In various embodiments, the present invention relates to application management in electronic devices, and more particularly to systems and methods for selectively causing activities, such as applications, to hibernate in a computing environment wherein multiple applications can be open concurrently.
Many currently available computing devices run operating systems that offer users the opportunity to run several software applications at the same time, and even to perform several activities simultaneously, within a single software application and/or among two or more software applications. For example, a user may open an e-mail application, a word processing application, an on-screen calculator, and a web browser, so that all of the applications are open concurrently. The user may open several documents within the word processing application, and may open several e-mail messages. Such an arrangement allows the user to move from one task to another by keeping these various applications and activities open at the same time.
Various visual paradigms are available for presenting multiple concurrently running applications and other activities within a graphical user interface. In some computing systems, multiple overlapping windows are made available, with each window representing an application, document, task, or other activity. A desktop metaphor is often employed, wherein the user can move and resize windows on a display screen by direct manipulation. At any given time, one window has focus (usually indicated as such by being situated on top of the other windows). Other windows may be visible, invisible, or partially visible (for example if they are partially or completely obscured by other windows). A user can switch from one activity to another by causing a different window to have focus; this is commonly accomplished by clicking on a visible portion of the window being activated, or by clicking on a button or icon representing the window in a task bar, quick-launch area, or similar construct. In some operating systems, pop-up menus and/or keyboard shortcuts may be available for switching among applications, documents, or other activities.
In other systems, a card metaphor is used, in which each application or other activity can be represented within an area of the screen. Cards can be moved on a display screen, for example by direct manipulation via a touchscreen user interface. Several card viewing modes can be provided. Various embodiments of a card metaphor are described in related U.S. patent application Ser. No. 12/126,145, filed May 23, 2008, for “Navigating Among Activities in a Computing Device”, and related U.S. patent application Ser. No. 12/416,279, filed Apr. 1, 2009, for “Card Metaphor for Activities in a Computing Device”, the disclosures of which are incorporated herein by reference.
Such systems provide mechanisms by which several applications and/or other activities can be kept open concurrently, allowing a user to easily switch between activities with minimal overhead. The ability to keep several activities open is advantageous because it avoids the need to repeatedly open and close applications. In addition, many systems (including those described above) allow users to view output from (and/or interact with) two or more activities on a common screen (or on multiple screens) at the same time. Cards or windows from two or more applications can be displayed simultaneously, allowing a user to refer to one while interacting with another, or to perform other tasks that involve interaction with two or more applications. Certain operations benefit greatly from such an arrangement, such as, for example, cutting and pasting content from one application to another.
Mobile devices such as smartphones, personal digital assistants, music players, handheld computers, and the like are becoming increasingly powerful. Many are now able to run several applications concurrently, and to perform sophisticated functions that rival traditional computing devices. However, many such devices have limited computing resources, including limited processor speed and/or available memory. Owing to these limitations, such devices can often run a limited number of applications concurrently; exceeding the limit can cause poor performance, instability, crashes, or other detrimental effects.
In such devices, if a user attempts to open an application, open a document, or initiate another activity that causes a memory or processing limit to be reached, the user may be presented with an error message informing him or her that the requested task cannot be performed unless some applications, documents, windows, cards, or other activities are closed first. Alternatively, the user may be presented with a message simply informing him or her that there is no memory left. At worst, the system may crash and the user may lose valuable data that he or she was working on.
None of these scenarios are satisfactory. What is needed is a system and method that handles resource limitations without impinging on the user's ability to perform the task he or she wishes to perform. What is further needed is a system and method that allows a user to open an activity even when many other activities have been opened, and even in the face of resource limitations on the computing system.
Even when a resource limit is not reached, the continued operation of an activity can be wasteful in terms of system resources, thus having a deleterious effect on the performance of the computing device. Running an application, or keeping a document open, that is not needed can consume valuable computing resources, including memory, processing time, network bandwidth, battery power, or any combination thereof. In some situations, users leave applications and/or documents open even when they are not needed. The user may not realize that an activity still running, or may not understand that the activity is consuming a significant amount of system resources. What is needed, therefore, is a system and method for detecting such conditions and avoiding wasteful use of system resources for activities that are left open but are not in active use.
