Most serious accidents and injuries often end with various motorist disabilities usually resulting in a limited control of the muscles of various body parts and in some worst case scenarios even the whole body. Tongue driven system is a new wireless assistive
technology which is used for handicapped or it is specially designed for paralyzed person. Tongue driven system consists of Hall Effect sensor. Tongue driven system provides people with minimal or no movement ability in their upper limbs with an efficious tool for environment control. Tongue driven system consists of an array of Hall Effect magnetic sensors and permanent magnet which is held on tongue using tissues adhesive and tongue piercing. As a result of tongue movement magnetic field generated by magnet that will vary around the mouth. These variations are sensed by an array of magnetic sensor which is mounted on the headset outside the mouth. The sensors output are wirelessly transmitted to the microcontroller and microprocessor will process
the signal to control the movement of power wheel chair. This technology provides faster advanced smoother and more convenient control
