    3-D tele-direction interface using video projector



    We developed a direction system for assisting the work in a real world from a distant site. At first, the 3-D shape of the object is measured and sent to the distant PC. A supervisor at the distant site can observe the CG of the object and draw annotation figures on it. The figures of the direction message are projected onto the object using projectors. The worker is free from any wearing equipment, ex. HMD, and multi projectors avoid the problem of occlusion by the worker body.
