Abstract: A radar transmit antenna of a head mounted device transmits a transmission radar signal to a face-region. A radar receiver antenna of the head mounted device receives a return radar signal from the face-region. The return radar signal is matched to a selected expression signal included in a plurality of expression signals stored in an expression database.
