## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Patent Application No. 60/772,160 filed on Feb. 10, 2006 entitled “Improved User-Interface and Architecture for Portable Processing Device,” which is herein incorporated by reference.


FIELD OF THE INVENTION
The present invention generally relates to a user interface and a portable processing device architecture for improving user experience and more specifically to a system and method that provides a user with an easy to use, intuitive interface.
BACKGROUND OF THE INVENTION
Existing portable processing devices have interfaces that do not readily permit multi-tasking scenarios. Often users want to utilize a single finger to control the display and application especially in small handheld devices. Existing processing devices, such as, for example, a PDA/voice communication device, may have an interface that does not have one-handed usability and thus may require a user to use both hands when navigating or using applications. Often, one is in a particular application and to exit that application and enter another application there are many steps that need to occur that slow down the process of getting a particular task done. This is because most devices will require the user to exit out of a working application and open a new application to do a separate task, such as look up a contact in a contacts record after having been in a calendar or phone application. Thus, the use of such devices may be awkward for users who are always on the go.
What is needed in the art is an improved interface which simplifies and improves the user experience for navigating applications and interacting with a computing device, such as, for example, a small handheld device.
Therefore, there is a need for an improved interface for interacting with the computing device.
These and other advantages may be provided by various embodiments of the present invention.
SUMMARY OF THE INVENTION

Detailed descriptions of well-known networks, communication systems, computers, terminals, devices, components, techniques, data and network protocols, software products and systems, operating systems, development interfaces, and hardware are omitted so as not to obscure the description of the present invention.
FIG. 1 illustrates a block diagram of an exemplary processing device 100 which may be used to implement systems and methods consistent with the principles of the invention. Processing device 100 may include a bus 110, a processor 120, a memory 130, a read only memory (ROM) 140, a storage device 150, an input device 160, an output device 170, and a communication interface 180. Bus 110 may permit communication among the components of processing device 100.
Processor 120 may include at least one conventional processor or microprocessor that interprets and executes instructions. Memory 130 may be a random access memory (RAM) or another type of dynamic storage device that stores information and instructions for execution by processor 120. Memory 130 may also store temporary variables or other intermediate information used during execution of instructions by processor 120. ROM 140 may include a conventional ROM device or another type of static storage device that stores static information and instructions for processor 120. Storage device 150 may include any type of media, such as, for example, magnetic or optical recording media and its corresponding drive.
Input device 160 may include one or more conventional mechanisms that permit a user to input information to system 200, such as a keyboard, a pen, a voice recognition device, a microphone, a headset, a digitizer, etc. Output device 170 may include one or more conventional mechanisms that output information to the user, including a display, one or more speakers, a headset, or a medium, such as a memory, or a magnetic or optical disk and a corresponding disk drive. Communication interface 180 may include any transceiver-like mechanism that enables processing device 100 to communicate via a network, such as, for example, a computer network or a telephone network. For example, communication interface 180 may include a modem, or an Ethernet interface for communicating via a local area network (LAN). Alternatively, communication interface 180 may include other mechanisms for communicating with other devices and/or systems via wired, wireless or optical connections.
Processing device 100 may perform such functions in response to processor 120 executing sequences of instructions contained in a computer-readable medium, such as, for example, memory 130, a magnetic disk, or an optical disk. Such instructions may be read into memory 130 from another computer-readable medium, such as storage device 150, or from a separate device via communication interface 180.
FIG. 2 illustrates an implementation of exemplary processing device 100 consistent with the principles of the invention. Processing device 100 may include a keyboard 202 and a display 210. The keyboard may further include a group of keys representing numbers, letters, and/or symbols, as well as navigation keys 204, a panel key 206, and a clear/exit (CLR) key 208. In one implementation, the navigation keys may include five keys, a center key, right and left keys, and up and down keys. The use of the keys, in implementations consistent with the principles of the invention, will become obvious from the following descriptions.
