Abstract: The present invention, in various embodiments, comprises systems and methods for providing a communication system. In one embodiment, the system is an assistive technology (AT) in a single, highly integrated, multimodal, multifunctional, multipurpose, minimally invasive, unobtrusive, wireless, wearable, easy to use, low cost, and reliable AT that can potentially provide people with severe disabilities with flexible and effective computer access and environmental control in various conditions. In one embodiment, a multimodal Tongue Drive System (mTDS) is disclosed that uses tongue motion as its primary input modality.

Abstract: A method of tracking movement, position, or both of a tongue of a subject. The method includes positioning a tracer unit on the tongue of the subject in a non-obstructively manner; positioning a sensor system in proximity to the tongue carrying the tracer unit; calibrating the sensor system relative to the tracer unit; and detecting the position of the tracer unit. An assistive system/apparatus can track movement, position, or both of the tongue. The system/apparatus includes the tracer unit; the sensor system for detecting position of the tracer unit and adapted for non-obstructive placement proximal the sensor system; and a control system for transmitting to a processing system.
