Measurement System of the Interpersonal Proximity using a Wearable Eye-Tracker

In this study, we propose the measurement system of the interpersonal proximity using a wearable eye tracker. The proposed system uses the area occupied by the other person in the visual field, head tilt and gazing at the face as distance indicators. Measuring the interpersonal proximity compares with the measuring the physical distance between the two persons for the development of the quantitatively measurement. In this paper, we conducted a preliminary experiment using the proposed system. Results shows that the ratio of face gazing decreases in the approached participant. The face gazing does not occur when the approached participant in sitting.
