Abstract

We have proposed FAIRVIEW, a framework for realizing 3D graphics-based interaction between mobile users in real world and remote network users. In order to realize FAIRVIEW in an ordinary wireless LAN and Internet environment, a QoS adaptation mechanism is essential. The QoS adaptation mechanism of FAIRVIEW regulates, for each user, update frequency of his/her observable objects depending on the importance values associated with regions of his/her sight within available bandwidth. In this demonstration, we show how our QoS adaptation mechanism changes the quality of each observable object as the user moves his/her sight.
