.S. patent application numbers 2003/0095096 and 2004/0224638, both of which are incorporated by reference. [0064] Embodiments of the disclosure described herein may be part of other types of data processing systems, such as, for example, entertainment systems or personal digital assistants (PDAs), or general purpose computer systems, or special purpose computer systems, or an embedded device within another device, or cellular telephones which do not include media players, or multi touch tablet devices, or other multi touch devices, or devices which combine aspects or functions of these devices (e.g., a media player, such as an iPod®, combined with a PDA, an entertainment system, and a cellular telephone in one device). In this disclosure, electronic devices and consumer devices are types of devices. [0065] FIG. 1 is flow chart of a method for responding to a user input of a device. The method 100 includes receiving a user input at block 102. The user input may be in the form of an input key, button, wheel, touch, or other means for interacting with the device. The method 100 further includes creating an event object in response to the user input at block 104. The method 100 further includes determining whether the event object invokes a scroll or gesture operation at block 106. For example, a single touch that drags a distance across a display of the device may be interpreted as a scroll operation. In one embodiment, a two or more finger touch of the display may be interpreted as a gesture operation. In certain embodiments, determining whether the event object invokes a scroll or gesture operation is based on receiving a drag user input for a certain time period. The method 100 further includes issuing at least one scroll or gesture call based on invoking the scroll or gesture operation at block 108. The method 100 further includes responding to at least one scroll call, if issued, by scrolling a window having a view (e.g., web, text, or image content) associated with the event object based on an amount of a scroll with the scroll stopped at a predetermined position in relation to the user input at block I10. For example, an input may end at a certain position on a display of the device. The scrolling -12- APLNDC00027110 may continue until reaching a predetermined position in relation to the last input received from the user. The method 100 further includes responding to at least one gesture call, if issued, by changing a view associated with the event object based on receiving a plurality of input points in the form of the user input at block i 12. [0066] In certain embodiments of the present disclosure, scroll operations include attaching scroll indicators to a content edge of a display. Alternatively, the scroll indicators can be attached to the display edge. In some embodiments, user input in the form of a mouse/finger down causes the scroll indicators to be displayed on the display edge, content edge, or window edge of the scrolled region. If a mouse/finger up is then detected, the scroll indicators are faded out from the display region, content edge, or window edge of the scrolled region. [0067] In certain embodiments of the present disclosure, gesture operations include responding to at least one gesture call, if issued, by rotating a view associated with the event object based on receiving a plurality of input points in the form of the user input. Gesture operations may also include scaling a view associated with the event object by zoomog m or zooming out based on receiving the user input. [0068) In some embodiments, a device includes a display region having multiple views or windows. Each window may have a multiple views including superviews and subviews. It is necessary to determine which window, view, superview, or subview is contacted by a user input in the form of a mouse up, mouse down, or drag, etc. An API can set various modes for making this determination. In one embodiment, a pass mode sends mouse down, mouse up, and drag inputs to the nearest subview. In another embodiment, an intercept on drag mode sends a drag input to the superview while mouse up and down inputs are sent to the subview. In another embodiment, an intercept mode sends all drag, mouse up and down inputs to the superview. The superview may be scroller software operating as a subclass of a view software. The subview may be view software operating as a subclass of the user interface software, (0069] FIG. 2 illustrates details of an application programming interface in flow chart form according to certain teachings of the present disclosure. The application programming ínterface operates in an environment with user interface software interacting with a software application in order to provide a bounce operation. The -13- APLNDC00027111 method 200 for providing a bounce operation includes transferring a set bounce call at block 202. The method 200 further includes setting at least one of maximum and minimum bounce values at block 204. The minimum and maximum bounce values may be associated with at least one edge of a window that has received a user input. The method 200 further includes causing a bounce of a scrolled region in an opposite direction of a scroll based on a region past the scrolled region being visible in a display region at the end of the scroll at block 206. The scrolled region may be a content region. [0070) In certain embodiments of the present disclosure, transferring the set bounce call is either one of issuing, initiating, invoking or receiving the set bounce call. [0071] FIG. 3 illustrates details of an application programming interface in flow chart form according to certain teachings of the present disclosure. The application programming interface operates m an environment with user interface software interacting with a software application in order to provide a rubberband operation. The method 300 for providing a rubberband operation includes transferring a rubberband call to cause rubberbanding a scrolled region displayed within a display at block 302. The method 300 further includes transferring an edge rubberband call to set displacement values for at least one edge of the display at block 304. In some embodiments, the displacement values are set for top and bottom edges, left and right edges, or all edges. [0072) Rubberbanding a scrolled region according to the method 300 occurs by a predetermined maximum displacement value when the scrolled region exceeds a display edge of a display of a device based on the scroll. If a user scrolls content of the display making a region