METHOD AND SYSTEM FOR QUANTITATIVE ASSESSMENT OF VISUAL MOTION DISCRIMINATION

摘要

A method is presented to address quantitative assessment of visual motion discrimination in a subject, where the method comprises the steps of: (1) presenting a scene, comprising a plurality of elements and a background, to a subject on a display; (2) moving a plurality of elements relative to the scene; (3) receiving feedback from the subject; (4)quantitatively refining the feedback; (5) modulating the movement relative to accuracy of the received feedback; (6) monitoring the response error; (7) calculating a critical threshold parameter for the subject; and (8) recording a critical threshold parameter onto a tangible computer readable medium. An apparatus for quantitative assessment of visual motion discrimination of a subject comprising a display device, an input device, a control device, and a tangible computer readable medium. In its simplest sense, a quantitative assessment profile of visual motion discrimination by psychophysical responses is generated on a tangible computer readable medium.
