Valve will be showing off new virtual reality demos next week in San Francisco during the 2016 Game Developers Conference. The demos will almost certainly be using the HTC Vive headset which the smartphone company has developed in partnership with Valve and its SteamVR platforms.

Valve's brief email announcement on the demos is as follows:

Valve has announced plans to debut "The Lab," a compilation of new VR experiments, at next week's Game Developers Conference in San Francisco, CA. Set in a pocket universe of Aperture Science, "The Lab" offers multiple ways to enjoy room-scale VR. It will be offered free of charge via Steam this spring. More information will be made available next week at GDC."

Aperture Science is, of course, the main setting for Valve's popular Portal series of puzzle games, which has already been used in at least one SteamVR demo.