past the edge of the content visible in the display, then the displacement value limits the maximum amount for the region outside the content. At the end of the scroll, the content slides back making the region outside of the content no longer visible on the display. [0073] In certain embodiments of the present disclosure, transferring the rubberband call is either one of issuing, initiating, invoking or receiving the rubberband call [0074] Figure 4 is a schematic diagram illustrating an embodiment of user interface of a portable electronic device 400 having a touch-sensitive display 408. The display 408 may include a window 410. The window 410 may include one or more displayed objects, such as information objects 412-1 to 412-4. In an exemplary embodiment, the -14- APLNDC00027112 information objects 412 may correspond to contact information for one or more individuals in a list of items. The displayed objects may be moved in response to detecting or determining movement 414 of a point of contact with the display, such as that associated with one or more digits 416 of a user (which are not drawn to scale in Figure 4). In some embodiments, movement of the displayed objects may be accelerated in response to detecting or determining accelerated movement of the point of contact. While embodiment 400 includes one window 410, in other embodiments there may be two or more display windows. In addition, while embodiment 400 illustrates movement 414 in a particular direction, in other embodiments movement of the displayed objects may be in response to movement 414 in one or more other directions, or in response to a scalar (i.e., a determined or detected movement independent of the direction). [0075] Figures 5A-5C illustrate the scrolling of a list of items on a device to a terminus of the list, at which point one or more displayed items at the end of the list smoothly bounce off the end of the display, reverse direction, and then optionally come to a stop. Figure 5A is a schematic diagram illustrating an embodiment of user interface of a portable electronic device 400 having a touch-sensitive display. One or more displayed objects, such as information object 412-1 may be a distance 512-1 from a terminus 514 of the list of items which is an edge of a scrolled region and may be moving with a velocity 510-1 while the list is being scrolled. Note that the terminus 514 is a virtual boundary associated with the displayed objects, as opposed to a physical boundary associated with the window 410 and/or the display 408. As illustrated in Figure 5B, when the one or more displayed objects, such as the information object 412-1, reach or intersect with the terminus 514, the movement corresponding to the scrolling may stop, i.e., the scrolling velocity may be zero at an instant in time. As illustrated in Figure SC, the one or more displayed objects, such as the information 412-1, may subsequently reverse direction. At a time after the intersection with the terminus 514, the information object 412-1 may have velocity 510-2 and may be a distance 512-2 from the terminus 514. In some embodiments, the magnitude of velocity 510-2 may be less than the magnitude of velocíty 510-1 when the distance 512-2 equals the distance 512-1, i.e., the motion of the one or more displayed objects is damped after the scrolling list reaches and "bounces" at its tenninus. -15- APLNDC00027113 [0076] In at least some embodiments of the present disclosure, the method 200 performs the bounce operations described in FIGS. 5A-SC. The bounce call transferred at block 202 determines whether a bounce operation is enabled. The maximum and minimum bounces values determine the amount of bouncing of the scrolled region in an opposite direction of the scroll. [0077] Figures 6A-6D illustrate the scrolling of a list of items to a terminus of the list, at which point an area beyond the terminus is displayed and the list is then scrolled in an opposite direction until the area beyond the terminus is no longer displayed, in accordance with some embodiments. The rubberband operation of method 300 is illustrated in the example of Figures 6A-6D with the listed items being email messages. Figures 6A-6D illustrate an exemplary user interface 3500A for managing an inbox in accordance with some embodiments. An analogous user interface may be used to display and manage other mailboxes (e.g., drafts, sent, trash, personal, etc.). In addition, other types of lists are possible, including but not limited to lists of instant message conversations, favorite phone numbers, contact information, labels, email folders, email addresses, physical addresses, ringtones, or album names. [0078] If the list of emails fills more than the allotted screen area, the user may scroll through the emails using vertically upward and/or vertically downward swipe gestures on the touch screen. In the example of Figure 6A, a portion of a list of emails is displayed in the screen area, including a top displayed email 3530 from Bruce Walker and a bottom displayed email 3532 from Kim Brook, A user performs a vertically downward swipe gesture 3514 to scroll toward the top of the list. The vertically downward gesture 3514 need not be exactly vertical; a substantially vertical gesture is sufficient. In some embodiments, a gesture wíthin a predetermined angle of being perfectly vertical results in vertical scrolling. [0079) As a result of detecting the vertically downward gesture 3514, in Figure 6B the displayed emails have shifted down, such that the previous bottom displayed email 3532 from Kim Brook is no longer displayed, the previous top displayed email 3530 from Bruce Walker is now second from the top, and the email 3534 from Aaron Jones, which was not displayed in Figure 6A, is now displayed at the top of the list. -16- APLNDC00027114 (0080] In this example, the email 3534 from Aaron Jones is the first email in the list and thus is the terrninus of the list. Upon reaching this email 3534, in response to continued detection of the vertically downward gesture 3514, an area 3536 (Figure 6C) above the first email 3534 (i.e., beyond the terminus of the list) is displayed. In some embodiments, the area displayed beyond the terminus of the list is visually indistinct from the background of the list. In Figure 6C, both the area 3536 and the background of the emails (e.g., emails 3534 and 3530) are white and thus are visually indistinct. [0081] Once vertically downward gesture 3514 is complete, such that a corresponding object is no longer detected on or near the touch screen display, the