Abstract: The disclosure provides a method for performing automated visual motor response assessment by receiving motor response input responsive to presenting visual stimulation, the method including: presenting a scene to a subject on a display; modulating contrast of a predetermined section of the scene; moving the predetermined section relative to the scene; providing a manual input device for tracking movement of the predetermined section; receiving tracked movement data from the manual input device; measuring a kinematic parameter of the tracked movement data; quantitatively refining the tracked movement; determining a relationship between at least one of the scene and quantitatively refined tracked movement; adjusting modulated contrast relative to the quantitatively refined tracked movement; and calculating a critical threshold parameter in relation to a subject.
