ays to create a 'Cave'. An early implementation was called "The Closet Cathedral" for the ability to create the impression of an immense environment. within a small physical space. The Holodeck used in the television series "Star Trek: The Next Generation" is an extrapolation of this technology.A variation on visualizing complete computer generated worlds is "Telepresence". This is a technology that links remote sensors in the real world with the senses of a human operator. The remote sensors might be located on a robot, or they might be on the ends of WALDO like tools. Fire fighters use remotely operated vehicles to handle some dangerous conditions. Surgeons are using very small instruments on cables to do surgery without cutting a major hole in their patients. The instruments have a small video camera at the business end. Mixed Reality Merging the Telepresence and Virtual Reality systems gives the Mixed Reality or Seamless Simulation systems. Here the computer generated inputs are merged with telepresence inputs and the users view of the real world. A surgeon's view of a brain surgery is overlaid with images from earlier CAT scans and real-time ultrasound. A fighter pilot sees computer generated maps and data displays inside his fancy helmet visor. ...
