Wireless Haptic Glove for Interpretation and Communication of Deafblind People

Abstract:

This article presents the construction of a low-cost assistance system to improve communication for deaf-blind people based on the universal Braille alphabet. The system is a glove that is composed of a Braille keyboard embedded in the front and vibrating micro-motors placed in the back, to write and perceive the messages respectively. The tactile switches allow the collection of digital signals to form the different Braille letters; once this information is collected it is processed and presented in a mobile application to later send a response to the haptic sensors that allow the Braille language to be coded so that the deaf-blind person can interpret it through the sense of touch. The experimental results show the correct functioning and usability of the glove for transmitting and receiving messages.
