What does a tongue touch keypad utilize for input?

A tongue touch keypad utilizes a dental mouthpiece with switches for input. This specialized assistive technology is designed for individuals with severe physical disabilities who may have limited ability to use traditional input devices. The dental mouthpiece is fitted with switches that can be activated by the movements of the tongue. This allows users to input commands or control devices such as computers, communication aids, or environmental control systems simply by moving their tongue in various directions.

This technology offers a unique solution for individuals who may not have the capability to use their hands or other forms of input effectively, thereby improving their independence and enhancing their ability to communicate or control their environment. The other choices represent different forms of input devices that do not utilize the specific method of input through tongue movements and switches.
