Abstract

A method performed by a processing system with content display management includes identifying a first added content in a set of added contents that overlap and forming a display image to include the first added content such that a first portion of the first added content is partially transparent with respect to remote content captured by a remote system and a second portion of the first added content is opaque with respect to at least a portion of second added content in the set of added contents.

Claims

1. A method performed by a processing system with content display management, the method comprising:

identifying a first added content in a set of added contents that overlap; and

forming a display image to include the first added content such that a first pixel of the first added content is partially transparent with respect to remote content captured by a remote system and, at the same time, the first pixel of the first added content is opaque with respect to all other added contents.

2. The method of claim 1 further comprising:

displaying the display image.

3. The method of claim 1 further comprising:

determining a stacking order of the set of added contents; and

identify the first added content as the top-most content in the stacking order.

4. The method of claim 1 wherein a first portion of a second added content overlaps with the remote content but not with the first added content.

5. The method of claim 4 further comprising:

forming the display image such that a second pixel in the first portion of the second added content is partially transparent with respect to the remote content.

6. The method of claim 1 wherein the remote content is captured by the remote system to include a remote user and received by the processing system.

7. The method of claim 1 further comprising:

capturing local content to include a local user; and

providing the local content to the remote system.

8. The method of claim 1, wherein a presence of an obscured portion of second added content is indicated in the display image by a color.

9. The method of claim 1, wherein a presence of an obscured portion of second added content is indicated in the display image by a small change in transparency of the first added content.

10. The method of claim 1, wherein the amount of transparency applied to the remote content depends upon the type of the first added content.

11. The method of claim 1, wherein a perspective of the remote content is from behind a transparent display.

12. The method of claim 11, wherein the remote content is modified to coordinate with displayed added content.

13. A system comprising:

a display; and

a control unit to cause the display to display first content captured by a remote system to include a remote user and second content;

wherein the control unit is to cause the display to display third content that overlaps with a first portion of the first content and a first portion of the second content such that a first pixel in the overlapping portion of the third content is partially transparent with respect to the first portion of the first content and, at the same time, opaque with respect to the second content.

14. The system of claim 13 wherein the first content is captured by the remote system to include a remote user.

15. The system of claim 13 wherein a portion of the second content overlaps with a portion of the first content but not the third content, wherein a second pixel in the overlap region of the second and first contents but not the third content is transparent to the second and first content.

16. The system of claim 13 further comprising:

a camera;

wherein the control unit is to cause the camera to fourth content to include a local user and provide the fourth content to the remote system.

17. An article comprising at least one machine-readable storage medium storing instructions that, when executed by a processing system, cause the processing system to:

set a first pixel of first content to be partially transparent with respect to second content captured by a camera that overlaps with the first content;

at the same time, set the first pixel to be opaque with respect to a third content that overlaps with the first content; and

provide the first content to a display for display.

18. The article of claim 17, wherein the second content is captured by a remote system to include a remote user.

19. The article of claim 17, wherein the third content overlaps with the second content.

20. The article of claim 17, wherein the instructions, when executed by the processing system, cause the processing system to:

set a second pixel in a second portion of the first content to be opaque by combining the first content with the second content but not the third content.
