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.
