Uso de giroscópio para auxiliar pessoas com deficiência múltiplas no uso do Dosvox

Abstract

This article describes a solution that allows people with visual impairments who also have the inability to use hands, to have access to the Dosvox system, a system that enables the interaction between the visually impaired. In this solution, the Dosvox, whose operation is originally performed solely by keyboard, now can be operated via a gyroscope coupled to the user's head, whose movement is translated into a series of keystrokes, chosen to provide the full operation of the menus Dosvox which correspond to a high percentage of interaction with this system. The solution identified several problems to be solved, they were treated by means of algoritms and techniques presented in the article.
