Tongue driven wheel chair for spinal injury patients

The spinal cord injured patients has no way to move their hands or arms so they need alternative way to interact with the world. In fact in US itself nearly 3 lack people have injuries in their spinal card, hence in order to help those patients the electrical engineers of the university in Atlanta developed this tongue based system. This system helps the patient in controlling the wheel chair only with their tongue along with the headphone and a 5-millimetre-wide magnet attached to the tip of the user's tongue. The two sensors in the head phone will track the movements of the magnet and read the fluctuations in the strength of the magnetic field as the tongue moves. This will be transmitted as signals to the computer where the interpretation and action takes place. This system not only helps the user in moving wheel chair rather by moving the tongue in predefined patterns it is possible to control the cursor in the screen or switch on the TV and play video games.
