Patent ID: 8002408

Claim:
A method of testing and/or training the depth perception abilities of an individual within a substantially unchanged visual vergence range, the method comprising: providing anaglyphic glasses having transmission filter lenses to the individual; instructing the individual to select a visual target displayed nearest to the individual; displaying, on a display device, a reference visual target and an anaglyphic three-dimensional second visual target, the visual targets colored to be perceived through the transmission filter lenses and being displayed with similar but non-identical depth information, such that the individual may perceive the reference visual target and the second visual target with substantially unchanged visual vergence, and with the second visual target being perceived by the individual as nearer to the individual than the reference visual target; receiving a response from the individual selecting the second visual target as being nearer to the individual than the reference visual target; determining at a control unit whether the visual target selected by the individual corresponds to the visual target displayed with depth information so as to be perceived as nearer to the individual; recording the time elapsed for the individual to respond and recording the accuracy of the response of the individual.
