A Smart Communication System for Avatar Agents in Virtual Environment

This paper propose a virtual communication system for avatar agents using geometry topology. Current virtual communication systems have several problems and limitations since they use only 2-dimensional dialog box and word balloons though they provide 3-dimensional virtual environment to communicate in virtual space. To solve these problems, modern virtual communication systems have developed artificial chatting techniques such as 'One-to-One Chatting' and 'Group Chatting'. We propose a novel communication system for avatar agents using geometry topology information such as distances and directions between avatar agents without artificial chatting techniques. The main contribution of our work is threefold. First, we display 'Partial Talk' and 'Complete Talk' by using geometry topology so that make more realistic and natural conversation without artificial complex communication architecture. Second, we design a greedy algorithm for placing the word balloons in 3-dimensional virtual space. Finally, we propose a method to analyze order of dialogs and to construct talk sequence graph.
