Apparatus for tracking the motion of subcutaneous body parts such as tendons in the carpal tunnel of the wrist by use of an ultrasonic sensor, and supplying signals from such sensor to a computer for comparison with reference data in a memory and utilizing the output of the computer to drive a readout such as a visual display or printing of text corresponding to motions of the subcutaneous body parts such as tendons in the carpal tunnel effected by movement of the fingers as in simulated typing. Alternatively, the movement of other subcutaneous body parts such as facial muscles can be sensed, and signals generated from the sensor can be transmitted to a computer for processing to actuate or control apparatus such as an artificial limb or a motorized wheelchair.
