Title: Display systems and methods for clipping content to increase viewing comfort
IPC: G06F3/0346
Filed: 2022-03-11
Abstract: PROBLEM TO BE SOLVED: To provide display systems and methods for clipping content to increase viewing comfort. 
     SOLUTION: Augmented and virtual reality display systems increase viewer comfort by reducing viewer exposure to virtual content that causes undesirable accommodation-vergence mismatches (AVMs). The display systems limit display of content that exceeds an accommodation-vergence mismatch threshold, which may define a volume around the viewer. The volume may be subdivided into two or more zones, including an innermost loss-of-fusion zone (LoF) in which no content is displayed, and one or more outer AVM zones in which the display of content is stopped or clipped under certain conditions. For example, content may be clipped if the viewer is converging in an AVM zone and if the content is displayed within the AVM zone for more than a threshold duration.
