Recently, the touch screen have been widespread in the field of computer interface. Use of the touch screen is easy because of intuitive operation. But an operational mistake may be caused due to lack of tactile feedback. In order to solve this problem, several studies have been conducted with various systems. We developed a tactile display using a sheet-like ultrasonic transducer (SUT) for providing tactile sensation. However, in previous research, representation of tactile sensation on the SUT mounted on a large-sized touch screen was difficult. In this paper, representation of tactile sensation on touch screen which is larger than conventional one is reported.
