This seems a lot like a simple application of Leap Motion

maybe just providing 2d data is much easier to digest for apps.

Will wait for a review before putting money down - there are a lot of unused Leap Motion devices out there, I'm going to be cautious in future.

Absolutely, although I was surprised it was available at only $75! Looking forward to see some reviews especially for Linux.

For somebody who hasn't messed with a Leap, what was the problem with them?

I didn't try it at length, but it just wasn't as good as it sounded - not as accurate and the API was very difficult to work with.

I remember seeing a significant software update a couple of months ago, which was supposed to be a big upgrade to hand tracking. Have you tried it after that?

No, I've long since given up on it.

Man, screw using that for multitouch. Going to use it as a depth camera. Been looking for a kinect-like device that I can mount on a quadcopter.

I love how most of the PC's in this video are macs, but they are all running windows.

So presumably they have multitouch trackpads with no good drivers available.

I want this but I also wanted the leap motion and got burnt bad. This does seem objectively more useful though. When old mate turns the device towards the projector screen and used it as a touch screen was awesome.

What problem does this solve again? In the video you see a man doing some complicated hand gesture to put his laptop to sleep. I normally just close the lid of mine.

hand waving is tiring. this isnt multitouch.
