Abstract
There are diseases with the disorder in the face although human's face is an important body site with the social role. In this study, it is focused on “patient's facial expression” as a medium supporting communications between the patient with facial disorder and the doctor toward the satisfaction improvement to the patient's treatment on the medical treatment site. And, “expression to be expressed” and “difference between the expression actually expressed aiming at the expression to be expressed and the expression to be expressed” were selected as information transmitted through patient's expression. The design and development of an interface with the functions of an expression setting and an expression confirmation were carried out as an environmental setting for the patient to express selected information. Fourteen dentists in total who had the treatment experience of the facial disorder evaluated the possibility of the proposed interface as utility and a communication tool in the medical treatment site. The possibility of leading to the expression of the expectation for the patient's treatment was suggested as the results of the experiment, and concrete challenge points and the method for use in the medical treatment field were proposed.
