A survey on tongue control system

“Tongue control system” is basically controlled by Assistive Technology (AT) which is developed for people who has severe physical disability or paralyzed who want to control/access their environment. The Tongue control system consists of four hall sensor modules placed on the Mouthpiece and the Hall Effect magnetic field is created by placing a permanent magnet on the tongue of the victim with the help of tissue adhesive or piercing. These fields with the help of wireless transmitter is sent to the prototype receiver which the victim wants to control; in this way a victim can control his/her environment using the tongue that works on AT. Finally, the design was tested, and the result confirms the design approach for a healthy subject.
