Abstract
A new Communication system for the blind has been developed. The system, named MIMIZU, is composed of a pair of terminals equipped with refreshable tactile graphic display and ultrasonic pen device. Using the terminal, a blind user can make drawings directly as he likes on the tactile surface with ultrasonic pen. The other blind user can recognize the tactile image appeared on the other terminal by touching it. In this way, the system can support communication between blind users by means of tactile graphics. We describe results of simple experiments in which a subject tried to transmit simple drawings to the other subject. The results show difficulty of transmitting a shape of circle without preliminary information because resolution of the display was not enough. However, it is useful to transmit shapes composed of straight lines. And even if the shape is a circle, the user can recognize it when he has information in advance.
