 So we're checking out here with Maxus Tech. You have a little device right here. Yes. And something magic is happening. What's going on here? Hello. So who are you? Hi, I'm Kelvin. And this is our first product. It's called a Wella. And it can turn any surface, just normal table into smart interface. And see, I put my device over here and I can just, it can just track my fingers movement. It's not IR? No, it's not IR. It's ultrasound. Ultrasound. Ultrasound. Yes. It's making a layer and you're closing it? Actually, it's sending out some sound wave. But ultrasound means you cannot hear it. And it can be reflected by my finger and be received by the sensor. So you can actually, you don't need to touch? It works? Yeah, you don't need to touch. You don't need to touch? Yes. But touching only makes some active feedback makes you feel comfortable. Is it very precise? The resolution is around 10mm. 10mm? Yes. So it's 1cm? Yeah, it's enough to control some IoT devices. I demo over here. So what is this one doing? This one, I stick my gadget to the wall. This is normal wall. And then I can control it to play some music. I like that sound. And if it's not sound, it's not big enough. I'll just turn up the volume. I turn it down. Yeah, you can see that. And if I want to control the, I can control the light at the same time. It's okay. I can just roll the L. You can recognize my letter. And then I can control my lights. You see? I can turn it off. Yeah. It's gonna be simple. So you can go music? No, the music is called S. S. A speaker. Yeah. I can go next song? Yeah, you need to slide away. Slide away, okay. This is awesome. Yeah, you need to use this. This is more natural. So either you don't have to... You can even work without touch or it's better to touch? It's better to touch but you can work without touch. And you can do it like this? Yes. Nice. So this is on Kickstarter? Yes, it's on Kickstarter. We are 22 days to go. And it's already successful? Yes, our goal is 20K. It's called a Welle. Welle. It's a German word. Welle, it means super. It means wave. Wave? Yes. Nice. And this is your video on Kickstarter? Yes. How long is the battery on this ultrasonic Welle? It can last up to one month. One month? Yes. And it's just always standby and you have to start it or... Any time you come for normal case it will be in sleep mode. And once you put your finger inside you're going to be detected and it just won't wake up and do the functions. Nice. You can just like gently Nice. People are going to start touching their walls and tables much more now. And it's possible to buy more than one? Sorry? It's possible to buy more than one? Some customers buy 10 or 5? Yes, some of them buy 3, 5 sometimes. Because they want every wall, every table? Maybe like Welle in my room.