In various embodiments, the system and method of the present invention operate in an electronic device capable of running two or more software applications concurrently. In various embodiments, each software application may be capable of opening two or more documents, or enabling two or more activities concurrently. The term “activity” is used herein to refer to a software application, task, document, message, page, image, card, window, content item, or any other construct representing data and/or programmatically definable functionality, and with which the user can interact via a user interface on the electronic device. In various embodiments described herein, activities can be represented by a user interface on a display screen, and a user can interact with activities via an input device. In various embodiments, the electronic device may present multiple concurrent activities using any desired paradigm or metaphor, including for example a desktop metaphor having multiple overlapping windows, or a card metaphor as described in related patent applications mentioned above. For example, in a card metaphor, activities are represented by “cards”, which is a term used herein to refer to areas of the screen that can be moved and manipulated by the user. Users interact with cards to launch, terminate, and reorder activities, as well as to navigate among activities and perform other operations.
In various embodiments, some activities may be open but not visible on the display screen; for example they may be moved off-screen, minimized, overlapped, or the like; the user can move items on the display or perform other operations to cause these open activities to become visible. In various embodiments, multiple documents, windows, or cards can be open and active concurrently for a given software application; the term “activity” can refer to the software application itself and/or to individual documents, windows, or cards associated with the software application.
In various embodiments, the system and method of the present invention selectively cause certain activities to hibernate, or “freeze”, so as to free up system resources for other activities that are in active use. A determination is made as to which activities should hibernate, for example based on a determination as to which activities have not been used recently or based on relative resource usage. In one embodiment, when an activity is to hibernate, its state is preserved on a storage medium such as a disk, so that the activity can later be revived in the same state and the user can continue with the same task that was being performed before the activity entered hibernation. In a situation where multiple documents, windows, or cards are open and active concurrently for a given software application, the software application itself can hibernate, or individual documents, windows, or cards associated with the software application can hibernate individually.
For purposes of the description provided herein, the term “hibernate” refers to the operation by which an activity (such as an application, document, card, or window) is made dormant, and its current state information is stored in some storage medium, so as to reduce usage of certain system resources such as, for example, memory. In one embodiment, hibernating activities remain visible on-screen, in the same manner as active, or “live”, activities, although a distinctive visual characteristic can be applied to inform the user that the activity is hibernating; for example, the activity can be presented in a grayed-out or dimmed fashion, or with a superimposed or adjacent icon indicating that it is hibernating. In other embodiments, other mechanisms can be used to indicate that an activity is hibernating. In other embodiments, no visual indicator is provided to inform the user that the activity is hibernating.
In one embodiment, activities hibernate automatically in response to a determination that additional system resources are needed, or in response to a determination that an activity is having an adverse effect on system performance, or in response to other trigger events or factors. In one embodiment, a determination as to which activities should hibernate is made, based on how recently the activity has been used, the amount of system resources being used by the activity, and/or other factors. In another embodiment, a user can manually specify that one or more activities should hibernate.
In one embodiment, a hibernating activity is revived automatically when a user attempts to interact with the activity. In another embodiment, a hibernating activity is revived automatically when sufficient system resources become available to run the activity without adversely affecting other activities. In another embodiment, a hibernating activity is revived in response to an explicit user command. When an activity is revived, state information is retrieved from storage and, if needed, the activity is re-launched so that the user can resume interacting with it at the same point as when it initially was placed into hibernation.
In one embodiment, revival of a hibernating activity may cause another activity to automatically hibernate, particularly if system resources need to be made available to revive the first activity.
In one embodiment, a hibernating activity may be closed, or dismissed, after some period of time or in response to some event. Such dismissal may be appropriate, for example, when there is some indication that the user is no longer interested in the activity. Dismissal of an activity causes state information to be discarded, although any open data files may be saved.
In some embodiments, rather than automatically causing activities to hibernate and/or be dismissed, the system may prompt the user with a recommendation that one or more activities hibernate and/or be dismissed (either to conserve system resources or for any other reason). The user is then given an opportunity to indicate whether or not the recommended action takes place.
In some embodiments, the user can control whether and when automatic hibernation and/or automatic dismissal takes place, for example via a preferences or options screen.
