There has been a lot of talking about VR recently, and with good reason. There's a lot of exciting things happening all across this emerging tech market, and every company wants to participate in the action. Google's Cardboard VR initiative is simple and possess to get a taste of the VR experience, while the HTC Vive plan to take it to an entirely new place later this year with SteamVR.
You seriously should not compare Cardboard to Vive, since that requires a serious gaming PC and the other works with just about every smartphone available on the market, but when you look at the headsets side by side you can see how much they all have in common.
The first thing you'll notice with all three of these devices side by side is the sheer size of the lenses in the HTC Vive compared to the other two. A big part of the VR experience is immersion, which basically means the lenses work with the display to fill your field of view and give you the sense that you're somewhere else ie it acts as a virtulization. It's widely believed the best immersion experiences happen when you go beyond a 100-degree field of view, but HTC demonstrates there's a little more to it than this. Version 2 of Google Cardboard offers a 100-degree FoV, and Samsung's Gear VR offers a 96-degree FoV, but neither of these experiences fill your vision quite like Vive.
That extra 10 degrees isn't all there is to this equation. Where Samsung and Google rely on a widescreen presentation through a landscape smartphone, Vive on other hand,uses a pair of 1280 x 1080 screens in portrait to fill your eyes.
It's interesting to think about where we will be in a year, where there are distinct categories of VR with different levels of content and multiple experiences that are all equally impressive. Cardboard and Gear VR are clearly the entry level, and are used everywhere answer, and that is only going to continue to grow in popularity. Meanwhile, by next year, there's going to be this other category of high-end VR setups that rest next to gaming PCs and offer a reality-altering experience to those who want it.
