Abstract

Embodiments are directed to displaying data items in a carousel display panel and to efficiently presenting virtualized data in a carousel display panel. In one example, a computer system accesses a list of data items that include at least a first data item and a last data item which are to be displayed in a carousel display panel. The computer system displays the selected portion of data items in the carousel display panel and receives a user input indicating that the last data item in the list is to be displayed in the carousel display panel. The computer system then rotates the data items displayed in the carousel display panel to the last data item. The last data item is thus displayed, along with at least a portion of a second-to-last data item and the first data item in the list.

Claims

1. At a computer system including at least one processor and a memory, in a computer networking environment including a plurality of computing systems, a computer-implemented method for displaying data items in a carousel display panel, the method comprising:

an act of accessing a list of one or more data items comprising at least a first data item and a last data item, wherein at least a selected portion of the data items are to be displayed in a carousel display panel;

an act of displaying the selected portion of data items in the carousel display panel;

an act of receiving a user input indicating that the last data item in the list is to be displayed in the carousel display panel; and

an act of rotating the data items displayed in the carousel display panel to the last data item, such that the last data item is displayed, along with at least a portion of a second-to-last data item and the first data item in the list.

2. The method of claim 1, wherein each data item is dynamically realized into memory when the item is to be displayed.

3. The method of claim 1, wherein the carousel display panel is rotated backwards from the first data item directly to the last data item of the list of data items.

4. The method of claim 1, wherein the carousel display panel is integrated into a software application user interface.

5. The method of claim 4, wherein the software application user interface allows user touchscreen inputs to rotate the carousel display panel.

6. The method of claim 5, wherein the velocity of the user'"'"'s touchscreen input is used to determine where the in the list of data items the carousel display panel is to stop rotating.

7. The method of claim 5, wherein the velocity of the user'"'"'s touchscreen input is used to determine which data items are realized into memory and which data items are to be unloaded from memory.

8. The method of claim 1, wherein the number of data items realized into memory corresponds to a customizable window that encompasses a specified number of contiguous data items.

9. The method of claim 8, wherein the customizable window includes a specified number of non-displayed data items before the data items that are currently displayed and a specified number of non-displayed data items after the data items that are currently displayed on the carousel display panel.

10. The method of claim 9, wherein those items not included in the customizable window are discarded.

11. The method of claim 9, wherein the customizable window includes more non-displayed data items after the currently-displayed data items than before the currently-displayed data items.

12. The method of claim 9, wherein data items included in the customizable window are prefetched.

13. The method of claim 1, wherein the number of data items displayed and the number of data items that are partially displayed in the carousel display panel are customizable.

14. A computer program product for implementing a method for efficiently presenting virtualized data in a carousel display panel, the computer program product comprising one or more computer-readable storage media having stored thereon computer-executable instructions that, when executed by one or more processors of the computing system, cause the computing system to perform the method, the method comprising:

an act of accessing a list of one or more data items comprising at least a first data item and a last data item, wherein at least a selected portion of the data items are to be displayed in a carousel display panel;

an act of accessing a corresponding carousel display panel policy to determine an appropriate panel size for the carousel display panel, wherein the panel size indicates how many data items are to be displayed in the panel;

an act of loading into memory those data items that fit in the carousel display panel according to the policy-indicated panel size; and

an act of displaying at least a portion of those data items that were loaded into memory in the carousel display panel.

15. The computer program product of claim 14, further comprising:

an act of receiving a user input indicating that the last data item in the list of data items is to be displayed in the carousel display panel; and

an act of rotating the data items displayed in the carousel display panel to the last data item, such that the last data item is displayed, along with at least a portion of a second-to-last data item and the first data item in the list according to the policy-indicated panel size.

16. The computer program product of claim 15, wherein as the carousel display panel is rotated, data items are continually and dynamically loaded and unloaded from memory.

17. The computer program product of claim 15, wherein the rotating carousel display panel stops on given data item which is snapped into a spatially centered position.

18. The computer program product of claim 15, wherein the carousel display panel is arranged in at least one of the following manners:

horizontally and vertically.

19. A computer system comprising the following:

one or more processors;

system memory;

one or more computer-readable storage media having stored thereon computer-executable instructions that, when executed by the one or more processors, causes the computing system to perform a method for efficiently presenting virtualized data in a carousel display panel, the method comprising the following;

an act of accessing a list of one or more data items comprising at least a first data item and a last data item, wherein at least a selected portion of the data items are to be displayed in a carousel display panel;

an act of accessing a corresponding carousel display panel policy to determine an appropriate panel size for the carousel display panel, wherein the panel size indicates how many data items are to be displayed in the panel;

an act of loading into memory those data items that fit in the carousel display panel according to the policy-indicated panel size;

an act of displaying at least a portion of those data items that were loaded into memory in the carousel display panel;

an act of receiving a user input indicating that the last data item in the list is to be displayed in the carousel display panel; and

an act of rotating the data items displayed in the carousel display panel to the last data item, such that the last data item is displayed, along with at least a portion of a second-to-last data item and the first data item in the list according to the policy-indicated panel size.

20. The computer system of claim 19, wherein a separator item is displayed between the first data item and the last data items.