In some embodiments, activities may hibernate for reasons other than resource management. For example, it may be desirable to maintain a limit on the total number of currently active, or “live”, activities, so as to reduce user confusion that may take place if too many activities are active simultaneously. In such an embodiment, activities may hibernate automatically when such a limit is reached. Alternatively, the user may be prompted to select activities for hibernation, while allowing the user to decide whether or not activities should hibernate.
In one embodiment, wherein the invention is implemented in a system using a card metaphor, a persistent positional relationship is established and maintained among cards. The positional relationship can be a one-dimensional sequence or some more complex two-dimensional relationship. The positional relationship is persistent in the sense that it does not change unless the user indicates that it should be changed, or some other event takes place that indicates a change is warranted (such as non-use of an activity, or an activity crashing or being dismissed). In one such an embodiment, cards for hibernating activities can maintain their positions with respect to cards for live activities, although a visual indicator can be provided to denote the hibernation state. In other embodiments, cards are repositioned within the sequence when their activities hibernate, for example by being grouped with one another, or moved to the end of the sequence of cards, or otherwise repositioned to indicate the hibernation state.
In one embodiment, the techniques of the present invention are applied to any activity that can be performed on a computing device or any software element that can appear on a computing device. The use of the term “activity” is intended to refer to any such activity or element, and is not intended to be limited strictly to a self-contained software application. Thus, the hibernation and revival techniques described herein can be applied to software applications as a whole, and/or to individual documents, tasks, dialog boxes, windows, applets, panels, panes, toolbars, menus, content items, images, videos, control panels, or the like.
In one embodiment, the techniques described herein can be combined with the card repositioning and/or grouping techniques described in related U.S. patent application Ser. No. 12/416,279, filed Apr. 1, 2009, for “Card Metaphor for Activities in a Computing Device”, the disclosure of which is incorporated herein by reference.
The various features described above and herein can be implemented singly or in any combination, as will be apparent to one skilled in the art. Additional features and advantages will become apparent in the description provided below.
The accompanying drawings illustrate several embodiments of the invention and, together with the description, serve to explain the principles of the invention. One skilled in the art will recognize that the particular embodiments illustrated in the drawings are merely exemplary, and are not intended to limit the scope of the present invention.

System Architecture
Referring now to
Device 100 also includes storage device 1102, which may be a hard drive, flash memory, or any other fixed or removable component for data storage. In one embodiment, as discussed in more detail below, the system and method of the present invention store activity state information 1103 in storage device 1102 when activities enter hibernation, and retrieve such state information 1103 from storage device 1102 when reviving activities.
In various embodiments, device 100 can also include additional components, such as, optionally, network interface 1107 (such as Bluetooth and/or wired connectivity to a network such as the Internet), and/or cellular network interface 1108 providing cellular telephony functionality. It is well known to provide such functionality on smartphones.
One skilled in the art will recognize that the functional architecture depicted in
In one embodiment, the invention can be implemented as a feature of an application management paradigm for a software application or operating system running on such a device. Accordingly, certain aspects of the present invention can be implemented as part of a graphical user interface for controlling software on such a device.
In various embodiments, the invention is particularly well-suited to devices 100 such as smartphones, handheld computers, and PDAs, which often have limited resources such as processing power, memory, and network bandwidth, and which are capable of running several software applications concurrently. One skilled in the art will recognize, however, that the invention can be practiced in many other contexts, including any environment in which it may be desirable to provide a mechanism for causing activities to hibernate, whether to conserve system resources, improve system responsiveness, reduce user confusion, or for any other reason. Accordingly, the following description is intended to illustrate the invention by way of example, rather than to limit the scope of the claimed invention.

In the example of
In one embodiment, screen 101 is touch-sensitive, so that a user can launch a software application, or open a document, or initiate any other activity by touching a displayed icon 106, and can manipulate cards 301 and other displayed objects by touching and/or gesturing in various areas of screen 101. For example, in one embodiment the user can dismiss an application or other activity by dragging its card 301 upward towards the top edge of screen 101. In one embodiment, the user can access open activities whose cards 301 are not currently visible on screen 101, by dragging on-screen cards 301 in a horizontal direction, thus causing off-screen cards 301 to come into view. Details of such operations are described in the related patent applications cited above. One skilled in the art will recognize that the present invention can be implemented in other embodiments wherein screen 101 is not touch-sensitive, and that the techniques described herein are not limited to applicability with any particular input mechanism.
