I've discussed VR and AR devices and predictions of their applications in the future several times. Now I've got a brief hands-on with it to review, specifically the Samsung Gear VR.
Other than not quite being able to get it in perfect focus, it was pretty fantastic. There was no visual lag to be noticed, and most of the images were nicely crisp and reasonably 3d. Headset was easy to wear and comfy, and the whole rig caused no headache, vertigo, or disorientation (note: I'm mostly immune to these, your experience may differ).
The interface needs a bit of work, but various controllers and similar are in the works, and even the included touch interface would work just fine were it a personal model I could adjust the settings on. I'd like a bit wider field of view, but dedicated vr sets like the occulus rift will no doubt handle that. It also kind of requires you sit in a spinning chair, at least for the games I used.
VR and AR are technologies that are going places. A bit more streamlining and development and I'd bet they'll be as revolutionary a step as the smartphone was. Presently vr is stuck in a loop of not much development for it because nobody has it yet because nobody develops for it. I'm used to being a late adopter for tech, but i think this is one that's worth it to get in on.
