ADAPTIVE ADJUSTMENT OF DEPTH CUES IN A STEREO TELEPRESENCE SYSTEM
First Claim
1. A system comprising, a stereoscopic display on which a subject views an object, the display coupled to a mechanism that adjusts stereo screen disparity to reduce the disparity between a fixation distance of the subject and a focus distance of the subject.

Abstract
Described is a stereoscopic display (telepresence) system that includes a depth cue adjustment mechanism for changing screen disparity to move a fixation distance of a viewer (subject) closer to a focus distance, thereby providing more desirable viewing conditions. In one aspect, the depth cue adjustment mechanism adjusts a depth cue by moving the fixation distance forward, and/or by moving the focus distance backward. Also described is detecting encroachment, where the object is perceived as being too close to the subject viewer for comfort, and adjusting one or more depth cues (e.g., object scale) to counteract the sensation of the encroachment.

- 11. A method performed on at least one processor, comprising, adjusting screen disparity to move a fixation distance of a stereoscopic image comprising left and right images closer to a focus distance, sensing for likely encroachment, and if detected, altering one or more depth cues to counteract the encroachment.
- 18. A system comprising, a telepresence system that receives left and right stereo images of an object over a plurality of frames, the telepresence system adjusting screen disparity to reduce a difference between a fixation distance of stereoscopic video corresponding to a sequence of the left and right stereo images closer to a focus distance, and dynamically adjusting one or more depth cues to counteract encroachment.
