HyperMirror : a video conversation system which can point at object in partner ' s space

In current video conversation systems, we can't point to objects in the listener's environment. In our HyperMirror system, speaker can point to anything on the screen, even if it is a distant mountain or in the listener's environment. Pointing in HyperMirror, all members can identify the location immediately without misunderstanding because of WISIWYS (What I see is what you see) feature. HyperMirror images are made by optical or electronic synthesis. Though they don't really exist, the correspondence between images and the real world is very simple and understandable to most people. HyperMirror will be useful to remote conversation on physical objects. keywords: HyperMirror, CSCW, pointing, remote instruction, WISIWYS
