1.2 Idea of project
Problem definition
 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.
 In case the need arises to communicate, the person will have to
just make the signs corresponding to our standard (will be
further discussed in chapter 4) symbolizing the various
characters to form words.
System definition
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 zig-bee.
We also used accelerometer to detect the motion and orientation of the
glove as result as we can use the same sign in different modes to produce
different letters.
