The main aim of this project is to design and construct a head movement controlled device Switching system for physically challenged. The user can wear this device to head and with the Simple head movement’s he can request the basic needs like water, food or medicine by using ir Rays. User can also control the electrical devices like light, fan etc with the help of head movements. For example if the tilt is to the right side then the device will be “on” for the first time then Next time it will be “off”. In the same way, if the tilt is to the left side then another device is going To be controlled. The tilt is in upwards or downward direction the related need will be announced. This device is very helpful for paralysis and physically challenged persons. This project makes use of a relay for switching the devices and apr-9600 voice chip for Audio announcements and micro controller, which is programmed, with the help of embedded assembly Instructions. This microcontroller is capable of communicating with transmitter and receiver Modules. The ir based sensor detects the head movement and provides the information to The microcontroller (on board computer) and the controller judges whether the instruction is right Movement or left movement instruction and controls the operation respectively.