FIG. 3 illustrates an exemplary display 300 for processing device 100. Exemplary display 300 may include an indicator or icon for each application that may be executed on processing device 100. A thick line surrounding an indicator for APPI may indicate that a current focus of display 300 is APPI. So, if a user presses an execute key, then the application or function associated with the current focus will be processed by the computing device and present the user with further information or an application associated with the current focus. In other implementations consistent with the principles of the invention, a current focus may be indicated by other means, such as, for example, reverse video, use of a particular color to highlight the current focus, blinking, as well as other means. Any action or command that is input by a user may pertain to the current focus, which in this example is APPI. Icons 302, 304 of display 300 may indicate currently executing applications. For example, icon 302 may indicate that a panel application, for displaying panels with respect to executing applications, is executing, and icon 304 may indicate that a second application, for example, a contacts application, is executing.
FIG. 4 is an exemplary display 400 for processing device 100, which is similar to display 300, but has a different current focus that display 300. One may change the current focus of a display by using one or more navigation keys 204, such as, for example, , and/or . For example, to change the current focus of display 300 to that of display 400, the “” may be used. Of course, other implementations may use other keys to cause a change of focus.
When a user selects an execute key, which may be the center key of navigation keys 204, while the display includes a number of application indicators or icons, such as display 300 of FIG. 3, a display, such as display 500 of FIG. 5A, which pertains to the application indicator or icon that is the current focus of the display, such as APP1 of FIG. 1, is displayed. Icon 304 may be enlarged to indicate that the currently displayed application is the application represented by icon 304. Instead of, or in addition to enlarging icon 304, other techniques may be used for indicating that icon 304 pertains to the currently displayed application. For example, reverse video, specific color highlighting, blinking, as well as other techniques may be used.
In implementations consistent with the principles of the invention, some applications may include more than one view of the data. Such applications may indicate multiple views by using tabs, as shown in exemplary display 510 of FIG. 5B. Exemplary display 510 has three tabs, representing three views of APPLI data. A user may select a tab to cause a view associated with the selected tab to be displayed. In alternative implementations, buttons, indicators, or icons may be used instead of tabs. Further, a display may have more or fewer tabs than a number of tabs shown in FIG. 5B.
When viewing an application display screen, such as display 500 or 510, or when viewing a display, such as display 300 of FIG. 3, selection of panel button 206 may cause an option panel to be displayed over at least a portion of the current display. FIG. 6 illustrates an exemplary option panel 602. The option panel may be associated with the currently displayed application if viewing an application display, such as display 500 or 510, when panel key 206 is selected. Further, the option panel may be associated with a current focus, if panel key 206 is selected when viewing a display, such as exemplary display 300 or 400. The panel key 206 may provide an opportunity to perform left/right navigation to views of related information and panels of information, which provide non-disruptive access to other information. Related information may be grouped into tabbed views. Each view may be scrollable so that is can present a complete list of information. Up and down buttons can be utilized to scroll through a current view. Using left or right buttons can switch to related views. These may also be switched in that the panels may be up/down navigated. Each view may be a different representation of the same information or a set of related information. For example, one view could be a list of work contacts and a related view is a list of your friends. Each view is scrollable so that is presents a complete list of information.
The use of panels, in implementations consistent with the principles of the invention, may provide a switching capability to allow quick and convenient access to multiple applications. As an example, if one presses the panel key at any time, and the panels opens. From there, you can navigate left and right through the panels to see such information as upcoming appointment, the weather, incoming messages, people available to chat with, and so one. When you have what you need, the user presses the panel key again. The panels lower, and the user is right back where he or she was before using the panels key 206. The first panel that opens is preferably a special case where it displays actions that can be performed in the current activity.
Option panel 602 may include one or more indicators with respect to available options of the application associated with option panel 602. In some cases, option panel 602 may indicate no options if the associated application has no options.
