Multi-Layered Hierarchical Bounding Box based interaction in virtual environments

Abstract : Interaction techniques play a vital role in the success and effectiveness of a virtual environment. Therefore, researchers have put much effort on the design and development of easy, realistic and intuitive interaction techniques. In this paper we present a new interaction technique specifically designed for educational environments. The technique uses a step by step and hierarchical approach to have information rich, selection/ manipulation and exploration of an object and its constituent parts (objects). The technique is implemented and evaluated in a virtual environment having a human skeleton designed in 3DS max. Subjective evaluation reveals that the technique is very useful and suitable for educational virtual environments.
