The gaming industry has continuously tried to pump up the entertainment quotient of their products by making them more realistic, Purcher observed. The industry moved from 2D to 3D animation. It improved the resolution of game graphics. It pumped up sound effects and made game controllers more natural. Immersion is the next step in the evolutionary step in that development timeline.

"I could remember it being so dramatic when gaming shifted from the CRT to HDTV with 1080p," Purcher wrote. "Games came to life like never before. So the very thought that gaming will one day be able to immerse us into detailed gaming environments by projecting the imagery of the game onto the walls of our room is simply wild."
