title: Microcomputer-based communication augmentation systems for two nonspeaking, physically handicapped persons with severe visual impairment.
abstract: Two different microcomputer-based communication systems were developed for nonspeaking physically handicapped individuals with severe visual impairment. One subject was 24 years old and had an inoperative optic glioma which impaired motor function as well as vision. The second subject was cortically blind with severe motor limitation secondary to an automobile accident which occurred at 17 years of age. Both communication systems employed speech synthesis as a control feature to compensate for visual impairment. Both subjects have learned to use their communication systems. The second subject has not achieved extended, independent system use due to reduced vigilance and attention span.
