Morse Code Communication Aid for the Handicapped

Abstract

<p> A microprocessor driven display was built and programmed for the storage and reproduction of Bliss symbols. An explanation is offered for the success of the symbol language in teaching the handicapped. </p> <p> The hardware was designed to be inexpensive enough for classroom use, but still deliver adequate flexibility and resolution. Due to the complexity and variety of the symbols a method of data compaction was developed to reduce the required storage space. </p> <p> Initial tests are presented and suggestions are made for continuing the work. </p>