In one embodiment, device 100 also includes a touch-sensitive gesture area 102 for entering gesture-based commands, as described in the above-referenced related patent applications. In another embodiment, screen 101 and/or gesture area 102 is sensitive to user motion in proximity to the surface, so as to detect gestures and commands performed near the surface but without necessarily contacting the surface.
For illustrative purposes, device 100 as shown in
In various embodiments, touch-sensitive screen 101 and gesture area 102 can be implemented using any technology that is capable of detecting a location of contact and/or user motion proximate to the surface. Alternatively, as mentioned above, the present invention can be implemented with other user input mechanisms, such as a keyboard, trackball, stylus, or the like.
In one embodiment, device 100 as shown in
Hibernation
In one embodiment of the present invention, device 100 selectively causes activities to hibernate. This can be done automatically, for example in response to certain trigger events or conditions, such as detection of a low-memory condition. Such a condition may occur, for example, when the number of open activities exceeds (or is close to exceeding) device's 100 capabilities, or when the performance, reliability, and/or stability of device 100 is/are in danger of being compromised because of an excess of concurrently running activities. The hibernation can take place automatically, without any user intervention. Alternatively, the user can be prompted to indicate whether to proceed with hibernation, so that hibernation takes place only if the user indicates that it should take place. In one embodiment, a user can manually initiate hibernation of an activity, for example by selecting a “hibernate” button or command.
By providing selective hibernation of activities, the present invention enables implementation of a system wherein a larger number of activities can be opened, and wherein the user is not burdened with repeatedly closing and/or opening activities, and manually restoring state, in order to avoid exceeding limits on system resources. As described in more detail below, hibernating activities can be easily revived as needed, with a minimum of delay and without requiring the user to explicitly relaunch or restore state.
It may also be useful to cause an activity to hibernate for other reasons, such as to simplify operation of device 100, conserve user attention, and/or to enhance security (for example so as to avoid keeping an activity open that might cause device 100 to be vulnerable to unauthorized access over a computer network).
In one embodiment, wherein a software application may have more than one card 301 associated with it, activities associated with individual cards 301 can be placed into hibernation independently of one another. Alternatively, activities for all cards 301 associated with a software application can be placed into hibernation.
In one embodiment, as described in more detail below, when initiating hibernation of an activity, device 100 saves the state of the activity in storage 1102 so that it can later be restored. A snapshot of the activity's user interface is taken. This snapshot, or a portion thereof, or an image derived therefrom, is used to replace the live view presented in the card 301 (or cards 301) corresponding to the activity. In one embodiment, a distinctive visual characteristic or effect is applied to the card 301 corresponding to the activity, so as to inform the user that the activity is hibernating and that the image shown on card 301 is a static snapshot rather than a live presentation of the user interface. In one embodiment, the distinctive visual characteristic is an icon or text indicator; in another embodiment, the image shown in card 301 is grayed-out, shown in black-and-white, or otherwise modified or transformed. In another embodiment, the size, orientation, or other visual characteristic of card 301 is changed to indicate that the activity is hibernating. In another embodiment the image shown in card 301 is darkened or lightened, for example by applying a transparent grayscale overlay, referred to as a “scrim”, atop on the image shown in card 301. In one embodiment, the scrim is applied by the operating system of device 100 when card 301 is being displayed; thus, display 101 shows the snapshot for card 301 with the scrim applied. In another embodiment, the scrim is applied at the time the snapshot is made, so that the snapshot image itself incorporates the scrim, and no additional processing need be applied when displaying the snapshot.
In one embodiment, the snapshot is taken at a relatively high level of resolution so that it can be scaled as appropriate depending on the current displayed size of the associated card 301. In one embodiment, the snapshot occupies the card 301 associated with the hibernating activity. In another embodiment, some animation is introduced, for example to emphasize the fact that the activity is hibernating. In yet another embodiment, hibernating activities are represented in some other manner, such as a generic image or textual indicator, rather than being represented by a snapshot of the user interface.

In the example of
In one embodiment, cards 301 for hibernating activities maintain their positions with respect to cards 301 for live activities. In other embodiments, cards 301 are repositioned within the sequence when their activities hibernate, for example by being grouped with one another, or moved to the end of the sequence of cards 301, or otherwise repositioned to indicate the hibernation state.
