Abstract
Design And Implementation of Advanced Wireless Tongue Drive/Operated System for Paralyzed,Disabled & Quadriplegic Patients.
Highlights
A small permanent magnet secured at the tongue by using implantation, piercing, or tissue adhesives is used as a tracer, the motion of that is detected by way of an array of magnetic sensors established on a headset outside the mouth or on an orthodontic brace interior sent wirelessly to microcontroller by using wireless transceiver
The sensors output transmitted wirelessly personal digital assistant (PDA).The signal processor classifies and converts the sensors output to user commands.The advantage of tongue operated system is that the magnetic tracer giveslots of tongue movements, these movements provided with specific commands
Wireless Transceiver Nordic Semiconductor; nRF2401single chip 2.4 GHz transceiver is used wirelessly transmit the output of magnetic sensors to PDA using ISM band having frequency of 2.4 GHz. [30]
Summary
A small permanent magnet secured at the tongue by using implantation, piercing, or tissue adhesives is used as a tracer, the motion of that is detected by way of an array of magnetic sensors established on a headset outside the mouth or on an orthodontic brace interior sent wirelessly to microcontroller by using wireless transceiver. The device consists of a head set a compact computer and a tiny magnet attached to the tongue, movement of the tongue send the commands to the computer allowing users to steer their wheel chair operate their computers and generally control their environment in an independent way.