list is scrolled in an opposite direction until the area 3536 is no longer displayed. Figure 6D illustrates the result of this scrolling in the opposite direction, the email 3534 from Aaron Jones is now displayed at the top of the screen area allotted to the list and the area 3536 is not displayed. [0082] In the example of Figures 6A-6D, a vertically downward gesture resulted in display of an area beyond the first item in the list. As described in Figure 3, the values for the predetermined maximum displacement (e.g., display of an area beyond the first item in the list) are set at block 304 for top and bottom edges or at block 306 for all edges of the window. [0083) Similarly, a vertically upward gesture may result in display of an area beyond the last item of the list, if the vertically upward gesture continues once the list has been scrolled to the last item. The last item may be considered a terminus of the list, similar to the first item. As discussed above, the gesture need not be exactly vertical to result in vertical scrolling; a gesture within a predefined range of angles from perfectly vertical is sufficient. (0084] FIG. 7 illustrates details of an application programming interface in flow chart form according to certain teachings of the present disclosure. The application programming interface operates in an environment with user interface software interacting with a software application in order to provide a directional scrollmg operation. The method 700 for operating through an application programming interface (API) includes transfe1Ting a directional scroll angle call to determine if directional scrolling is enabled at block 702. The method 700 further includes transferring a - 7APLNDC00027115 directional scroll angle call to set a scroll angle for locking the scrolling in at least one of a vertical or a horizontal direction at block 704. The method 700 further includes locking the scrolling in the horizontal direction if a user input forms an angle with a horizontal direction that is less than or equal to a first scroll angle at block 706. The method 700 further includes locking the scrolling in the vertical direction if a user input forms an angle with the vertical direction that is less than or equal to a second scroll angle at block 708. [0085] In certain embodiments, a user input in the form of a drag forms an angle with the horizontal direction that is less than the first scroll angle. In this case, the user presumably intends to scroll in the horizontal direction. The scrolling will be locked in the horizontal direction until the user input exceeds the first scroll angle. A second scroll angle may be used for locking the user input in the vertical direction. The second scroll angle may be set equal to the first scroll angle. [0086] FIG. 8 illustrates first and second scroll angles for locking a scroll of a display of a device in a horizontal or vertical direction. The horizontal direction 802 and vertical direction 804 are in reference to a window or a display of a device. As discussed in the method 700, a user input such as a drag movement forming an angle with the horizontal direction 802 less than or equal to the first scrolling angle 806 or 808 will lock the user input in the horizontal direction. In a similar manner, a user input forming an angle with the vertical direction 810 less than or equal to the second scrolling angle 810 or 812 will lock the user input in the vertical direction. The first and second scrolling angles may be set at the same angle or at different angles as well. For example, the first and second scrolling angles may be set at 25 degrees. A user input less than or equal to 25 degrees with respect to the horizontal or vertical direction will lock the scrolling in the appropriate direction. [0087) In some embodiments, the horizontal and vertical lockíng angles can be determined in part by the aspect of the content. For example, content in the form of a tall page may receive a larger vertical locking angle compared to the horizontal locking angle. [0088] FIG. 9 illustrates details of an application programming interface in flow chart form according to certain teachings of the present disclosure. The application -18- APLNDC00027116 programming interface operates in an environment with user interface software interacting with a software application in order to provide a deceleration scroll operation. The method 900 for providing the deceleration scroll operation includes transferring a deceleration scroll call to set a deceleration factor for a drag user input at block 902. The method 900 further includes slowing the scroll to a stop based on the speed of the drag user input and the deceleration factor at block 904. [0089] In certain embodiments, a user input in the form of a drag invokes a scroll operation for a certain time period. The user input has a certain speed. The scroll of the scrolled region of a window or a display region of a display of a device will be stopped after the user input stops by applying a deceleration factor to the speed of the user input during the drag movement. [0090] FIG. 10 illustrates details of an application programming interface in flow chart form according to certain teachings of the present disclosure. The application programming interface operates in an environment with user interface software interacting with a software application in order to provide a scroll hysteresis operation. The method 1000 for providing the scroll hysteresis operation includes transferring a scroll hysteresis call to determine whether a user input invokes a scroll at block 1002. The method 1000 further includes setting a hysteresis value for determining whether a user input invokes a scroll at block 1004. [0091] In certain embodiments, a user input in the form of a drag over a certain distance across a display or window within a display of a device invokes a scroll operation. The hysteresis value determines the certain distance which the user input must drag across the display or window prior to invoking a scroll operation. A user input that does not drag the certain predetermined distance will not invoke a scroll operation and may be considered a mouse up or down input or other type of input. [0092) FIG. 11 illustrates details of an application programming interface in flow chart form according to certain teachings of the present disclosure. The application programming interface operates in an environment with user interface software interacting with a software application in order to attach a scroll indicator to a scroll