Cyberlink : computer access for persons identified with multiple disabilities

Includes bibliographical references (pages 70-73)Data collected were from four subjects, identified with multiple disabilities, while\ud they used a hands-free computer interface system called Cyberlink Brainfingers. They\ud ranged in age from nine to twenty, attended one public special education school, and\ud were restricted in their ability to access curriculum, communication, or leisure activities\ud at the start of this study. The results of this study indicated that these subjects achieved\ud effective switch and mouse access controlling the Cyberlink system. The subjects\ud reached a level of expertise with the Cyberlink that allowed them to interact with a\ud computer and operate software independently from the researcher. At the beginning of\ud the study, the subjects were unable to create effective muscle control signals at their\ud forehead, but by the end of the study, the subjects were able to effectively control the\ud Cyberlink by using brainwave frequency signals at their forehead. During the course of\ud the study, functional and behavioral changes were observed from the four subjects.\ud Likewise, all four learned the Cyberlink Brainfingers sys~em at the same rate even though\ud the experimental protocol was designed to allow independent learning rates
