Presented is a report on the work of Cybernetics Research Institute (CRI) investigators on the development of deaf-blind communication and control systems (DEBLICOM). Described in Part One is one embodiment of DEBLICOM designed and built by CRI engineers. Reported in Part Two are experimental procedures and human factors considerations of component and sub-systems design. A description of a portable instructor's/user's controller is covered in Part Three. Part Four examines work on a speech synthesizer and a detailed manual developed at CRI. The status and the difficulties encountered in obtaining an artificial mechanical hand for use as a sub-system of DEBLICOM are reported in Part Five. It is noted that no failures have occurred in the tests of the prototype solid-state system. Also included are appendixes on instructional procedures for programing acceptable American speech with speech synthesizers, a brief report on phonemes, two articles on aids for children with multiple handicaps, and a work plan on DEBLICOM which describes 22 tasks in four work areas (DEBLICOM harness and code for the deaf-blind, mobility aids for the deaf-blind, synthesized speech for the deaf-blind, and project reports).
