Hi, this is Wayne again with a topic “Virtual Reality: Explained!”.
Hey what is up guys mkbhd here – and this is a virtual reality – headset, it’s a pretty simple one, obviously, but that’s what it is, and the idea of virtual reality is just that. It’S to replace your reality with something some new virtual computer generated environment and it could be some game or some environment. You walk around or some video, that’s playing all around you when you look around, but the idea is to trick your brain into thinking that that’s your new reality, so vr started with the air force actually as part of their flight training program and it’s flight. Sim. Now, obviously, that’s much easier and cheaper to have new pilots practicing stuff like fighting maneuvers and shooting things and ejecting and crashing all without shooting and ejecting and crashing actual million dollar planes. So that’s where vr makes perfect sense.
Now, in 2015, companies are making these personal vr experiences that you can just buy and use for your own entertainment. All you have to do is just put it on your face, so they do this by taking over your site. So, just like, we use headphones to completely take over a sense of sound. This headset totally takes over your vision inside this one. Google cardboard is a pair of lenses and a place to hold your smartphone, which becomes your screen and your vr engine. Now there are actually two kinds of vr headsets type 1 is the accessory that you plug your smartphone into that becomes the screen, so something like google, cardboard or samsung’s gear, vr and then type 2 is the standalone unit. That does everything it has a gyroscope and the screen and everything built in.
So that would be something like oculus rift or htc’s vibe. Both types, of course, have these lenses that help your eyes focus on the stereoscopic image. That’S right up against your face, which isn’t great for your eyes by the way but whatever, and they all have this gyroscope and accelerometer – that help track your head movement and that’s what helps put you in your own little world.
So i got to take a closer look at one of the second type at mobile world congress this year the new htc vive – and this is something people are getting really pumped about. It’S a prototype for now and the final version might not look exactly like this, but it’s an entirely self-contained vr headset that you can just pick up and put on your face and be immersed. Of course it’s a little more complicated than that, but you have all these little dots around it for sensors, so you actually need to set up little sensors around you uh to track your head in 3d.
Space oculus rift also has some similar looking sensors for the same reason, it’s tracking your head, so on one hand, that’s going to be awesome for immersion the more accurate these sensors can be the more closely it’ll mirror your head movement. So since you’re in 3d space, you can literally move your head forward and peek around a corner which is pretty awesome. But on the downside that does require having a little bit more space to actually set up. Your vr experience, which sounds kind of like a pain and also the thing people forget, is you also need a set of cables to connect this vr headset to your computer, so plenty of people did demos without plugging it in but you’re, not exactly untethered, when you’re Really using it now that first type of vr headset that uses your phone as the vr engine and the screen is actually a little bit more simple.
Your phone already has a gyroscope and an accelerometer built in. So all of your movements around that 3d world will come from that, but these don’t have the advantage of sculpting the optimal vr experience. I mean it’s kind of like an accessory and it’s a little bit weird to like clip your smartphone into some crazy. Basically oversized case and then strap it on your head, but the experience can often be almost as good as one of the dedicated headsets, at least to a vr noob like me, but look making a vr headset right now at least a good one is really hard.
There are so many things you have to consider the the pixels per inch of the display, since it’s right up against your face and it’s magnified and then there’s the field of view, since you want it to be as immersive as possible and the pixels per degree. Since everything’s magnified and so close to your face, there is good hope, though. I’Ve never seen an industry go so fast from zero, like almost nothing to five or six major players. So fast you’ve got oculus rift.
You have samsung gear vr, you have. Google cardboard’s been out for a year. Htc vive is on its way. It’S coming sony project morpheus is also coming.
I would actually even say that microsoft hololens, although that headset from microsoft, that everyone’s talking about the experience of is not virtual reality, that’s actually augmented reality. So virtual reality and augmented reality are two slightly different things, so to clarify virtual reality is replacing your entire reality, so you’re immersed in this new world, with nothing left from the real world, augmented reality is just that. It’S augmenting your reality a little bit. It’S adding some things and combining it with the real world and oftentimes that’ll, be in the form of an overlay or seeing something on top of a real world object.
Google glass also does the same thing, so you can have useful information sort of in the corner of your vision, not totally virtual reality, but some neat augmented reality tricks, but what really separates vr and what makes it so impressive is the immersion factor. The fact that you’re totally in this world so just like with headphones on when you can’t really hear anything else other than the music you’re listening to with a vr headset, you’re, essentially blindfolded and put into this entire new world, with whatever the artist makes virtual reality. Content will take off when there is a lot of virtual reality stuff to look at like 3d. Tv would have only made it if people everywhere started making 3d videos now.
Obviously that didn’t happen and there’s a risk that virtual reality might not ever happen too. Because of that, but i think there’s at least something special here that 3d tv might not have had. I think the first time someone sees a 3d tv that works really well, the reaction might be oh wow, but the first time someone sees like oculus rift or gets a really good virtual reality. Demo they’re like wow. This is impressive. That’S what makes it so cool! So uh yeah the next time you’re, considering whether or not virtual reality will become a thing or not think about what would you do with it? So, thanks for watching i’ll talk to you guys, the next one peace .
