While SteamVR is practically synonymous with the HTC Vive, Valve intends it to be an open platform with multiple OEMs. At this year’s Game Developers Conference, GDC 2017, LG was showing off one of their prototypes, which the folks at Adam Savage’s Tested got some time with. The company repetitively said that this is just a prototype that can change in multiple ways.
There are some differences between this and the HTC Vive, though. One change that LG is proud of is the second app button. Apparently, the company found that developers liked to assign buttons in pairs, such as a “forward” button to go along with a “back”. As such, they added a second app button, and placed all three above the touchpad for less accidental presses. The weight distribution is, apparently, also adjusted slightly, too. The difference that Tested seems most interested in is the pull forward and flip up hinge holding the mask, allowing the headset to be moved out of the way without fully taking it off the head, and for it to be easily moved back into place around glasses. (Thankfully, I’m far-sighted, so I can just take off my glasses when I use my Daydream headset, which I assume holds true for other VR devices.)
It’s unclear when it will come to market. Tested speculated that it could happen sometime later this year, which would put it just before when we expect the HTC Vive 2, but… speculation.
