ANAGLYPHIC DEPTH PERCEPTION TRAINING OR TESTING
First Claim
1. 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 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 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.

Abstract
An anaglyphic image presentation system is provided to evaluate and train a user'"'"'s depth perception abilities. In embodiments, anaglyphic image target components are presented to a user on a display device. The image target components are then viewed by the user through a set of transmission filter lenses. The transmission filter lenses present and block one or more target components based on the peak wavelength transmission associated with each lens. As a result, a user perceives an anaglyphic target image that is resultant from the perceived image target components when viewed through the transmission filter lenses.

4. 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 to the individual; instructing the individual to select a visual target displayed nearest to the individual; displaying, on a display device at a first time, an anaglyphic three-dimensional first visual target comprising a first set of overlapping anaglyphic image components and an anaglyphic three-dimensional second visual target comprising a second set of overlapping anaglyphic image components, the visual targets being displayed with similar but non-identical depth information, such that the individual may perceive the first visual target and the second visual target with substantially unchanged visual vergence, and with the first visual target being perceived by the individual as nearer to the individual than the second visual target; receiving a response from the individual at a second time selecting the first visual target as being nearer to the individual than the second 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.

5. A method of eliminating a ghost image associated with a presentation of an anaglyphic image, the method comprising:
-
providing anaglyphic glasses to an individual, where the anaglyphic glasses comprise a first transmission lens at a first wavelength and a second transmission lens at a second wavelength; presenting a background comprising the first wavelength at a first luminance brightness and the second wavelength at a second luminance brightness, where the first wavelength and the second wavelength are equally distributed across the background and, further, where a background luminance brightness is a sum of the first luminance brightness and the second luminance brightness; presenting a first anaglyphic image component, the first anaglyphic image component comprising the first wavelength at the first luminance brightness, wherein the first anaglyphic image component is perceived without a ghost image when viewed through the second transmission lens, and further wherein the first anaglyphic image component is indistinguishable from the background when viewed through the first transmission lens; and presenting a second anaglyphic image component, the second anaglyphic image component comprising the second wavelength at the second luminance brightness, wherein the second anaglyphic image component is perceived without a ghost image when viewed through the first transmission lens, and further wherein the second anaglyphic image component is indistinguishable from the background when viewed through the second transmission lens.
