"Virtuality" was the type of thing you mention.
This was a system driven by an Amiga 3000 computer (obviously with some custom hardware).
The problem was, the helmets were rather heavy for prolonged use, and a little too cumbersome. Motion sickness couldn't be ruled out, either. I tried it out once, thought it was awesome. In the home, it would be very easy to knock into things whilst wearing it!
More modern 3-D displays rely on other techniques. For the home, LCD-shutter glasses have enjoyed 2 loads of interest, and the 3D "no glasses required" LCD panels are available albeit at high cost.
For professional use, there are some amazing solutions out there.
SEOS are one of the global leaders, check out some of the stuff on their website. They generally rely on rear-projected screens, using two polarised projectors for each side, and polarised glasses.
