Abstract
A method and apparatus are presented to address quantitative assessment of visual form discrimination in a subject, where the method comprises the steps of: (1) presenting at least one scene to a subject on a display, said scene comprising a plurality of elements and a background; (2) distorting at least one geometric characteristic of at least one; (3) modulating the contrast level of the predetermined section of the scene; (4) moving the predetermined section relative to the scene, the movement being tracked by said subject via at least one input device; (5) receiving feedback from the subject via the input device; (6) quantitatively refining the received feedback relative to the scene; (7) adjusting at least one distorted geometric characteristic relative to the accuracy of the quantitatively refined feedback; (8) calculating the critical threshold parameter for the subject; and (9) recording the critical threshold parameter onto a tangible computer readable medium.
