The paper describes new software and special input devices to allow physically impaired children to utilize the graphic capabilities of personal computers. Special input devices for computer graphics access--the voice recognition card, the single switch, or the mouse emulator--can be used either singly or in combination by the disabled to control graphics software. The disabled who have no problem in speech production sounds can use the speech recognition system; the disabled who have phonation problems may use a single switch activated by simple push actions coupled with suitable software. Newly developed by the authors is the mouse emulator which allows control of both graphic and communication software by means of simpler movements than those required to use a standard mouse. Two push-buttons allow either selection of objects displayed on a screen or activation of a function related to the chosen object. The pointer controller allows the user to move objects around the screen. Both standard and specially developed graphic software can be used. The mouse emulator can also serve as a pointer communication aid for nonspeaking disabled individuals. A special multichannel input interface was developed by the authors to allow motor disabled persons to produce three-dimensional pictures on the screen. This interface is described in some detail.