region edge or a window edge of a device. In some embodiments, the scroll region edge is associated with a content edge. The window or display edge may be associated with -19- APLNDC00027117 the edge of a display region. The method 1100 for providing the scroll indicator includes transferring a scroll indicator call to determine whether at least one scroll indicator attaches to an edge of a scroll region or a window edge at block 1102. A scroll indicator may be displayed on any display edge, window edge or scroll region edge. The method I100 further includes optionally attaching at least one scroll indicator to the edge of the scroll region based on the scroll indicator call at block l104. Alternatively, the method l100 further includes optionally attaching at least one scroll indicator to the window edge of the view based on the scroll indicator call at block 1106. [0093] In some embodiments, the operations of method 1100 can be altered, modified, combined, or deleted. For example, block 1104 can be deleted. Likewise, block 1106 can be deleted from the method 1100. Alternatively, the order of block 1104 and block 1106 can be switched. Other methods having various operations that have been disclosed within the present disclosure can also be altered, modified, rearranged, collapsed, combined, or deleted. [0094] In certain embodiments of the present disclosure, transferring the scroll indicator call is either one of issuing, initiating, invoking or receiving the scroll indicator call. For example, the user interface software (e.g., software kit or library) may receive the scroll indicator call from the software application. (0095] FIG. 12 illustrates details of an application programming interface in flow chart form according to certain teachings of the present disclosure. The application programming interface operates in an environment with user interface software interacting with a software application in order to determine if an inadvertent user input contacts a view of a display of a device. The method 1200 includes transferring an inadvertent user input call to determine whether the user input was inadvertent at block 1202. The method 1200 further includes ignoring the inadvertent user input based on the determination of the inadvertent user input call at block 1204. In one embodiment, the inadvertent user input call comprises a thumb detection call to determine whether the user input was an inadvertent thumb. [0096] In certain embodiments of the present disclosure, transferring the inadvertent user input call is either one of issuing, initiating, invoking or receiving the inadvertent user input call. -20- APLNDC00027118 (0097] A gesture API provides an interface between an application and user software in order to handle gesturing. Gesturing may include scaling, rotating, or other changes to a view, window, or display. A mask may merely permit certain changes while limiting or not permitting other changes. Events of all kinds come into the application via a graphics framework. They are enqueued, collaleced if necessary and dispatched. If the events are system level events (e.g., application should suspend, device orientation has changed, etc) they are routed to the application having an instance of a class of the user interface software. If the events are hand events based on a user input, the events are routed to the window they occurred over. The window then routes these events to the appropriate control by calling the instance's mouse and gesture methods. The control that receives a mouse down or mouse entered function will continue to get all future calls until the hand is lifted. If a second finger is detected, the gesture methods or functions are invoked. These functions may include start, change, and end gesture calls. The control that receives start gesture call will be sent all future change gesture calls until the gesture ends. [0098] FIG. 13 illustrates details of an application programming interface in flow chart form according to certain teachings of the present disclosure. The application programming interface operates in an environment with user interface software interacting with a software application in order to provide a gesture operation. The method 1300 for providing the gesture operation includes transferring a handle gesture event call at block 1302. The method 1300 further includes transferring a gesture change call in response to the handle gesture event call at block 1304. [0099] In certain embodiments, a user input in the form of two or more points is received by a display of a device. A multi-touch driver of the device receives the user input and packages the event into an event object. A window server receives the event object and determines whether the event object is a gesture event object. If the window server determines that a gesture event object has been received, then user interface software issues or transfers the handle gesture call at block 1302 to a software application associated with the view. The software application confirms that a gesture event has been received and passes the handle gesture call to a library of the user interface software. The window server also associates the gesture event object with the view that -21APLNDC00027119 received the user input. The library responds by transferring a gesture change call in response to the handle gesture event call at block 1304. [00100] In one embodiment, a window or view associated with the user input receives the change call in order to perforn the gesture event. The user software that provides the view receives a gesture start event call, a gesture changed event call, a zoom to scale setting for the view, and a gesture end call. The gesture calls receive an input of a gesture event which may be base event having a type such as a hand event, keyboard event, system event, etc. A delegate associated with the application receives a start gesture call, gesture did change call, and gesture did finish call. The user software is dynamically linking into the application during the run time of the gesture process. [00101] In some embodiments, the gesture changed function call contains the following information about the gesture: the number of fingers currently down; the number of fingers initially down; the rotation of the hand; the scale of the hand; the translation of the hand; the position of the inner and outermost fingers; and the pressure of the first finger. In other embodiments, more information about each finger down may be included as follows, the stage of the finger (just touch