Patent Images
1. Video display device comprising:
- processor;
video display controlled by the processor, the video display defining a display plane and a z-axis perpendicular to the display plane;
user input device communicating with the processor to send user selection signals to the processor;
the processor executing logic comprising;
responsive to a viewer selection of a user interface (UI), presenting a UI object in a graphics plane of the video display device, the UI object being rendered in 3D by presenting two identical overlapping images of the UI object separated from each other by disparity distance;
responsive to a first command from the user input device, causing the UI object to appear to move in a first direction along the z-axis by increasing the disparity;
responsive to a second command from the user input device, causing the UI object to appear to move in a second direction along the z-axis by decreasing the disparity, the first direction being opposite to the second direction.

Abstract
A television for presenting video content in 3D has a video display controlled by a processor to present video content in a video plane and a user interface (UI) in a graphics plane. The processor receives input indicating a viewer desire to virtually move the UI up or back along a z-axis that is perpendicular to the video plane and responsive to the input change the location of the UI on the z-axis. This may done by altering image disparity produced to create a 3D effect.

7. Video display device comprising:
-
processor; video display controlled by the processor, the video display defining a display plane and a z-axis that extends out of the display plane; user input device communicating with the processor to send user selection signals to the processor; the processor executing logic comprising; responsive to a viewer selection of a user interface (UI), presenting a UI object in a graphics plane of the video display device, the UI object being rendered in 3D by presenting two overlapping images of the UI object separated from each other by disparity distance; responsive to a first command from the user input device, causing the UI object to appear to move in a first direction along the z-axis by increasing the disparity; responsive to a second command from the user input device, causing the UI object to appear to move in a second direction along the z-axis by decreasing the disparity, the first direction being different than the second direction. - View Dependent Claims (8, 9, 10, 11, 12)
