音声対話における視線情報を付加した場の盛り上がりモデルの開発

In human communication, nonverbal behaviors such as facial expression, body movement, eye-gaze, and pupil response play an important role in realizing activated interaction and communication. In our previous study, an activated interaction through avatars was analyzed, and an estimation model for the activated interaction was developed by introducing the concept of heat-transfer engineering. This model estimates the amount of heat in the communication field as the degree of the activated interaction based on an assumption that each talker's heat is transmitted to the communication field. However, it is hard to estimate interactions including the conveyance of eye-gaze because the model has no parameter of the eye-gaze. It is important to share the conveyance of mutual eye-gaze for producing the activated interaction in voice communication. Therefore, it is expected to develop a model that estimates the conveyance of eye-gaze. In this paper, focusing on eye-gaze which plays an important role in producing the activated interaction, we developed a model that estimates the degree of conveyance by the talker’s eye-gaze in voice communication. This model estimates the degree of the interaction-activated communication as heat transfer by combining the speech input and the eye-gaze input.