Cards 301 for hibernating activities can be moved, repositioned, and otherwise manipulated in the same manner as cards 301 for live activities, although cards 301 for hibernating activities are occupied by static snapshots of their respective user interfaces. Thus, in one embodiment, the various techniques for interacting with cards 301, as described in the above-referenced related patent applications, can all be applied to cards 301 for hibernating activities. As will be described in more detail below, certain actions performed by the user may cause a hibernating activity to be revived.
Referring now to
In one embodiment, cards 301 for hibernating activities can be displayed in other modes as well. Referring now to
As described in the above-referenced related patent applications, shuffle mode is optimized for reordering and manipulating cards 301 representing activities. In one embodiment, in shuffle mode, cards 301 are shown at a reduced size, thus permitting more cards 301 to be shown on screen 101 simultaneously. In one embodiment, when device 100 is in shuffle mode, cards 301 are arranged linearly as they are in card mode. The user can rearrange cards 301 as described above for card mode, and substantially all of the behaviors described above with respect to card mode also apply to shuffle mode. Thus, when the user drags a card 301 to the left or right within display screen 100, other cards 301 move in concert with the dragged card 301. Shuffle mode provides a way to rearrange cards while being able to view more cards 301 simultaneously.
As shown in
In the example of
Referring now to
As described in the above-referenced related patent applications, in grid mode, cards 301 are presented at a size that permits all cards 301 to be displayed simultaneously. Thus, for example, in
As described in the above-referenced related patent applications, in one embodiment, in grid mode, a minimum card 301 size (or a maximum number of displayed cards 301) is enforced, even if this means that only a subset of cards 301 can be displayed. Thus, in effect, once cards 301 have been scaled down to the minimum size (or once the maximum number of displayed cards 301 is shown on screen 101), no further downward scaling takes place. Rather, scrolling is permitted to allow the user to access remaining non-displayed cards 301. Some visual indication can be provided to inform the user that additional cards 301 can be accessed via scrolling, for example by showing the edges of cards 301 that are off-screen. The user can scroll, for example, by moving cards 301 to the left or right, or performing a gesture in gesture area 102, or by any other known means.
In the example of
In one embodiment, as described in the above-referenced related patent applications, cards 301 can be visually grouped with one another. Thus, cards 301 having some relationship to one another (such as cards 301 associated with a particular software application) can be displayed in a manner that indicates and/or reinforces the relationship. For example, cards 301 representing various web pages being viewed via a browser application can be grouped.
In one embodiment, if a software application associated with a group of cards 301 is hibernating, all cards 301 in the group are shown with static snapshots 152 and scrims.
For example, one visual paradigm for indicating groups of cards 301 is to depict the cards 301 in a manner that resembles a stack or deck, with a fully-visible front card 301 (or “top card”) and one or more additional cards 301 depicted as though they are behind the front card 301. Referring now to
Another example of a visual paradigm for indicating groups of cards 301 is to depict the grouped cards 301 at a different size or vertical offset with respect to other cards 301. Referring now to
Revival
In one embodiment, a hibernating activity is revived when a user attempts to interact with it. As described in the above-referenced related patent applications, if a user taps or clicks on card 301 for an activity, that activity is given focus; in one embodiment, device 100 switches to a full-screen mode wherein the user can interact with the activity. In one embodiment, if the user taps or clicks on card 301 for a hibernating activity, the activity is automatically revived so that the user can interact with it. In one embodiment, the user is first prompted, for example via a dialog box (not shown) asking whether the selected activity should be revived. In another embodiment, the activity is revived without first prompting the user.
Revival of one or more activities can take place in any display mode, whether card mode, full-screen mode, shuffle mode, grid mode, or any other mode. According to various embodiments of the invention, different types of trigger events might cause an activity to be revived. In one embodiment, switching from one mode to another can trigger revival; in other embodiments, incoming communications, alerts, attempts by the user to perform certain actions, and/or other events can trigger revival of one or more activities. In some embodiments, placing a card 301 in the center position causes its activity to revive. In other embodiments, revival takes place after card 301 has occupied the center position for some period of time.
