CNET News Video: What can you do with a Leap Motion gesture controller?

2:27 /

The Leap Motion controller for desktops and laptops is now available. Though many have visions of "Minority Report," the technology is much more about precise finger and hand movements than sweeping body gestures. Leap Motion's Eric Lau talks about the "secret sauce" and demonstrates what the device can do now that apps have been created for the 3D, nontouch experience.

It's two cameras, three infrared LEDs, USB controller, those are the major components. The actual hardware itself is fairly simple. It's all off the shelf components. All of our IP and all of our secret sauce, so to speak, is in our algorithm in our software. We track all ten fingers. It's very precise and very low leniency. CNC, that's actually the raw data and the top right hand corner in millimeters, it's a very, very fluid movement using the leap controller in Google Earth. There's a sweet spot in the middle where if I hold my hand, the earth doesn't move and if I move it downwards, it swims down. If I go upwards, it goes up and you can imagine you know, you can do all of this with a keyboard and mouse but you know, you wouldn't be able to do it nearly as fluently and as easily as you can with this controller. It sounds like a music finger dancing puzzle game, you know, there's no other good way to explain it than just to play it. The goal is to hit these little dots here and you kinda have this line that's connected by your two fingers and you can see what this game, you know, how responsive it is. It's based on the latest movie Wreck-It Ralph and it's, you now, if you ever watched the movie, there scene with race, you put your hand here, put your hand here like you're holding a wheel and then you're sensory driving. You can use Leap Motion controller to explore anatomy and learn different body parts. So, this is the skull right now, oh, I'm trying to piece everything back together again and then I can grab different pieces. So, this is called Block 54, essentially our block stacking game, just like a game of Jenga, you're essentially really pulling blocks apart in 3D space. But you're really pulling off the blocks just like you would in real life. So, this is kind of like a 3 brick breaking game. So, you can push this forward. You know, it tracks even the angle of my fingers so I can really direct where I want to go. So, this is a Space Exploration app that's in our store called EXO-Planet. And essentially, you can use the lead device to navigate and explore the universe. So, you can see it captures every little movement as I go.
