Wall-Sized 3D Displays: The Ultimate Gaming Room @ Tom's Hardware
 

There is a term you may have heard in the 1980s and '90s. It held the promise of the ultimate handshake between technology and entertainment. The term defined an idea that became very popular and actually brushed against pop culture for a time - they even made a movie or two about it. But after its initial surge of popularity, it became obvious that the technology needed to bring this concept into the hands of the public wouldn't be available for some time. The term's popularity waned, and now it's gone out of style. The term was virtual reality.
Virtual reality promised us the ability to explore virtual worlds in a way so convincing to our senses that we wouldn't be able to tell the difference from actual reality. In pop culture, virtual reality was associated with motion-tracking helmets that had 3D displays inside, with the user strapped into a gyroscope so they could move about in the virtual world without actually going anywhere.
