History of video games/AR

Prototype Technology of the 1980's and 1990's
During the Cold War there was a massive amount of Research and Development ongoing by both government and commercial agencies, which had a side effect of trickling down to consumers later, namely in Augmented Reality, and general advances in computing. During this time, a number of marketing attempts to promote the technology would be made. Though this technology would not see consumer use in the 1980's and 1990's, it would form the basis for common gaming technologies decades later.

HUD development greatly influenced AR development
