Evaluation of Destination Guidance System for Visual Handicapped People

The Study explains the Evaluation of a Route and Destination Guidance System for the Visually Handicapped. In this study we constructed a walking guidance system for the visually handicapped with FM wave information given by low power transmitters assembled solar battery and a commercial portable radio. We tested 14 visually handicapped on two different roads. The efficacy of guiding information from the walking-guidance system was evaluated in walking experiments for the visually handicapped who can go out done by himself. As the results it became evident that the visually handicapped could understand the guiding information, suppose a psychological map and arrive at his destination precisely, and that the analysis of quantification method of third type (HAYASHI III) using the evaluation of guiding information enabled us to classify the subject into three groups and to show abilities to go out or to walk.
