In this study, we develop a robot system which can measure the amount of attention of the audience. The amount of attention is measured from the direction of the face and body of the audience. Direction of the face and body are detected by a distance information and image from the kinect sensor. The amount of attentions of the face and body is calculated respectively using Bayes' theorem. The amount of attention of the audience is calculated by the synthesis probability of the face and body.
