Abstract

This work presents a simple method to study of tactile perception of visual handicapped persons using a low cost vibro-tactile device. It is based upon postulates, created by authors that believe on the development of a low cost vibrotactile mechanism that can turn into a productive resource to citizens that carry visual disabilities, aggregating value to the department this study is planned to and becoming even more important to the academic community. To justify this importance, the previously traced goals on the methodology of this work were followed, seeking, through the experimental model proposed by the other researcher, to identify which advantages a person with visual disabilities can gain when using low cost apparatus that help on social including. In this study, the comprehension of the main experiments about this theme, are analyzed in details. The results shows that the application of a low cost multi-channel vibro-tactile device for visual handicapped persons, enables a satisfactory mechanism of sociability enhancement help.
