Abstract
An intraoral controller senses electromyographic signals within the oral cavity which are produced as a result of movement and contraction of the tongue muscle. Active and reference electrodes pairs act as sensors for electromyographic signals which are processed into control signals. The electrodes are mounted on a substrate within the oral cavity. Signals from the electrodes are transmitted by telemetry or by wires to an electromyographic signal processor which is connected to a device to be controlled.
