The invisible person

摘要

In this paper we describe an advanced user interface enabling even playing games in an immersive virtual environment. There are no common input devices, users presence in the environment, movements, and body postures are the available tools for interaction. Furthermore, a publicly accessible installation in the Vienna Museum of Technology implementing such an advanced environment is described. In this installation computers are completely hidden, and it is one of the most popular exhibits in the museum, which has been accessed by more than 200,000 visitors since September 1999.
