Abstract
We developed a practical input system (headspace pointer), that patients in upper-level cervical cord injury c difficult for cerebral palsy patients with athetosis to operate the switch.an operate at will using remaining functions. This system consists of combination skill infrared transmission and angle detector system and they can operate it with breath switch. Under developing we also added mouse cursor position correction function because of slippage of the headset. The results of evaluating experiment showed that it was a useful PC system for patients in upper-level cervical cord injury. But it was
