ABSTRACT:
This invention relates to a device to allow a handicapped person with limited or no use of the hands to use a personal computer. The device includes a base which includes an inclined support onto which a computer keyboard is positioned. A support arm extends generally upwardly therefrom and is articulated for inward and vertical pivotable movement. A pointer is mounted on the support arm which is adapted to be articulated horizontally so as to position the nose end thereof adjacent a computer key to be depressed. The pointer is manipulated by the face of the operator who turns his head in the direction in which he desires the pointer to horizontally move, and the pointer is actuated outwardly by imparting a breath into a breath port of the pointer. The breath is detected by a pressure sensor transducer which actuates a solenoid in order to extend the nose thereof to depress a desired computer keyboard key.
