Leap is Kinect with 200* resolution? SLAM!


Get yer Dev Kit while its hot.

What technology does leapmotion use (is it imaging? a theramin?)

I'm not sure, but they promise uber-kinect like performance ; ie minority report handwaving;

but ultimately, if it creates a depth map at that size, shape, and cost ($80), it's a SLAM-dunk!

a theramin pronounced "booyawwahhaaeeeeeee'

$70 for something 200* better then connect... damn.  Also it looks like they're giving away free dev kits to get the ball rolling on their hardware. 

How can I get a free developer kit?

We’re distributing thousands of kits to qualified developers, because, well, we want to see what kinds of incredible things you can all do with our technology. So wow us. Actually, register to get the SDK and a free Leap device first, and then wow us.

Already pre-ordered it. Once its shipped I'm sure I'll do an unboxing video.

I saw this earlier and my first reaction was "wow"! At first I wasn't sure if the video was some well-produced smoke-test (e.g. "hey let's see if this goes viral to judge demand before actually building it") but then Google revealed a couple demos, so at least the core essence is there.

No idea on how it works. The inventor of the supposedly "patented" technology is David Holz. A quick search (USPTO website) for patents or published patent applications under his name revealed nothing. It is possible the "patents" could be some peripheral IP they licensed, say to handle the gesture recognition part rather than the basic depth perception.

As for how it works, if I were to make something like that I'd use a combination of stereo vision and structured light. You could probably do the basic processing with a decent ARM, but to get the high spatial resolution they are quoting you need something with more oomph. They are almost certainly not using time-of-flight.

They quote they can measure accuracy to 1/100 mm. That's 10 microns. If true, they probably did that using a lot of hyperacuity say averaging depth information from a region and using the law of large numbers to improve the accuracy.

If this item is real, then it is a game changer.

It came off to me as kinda fake.

Not fake...
I applied for my Dev kit this morning!

Comment by Taylor Cox on May 21, 2012 at 2:44pm

How does it come off fake at all?

I just thought of another possibility- that little box could be just two cameras to make a stereo vision pair. The video processing, depth perception, and gesture recognition could all be done on the host computer. Nowhere in the LeapMotion site does it say all processing occurs in the little box.

If this is the case, then we probably won't be putting this on a quad any time soon.

@Adam- actually the fact you can order a dev kit alone is not proof it is real- that could be just a way to get interest e.g. measure how many people take the time to actually fill out the dev kit application. Startups do this all the time (not that it is entirely honest...)

It seemed vague to me with regards to how it worked and specifications. The site reminded me of Tacocopter. 

Comment by Adam Rivera on May 21, 2012 at 3:04pm

@Geoffrey: I should not have used an ellipsis. Those two statements were not related. I did not mean that the application proved its legitimacy.

@Adam: It's amazing the difference a few dots make... :)
