Development of VR experiencing system with hemi-spherical immersive projection display for urban environment design

This paper introduces a VR experiencing system for construction planning and design of urban development in advance. The characteristics of the developed system are equipped with two different size of hemi-spherical screen display and supplying the circumstance that several users can share the VR space at the same time and design it cooperatively. By using the system, it is possible to show the simulation results about strong wind blowing around the buildings, diffusion of a poisonous gas under fire accident, and evacuation using hundreds of humanoid models. Also some kinds of haptic device are combined to expand the functionality.