down, fully pressed, lifting off, etc); the position of the finger; the proximity of the finger (how hard you're touching); the orientation of the finger (what angle the ovoid is at); the length of the major and minor axis; the velocity of the finger; and the eccentricity of the finger's ovoid. -22APLNDC00027120 [00102] A gesture event object may be a chord event object having a chord count (e.g., number of fingers contacted the view or display), a chord start event, a chord change event, and a chord end event. A chord change event may include a scaling or rotation transform. [00103] FIG. 14 illustrates details of an application programming interface in flow chart form according to certain teachings of the present disclosure. The application programming interface operates in an environment with user interface software interacting with a software application in order to provide a scaling transform of a display region, window, or view of a display of a device. The method 1400 for providing the scaling transform includes transferring a scaling transform call to determine a scaling transform for a view associated with a user input having a plurality of input points at block 1402. The method 1400 further includes transferring a scaling gesture start call at block 1404. The method 1400 further includes transferring a scaling gesture progress call at block 1406. The method 1200 further includes transferring a scaling gesture end call at block 1408. [00104] In certain embodiments, a user input in the form of two or more input points (e.g., fingers) moves together or apart to invoke a gesture event that performs a scaling transform on the view associated with the user input. A scale transform includes a minimum and maximum scale factor. FIG. 15 illustrates a display 1502 of a device having a scaling transform of a view. The view 1504 (e.g., web, text, or image content) has a first scale factor. A user input (e.g., two fingers moving apart) associated with the view 1504 is interpreted as a gesture event to zoom out from view 1504 to view 1508 having a second scale factor that exceeds the maximum scale factor of the view 1516. A snapback flag determines whether the zoom out can proceed past the maximum scale factor to view 1508 prior to snapping back to the maximum scale factor associated with view 1516. [00105] FIG. 16A illustrates a display 1604 of a device having a first scaling factor of a view 1616. A user input (e.g., two fingers 1608 and 1610 moving together) associated with the view 1614 is interpreted as a gesture event to zoom in from view 1614 to view 1664 having a second scale factor as illustrated in FIG. 16B. The dashed regions 1602 and 1650 represent the total area of the content with the only content being -23- APLNDC00027121 displayed in the display area 1604 and 1652. In performing the scaling transform from FIG. 16A to FIG. 16B, the center of the gesture event, center 1612 for FIG. 16A and center 1660 for FIG. 16B, remains in the same position with respect to the display 1604. The scroll indicator 1606 shrinks to become scroll indicator 1654 during the transform to indicate that a smaller portion of the total content 1650 is being displayed on display 1604 as a result of the zoom in operation. The dashed region 1650 is larger than the dashed region 1602 to represent that a larger portion of content is not being displayed on display 1652 in FIG. 16B as a result of the zoom in operation. [00106] In at least some embodiments of the present disclosure, a user desires to change a view 1670 from a scale factor of 2x to a scale factor of lx as illustrated in FIG. 16C. A first set of user inputs 1672 and 1674 that move to the second set of user inputs 1676 and 1678 will decrease the scale factor from 2x to lx. It may be desirable for the user to scale from 2x to lx without having to move the user inputs a large distance across the view 1670. In an environment with user interface software interacting with a software application, a gesture scaling transform flag may be set in order to determine a scaling transform for a view associated with a user input having a plurality of input points. The scaling transform flag scales either from a current scale factor to a minimum scale factor or from the current scale factor to a maximum scale factor. For example, a flag may be set at the position associated with a 1.5x scale factor and a third set of user inputs 1680 and 1682. A user desiring to change the scale factor from 2x to lx would only have to move his fingers, the user inputs, from the first set 1672 and 1674 to the third set 1680 and 1682 if the gesture scaling transform flag has been set at a scale factor of 1.5x. [00107] FIG. 17 illustrates details of an application programming interface in flow chart form according to certain teachings of the present disclosure. The application programming interface operates in an environment with user interface software interacting with a software application in order to provide a rotation transform of a view, window, or display region of a display of a device. The method 1700 for providing the rotation transform includes transferring a rotation transform call to determine a rotation transform for a view associated with a user input having a plurality of input points at block 1702. The method 1700 further includes transferring a rotation gesture start call at -24- APLNDC00027122 block 1704. The method 1700 further includes transferring a scaling gesture progress call at block 1706. The method 1700 further includes transferring a scaling gesture end call at block 1708. [00108] In certain embodiments, a user input in the form of two or more input points rotates to invoke a gesture event that performs a rotation transform on the view associated with the user input. The rotation transform includes a minimum and maximum degree of rotation for associated minimum and maximum rotation views. The user input may temporarily rotate a view past a maximum degree of rotation prior to the view snapping back to the maximum degree of rotation. [00109] FIG. 18 illustrates details of an application programming interface in flow chart form according to certain teachings of the present disclosure. The application programming interface operates in an environment with user interface software interacting with a software application in order to notify a delegate of at least one animation associated with a display region, window, or view of a display of a device. A delay in the animation may be specified by the API. Also, multiple animations may be assigned priority by