Reported are studies of man-machine communications systems and instructional procedures for facilitating the education of the handicapped. (The studies are a continuation of the program covered in C/R/I's preceding Interim Report.) To enhance the capability of the severely handicapped to communicate and thereby to develop intellectually, aspects of the study of this CYBERCOM family of man-machine systems include developing tests to observe and measure their effectiveness, studying man-machine interfaces, developing and testing instructional materials for teaching the use of the systems to the handicapped, demonstrating the systems to educators, and disseminating information for use in school systems. Specific topics covered include research and training programs with handicapped children, using bilateral-input interfaces for producing written communications; varied interfaces and transfer codes; telephone communications for the deaf or speech impaired; HAIBRL, a two-dot tactile system for reading and writing; sensory aids for the blind; and other collateral studies. Conclusions, recommendations, and future plans are detailed. Appendixes include descriptions of trainig, instructional materials and techniques, handwriting and typing samples, case studies, and other related items. (KW)
