International ClassA61B 003/14AbstractA method and apparatus for determining the position of each eye of a human operator (12) with respect to a fixed reference point or with respect to each other by using electro-oculogram signals produced by eye movement. Human operator (12) wears sensor assembly (10) which includes a plurality of sensors (14) which are arranged to monitor right and left, as well as horizontal and vertical eye movement. The sensed electro-oculogram signals are processed by a microprocessor (60) into separate positional signals representing upward movement, downward movement, movement to the left, movement to the right, convergence, and divergence. These positional signals are used to control three dimensional imagery on a computer, video game, or other apparatus to be controlled, or for strabismus measurement and diagnosis. | |
