Abstract
A universal headset-mounted Neuropsychological Testing System utilizes eye tracking, with a single screen fixed with respect to the face and a dot on the screen driven to present an object that both eyes are focused on using a set of prisms, with the prisms eliminating interocular distance considerations. Ultrathin optics cast a virtual image at 40 centimeters and a universal mask against which the test taker'"'"'s face is placed fixes the single screen with respect to the face so that head movement is not a factor. Additionally, miniature cameras are located in the headset housing beneath the eyes, and a quick release tensioning unit provides easy headset mounting and removal. Moreover, all elements are located in the headset hood to eliminate the effects of head movement as well as environmental distractions.
