Abstract

Embodiments are disclosed that relate to push and/or pull user interface elements in a user interface with which a user interacts via a depth camera. One embodiment provides a computing device configured to display an image of a user interface comprising one or more interactive user interface elements, receive from a depth camera one or more depth images of a scene including a human target, and display a rendering of a portion of the human target as a cursor positioned within the user interface and also provide to the display a rendering of a shadow of the cursor cast on one or more of the interactive user interface elements. The computing device is further configured to translate movement of the human target hand to the cursor such that movement of the human target hand causes corresponding actuation of a selected interactive user interface element via the cursor.

Claims

1. A computing system, comprising:

a logic subsystem; and

a data holding subsystem comprising instructions stored thereon that are executable by the logic subsystem to;

provide to a display an image of a user interface comprising one or more interactive user interface elements;

receive from a depth camera one or more depth images of a scene including a human target;

provide to the display a rendering of a portion of the human target as a cursor positioned within the user interface and also provide to the display a rendering of a shadow of the cursor cast on one or more of the interactive user interface elements; and

translate movement of the hand of the human target to the cursor such that movement of the hand of the human target causes corresponding actuation of a selected interactive user interface element via the cursor.

2. The computing device of claim 1, wherein the instructions are further executable to display a convergence the cursor and the shadow of the cursor on the selected interactive user interface element as the cursor moves toward the selected interactive user interface element.

3. The computing device of claim 1, wherein the instructions are further executable to display a plurality of shadows of the cursor.

4. The computing device of claim 3, wherein the instructions are further executable to display the plurality of shadows as arising from light sources at different distances relative to the cursor and/or different angles relative to the cursor and a display screen normal.

5. The computing device of claim 1, wherein the instructions are further executable to render the shadow as arising from one or more of a virtual point light source and a virtual directional light source.

6. The computing device of claim 1, wherein the instructions are further executable to render the shadow as arising from a virtual directional light source.

7. The computing device of claim 1, wherein the instructions are further executable to show the cursor in the form of a hand rendered from a depth image of the hand of the human target.

8. The computing device of claim 1, wherein the instructions are further executable to provide the image of the user interface, cursor hand, and shadows to one or more of a two-dimensional display and a three-dimensional display.

9. The computing device of claim 1, wherein the instructions are further executable to translate movement of the hand of the human target to the cursor such that movement of the hand of the human target causes the cursor hand to contact the selected interactive user interface element, and to display corresponding push and/or pull movement of the selected interactive user interface element.

10. In a computing system comprising a computing device, a display, and a depth camera, a method of operating a user interface, the method comprising:

displaying on the display an image of a user interface comprising one or more push and/or pull user interface elements;

receiving from the depth camera one or more depth images of a scene including a human target;

displaying a rendering of a hand of the human target as a cursor hand positioned within the user interface and also displaying a rendering of a shadow of the cursor hand cast on one or more of the push and/or pull user interface elements;

translating movement of the hand of the human target to the cursor hand such that movement of the hand of the human target is displayed as motion of the cursor hand toward a selected push and/or pull user interface element and converge of the cursor hand and the shadow of the cursor hand on the selected push and/or pull user interface element; and

after the cursor hand contacts the selected push and/or pull user interface element, displaying push and/or pull movement of the selected push and/or pull user interface element.

11. The method of claim 10, further comprising displaying a rendering of a plurality of shadows of the cursor hand.

12. The method of claim 11, further comprising displaying a rendering of plural hands as plural cursor hands.

13. The method of claim 10, further comprising rendering the shadow of the cursor hand as arising from a virtual point light source.

14. The method of claim 10, further comprising rendering the shadow of the cursor hand as arising from a virtual directional light source.

15. The method of claim 10, further comprising displaying the cursor hand as one or more of a mesh rendering, a stripe rendering, a voxel rendering, and a point sprite rendering of a point cloud of the hand of the human target.

16. The method of claim 10, further comprising displaying the user interface, the rendering of the cursor hand and the rendering of the shadow on a two-dimensional display.

17. The method of claim 10, further comprising displaying the user interface, the rendering of the cursor hand and the rendering of the shadow on a three-dimensional display.

18. A computer-readable storage medium comprising instructions stored thereon that are executable by a computing device to perform a method of operating a user interface, the method comprising:

providing to a display an image of a user interface comprising one or more push and/or pull user interface elements;

receiving from a depth camera one or more depth images of a scene including a human target;

providing to the display a rendering of a hand of the human target as a cursor hand positioned within the user interface and also providing to the display a rendering of a plurality of shadows of the cursor hand cast on one or more of the push and/or pull user interface elements;

translating movement of the hand of the human target to the cursor hand such that movement of the hand of the human target is displayed as motion of the cursor hand toward a selected push and/or pull user interface element and converge of the cursor hand and the plurality of shadows of the cursor hand on the selected push and/or pull user interface element; and

after the cursor hand contacts the selected push and/or pull user interface element, displaying push and/or pull movement of the selected push and/or pull user interface element via the cursor hand.

19. The computer-readable storage medium of claim 18, wherein the computer-readable storage medium is a removable computer-readable storage medium.

20. The computer-readable storage medium of claim 18, wherein displaying the rendering of the plurality of shadows comprises displaying a rendering of a plurality of shadows arising from virtual light sources having different distances from the cursor hand and/or different angles relative to the cursor hand and a display screen normal.
