Computer interface to use head and eyeball movement for handicapped people

Abstract

In this paper we propose a computer interface device for handicapped people. Input signals of the interface device are movements of eyeballs and head of the handicapped. The movements of the eyeballs and head are detected by an image processing system. One feature of our system is that the operator is not obliged to wear any burdensome device like glasses and a helmet. The sensing performance of the image processing of the eyeballs and head is evaluated through experiments. Experimental results reveal the applicability of our system.
