A Method of Assessing a Visually Impaired Person's Ability to Use a Closed Circuit Television Reading Machine

The following study represents an attempt to devise a more effective means of assessing potential users on closed-circuit television reading machines. It concluded that by establishing corrective values for factors such as age, magnification and working distance used, reliable predictions of reading speed are possible.

Television Presentation

Discussion, study, and research concerning the use of television as a medium of instruction have been taking place for slightly more than a decade. For the past five years this type of educational research has proceeded at a fast, accelerating rate. Past research has indicated, with demonstrated validity in a number of cases, that televised instruction can be an effective means of educating students.

The Subject ◽

Potential Use

The potential use of closed-circuit television with a young severely visually impaired girl was assessed to explore the development of visual skills related especially to the development of concepts. The subject underwent 63 training sessions over a six-month period. At the end of training, she could recognize lines, forms, shapes, letters, numbers, and words and could read short sentences. Informal brief replication efforts with four other subjects showed similar results.
