Abstract
Recently, many interactive systems that talk with CG characters using voice recognition are proposed. However, in the traditional interactive systems, there is a problem that the interval of conversation is unnatural since processing of voice recognition is slow. In this paper, therefore, we propose a technique for generating reactive attention based on user's nonverbal information and a conversation status.In order to realize our technique, we first get verbal data and 3 nonverbal data of a user. And what CG characters pay attention to is decided on those parameters. Then, attention of CG characters is generated by attention angle shearing mechanism. An example of a conversation with CG character using our technique demonstrates the effectiveness of adding attention of CG characters to interactive systems.
