Abstract
A method may involve controlling an apparatus to transmit a first ultrasonic wave by sending first electrical signals to a plurality of separate electrode elements proximate an ultrasonic transceiver layer. The method may involve receiving first electrode layer signals, corresponding to reflections of the first ultrasonic wave, from the electrode layer. The method may involve determining, based on the first electrode layer signals, a location of a target object in contact with the apparatus. The location of the target object may correspond with a proximate electrode element. The method may involve controlling the ultrasonic transceiver layer to transmit a second ultrasonic wave by sending second electrical signals to the proximate electrode element and for receiving receiver pixel signals from at least a portion of the plurality of ultrasonic receiver pixels in an area corresponding with the proximate electrode element.
