Because something to think about and conversation with someone disturb the attention to the car driving, decentralization of attention by the cellular phone call tends to decrease safety in driving. This paper presents an experimental result of the relation between the attention concentration on the cellular phone call and the change in the facial expression such as eye movements and blinks. Moreover, this paper describes a method of detecting the depth of the attention concentration from the facial expression change.
