Abstract
The "Tongue Drive System for paralysed People” is a tongue-operated assistive technology developed for people with severe disability to control their environment. The tongue is considered an excellent appendage in severely disabled people for operating an assistive device. Tongue Drive consists of an array of Hall-effect magnetic sensors mounted on a headsets on the outer side of head to measure the magnetic field generated by a small permanent magnet secured on the tongue. The sensor signals are transmitted across a wireless link and processed to control the electric appliances which can be operated by 230 v such as, a phone, or other equipment. On the other hand it also controls the movement of wheel chair. The principal advantage of this technology is the possibility of capturing a large variety of tongue movements by processing a combination of sensor outputs. This would provide the user with a smooth proportional control as opposed to a switch based on/off control that is the basis of most existing technologies. We modelled the effects of position and orientation of the permanent magnet on the sensors and experimentally measured them.
