The document describes a Tongue Driver System (TDS) which is an assistive technology that allows users to control devices through voluntary tongue motions. It works by detecting the movement of a small magnet attached to the tongue using magnetic sensors placed in the mouth. The signals from the sensors are sent wirelessly to a microcontroller and used to assign specific tongue movements to commands for operating wheelchairs, computers, phones and other devices. The TDS provides an alternative control method that does not require the use of hands or feet and could help people with disabilities.
