 I know kung fu. Crap, go ahead and cut. In spite of all the progress in VR over the last 10 years, there's still one fatal flaw breaking the immersion. No matter what I do, even with the knuckles controllers where I can open my hands entirely, I am always acutely aware that I'm just a guy in my living room in my underwear, waving around plastic phalluses. Now, there are companies out there that make finger tracking glove style controllers, but they cost anywhere from hundreds to literally thousands of dollars to purchase. But one man has risen, not high mind you, and said, that's too much! And he has made a product that you can make for yourself for just $60. $60, really? Yeah. And that's a thumbs up. Yes. I get it. That's good. You know what else is good? Our sponsor. Build Redux. Build Redux offers competitive pricing compared to building a PC yourself.

With me today, I have two exciting things. The Lucid Glove Prototype 4, which does things I have just never seen before. It offers hand presence in VR through the use of a bolted on Vive Tracker or Oculus Quest 2 controller. And it actually offers not only finger awareness, but through the use of servos tied to strings. It offers you the ability to grasp items in VR and feel force feedback on your individual fingers. The other thing I have is its creator, Lucas. Hello. Lucas, talk to me. Start with why. Is it for sex things? It's primarily right now for games, for VR games. Sex games? For fun games. Are sex games fun? Why do we want hands in VR? Well, so a big part of being able to interact with objects in games is being able to go and actually grasp them. But so when you're actually holding a controller in your hand, you're just grasping the same shape every single time on this controller. But so now what you can do is use your hands as if there was nothing in them and then actually be able to pick things up and interact with them. Now you've clearly gone through multiple revisions to get to the stage you're at today. Do you want to talk us through it a little bit before we get into the crazy demo we're about to do? Yeah. Yeah, so this is pretty rough. It didn't really survive the shipping. This was prototype one. This was the one that went viral on TikTok and it broke a lot, but it worked well enough at the time to get, you know, kind of the information that I needed to make them better. You've gone from sort of a parallel aligned spool to a perpendicular aligned spool. You've got what's clearly a much more robust system for wire management or line management. What else have you learned? So moving on to prototype two, namely this is the first one that didn't catch on fire. But on top of that, this one was much better at actually, you know, like fitting on your hand and staying there. And this is the first time I actually had it working inside of SteamVR games. Prototype three. This is when I started messing around with adding wireless capabilities to it, getting the finger tracking really consistent, and getting it a lot more comfortable. And prototype four. Yeah, so this is the one that added haptic support, as well as much better mounting for everything, like the controllers, so that it stays all in one piece. And it's still wireless. I'm assuming the battery is in here. No, so the battery is external, and we're going to be using this to power it for now. So what is in here? So in there, that is actually all of the wiring in order to get this board to connect to all of the rest of it. A lot of it could be done without it, but I did it this way so it's easier to switch out parts and test things. Got it. And this is the emergency stop button, I suppose. That is the calibration button that we're going to use to make it so that it actually matches your hand. Is it okay that I just press that? Yeah, you're fine. I like big red buttons. Let's go try it. Wow, Lucas, this feels just like a plant. I could swear I'm holding an apple. And if you told me that this was an actual genuine Alpaca Blend pillow from LTTstore.com, I'd believe you. All right, so we are going to hook you up here, and we're just going to test all the motors on your fingers. So you should feel resistance on your fingers, right? Oh, I definitely do. Great, great. And then it's off. Okay, that's on. Yeah, okay, that's definitely on. You know what it feels like? It feels like the opposite of like, have you ever had someone like push on your tendons and close your hand? It feels like the opposite of that. Like it's holding my fingers open, you know? Yeah. Okay, but I can't move them at all right now. That means there's a big thing in your hand. Got it. So I'm holding like a big... Choose your words carefully. Grapefruit. Basketball. Cantaloupe. Yeah, cantaloupe. I'm holding a big cantaloupe. Yvonne, if you're watching, it was definitely a cantaloupe. All right, now let's put it into Bluetooth mode, and we will hook it up on the computer. Okay. Okay, so are you in VR? I am in VR. What do you see on your left hand? VR. You don't see it left hand? Oh, no, I don't see it left hand yet. So we're going to turn on the Vive Tracker. Oh, oh, whoa, hey. It started a little. Whoa! There's one not working. That's really, really unfortunate, you guys. Hey, there it is. Now this has just opened and closed. That's it. There's touch sensors on the controller. But this, that is so crazy. Okay, what's next? Okay, and now try to grab a cube and see how it feels. A cube. Or anything. Ah, geez. Okay, so as I get into range, the servos kick in. Yep. That's to prevent latency in actually grabbing it. Oh, okay. Geez. Are you okay? Yeah, I'm fine. It just tripped me out a little bit. Like I finally managed to pick it up and it just like, oh, it like, whoa. Okay, where are you? Oh, I have your balls in my hands. What is your plan? I really want to do anything I can do to make these gloves as accessible as possible. Right now, the best way I can do that is by open sourcing the project and having people build it themselves. But at some point, if there's a way that I can make the gloves accessible to people who don't have a 3D printer or can't build their own gloves, then I really, you know, at some point definitely want to go down that route. So you'd say you're weeks away from final product shipping? Oh, yeah. This one might only work for like five seconds because it's not as built. Oh, yeah, but it'll be the best five seconds of Linus's life. I knew it was a sex thing. Whoa, are you getting this, Brandon? Yep. That's freaking awesome. Okay, the left one's a little, yeah, it's doing stuff. But the right one is like, whoa, look at that. Can you see this? That's crazy. Whoa. That. Okay, that's cool. Oh, it's thin. Okay. That is next level. So do you have a plan to debulkify it a bit? Yeah, that's actually my next prototype, my prototype five. I'm planning on shrinking it as much as I can, maybe moving some stuff up the arm, and also trying to make it as durable and reliable as I can. Oh, cool. Oh, what? Okay, get over here. I get this, get. Oh, that's so cool. I can turn dials. This thing is absolutely nutty. I am very looking forward to seeing the next prototype, which is apparently going to be smaller, more durable. You were saying people in the community have even built ones that are like better than yours. Totally. I mean, people have taken this kind of reference design and modeled their own versions off of it. That is absolutely incredible. And you're still in school, I guess. Yeah. Man, what was I doing at your age? A lot of Counter-Strike source. I'm not even good at it. What I am good at is telling you about our sponsor.
