아바타 제스츄어 디자인을 위한 상호행위적 신체언어 연구

While the user is creating the message for her interlocutor, her avatar stands motionless or repeats a selected animation sequence in most current graphical chat systems. This fails to reflect the natural relationship between the body and conversation that is taking place potentially giving misleading or even conflicting visual cues to other users. However, if just typing characters can animate the avatar's gesture, the user will be able to communicate more effectively with other users. To address this issue, this study tries to develop a theory of embodied conversational 3D avatars with relying on findings from conversation analysis of human-human conversation. The main non-verbal signals that can be applied to designing avatar are physical appearance, kinesics, and situationality. And the interactive types of bodily non-verbal behaviors are emblems, illustrators, regulators and emotional displays. With integrational semiotic approach, the bodily somatic language is classified into information offering gestures, requesting gestures, emotional expressing gestures, and evaluating gestures. This study analyzes those gestures with the description of gesture representation, relevant verbal expression and possible avatar gesture animation and proposes the chatting system parses the text to get the gestures the user desires to portray, taking in account cues present in the text like: Types of words used, contextual information, length of phrases typed, and use of emotions :-) or :-(.
