Abstract

Our project is designed to help the unfortunate people who cannot
speak to communicate with us.
The project consists of a glove equipped with flex sensors that will
be worn by the person.
Flex Sensor plays the major role, Flex sensors are sensors that
change in resistance depending on the amount of bend on the
sensor.
The glove uses flex sensors, and accelerometers in three dimensions to
gather data on each finger’s position and the hand’s motion to
differentiate the letters.
The system works by sensing the voltage drop across the flex
sensors. And then the microcontroller converts the analog signal
from the sensors to letter and send it wireless to computer using zigbee.
Also we show the hand movements on the pc by visual basic .net.
