The project aims in designing a system which helps the paralyzed people to express their basic needs along with password feature. This system makes use of gestures of body parts to announce their basic needs like food, water, etc..,. MEMS (Micro Electro-Mechanical Systems) accelerometer sensor is placed on the any movable part of the body of the paralyzed and he need to move that part in different directions to announce different needs.

The project aims in designing a system which helps the paralyzed people to express their basic needs along with password feature. This system makes use of gestures of body parts to announce their basic needs like food, water, etc..,. MEMS (Micro Electro-Mechanical Systems) accelerometer sensor is placed on the any movable part of the body of the paralyzed and he need to move that part in different directions to announce different needs.   Accelerometer is an electromechanical device that measures acceleration forces. These forces may be static, like the constant force of gravity pulling at our feet, or they could be dynamic - caused by moving or vibrating the accelerometer. MEMS accelerometers are one of the simplest but also most applicable micro-electromechanical systems. They became indispensable in automobile industry, computer and audio-video technology.   The control system consists of MEMS accelerometer sensor and microcontroller. Microcontroller collects data from the sensor and announces appropriate announcement for that data (gesture movement) through voice circuit, in which predefined needs are stored. This operation is done by the Microcontroller which is loaded with an intelligent program written using embedded ‘C’ language.  

The main objectives of the project are:  
  1. To provide a system for paralyzed to express his basic needs.
  2. Password feature to the system.
  3. Usage of MEMS sensor.
  The project provides exposure to the following technologies:
  1. Characteristics of MEMS accelerometer sensor.
  2. Voice circuit characteristics.
  3. Embedded ‘C’ programming concepts.
  4. Interfacing of MEMS and Voice circuit to Microcontroller.
  5. PCB designing concepts.
The major building blocks of this project are:  
  1. Regulated Power Supply
  2. MEMS accelerometer.
  3. Micro Controller
  4. Voice circuit.
  5. Crystal
  6. Reset
  7. LED indicators.
  Software’s used:  
  1. PIC-C compiler for Embedded C programming.
  2. PIC kit 2 programmer for dumping code into Microcontroller.
  3. Express SCH for Circuit design.
