Abstract

We report three experiments that explore the effect of enhanced binocular information on a range of perceptual judgements made under telepresence. Enhanced disparity is potentially useful as it would extend the range over which disparities are detectable, but it is not known whether, or for what tasks, we can use the enhanced information. Subjects positioned a 'mobile' within a scene viewed, via remote cameras, on a monitor. The tasks differed in the minimum geometry required to perform them, and we compared performance under monocular, normal binocular, and enhanced binocular conditions. Enhanced disparity improved performance on a 'nulling' task ; had no effect on a distance matching task; or on a shape task. We conclude that enhanced disparity is potentially useful for limited specialist tasks, but is unlikely to be useful in general. It remains possible that with training its usefulness could be extended.
