Methods for gesture recognition and control

An electronic device for gesture recognition, the electronic device comprising:

• a radar transceiver;
• and
• a processor operably connected to the radar transceiver, the processor configured to:
• detect a triggering event,
• in response to detecting the triggering event, transmit, via the radar transceiver, radar signals,
• classify a gesture from reflections of the radar signals received by the radar transceiver, wherein the gesture is classified as (i) a first gesture type when the gesture includes at least one repetition in a feature domain, (ii) a second gesture type when the gesture is not repeating in the feature domain, and (iii) an invalid gesture when the gesture is not classified as the first gesture type or the second gesture type,
• when the gesture is not invalid identify the gesture based on a comparison of an angle shift to a first threshold and a power level change to a second threshold,
• determine whether the gesture indicating a potential action is associated with the triggering event, and
• in response to determining that the gesture is associated with the triggering event, perform an action indicated by the gesture, and
• in response to determining that the gesture is not associated with the triggering event, do not perform the action indicated by the gesture,
• wherein the feature domain includes at least one of Doppler, velocity, angle, and range.