FIGS. 7A through 7C are flowcharts that illustrate exemplary processing in implementations consistent with the principles of the invention. The process may begin by displaying a group of indicators or icons showing available applications, with a current focus on one of the applications, such as display 300 or 400 (act 702). Next, processing device 100 may determine whether a directional navigation key was selected, such as a right key, left key, up key, or down key (act 704). A key or button may be selected by touching an actual key or button or a displayed key (soft key) or button (soft button) with a user's finger, or by touching a displayed key with a stylus or an electronic pen, as well as by other means.
If a directional navigation key was selected, then processing device 100 may determine whether a panel is open and whether the selected key is a right key or a left key (act 706). If a panel is open and the selected key is a right or left key, then the current panel may be closed and a panel for another application may be opened. Otherwise, the current focus may be changed according to which directional navigation key was selected (act 708). Processing device 100 may then repeat act 704.
If, at act 704, processing device 100 determines that a directional navigation key was not selected, then processing device 100 may determine whether panel key 206 was selected (act 712). If panel key 206 was selected and no panel is open, the processing device 100 may open a panel for a current application (act 716). Otherwise, processing device 100 may close the currently open panel (act 718). Processing device 100 may then repeat act 704.
If, at act 712, processing panel determines that panel key 206 was not selected, then processing device 100 may determine whether the center or execute key was selected (act 720). If the center or execute key was selected, then the processing device 100 may execute according to a current focus of a display (act 722). Thus, if one application or task was active, that application may be placed in a background, an application associated with a current focus may become active and a corresponding display may be displayed by processing device 100. The background application or task may again be made active at a later point in time by the user. Processing device 100 may repeat act 704.
If, at act 720, processing device 100 determines that the center key was not selected, the processing device 100 may determine whether CLR key 208 was selected (act 724). If processing device 100 determines that CLR key was selected, then processing device 100 may determine whether CLR key 208 was selected or held for at least a predetermined time period (act 726). The predetermined time period may be at least two seconds or another suitable timer period. If CLR key 208 was selected or held for at least the predetermined time period, then an initial display may be displayed, such as, for example, display 300, which may be called a launcher display (act 728). Otherwise, processing device 100 may display a last shown application display screen (act 730). Processing device 100 may then repeat act 704.
In an alternative implementation consistent with the principles of the invention, when CLR key 208 is held or selected, a next last shown application display screen may be displayed every predetermined time period, such as, for example, every two seconds. For example, assuming that screens 1-3 are application display screens, if screen 1 is displayed, then screen 2 is displayed, followed by screen 3, when CLR key 208 is selected or held continuously, then after the predetermined time period, screen 2 may be displayed. After another predetermined time period, screen 1 may be displayed. In such an implementation, when the user stops selecting or holding CLR key 208, the currently displayed application screen may remain displayed.
FIG. 8 is a flowchart that illustrates exemplary processing in processing device 100 when a notification is received indicating that an event occurred to which a user may wish to attend, such as, for example, an incoming phone call. The process may begin with processing device 100 determining whether an event notification was received (act 802). If an event notification was received, then processing device 100 may cause a notice or icon to appear on a display screen or may cause a sound to be made, such as, for example, a ringtone, informing the user of an occurrence of an event (act 804). Next, processing device 100 may determine whether a particular key, for example, “*” was selected by the user. If the particular key was selected, then processing device 100 may display a panel over at least a portion of the currently displayed screen (act 808). The displayed screen may have icons or buttons pertaining to one or more options. For example, if the event is an incoming call, after the user selects the particular key, a screen or panel may be displayed requesting the user to indicate whether the incoming call is to be answered or whether the call should be forwarded to voicemail. FIG. 9 shows exemplary display 900, which processing device 100 may display if the event is an incoming call and the particular key was selected. Icon 904 may be displayed indicating the application (a telephone application).
In another implementation consistent with the principles of the invention, if an incoming call event arrives, then the processing device 100 may interrupt whatever the user is doing and may permit the user to answer the call or divert the call by selecting a key. In this implementation, the user need not select a key to display a panel including incoming call information.
