Desktop-based opto-cognitive device and system for cognitive assessment

摘要

A highly portable desktop arrangement for cognitive testing which eliminates environmental effects is provided by a clam shell enclosure having a face mask on one face and housing a computer screen at an opposing wall, with accurate gaze direction measurement made by determining the position of the pupil if an individual whose face is pressed to the mask for eliminating head movement relative to the computer screen.

主权项

1. A desktop based opto-cognitive system for cognitive assessment comprising:
an enclosure having a back plane and a front face plate with a mask therethrough adapted to receive an individual's face in a light tight fit and adapted to position the individual's face such that a normal to the individual's face is normal to the back plane of said enclosure; a computer screen positioned within said enclosure such that said computer screen is parallel to said back plane; an illumination device aimed at said mask and adapted to impinge on an eye of said individual when the face of said individual is pressed against said mask so as to illuminate said eye for contrasting the pupil of said eye as opposed to the white area of the eye of said individual; a camera within said enclosure, focused on said eye and having an output used to determine gaze direction; and, a processor coupled to said computer screen for presenting a moving object thereon, and coupled to the output of said camera for detecting gaze direction of said eye and for calculating cognitive ability based on the ability of said individual to track said moving object with said eye.
