A light probe adapted for use in training the blind.

The application of modern electronics technology has produced a number of new sensory aids for the blind. Serious limitations are presented, however, by the high cost and sophisticated training and maintenance requirements some of the new aids demand. This paper describes the design and development of an economical light sensor. Construction notes, including complete parts requirements, are given. Prototype applications to blind rehabilitation training and suggested uses as a personal sensory aid are discussed and critically evaluated.
