Reading Machines for the Blind

Methods of reading for the blind are discussed, mindful of the human-factors and systems-engineering concepts involved. Machines to allow independent reading of ink-print by the blind are classified in terms of cost, complexity, auditory or tactile output, usefulness, ease of operation, and learning problems. Current experiments in character recognition are briefly mentioned, and in conclusion reference is made to using the technical advances on related problems to speed developments in this field. Also mentioned are the widespread application of the benefits of current research to both civilian and veteran populations and the probable need for prescription teams when devices become available for routine use.
