A Collaborative Virtual World Application to the Hyper-Interaction Platform
摘要
We present a hyper-interaction platform which integrates several techniques, including motion tracking, motion recognition, a motion reaction control mechanism, and a high precision 3-D model of the International Space Station. The goal is to build an interaction platform for trainers to navigate in a virtual reality. The platform can be applied to customized mission training. The system integrated visualization environment, underlying 3-D model, and a human body tracking mechanism. The tracking system will be extended to 3-D coordination reconstruction; thus, behaviors of users can be identified on the basis of Back-propagation Neural Networks. These navigation parameters are used in controlling navigation in the 3-D virtual environment which is constructed of VRML. Another important issue of this system is to define a model for motion reaction. The definition of reaction can be applied to avatars or to the virtual environment. These integrated technologies can also be used in other virtual reality environments.
