Abstract
Methods and devices for detecting movement of an object includes: receiving a first set of output signal values and a second set of output signal values from a sound wave receiver, each output signal value in the first set and the second set being representative of amplitude of an acoustic signal reflected from the object; determining, based on the received first set and second set, a difference set including one or more difference values, each of the one or more difference values being representative of a difference between a first output signal value in the first set and a second output signal value in the second set; determining whether the difference set satisfies a predetermined condition based on whether each difference value of the difference set has a magnitude exceeding a predetermined threshold; and outputting a motion detection signal if the difference set satisfies the predetermined condition.
