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.

Shouldn't this be a problem with whiteboards/blackboards as well?

Wow.. I would love to develop for this.

I dropped out of state U. after my 3rd year (math major), but that was years ago. At my current start-up, I have recently been forced to learn much more than I was expecting to about probabilistic graphical models and curve similarity measures (gladly though; always been interested in pattern recognition).

Anyone with a vision for this, consider dropping me a line. I might be able to help.

Let's have a constructive comment thread. Instead conveying love or hate for it, how about listing the cases it's good and bad for. good * Fruit Ninja - made for single finger input, short gameplay * Pinching and zooming maps - good because it's usually a short activity * CAD camera interactions - good for periodic strange rotation needs or showing a client that doesn't understand the normal movement hotkeys * Period…

Very very inconvenient. Writing on air is completely different and considerably more tricky that writing on paper. Physically more demanding too. It's one of those things that sound nice in theory, but not really practical.

If you're an interface designer (I am), you should pre-order this thing. This will be a standard form of interaction in a couple of years and you should jump on it early and start figuring out the kinks. Too cool.

It really won't. Have you any idea how tiring waving your arms around like that would be all day? There are so many use cases where it doesn't even work that would require a complete rethink of how anything is presented on in internet. For example how about the HN comments where it's pasted as code and it scrolls horizontally. Target that and scroll it with that system. As soon as you have a single use case where a m…

Agree that it can't provide the precision we need for arbitrary complex actions.

Disagree about the physiological concern. Provided your elbows are resting on the table, it would be easy to get used to. Humans would adapt and it would be healthier than our current much talked about static postures.

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?

You're right. I just tried it (not with the leap hardware) - the inability to "lift up" off the paper without leaving the sensor zone is weird. No haptic feedback when you're on the "paper" and not.

Earlier quoted context omitted.

Kinect is using stereo-vision using 2 cameras...I don't think they have the same technology here

Yeah, no. Kinect uses an IR emitter with an IR-based depth camera, there's nothing stereo about it. A regular RGB camera adds color, but that is all.

Not to nitpick, but there is a stereo aspect to it. The IR projector is offset laterally from the IR camera, and this is critical to evaluating the depth, because the disparity of the IR dots is more extreme the greater the distance between the emitter and the camera.

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 location) then I'd love this.