In some cases, it may take time for an activity to be revived, as data from activity state information 1103 is being retrieved and the activity is re-launched. Referring now to
Once revival is complete, static snapshot 152 is replaced by a live user interface for the activity, and the scrim (or other visual indication of hibernation state) is dismissed. In one embodiment, a visual transition effect, such as a dissolve effect, is performed between display of the static snapshot 152 and display of the live user interface. Once the revival process is complete, progress indicator 151 is dismissed.

In one embodiment, a hibernating activity is revived when the user attempts to interact with the associated card 301 (other than to reposition or dismiss card 301). For example, if the user switches to full-screen mode while a card 301 for a hibernating activity is in the focus position (center position) on screen 101, in one embodiment the activity will automatically be revived.

Trigger Events
According to various embodiments of the present invention, hibernation of activities can be initiated in response to any of a number of different trigger events. In one embodiment, hibernation is initiated when a low-memory condition is detected. In other embodiments, hibernation is initiated when a determination is made that performance, reliability, and/or stability of device 100 may be compromised by depletion or overtaxing of system resources such as memory, processor speed, network bandwidth, or the like. Such conditions may occur, for example, when too many activities are open concurrently, or when some or all of the open activities consume an inordinately large fraction of available system resources.
In one embodiment, an attempt to launch a new activity can trigger hibernation of an already-open activity. For example, if the newly launched activity cannot be launched without first freeing up some system resources, or if the newly launched activity cannot be added to the set of currently open activities without detrimental effect to system performance, then hibernation of a previously open activity may be automatically initiated in response to the attempted launch of the new activity.
Referring now to
In this example, the system determines that launching the new activity will result in a low-memory condition or other overburdening of system resources. Accordingly, device 101 causes one of the open activities to hibernate, thus freeing up system resources and allowing the new activity to be launched. As shown in
Particular techniques for determining which activity should be selected for hibernation are discussed in more detail below.
In some embodiments, where a software application may be associated with two or more cards 301, cards 301 can hibernate and/or be revived independently of one another. Thus, a card 301 associated with a software application may be selected for hibernation while another card 301 for the same software application remains live. Conversely, a hibernating card 301 associated with a software application may be revived while another card 301 for the same software application remains in hibernation.
In other embodiments, a software application may be selected for hibernation, so that all cards 301 associated with that software application hibernate in concert with one another. Conversely, when the software application is being revived, all cards 301 associated with that software application are revived in concert with one another.
Method
Referring now to
In one embodiment, processor 1101 on device 100 detects 701 a low memory condition or potential low memory condition. In other embodiments, other events can trigger hibernation, such as detection that some fixed limit on open activities has been reached, or that some activities have been open without being used by the user for some period of time, or any other trigger event. If no such trigger event or condition has taken place, the method ends 799.
Processor 1101 selects 702 an activity (or more than one activity) for hibernation. The selection 702 can be made based on any factor or combination of factors, including memory usage, perceived importance of the activity, time since the activity was last viewed or used by the user, or the like.
In one embodiment, a priority order is established in order to determine which categories of activities should be placed into hibernation first. An example of such a priority order is as follows (from first to be placed into hibernation to last):
In one embodiment, the telephone application is not placed into hibernation if an active call is in progress.
In one embodiment, processor 1101 selects 702 an activity for hibernation according to the priority list. If hibernation of the selected activity is insufficient to resolve the low-memory condition (or whatever condition triggered the hibernation operation), another activity is selected. The process is repeated until the condition that triggered hibernation has been resolved.
In one embodiment, where a software application may have more than one card 301 associated with it, individual cards 301 can be placed into hibernation independently of one another. Thus, processor 1101 selects 702, for hibernation, an individual card 301 associated with a software application according to the priority list. In one embodiment, processor 1101 selects the card 301 occupying the most memory, or consuming the most system resources among those cards associated with the selected software application. In another embodiment, some other criterion (or more than one criteria) can be used for selecting an individual card 301 for hibernation. If hibernation of the activity associated with the selected card 301 is insufficient to resolve the low-memory condition (or whatever condition triggered the hibernation operation), another card 301 for that software application is selected. The process is repeated until the condition that triggered hibernation has been resolved.
Thus, in one embodiment, successive cards 301 for a given software application are selected for hibernation before cards 301 for a different software application are selected for hibernation. In another embodiment, cards 301 are selected based on the amount of memory or other resources they consume, regardless of which software application they are associated with. Thus, in this second embodiment, it is not necessary for all cards 301 for a given software application to be selected for hibernation before cards 301 for a different software application are selected.
