Thats one small Leak for the Leap

As you know, the devvvvs never sleep and constantly come up with implementations of random stuff, which you have to catch up with.

We have been accepted as one of the first who get a free development version of the Leap Motion device. The device is not yet available, but if your lucky and also got one, you can use it with vvvv right away.

Leap will ship another 10k dev devices in the next week, you might be lucky. apply here:http://developer.leapmotion.com

Otherwise this is just a public announcement that the Leap SDK found its way into our code base.

Great stuff TF

So many new things!!! :) Grat work!
Does the sdk have a way to get the ir camera video ?
will it ever be possible to use this device as a Kinect with Reconstructme ?

tonfilm 19/12/2012 - 20:01

they said, that the driver does not allow access to the raw image data. there is some processing on the device, which makes it useless. but many developers asked this in the leap forums. maybe they will open a channel. right now you only get tracking data of hand and fingers with position and direction vectors.

elektromeier 19/12/2012 - 23:22

and how is it in terms of accuracy & latency?
how many hands in can track the same time?

can u bring this thing to the node?

metrowave 20/12/2012 - 00:13

Sure, I'll bring it. It is shame though that thus far only tracking data is open.

extremely good... best i'v ever experienced, really.
i tried with woei up to 4 hands. it was getting a bit jerky then, but that could have been the lightning condition.

sure, we will have it at node13 in the hackspace...

they are saving this feature for late use ? mmm...

anyway this its a great tool for interactive installations that require high precision !.Does this work as the kinect sensor? like this video,,,


or its like 2 standar cameras ?

im traveling from Argentina just for Node13, so i will be happy to meet all of you and to see this on hackspace!. :D

metrowave 20/12/2012 - 21:01

The difference of this and Kinect is in accuracy really, and hand gesture is central obviously, as this video explains:


The Cobra sounds very promising but it's nowhere to be found and the company Canesta has been bought by Microsoft http://en.wikipedia.org/wiki/Canesta .

But I agree that Leap is delaying their product...

Finally got my dev device (and surely lots of you too). Could you update the Leap node to support the current SDK version, because it does not work right now unfortunately?

Thanks in advance and thanks for making that plugin available that fast! Would be great if at NODE the plugin would be working, because there will be at least a few leaps available for testing.

metrowave 01/02/2013 - 19:09

I finally received the Leap as well, but having problem with Display/Screen ID as it shows my screen ID as 0 and Leap is looking for screen 1, so nothing is happening. I'll have to try dual screen set-up later to see if I can resolve this issue. It could be different outputs from my graphic card Nvidia Quadro 4800 which is the problem. The monitor in my office in the university may not be the best, or even the graphic card configuration.

A bit disappointed that I had this problem straight from start, can't wait to get it working. I'll try it on the MAC SDK later to see if on Macbook pro it's different story (I think it will work there).

tonfilm 01/02/2013 - 21:23

alpha builds now come with Leap SDK 0.7.3.

metrowave 02/02/2013 - 02:14

Great Thanks again tonfilm, I solve the problem it had nothing to do with screen/monitors or graphic card. The problem was the USP port wasn't giving enough power to turn Leapmotion on. Switched the USB port to rear ones and it worked instantly. Also the latest alpha and Leapmotion patch/plugin works well although jumpy. But that is something that needs correcting through the SDK. For now at least it is possible to experiment.

herbst 10/03/2013 - 17:53

Just wanted to inform that there is a new SDK version (0.7.5) with basic gesture support. Would be great to see that plugin updated.
