This training module was developed in order to help teachers, parents, administrators, and other educational personnel to understand the problems and difficulties encountered by learners with disabilities trying to access microcomputers. The main body of the module describes hardware considerations and strategies for increasing microcomputer access, focusing on specific impairments (including autism, emotional handicaps, hearing impairments, mental handicaps, physical impairments, and learning disabilities), and utilizing a variety of adaptive devices. Activities are provided on such topics as modifying input/output accessibility and the utilization of speech output, touch-sensitive devices, speech input (as an alternative to the keyboard), and adaptive firmware cards and switch controls. Objectives, materials specifications, preparation guidelines, detailed procedures, and lists of recommended resources are included for each activity. Also included are a variety of supplementary handouts and overhead transparencies. (GL)
