Wearable messaging device for visually impaired person

Today´s technology has innumerable wearable solutions to alleviate the problems of disabled persons. The solution presented here is for the visually impaired persons and proposes to develop a wearable device that uses embedded system technology for data input functionalities in a hand glove based keyboard. The hand mounted keypad is easily adaptable by the user and provides flexibility as no prior knowledge is required to handle the hand mounted wearable device. The key glove acts as a prototype which enables the user to have the total functionality of a keyboard in one hand. Key glove is attached with alpha numeric keypad buttons that are mounted on the gloves. The character or number is generated by using mode Selection. (Alpha/Num). The hand mounted keypad can be interfaced with any kind of display device. It can be used for the visually impaired person to send message/call from one person to another using GSM modem. The GSM modem is attached with the gloves. Reply Message from others can be converted into text to voice format using Robo voice shield. The efficiency of the proposed work is evaluated with reference to decreased error rate and increased speed of operation. Voice conversion is also added to this device.
