Communicator for Blind and Dumb People

Abstract

This paper provides technical method for poor eye sight persons or the blind and dumb person to communicate each other without any third person’s help. The main parameters are hand gesture sensing, RF communication, sound output. The aim of the idea is to provide a gesture sensing gloves to the visually impaired one, a hand hold which shows a sound as output. This is done with help of flex sensors and sd-card module with speakers, whereas the flex sensing gloves detects the hand gestures and transmit the signals through a radiofrequency transmitter. This transmitted signal is received in the other and shows the signal as a sound output using speaker by the already recorded sounds in the sd-card module. They can communicate each other easily without anyone’s help
