Tongue Motion Controlled Wheel Chair

Abstract

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 the tongue using tissues adhesive and tongue piercing. As a result of tongue
movement magnetic field generated by a 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 sensor's output are
wirelessly transmitted to the microcontroller and microprocessor will process the signal to control the
movement of power wheelchair. This technology provides faster advanced smoother and more convenient
control..
