Abstract
Recently, the touch panel has been widespread as computer interface. Using the touch panel is easy because of intuitive operation, but it is difficult for a visually impaired person who cannot get the visual information. In order to improve this problem, tactile display using sheet-like ultrasonic transducer has been developed in previous research. By this device, when a touch panel is operated, user can get tactile feedback, and it is possible to recognize an icon and a window. However, at the present stage, it cannot be mounted on a large-sized touch panel. So, we aim at development of tactile display using sheet-like transducer which can be mounted on a large-sized touch panel. In this paper, evaluation of the couplant used for the sheet-like ultrasonic transducer is reported.
