Wearable Solution for Visually Impaired Person

Abstract

The proposed work explores a wearable messaging device that uses embedded technology for visually impaired person. The data input functionalities used in a hand glove based keyboard of existing technologies. The hand –mounted keypad is user friendly to the visually impaired and is easily adaptable. No prior knowledge is required to handle this hand mounted wearable device. The key glove is a prototype that enables users to have total functionality of a keyboard in one hand. Key glove is attached with alpha numeric keypad buttons are mounted in fingers. To generate key press codes by touching combination of buttons. These buttons are mounted in fingers and the combination of two finger can be used to generate character. Compared to existing work that uses multi sensor contacts, the proposed work increases the character set using finger contact combination. The hand mounted keypad can be interfaced with any kind of display device. It can be used for visually impaired person to send message in text format and receive reply from others in voice format using Arduino GSM kit. The efficiency of the proposed work is evaluated with reference to decreased error rate and increased speed of operation.
