## Transcript

video, we're going to put it to the test to see if it's actually any good. Hey, that's pretty good. Let's get it. This is Reocap's 15point full body inertial motion capture, which is a bit of a mouthful. It's basically a 15 tracker
kit for full body tracking with built-in sensors, so you don't have to worry stations. So, now that we know what it is, why did it go viral? Well, there's seen recently of a VTuber who left her trackers on when she went to the
bathroom. But instead of losing signal or walking off screen, [music] the exact opposite happened and you could see everything. And that made the internet go wild. People were baffled wondering how'd she do that? What is she using?
bathroom without washing her hands? The last one was a yes. Yes, she did just leave without washing her hands. But her hygiene habits aside, the clip went hand sanitizer. More and more people started posting their own Rebo Cap
moments. The tracker got so much attention that it sold out in mere days. And as of the making of this video, it's still sold out. But I have good news for you because your boy managed to snag some for himself. We're going to put
this to the test to answer one important question once and for all. Can it track you taking a Is [clears throat] it really as good as people make it out to be online? Let's find out. First, let's open this bad boy. See, the special
thing about Revo Cap is that while other trackers like the Vibes require base stations and unwieldy chunks of plastic, all the Reo Cap trackers fit in a container the size of your average lunchbox. But despite its small size, it
packs quite a formidable punch in terms of performance. See guys, size doesn't Let's take a look at what else comes in the box. You have sticker labels. Woo! Yeah, I know. absolutely gripping
stuff. But sarcasm aside, what's actually gripping are these straps that wrap around your body and hold the trackers. They're elastic and actually stay in place really well. No slipping or sliding at all, and they're all kept
nicely in a nice little neat pouch. You also got a USB extension cable, tracker housing that attaches to the straps, a power cable for charging, the coolest measuring tape I've ever seen, and finally a USB dongle that is used to
that wireless experience. While the trackers are compact, setting them up can be a bit of a hassle. Every part comes separate, so you'll actually have to assemble them one by one yourself like you're playing adult Legos. So, put
on some music or a new Zikos video in the background and get cracking. straightforward. Slip the strap through the housing, secure the trackers in your brain rot brain won't forget what tracker is which. Am I speaking from
personal experience? Yes, I am. Also, don't worry about figuring out what tracker to put where because every tracker is labeled at the back. All in all, this took me about 30 minutes to assemble, and once you're done, you
the trackers themselves. But one thing you do need to keep in mind is the strap length. Each strap is measured to fit certain parts of your body. For example, than the leg strap, and the leg strap is going to be smaller than the chest
view Rio Cap's website for more setting these things up. Once you're done, you should put them on like how personally prefer was actually to put them directly on my skin. Scandalous, I
know. I bet you're naked under those clothes. Disgusting. The reason why I won't get in the way of my movements, allowing me to be as free as a bird. >> I'm free. >> Now that we're all strapped up, let's
open up the PC and boot up the Rebok software. There's a lot of fiddly too overwhelmed because I'll show you around the important things that you need to know to get started. The big old viewport here is a scene containing you.
of you, but it's still you. To the left is this diagram of a model with dots on it. The dots represent a tracker and where it should be placed. Mr. Mannequin Man over here is also accompanied by a series of labels and ooh, pretty colors.
I [clears throat] mean, statuses. Statuses. This is the tracker's name followed by their ID, battery status, signal status, and magnet status. If let me give you a very brief rundown and simplified explanation. Revocap trackers
are what's known as IMUs, which stand for inertial measurement unit. This means that no trackers or external sensors are necessary. Instead, it's all combination of a gyroscope, an accelerometer, and magnets. Each part
works together so that each tracker can tell where they are and how fast they're trackers track. But I'm not qualified enough to talk about the science behind have if you're planning to use this is
anything that can be magnetized like screws and iron objects so that you can keep your trackers tracking smoothly. Next, we have calibration, which is additional calibration in the configuration tab. More info on those in
the documentation. Next, we have PC settings. VMC output is how you connect your Reocap software to your desired 3D tracker of choice like VC phase or WO. this little switch here. Lock displacement. Turn it on and you walk in
around. Either way, chat can still see [laughter] I'll stop with a toilet joke. It's just really funny. Okay. Let's get calibrated and see how this thing performs.
>> Calibration complete. >> Okay. Nice. [laughter] Why am I backwards? What the freak is this? I immediately ran into an issue. But it turns out it was not Rebocap's fault. It was my own idiocy. I
basically mixed up my lefts and my rights, even when it was clearly labeled by me. Ah, there we go. Much better. Look, you hands. Of course, I had to try out a few movements to see how well it would track
my entire body, like squats, the Asian squats, and break dancing. I call it break dancing because it breaks my knees. Ah, my knees. I'm not beating the UNK status allegations. It's looking pretty good so far, but it's only in the
looks like with a Vtuber model. So, with a calibration all set up correctly, let's boot up my 3D model and see how it tracks in practice.
not a fanboy. This was the only 3D model I had during the unboxing. Okay, but if you want to see how I made her, I have a video for that that you can watch after this. All in all, I was pleasantly surprised. I was expecting some glitches
and weird pops, but it was all relatively smooth, accurate, and regardless of how fast I went. Battery life was pretty good, too. I ran these active karaoke stream where I did a lot of moving around and also a lot of
dancing. And yet, the battery barely even budged. I even found out that a short 10 to 15 minute charge can bring a tracker up from 0% to nearly 20%, which hours to play with. The trackers themselves were slim and very light, so
I could move around freely. Not once I ever feel weighed down. But with the positive feedback out of the way, let's move on to the bad, the ugly, and the downright stinky. I noticed my limbs, head, and especially entire body would
slowly drift away over time. I suspect that it has something to do with the high magnetic levels around my room, especially towards my feet. I mean, just I don't know about you guys, but this doesn't look very good. [laughter] My
room is quite small, so I didn't have a lot of space to work with. And I'd say where nothing magnetic is within a couple of arm lengths away from you. literally drifting off screen or even looking like I came straight out of The
Exorcist. However, I did find a solution, and that was to automatically reset the origin every two minutes using this. Though, I did wish that it would snapping you back to the origin. Regardless, it wasn't the most elegant
solution, but it was better than literally leaving the screen. And the trackers would sometimes just fix itself without any recalibration or my hand on my on my on my belly, but it's going Oh, okay. There we go. Never
it's going Oh, okay. There we go. Never mind. It fixed itself. [laughter] it works, but it works. But if it ever came down to it, I would spend just a last resort. One last con about the trackers I found was actually to do with
the charging box itself. I'm not sure why, but some of the trackers wouldn't It's like the connection was kind of messed up or something for some of the docks. there would always be at least one left on less charge or even no
battery. I'm still trying to figure it out, but that's certainly something to keep in mind. I'll be honest, when I saw the price of these things, I was a bit skeptical at first. $200 is suspiciously cheap, especially considering that the
main players for full body trackers are way more expensive. Like, a single tracker from one of these staple brands would cost about as much as the entire set of 15 trackers from Reoccap. But I'm glad I gave these a go because I ended
up very impressed with them. And in the end, despite all the silly glitches I actually ran into, I quite enjoyed my time using them. So, if you're looking you've got a decent environment to work with and a little bit of money to spare,
then these might be a great starter option for you. I'm not sponsored, but I interested in purchasing a set for yourself, they're restocking on March 5th, so be sure to keep an eye out. If you want to get started with 3D but
don't know how, maybe you can check out this video next.
