Google patents method to fix depth errors in 3D displays
Google describes a technique for stereoscopic displays that corrects visual glitches when objects overlap. The method adjusts the perceived depth of background elements while they are covered by foreground objects to prevent conflicting depth cues. Once the overlap ends, the background depth returns to its original setting.
In the filing’s own words
A depth conflict between objects displayed on a stereoscopic display occurs when a background object is rendered at a first depth that is smaller than a second depth of a foreground object overlaid on the background object. This conflict can be resolved by making the first depth of the background object larger while the foreground object is overlaid on the background object. After the overlapping condition concludes, the first depth of the background object may be returned to its original value.
What exactly they claim (claim 1)
1. A method, the method comprising: providing a first interpupillary distance to a first application to render first stereoscopic images at a first stereoscopic depth based on the first interpupillary distance; providing a second interpupillary distance to a second application to render second stereoscopic images at a second stereoscopic depth based on the second interpupillary distance; displaying the second stereoscopic images and the first stereoscopic images on a stereoscopic display, the second stereoscopic depth being less than the first stereoscopic depth; and providing a head-translation to the first application to render the first stereoscopic images to have a motion-parallax adjusted based on the head-translation while the first stereoscopic images are rendered at the first stereoscopic depth.
