Videoplace (1985) by Myron Krueger (via VintageCG)
Videoplace, developed in the mid-1970s, but with work continuing through the late 1980s, was a pioneering creation of full-body interactivity and virtual environments. It contained 25 different environments (or interaction patterns) in which people could engage. He coined the term “Artificial Reality” to describe what he was striving to create.
His work is a clear precursor to such developments as multi-touch, the Sony Eye Toy (2003), and Microsoft’s Project Natal (2009).

WOW! I know it looks dated, but this is 1985 we are looking at, 25 years before we knew about Project Natal.
