1. An ultrasonic user interface device, comprising:
a transmission unit configured to transmit a first ultrasonic wave toward an internal tissue of one of an arm part or a leg part of a user;
a plurality of reception units configured to:
receive first movement information, wherein the first movement information is based on movement of at least one of the arm part and the leg part; and
receive one of the first ultrasonic wave based on the transmission of the first ultrasonic wave through the internal tissue or a second ultrasonic wave based on reflection of the first ultrasonic wave on the internal tissue, wherein the plurality of reception units surrounds one of the arm part or the leg part in a circumferential direction of one of the arm part or the leg part; and
an acoustic matching component configured to deform the ultrasonic user interface device to a shape of a skin surface of one of the arm part or the leg part.
