Abstract :
A custom microprocessor-based output interface board for use in a reading aid for the visually impaired is described. The board drives the Optacon, the Stereotoner, and an enlarged Optacon-style LED display in real time under host microprocessor control. It is a versatile tool for simulating and evaluating operational features in blind reading aids.