In other embodiments, other criteria can be employed for selecting 702 activities for hibernation. Selection can be based on any of the following, alone or in any combination:
In one embodiment, a heuristic may be employed, including a combination of any or all of the above factors. One skilled in the art will recognize that the above list is merely exemplary, and that other factors may be employed.
Processor 1101 saves 705 activity state information 1103 in storage device 1102. If one or more individual cards 301 for a software application are being placed into hibernation, in one embodiment the state for those card(s) 301 is stored. In one embodiment, if no activities remain live for a software application, the software application is closed 706 so as to free up resources for other activities.
Processor 1101 determines 707 whether sufficient memory has been freed (or whatever condition triggered the hibernation operation has been resolved). If so, the process ends 799. Otherwise, processor returns to step 702 to select another activity for hibernation.

In one embodiment, while the activity is being revived, display screen 101 displays progress indicator 151. The activity being revived is launched 803, if it has not already been launched. In one embodiment, where an individual card 301 is being revived, the software application associated with the card 301 may already be live because other cards 301 exist and are live for the software application. Thus, it may not be necessary to launch the software application. Processor 1101 retrieves 804 activity state information 1103 from storage device 1102, so as to restore the state of the activity. The snapshot for card 301 is replaced 805 with the appropriate live user interface; any scrim or other indicator of hibernation state is dismissed. In one embodiment, a transition effect can be employed while the live user interface is introduced and the scrim or other indicator dismissed. Once the activity is fully revived, progress indicator 151 is dismissed 806, and the method ends 899.
User Notification
As described above, in one embodiment, activities are placed into hibernation automatically in response to certain trigger events. In other embodiments, the user may be prompted to indicate whether activities should be placed into hibernation.
In some embodiments, when resources (such as memory 1106) of device 100 are low, and activities are in hibernation, it may be desirable to prevent or limit the launch of new activities. Thus, if the user attempts to launch a new activity under such conditions, the user can be prompted to dismiss activities in order to free up resources for new activities. Such a prompt may also be appropriate when a new activity would otherwise be automatically launched, such as to display a new incoming email message or for any other reason.
Referring now to
In one embodiment, a visual indicator can be provided to indicate to the user that an activity is potentially subject to hibernation should the need arise, or that hibernation is imminent. For example, a visual indicator can be presented to inform the user that, should hibernation be deemed necessary or advisable, a particular activity (such as one that is low-priority or has not recently been used by the user) is likely to be selected. An example of such an indicator is a visual depiction of decay, for example superimposed on the user interface for the card 301.
In one embodiment, under certain conditions, hibernating activities can be dismissed entirely. For example, in one embodiment, if device 100 is turned off, or enters a sleep state, hibernating activities are dismissed, and their state information 1103 is discarded from storage device 1102. In one embodiment, any open documents associated with the hibernating activities are saved. In one embodiment, a notification can be presented to inform the user that these activities are to be (or have been) dismissed.
In one embodiment, hibernation is implemented as a prelude to dismissal. Thus, a two-stage process is employed, wherein activities are placed into hibernation to conserve system resources; then, after some period of time, if the hibernating activities are not revived, they are dismissed.
Desktop Metaphor
The card metaphor described above is merely one example of an environment for implementing the present invention. In other embodiments, the present invention can be implemented in connection with other types of user interfaces, including for example a desktop-based interface having overlapping windows.

Reference in the specification to “one embodiment” or to “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least one embodiment of the invention. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment.
Some portions of the above are presented in terms of algorithms and symbolic representations of operations on data bits within a computer memory. These algorithmic descriptions and representations are the means used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. An algorithm is here, and generally, conceived to be a self-consistent sequence of steps (instructions) leading to a desired result. The steps are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical, magnetic or optical signals capable of being stored, transferred, combined, compared, transformed, and otherwise manipulated. It is 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. Furthermore, it is also convenient at times, to refer to certain arrangements of steps requiring physical manipulations of physical quantities as modules or code devices, without loss of generality.
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 “displaying” or “determining” or the like, refer to the action and processes of a computer system, or similar electronic computing module and/or device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system memories or registers or other such information storage, transmission or display devices.
