Abstract

An activity screen or multitasking screen for a mobile device includes a plurality of tiles, each of which corresponds to a different multitasking application on the mobile device. Each of the tiles is allocated to a distinct region on the activity screen, according to a specified layout. The layout may vary according to the number of tiles allocated in the activity screen, and in some examples a region of the activity screen is automatically subdivided to provide additional regions. The content displayed for each tile is selected, at least in part, based on the size of the allocated region, and consequently, of the tile. Content for each possible size of the tile can be pre-defined. Each of the tiles operates as an application entry point for its corresponding application, thus providing a means of access for applications concurrently executing on the device.

Claims

initially displaying an activity screen comprising a plurality of tiles, each tile corresponding to a different multitasking application on the device, each tile being allocated to a distinct one of a plurality of regions defined in a layout for the activity screen, content for each tile being selected and retrieved for display according to a size of the region to which the tile is allocated;

receiving notification of a further multitasking application executing concurrently with the different multitasking applications;

allocating a further tile corresponding to the further multitasking application to a next available one of the plurality of regions as defined in the layout;

retrieving content for display for the further tile, the content being selected for retrieval according to a size of the region to which the further tile is allocated; and

updating the display of the activity screen to include the further tile.

2. The method of claim 1, wherein at least one of the plurality of tiles includes dynamic application data obtained by the corresponding multitasking application.

3. The method of claim 2, further comprising:

receiving updated dynamic application data for the at least one of the plurality of tiles;

updating the at least one of the plurality of tiles with the updated dynamic application data; and

updating the display of the activity screen to include the updated dynamic application data.

4. The method of claim 1, wherein the activity screen is comprised in a homescreen display on the mobile device.

5. The method of claim 4, wherein the homescreen display further comprises at least one screen including a plurality of icons for launching corresponding applications.

6. The method of claim 1, further comprising, upon receiving the notification of the further multitasking application:

updating the layout for the activity screen to reflect a count of the multitasking applications;

reallocating each of the plurality of tiles and the further tile to a distinct one of a plurality of regions in the updated layout;

retrieving content for display for each tile thus reallocated, the content being selected for retrieval according to a size of the region to which the tile is now allocated; and

re-rendering the activity screen for display.

7. The method of claim 1, further comprising, upon receiving the notification of the further multitasking application:

if the count of multitasking applications exceeds the threshold,

altering the layout of the activity screen to subdivide the region corresponding to the last allocated tile to provide at least two further regions, the last allocated tile being associated with a first one of the at least two further regions;

allocating the further tile to another one of the at least two further regions, said region being the next available one of the plurality of regions; and

retrieving content for display for the further tile, the content being selected for retrieval according to a size of said region.

8. The method of claim 1, wherein the initially displayed activity screen comprises an initial plurality of regions of a first size, the method further comprising, upon receiving the notification of the further multitasking application:

if a count of multitasking applications does not exceed a count of the initial plurality of regions, carrying out the allocation of the further tile and the retrieval of content for the further tile;

if the count of multitasking applications exceeds the count of the initial plurality of regions,

identifying a region corresponding to a most recently-allocated tile having a size greater than a minimum size;

subdividing the identified region to provide two further regions;

associating updated position and size with the two further regions and any other regions subsequent to the identified region according to a predefined order; and

allocating the further tile to a last one of the plurality of regions according to the predefined order; and

retrieving content for display for each of the regions having an updated size, the content being selected for retrieval according to the updated size.

9. The method of claim 8, wherein the size of at least one of the plurality of regions is updated from a larger size to a smaller size.

10. The method of claim 1, wherein content for each tile comprises content selected from:

a snapshot of the multitasking application as last displayed on the mobile device, dynamic application data obtained by the corresponding multitasking application, and an icon, wherein content for at least one tile comprises at least one of dynamic application data obtained by the corresponding multitasking application and content for at least one other tile comprises an icon.

11. The method of claim 1, further comprising:

receiving a notification that a multitasking application has been terminated;

removing the corresponding tile from the activity screen; and

re-allocating the remaining tiles according to the layout of the activity screen.

12. The method of claim 1, further comprising:

receiving an instruction to move one of the plurality of tiles to a different region in the activity screen;

re-allocating that tile to the different region; and

re-allocating remaining tiles to the remaining regions in the layout.

13. A mobile device, including:

a display; and

one or more processors in communication with the display, the one or more processors being configured to enable;

initially displaying an activity screen on the display, the activity screen comprising a plurality of tiles, each tile corresponding to a different multitasking application on the device, each tile being allocated to a distinct one of a plurality of regions defined in a layout for the activity screen, content for each tile being selected and retrieved for display according to a size of the region to which the tile is allocated;

receiving notification of a further multitasking application executing concurrently with the different multitasking applications;

allocating a further tile corresponding to the further multitasking application to a next available one of the plurality of regions as defined in the layout;

retrieving content for display for the further tile, the content being selected for retrieval according to a size of the region to which the further tile is allocated; and

updating the display of the activity screen to include the further tile.

14. The mobile device of claim 13, wherein at least one of the plurality of tiles includes dynamic application data obtained by the corresponding multitasking application.
