We present a head-mounted device for measuring mutual facing behavior among individuals and representing face-to-face behavior. The contributions of this work are: 1) development of the wearable1 infrared communication device for measuring and representing the facing behavior; 2) an experiment for validating our defined face-to-face behavior (a physical state in which two persons' faces are within ±20 degrees of each other's facing direction); and 3) evaluations of the device's performance (detection range, response time, and comparison with human coder and wearable gaze trackers) in laboratory experiments.
