TACTILE ULTRASONIC DEVICE AND METHOD FOR PROCESSING A USER INPUT USING THE SAME

A tactile ultrasonic device and a method of processing a user input by using the same. The tactile ultrasonic device may include a plurality of ultrasonic elements including a first ultrasonic element and a second ultrasonic element, which are placed such that beam axes are not parallel to each other. The tactile ultrasonic device may also include a processor that controls vibrations of the ultrasonic elements. A first focus of the first ultrasonic element and a second focus of the second ultrasonic element may be formed within a specific range of a tactile sensing area.