The following provides more specific examples and operations that may be performed by processing device 100 in implementations consistent with the principles of the invention. FIG. 10 illustrates exemplary display 1000, which processing device 100 may display when a user changes a focus to “Accept the Call” of a display, such as, exemplary display 900 and selects an execute button, such as, for example, the center key. Display 1000 illustrates a panel covering at least a portion of a previous display. The panel informs a user of who is calling and may provide the user with one of several options, such as, for example, muting the call, placing the call on hold, and ending the call.
FIG. 11 illustrates an exemplary display 1100 including indicators or icons showing available applications on processing device 100. Display 1100 shows a contacts application, a photos application and a music application.
If a user selects panel key 206 while display 1100 is displayed, for example, an option panel 1202, such as shown in FIG. 12, may be displayed by processing device 100. Option panel 1202 may include one or more selections for the user, such as, for example, “about launcher” and “launch”. If the user selects “about launcher” by, for example, selecting the execute key while the current focus is “about launcher”, then a panel may be displayed that provides information about the launcher. If the user selects “launch” by, for example, selecting the execute key while the current focus is “launch”, then an application screen associated with an indicator or icon that is the focus of the display may be displayed.
FIG. 13 illustrates an exemplary display 1300, which is similar to display 1100 of FIG. 11, but has a focus on an indicator or icon associated with the music application. If the user selects panel key 206 while processing device 100 displays exemplary display 1300, a panel, such as panel 1402 may be overlaid onto display 1300, as shown by display 1400 of FIG. 14. Panel 1402 may indicate a name of a song that is being played by the music application, a total length of the song, a current progress indicator showing a current playing progress of the song, as well as indicators that may be selected by the user to pause, play a next song, play a previous song, or stop. Icon 1404 may be enlarged in display 1400 to indicate that the music application is playing.
If the user selects the execute button, while a display, such as exemplary display 1100 is displayed by processing device 100, a display, such as exemplary display 1500 of FIG. 15 may be displayed by processing device 100. Exemplary display 1500 shows names of contacts included in the contacts data. Exemplary display 1500 may include a number of tabs 1502, which the user may select to view related data. For example, a tab labeled “all” may be selected to cause all contacts data to be displayed. Another tab may be selected by the user to cause business contacts data to be displayed. A third tab may be selected to cause all family contacts data to be displayed.
When a user views a display, such as display 1500, and selects execute, a display, such as exemplary display 1600 of FIG. 16 may be displayed by processing device 100. Display 1600 may include contacts data pertaining to the focused item of contact data of display 1500. Display 1600 may include one or more tabs, which, when selected, may cause different or related views of the contacts data to be displayed. For example, selection of one tab may cause a profile to be displayed. The profile may include a photo and a contact profile message. The display associated with the profile tab may include several indicators which may be selected by the user. For example, a call indicator, a message indicator, an e-mail indicator, a meet indicator and a locate indicator may be included in the display.
Display 1600 may include a tab, which when selected, may cause detailed contact data with respect to the particular contact, to be displayed, as illustrated by exemplary display 1700 of FIG. 17A. Display 1700 may include contact name, address, and telephone number data. Other data may also be included, such as data pertaining to how the user knows the contact.
Display 1600 may also include a tab which, when selected, may cause a photo associated with the contact data to be displayed by processing device 100, as illustrated by an exemplary display 1710 of FIG. 17B.
FIG. 18 illustrates an exemplary display 1800, which is a contacts display showing a family view of the contact data. If the user selects panel key 206, while viewing a contacts display, option panel 1802 may be overlaid over at least a portion of the display. In exemplary option panel 1802, the user may be presented with several options including options to: view information about the contacts application, add a new contact, view a contact, edit a contact, and delete a contact.
If the user is viewing a display, such as exemplary display 1600 of FIG. 16, with a focus on “call”, and he or she selects the execute button, then a display, such as exemplary display 1900 of FIG. 19, may be displayed by processing device 100. The display may include exemplary display 1600 overlaid, at least partially, by panel 1902, which may include a name of a contact as well as a phone number.
