Accuracy for the validation sequence pre- and post-conversation. (a) The calibration was followed by a validation sequence on the face of the conversation partner. After a conversation of about 17 min, another validation sequence was added. (b) Accuracy for the different facial target locations in degrees visual angle. Black lines represent mean values. Lower values represent better accuracy.
