The Design and Implementation of Pointing Device for a Multimedia Users with Severe Physical Disability.

We developed a pointing device for manipulating multimedia on the personal computer for people who have a severe physical disability. We studied the design requirements of an input device for the disabled and developed a device that can be operated by rotating the head and by puffing and sipping from the mouth. Using infrared light as a communication link, the pointing device is composed of both a pointer and a controller. This new device allows the mouse cursor to move according to the angle of the head.