the APL The method 1800 for notifying the delegate includes determining whether any animation occurs at block 1802. The method 1800 further includes checking the progress of an animation at block 1804. If progress has occurred, then the next state (e.g., position, opacity, or transform) of the animation can be calculated at block 1806. If progress has completed at block 1806, then at block 1808 it is determined whether the view associated with the completed animation is associated with a delegate. If so, a delegate call is transferred to notify the delegate of the animation for the view at block 1810. The delegate operating under the control of the software application can change other views in response to the view being modified by the ammation. [00110] In certain embodiments, software invokes an animation that performs a scaling transform on the view associated with the user input. A display may include numerous views. The view being increased in size by the scaling transform may obstruct other views in which case the other views may need to be reduced in size. Alternatively, the view being decreased in size by the scaling transform may create additional area for other views to increase in size. -25- APLNDC00027123 [00111] FIG. 19 is flow chart of a method for animating a display region, windows, or views displayed on a display of a device. The method 1900 includes starting at least two animations at block 1902. The method 1900 further includes determining the progress of each animation at block 1904. The method 1900 further includes completing each animation based on a single timer at block 1906. [00112] In certain embodiments of the present disclosure, the single timer includes a timer based on a redraw interval which is a time period between the display of a current frame and a next frame of the display of the device. In this case, changes in animation are updated to the display during the redraw interval in order to display the changes during the next frame of the display. The progress of each animation may be calculated periodically or based upon a progress call. [00113] The method 1900 may further include determining whether each animation is associated with a delegate. The delegate is then notified of the animation. Other views not associated with an animation may be changed depending on the software application controlling the delegate. [00114] FIG. 20 is flow chart of a method for animating a display region, windows, or views displayed on a display of a device. The method 2000 includes providing a single animation timer at block 2002. The method 2000 further includes animating a plurality of animations with the single animation timer at block 2004. For example, a single timer may control all animations which occur simultaneously. The animations may include a transform, a frame, and an opacity animation. A animation transform may include a scaling or rotation transform. A frame animation may include resizing of a frame. An opacity animation changes the opacity from opaque to transparent or vice versa. [00115] FIG. 21 illustrates details of an application programming interface in flow chart form according to certain teachings of the present disclosure. The application programming interface operates in an environment with user interface software interacting with multiple software applications or processes in order to synchronize animations associated with multiple views or windows of a display of a device. The method 2100 for synchronizing the animations includes setting attributes of views independently with each view being associated with a process at block 2102. For -26- APLNDC00027124 example, an attribute or property of a view may include a position, size, opacity, etc. An animation alters one or more attributes from a first state to a second state. The method 2100 further includes transferring a synchronization call to synchronize animations for the multiple views of the display at block 2l04. The synchronization call may include input parameters or arguments such as an identification of the synchronization of the processes and a list of the processes that are requesting animation of the multiple views. In one embodiment, the synchronization call includes the identification and the number of processes that are requesting animation. In one embodiment, each application or process sends a synchronization call at different times. The method 2100 further includes transferring a synchronization confirmation message when a synchronization flag is enabled at block 2106. The synchronization flag can be enabled when the processes to be synchronized have each sent messages to a window server operating the user interface software. The method 2100 further includes updating the attributes of the views from a first state to a second state independently at block 2108. In one embodiment, the window server receives the updated attributes from each process at different times. The method 2100 further includes transferring a start animation call to draw the requested animations when both processes have updated attributes associated with the second state at block 2110. [00116] In some embodiments, a first data structure or layer tree represents a hierarchy of layers that correspond to the views or windows of the processes. A second data structure or render tree represents a similar copy of the layer tree. However, the render tree is not updated until the independent processes have completed their separate animations. At this time, the render tree updates and redraws the screen with the new ammations. [00117] FIG. 22A and 22B illustrate synchronizing the resizing of views or windows of a display of a device. For example, a window 2210 associated with a first process with a size attribute may mcrease in size by changing from a first state, window 2210 in FIG. 22A, to a second state, window 2210 in FIG. 22B. At approximately the same time, a second window 2220 may decrease in size in proportion to the increase in size of the first window 2210. The method 2100 provides synchronization of the resizing of the windows 2210 and 2220 illustrated in FIG. 22A and 22B. The animations in -27APLNDC00027125 changing from the first state to the second state may occur incrementally and occur with the synchronization of method 2100. [00118] FIG. 23 illustrates a method for switching ownership of a view of an application displayed on a display of a data processing device. The method 2300 includes constructing a data structure having a hierarchy of layers with a layer being associated with a view and owning