I'm calling fake or very optimistic to say the least.

The promo video doesn't show a physical device, the price point seems ridiculously low especially for a resolution of 0.01mm. And also there is this http://bit.ly/KOqDi2 the physical hand and the point cloud don't match. It's like someone is moving their hand(s) fast to mimic the movement of the visualization.

I'd love to integrate it with my KType application ( http://ktype.net ) or build a new software that converts hand gestures / ASL to speech. I think it's totally doable and would be a lot of fun technically too. What do you think?

Well, off the top of my head I don't see a straightforward way to integrate with KType (nice work btw!). Just because there would be so many possibilities for mapping hand gestures to the KType actions/commands. On the other hand, converting sign language to text/speech seems like it should be quite straightforward. Not knowing anything about sign language, I'm assuming signs map (more or less) one-to-one with words.…

So sign language isn't really one-to-one, but that is something that I really want to work with, so I look forward to getting a unit. I think this system has a lot of potential as a learning tool! Awesome job guys!

There's no perceptible latency in its response to gestures -- I'm very impressed assuming it's not a rigged demo. (In videos I've seen of the Kinect the software responds to a gesture only after a noticeable fraction of a second.)

It doesn't look like a rigged demo http://www.cbsnews.com/video/watch/?id=7409264n

I'm happy that the team took their passion to execute one something so effectively. But not all ideas are good. It violates Fitt's law by placing all user interaction within a vertical band next to your computer. This is very uncomfortable and decreases the usefulness for most applications (because missing the interaction band is likely). If these were wireless gloves that I could more easily (with my arms in any loc…

Putting on gloves is kind of goofy and severely limits the applications.

Also, this is the first iteration of the tech. The same tech can be used to cover a football field and more.

I’d love to get one of these and play with it. Will the SDK and spec for talking to it be freely available after the initial batch of preorders and free dev kits? As a counterexample, Emoviv gave a TED talk a while ago showing off a headset that lets you control your computer with your mind. When you visit their website you discover that you can only develop with a $500 “developer edition” headset that comes with a s…

Dev Kits ship for free to 20,000 developers in 1-3 months. Pre-orders are for consumers at $70 and ship this winter. The idea is to give all the hackers maximum access to create awesome apps and then deliver a healthy shiny ecosystem to the consumer. Also, we'd like to see a larger shift towards people creating things, so encouraging early adopters to get aboard the coding train is a positive trend. It's a huge new i…

So this will run approved software only as well?

Well, that's a big turnoff for a dev. Why instead of maximizing the short term profit you concentrate on the long-term and make this system open with certain limitations to assure your business?

I'm sad the word 'robot' hasn't appeared in this thread yet. Let's correct that. Visual slam is great for medium distances, but pointclouds aren't really that dense and are slow to update. Also the lidar to make the point clouds is stupid expensive. Add one of these guys onto your robot and you've got a really cool set of 'wiskers.' Short range, highly sensitive, super fast update. I'd love to put several of these on…

I work on adaptive mobile robots as part of my research, and I'd be very interested to see how the LEAP compares to the Kinect in this area. I submitted a developer kit request, so maybe I'll get to find out.

Also, from the Ars Technica post on LEAP:

"The company says the breakthrough in resolution comes not from the hardware, which consists of relatively standard parts, but from what CTO David Holz calls 'a number of major algorithmic and mathematical problems that had not been solved or were considered unsolvable.'"

I'm conflicted by that statement. As a current academic, I hope they publish these supposed breakthroughs, as hiding them behind trade secrets makes me sad. As an entrepreneurial-minded person, however, I understand the desire for competitive advantage.

as a side note. Consider how many positions you can put your fingers into. Now both hands? Now imagine if each position was mapped to a different shortcut... How many unique positions could you map? (compare to keyboard).

Imagine surgeons who can't touch a surface with his/her hands due to hygiene concerns using it to manipulate various images/scans of the patient on the table in front of him/her.

Well yes. If multiple solutions gain traction, it just proves that there is a market for this kind of thing. It's not about being first, it's about executing well. If Leap is more accurate for tracking movement, it could prove more suitable than the kinect.

Not to be cynical, but this reminds me a little of Alan Kay's comment: """ By the way, Sketchpad was the first system where it was discovered that the light pen was a very bad input device. The blood runs out of your hand in about 20 seconds, and leaves it numb. And in spite of that it’s been re-invented at least 90 times in the last 25 years.

Painters are able to operate a brush for full working days in the studio without the elbow support that a desk supplies here. It seems if the benefit is great enough people can work up the supporting muscles through repetition.
