Artificial reality

Artificial reality is a book by Myron W. Krueger about interactive immersive environments (or virtual realities), based on video recognition techniques, that put a user in full, unencumbered contact with the digital world. He started this work in the late 1960s and is considered to be a key figure in the early innovation of virtual reality. Artificial Reality was published in 1983 and updated in Artificial Reality II in 1991 (both published by Addison-Wesley).
