In this study, we propose an evaluation method by measuring the reflected ultrasound from the skin surface to examine the accuracy of the focal position. In the proposed method, we assume that the fingertip exists as the irradiation target inside the workspace of the ultrasonic tactile display and evaluate the validity of the presentation based on the received intensity of a single receiving element. In this paper, the reflected wave when irradiating focused ultrasonic waves to a sphere imitating a fingertip is formulated based on a geometric model at first. Then, the received intensity when the focus is scanned is measured by experiments, and the validity of the proposed method is shown.
