Abstract

With the popularity of cameras and rapid development of computer vision technology, vision-based HCI is attracting extensive interests. In this paper, we present a system for controlling avatars by natural body movement via a single web-camera. A pose database and a set of color markers are utilized to make ill-posed vision problem tractable for real game applications. Based on the proposed algorithms for indexing pose samples and estimating human pose, we build a prototype system that is responsive, easy to manipulate and runs automatically in real time. User study shows that the system is user-friendly and provides immersive experiences.