the view at block 2302. The layers may be content, windows, video, images, text, media, or any other type of object for user interface of the application. The method 2300 further includes removing the layer from the data structure at block 2304. The method 2300 further includes switching ownership of the view from the layer to the view at block 2306. [00119] In some embodiments, each layer from the data structure is associated with a view. The layer associated with the view sends a delegate function call to the view in order to generate content provided by the view. A first pointer reference points from the layer to the view. A second pointer reference points from the view to the layer. The number of references pointing to an object such as the view is defined as the retained count of the object. The view may receive notification that the layer will be removed from the data structure. Removing the layer from the data structure may occur based on the view associated with the layer being removed from the display of the device. When the layer is removed from the data structure or layer tree the pointer from the layer to the view will be removed. The view will have a retained count of zero and be deallocated or removed from memory if the ownership of the view is not reversed. The view will have a retained count of at least one if ownership is reversed. [00120] FIG. 24 illustrates a method for memory management of a view of an application displayed on a display of a device. The method 2400 includes constructing a data structure having a hierarchy of layers with at least one layer being associated with the view at block 2402. The method 2400 further includes storing the data structure in memory at block 2404. The method 2400 further includes maintaining a retained count of the number of references to the view from other objects at block 2406. The method 2400 further includes deallocating the view from memory if the retained count is zero at block 2408. As discussed above, the retained count of the view will be decremented if the layer is removed from the data structure. Removing the layer from the data structure -28APLNDC00027126 may occur based on the view associated with the layer being removed from the display of the device. [00121] FIG. 25A and 25B illustrate a data structure having a hierarchy of layers with a layer being associated with a view. The data structure includes layers 2502, 2504, and 2506. Layer 2506 is associated with the view 2510. The layer 2506 associated with the 2510 view sends a delegate call to the view in order to generate content provided by the view. A first pointer reference 2508 points from the layer 2506 to the view 2510. A second pointer reference 2512 points from the view 2510 to the layer 2506. A third pointer reference 2532 may point from user interface (UI) controller 2530 to the view 2510. The UI controller 2530 may control operations associated with the view 2510 such as scrolling the view 2510 in response to a user input. The view 2510 in FIG. 25A has a retained count of two based on the pointer references 2508 and 2532. (00122] If the layer 2506 is removed from the data structure as illustrated in FIG. 25B, then the pointer 2508 is removed. View 2510 will have a lower retained count as illustrated in FIG. 25B. If view 2510 has a retained count of zero, then the memory storing the view 2510 will be deallocated. [00123] FIG. 26 illustrates a method for compositing media and non-media content of user interface for display on a device. The method 2600 includes constructing a data structure having a hierarchy of layers associated with the user interface of the device at block 2602. The method 2600 further includes determining whether each layer of the data structure is associated with media or non-media content at block 2604. The data structure or layer tree is traversed in order to determine whether each of the layers of the data structure is associated with media or non-media content. The method 2600 further includes detaching a layer associated with media content from the data structure at block 2606. The method 2600 further includes storing media content in a first memory location at block 2606. The method 2600 further includes storing non-media content in a second memory location at block 2608. The method 2600 further includes compositing the media and non-media content for display on the device at block 2610. [00124] In some embodiments, compositing the media and non-media content includes retrieving the media content from the first memory location, retrieving the nonmedia content from the second memory location, and scanning the media and non-media -29- APLNDC00027127 content directly to the display. The memory location can be any type of memory located in cache, main memory, a graphics processing unit, or other location within a device. The media content may include video, video plug-in, audio, image, or other time varying media. The media content may be in the form of a YUV model with the Y representing a luminance component (the brightness) and U and V representing chrominance (color) components. The media content may be scanned to the display at a rate of substantially twenty to forty frames per second. The media content may be scaled prior to being scanned to the display of the device. (00125] The non-media content may include content, views, and images that do not require frequent updating. The non-media content may be in the form of a RGB model which is an additive model in which red, green, and blue (often used in additive light models) are combined m vanous ways to reproduce other colors. The non-media content may be scanned to the display at a slower rate compared to the media content. [00126] FIG. 27 illustrates a data structure or layer tree having a hierarchy of layers. The layers can be associated with media and non-media content. For example, layer 2704 is associated with media content 2706 such as a video. Layer 2710 is associated with non-media content 2712 which may be user interface view for the video. Layers 2720, 2730, and 2740 are associated with non-media content 2722, 2732, and 2742, respectively, that forms the components of the non-media content 2712. The method 2600 will determine whether each layer of the data structure is associated with media or non-content. Any layers associated with media content such as layer 2704 will be removed from the data structure and processed in a separate memory location. [00127] In some embodiments, the methods, systems, and apparatuses of the present disclosure can be implemented in various devices including electronic devices, consumer devices, data processing devices, desktop computers, portable computers, wireless devices, cellular devices, tablet devices, handheld devices, multi touch devices, multi touch data processing devices, any combination of these devices, or other like devices. Figures 4-6 and 28-33 illustrate examples of a few of these devices. [00128] FIG. 28 illustrates a device 2800 according to one embodiment of the disclosure.

