Please, for the love of Jef Raskin and Henry Dreyfuss and Don Norman and all that is human factors, no. The film version of Minority Report was not a model for practical or usable interface design.

How about for presentations? You are already using your hand and talking naturally, why not incorporate that into your talk?

I wouldn't use it as a keyboard replacement, but for other tasks that naturally fit into this type of human input.

There's too much focus here on the assumption that this will be used as a full-time computing input device. I don't think anyone is realistically advocating banishment of all keyboard/mice to the netherworld. Let's be more creative than that. Think about using it as an alternate input in spaces that a physical keyboard/mouse isn't appropriate, and also 'short term computing'. Will this replace input on your workstati…

Ultimately no this will not replace the keyboard and mouse but these guys seem to think it will. Check out the headline on the about page: > Say goodbye to your mouse and keyboard.

To be fair, I remember seeing a mouse demoed in the mid eighties and the fellow at the demo explaining that you'd never need a keyboard again. He then proceeded to write a short sentence by using the mouse to click on letters on the screen.

I think that every new HID comes with a marketer promising to get rid of your keyboard.

As an embodied cognition guy, I disagree here pretty strongly. Gestures are a powerful form of communication - consider deaf signers, scuba divers, even in time sensitive operations like military and sports. Gestures likely have a deeper evolutionary history than spoken language too. They are intuitive. Babies mimic long before they speak or manipulate.

Yes for communication with humans, but for interacting with a computer? Gestures are imprecise, physically tiring and non-intuitive for the very precise and specific actions we have to do on a PC every day.

I wouldn't really say that it bothers me. I posted the link to the above discussion because I think if someone comes to the comment section they might be interested in it. But it certainly wouldn't hurt to do a quick HN search before posting a new submission.

> ... it certainly wouldn't hurt to do a quick > HN search before posting a new submission. Won't happen. I've been saying it literally for years, and I can tell you now, it won't happen. I implemented the first-phase of a semi-automated duplicate detector to help people find previous submissions, and I got hate mail for it. Some people are actively against duplicate detection.

Plus dupe detection is trivial to defeat. Basically, the current set-up works in favor of people gaming it.

That's an interesting perspective that I hadn't thought of before. The usual approach to a 3D gestural interface is the kind of thing that's shown in the video for Leap—writing in the air, using mimed actions in space to represent manipulation of objects on a 2D screen, et cetera. Gestures as an abstraction, like sign language or even the everyday hand gestures we use like flipping the bird, the "A-OK" sign, and such…

Upvoted both of you for civility :-)

The big question for me is whether gestures began as a proto-language. Consider mimicry and the use of tools in social learning. That's animal cognition too.

> Say goodbye to your mouse and keyboard.

This single line is enough to help me see through their flawed assumptions. The keyboard and mice aren't going away anytime soon, just because these guys have found a way to integrate gestures with computers. I personally hate the Applesque marketing promising users to 'Own the future'. Gesture technology has been here for long and I don't see it being the future by replacing the mouse and the keyboard. Think about developers like us...no developer would find it useful, because we need to code efficiently, which is and never will be possible with gesture technology.

So, from a developer's perspective, this is something intended to be too cool, but fails to understand the basic underlying principle of the purpose of a keyboard and a mouse. Maybe, this would appeal to ultra Hi-Fi executives who want to flaunt to the world a new way of using their Powerpoint slideshows, but not the common man/developer who owns an average computer (Something like a c2d).

I was honestly expecting this to have some features like the Kinect, which developers have hacked to use it as a motion-capture system, especially for use in creating Animated movies (which is awesome because a standard decent mo-cap setup will cost you atleast $5k). This gadget is unfortunately too basic and solves a very small problem that no one really cares about, IMO.

Those are based on static symbols and are not used for precise, realtime control of a stateful 2-D system.

I think this has great potential for use in conjunction with wearable computing such as Google Glass. I'm not sure how the current interface for Glass works, but I imagine it's based on voice input and possibly some buttons on the unit itself.

Imagine wearing a smaller Leap controller on your wrist - you would be able to use gestures to control the Glass and mostly likely interact much more intuitively with your surroundings as seen through Glass.
