The imseCAVE is a full body immersive and interactive visualization system that provides extremely vivid stereoscopic views of sceneries in 3-D designed. The system is developed based on the technologies of distributed and interactive virtual reality, with real-time motion capture capability.

The imseCAVE is originally designed and developed by the Department of Industrial and Manufacturing Systems Engineering, The University of Hong Kong. It is a low cost, high-performance virtual reality system that is versatile and powerful for cost-effective design, analysis and evaluation of complex engineering systems and operations; e-training and e-learning.

In practice, the system can be readily configured quickly to provide an immersive virtual environment for users to obtain firsthand experience of such environment without the limitations of time and space. The system can also be used for training and skill evaluation, a tool for complex system analysis and design such as in the development of products, buildings, and other facilities. In addition, user interfaces such as data gloves, trackers, joysticks, motion platform can be readily connected to the imseCAVE for enhanced immersiveness and interactivity of the virtual environment.
