Working of AccelerometerWorking of Accelerometer:- :-

This technology uses a device called This technology uses a device called accelerometer which is used for measuring accelerometer which is used for measuring motion. This is used to detect the stops, stars, arcs motion. This is used to detect the stops, stars, arcs and loops and then transmit this information to a and loops and then transmit this information to a small microprocessor that would make sense of it small microprocessor that would make sense of it as text. It records movement by using the earth as text. It records movement by using the earth gravity system, whether you write on paper or in gravity system, whether you write on paper or in air .air .

TYPES OF ACCELEROMETERTYPES OF ACCELEROMETER

2axes:- This accelerometer measure acceleration in two axes. Example of two axes accelerometer is ADXL202 accelerometer.

3axes:-This accelerometer measures acceleration in three axes. An example for three axes accelerometer is Tronics +/-2g accelerometer.

In this phase, the recorded acceleration In this phase, the recorded acceleration signals are then transcipted to its original signals are then transcipted to its original form . Here this aspect is solved using form . Here this aspect is solved using ‘simple’ double integration method in ‘simple’ double integration method in order to retrace the pen tip movement order to retrace the pen tip movement on paper. on paper.