[00129] The display device 2834 is shown positioned at an upper portion of the housing 2832, and the input device 2836 is shown positioned at a lower portion of the housing 2832. The antenna 2842 is shown extending from the housing 2832 at an upper portion of the housing 2832. The speaker 2838 is also shown at an upper portion of the housing 2832 above the display device 2834. The microphone 2840 is shown at a lower portion of the housing 2832, below the input device 3286. It will be appreciated that the speaker 2838 and microphone 2840 can be positioned at any location on the housing, but are typically positioned in accordance with a user's ear and mouth, respectively. [00130) The display device 2834 may be, for example, a liquid crystal display (LCD) which does not include the ability to accept inputs or a touch input screen which also includes an LCD. The input device 2836 may include, for example, buttons, switches, dials, sliders, keys or keypad, navigation pad, touch pad, touch screen, and the like. Any well-known speaker, microphone and antenna can be used for speaker 2838, microphone 2840 and antenna 2842, respectively. [00131] The data acquired from the proximity sensor 2844 and the accelerometer 2846 can be combined together, or used alone, to gather information about the user's activities. The data from the proximity sensor 2844, the accelerometer 2846 or both can be used, for example, to activate/deactivate a display backlight, initiate commands, make selections, control scrolling, gesturing, animating or other movement in a display, control input device settings, or to make other changes to one or more settings of the device, n certain embodiments of the present disclosure, the device 2800 can be used to implement at least some of the methods discussed in the present disclosure.

The device 2950 may have a form factor which is small enough that it fits within the hand of a normal adult and is light enough that it can be carried in one hand by an adult. It will be appreciated that the term "portable" means the device can be easily held in an adult user's hands (one or both); for example, a laptop computer and an iPod are portable devices. [00133] In one embodiment, the display/input device 2954 may include a multi- point touch input screen in addition to being a display, such as an LCD. In one embodiment, the multi-point touch screen is a capacitive sensing medium configured to detect multiple touches (e.g., blobs on the display from a user's face or multiple fingers concurrently touching or nearly touching the display) or near touches (e.g., blobs on the display) that occur at the same time and at distinct locations in the plane of the touch panel and to produce distinct signals representative of the location of the touches on the plane of the touch panel for each of the multiple touches. [00134] In certain embodiments of the present disclosure, the device 2800 can be used to implement at least some of the methods discussed in the present disclosure. [00135] FIGS. 30A and 30B illustrate a device 3070 according to one embodiment of the disclosure. The device 3070 may be a cellular telephone which includes a hinge 3087 that couples a display housing 3089 to a keypad housing 3091. The hinge 3087 allows a user to open and close the cellular telephone so that it can be placed in at least one of two different configurations shown in FIGS. 30A and 30B. In one particular embodiment, the hinge 3087 may rotatably couple the display housing to the keypad housing. In particular, a user can open the cellular telephone to place it in the open configuration shown in FIG. 30A and can close the cellular telephone to place it in the closed configuration shown in FIG. 30B. The keypad housing 3091 may include a keypad 3095 which receives inputs (e.g. telephone number inputs or other alphanumeric -32- APLNDC00027130 inputs) from a user and a microphone 3097 which receives voice input from the user. The display housing 3089 may include, on its interior surface, a display 3093 (e.g. an LCD) and a speaker 3098 and a proximity sensor 3084; on its exterior surface, the display housing 3089 may include a speaker 3096, a temperature sensor 3094, a display 3088 (e.g. another LCD), an ambient light sensor 3092, and a proximity sensor 3084A.

In one implementation of an embodiment, the device 3070 may be a cellular telephone integrated with a media player which plays MP3 files, such as MP3 music files. [00137] Each of the devices shown in FIGS. 4, 5A, 5B, 5C, 6A, 6B, 6C, 6D, 28, 29, 30A and 30B may be a wireless communication device, such as a cellular telephone, and may include a plurality of components which provide a capability for wireless communication. FIG. 31 shows an embodiment of a wireless device 3070 which includes the capability for wireless commumcation. The wireless device 3070 may be included in any one of the devices shown in FIGS. 4, 5A, 5B, 5C, 6A, 6B, 6C, 6D, 28, 29, 30A and 30B, although alternative embodiments of those devices of FIGS. 4, 5A, 5B, 5C, 6A, 6B, 6C, 6D, 28, 29, 30A and 30B may include more or fewer components than the Wireless device 3070. [00138] Wireless device 3070 may include an antenna system 3101. Wireless device 3070 may also include a digital and/or analog radio frequency (RF) transceiver 3102, coupled to the antenna system 3101, to transmit and/or receive voice, digital data and/or media signals through antenna system 3101. [00139] Wireless device 3070 may also include a digital processing system 3103 to control the digital RF transceiver and to manage the voice, digital data and/or media signals. Digital processing system 3103 may be a general purpose processing device, such as a microprocessor or controller for example. Digital processing system 3103 may also be a special purpose processing device, such as an ASIC (application specific -33- APLNDC00027131 integrated circuit), FPGA (field-programmable gate array) or DSP (digital signal processor). Digital processing system 3103 may also include other devices, as are known in the art, to interface with other components of wireless device 3070.
