In this study, we examine a method for guiding the users' hands to a specific region in the air, by utilizing Airborne Ultrasound Tactile Display (AUTD). The AUTD is a device that creates focused airborne ultrasound on the surface of human skin resulting in perceivable vibrotactile stimuli. Measuring the position of a hand in real time, the fabricated system allows users to tactually feel a virtual wall out of focused ultrasound that is accordingly generated. The AUTD is placed on the left side of the workspace yielding rightward radiation force onto the palm of the user. In this paper we particularly discuss the human performance of locating horizontal position displayed by the system, in terms of its accuracy.
