Expressing Observation Direction through Face and Body Rotation in a Multi-user Conversation Setting
In this paper we clarified the range of observing direction by rotating the 2D human image and it is possible to express the observing direction by face direction. We conducted two subjective experiments about direction expression of the person on an image. In the first experiment, we compared two types of human image expression, rotated 2D human image of rotated 2D and direction correct. In the second experiment, we evaluated the effect of human image rotation and the criterion for judging the direction. We showed that the direction of the user’s face is the main factor in expressing the observation direction. Results clearly showed that it is possible to express the observation direction, which is required for effective communication, by using only the rotation of human facial image.
