Seamless communication between real and virtual worlds    What kind of technology is it? We have developed a communication environment in which a reflected image (mirror image) of the user is superimposed on an image of a remote location and computer-generated elements in a shared virtual space. Through the use of image recognition techniques, the user can "touch" images of objects on the screen and manipulate those objects. The user can also display information from a remote location without touching the screen. We are investigating and evaluating interface technologies that allow operations to be performed seamlessly between real and virtual worlds across a network.        What are the features? Image recognition technology allows users to "touch" objects and computer-generated images without touching the screen. This technique can be used to implement a shared-space communication environment where physically remote users see the same objects as if they were sharing them. Users in remote locations can present and manipulate shared documents by making them semi-transparent. Users can manipulate objects or display information at remote locations.      What can it do? It can provide: Shared-space TV conferencing systems Remote education systems for remote conferences, counseling, and teaching actions and operations A futuristic presentation tool for exhibitions, show rooms, museums, etc. A touchless interface for information manipulation in public, medical, hygienic, and explosive environments
