This week, hardware maker HTC and PC game technology company Valve demonstrated theirs, called Vive, and it was met with wild rapturous applause from tech writers.
But how is it any different than Facebook's Oculus? And what about those Microsoft goggles that their CEO is calling "the new desktop?" And whatever happened to Google Glass?
We thought it might be helpful to get an overview of all the different virtual reality and augmented reality headsets that companies are building and showing off.
Who's behind it? The hardware is made by HTC, best known for its phones, but the underlying technology is made by Valve, which makes very popular platforms for video games.
