This is all over the net today.
http://www.ted.com/talks/...ixthsense_technology.html

Is this something to get excited about?

Some interesting and cool demonstrations of what mouser pointed it is largely "old" technologies, but converged (supposedly) into a more cohesive and functional device. The thing is I don't see how many of the things demonstrated in the videos actually work, and until I see 3rd party demonstration of it (e.g. by an independent reviewer), I'm rather skeptical.

For example the "copying" of things from the real world on a piece of paper into your projection system, sure I can see that, just take an image and overlay it in your display. There is one problem with this, which is how do you separate background from the object you want to copy - in the example shown (a pie graph) it's a white background, so maybe that's a requirement. That would be rather limiting if so, but better than nothing. I can believe it working in the case shown.

What I don't trust as much is when he then takes that object and adjust the ratios of the graph! That is a much more difficult thing to accomplish, and I have my doubts it was done in any sort of dynamic way, rather than the more likely mocked-up or specially coded demo. Even if it is really working that way, it is surely with a very small set of use cases, and yet it is presented with the idea that it is showing this incredibly flexible tool; with the implication that you could interact with almost anything this way. In reality

In general the whole thing is a bit curious too, because he shows the helmet with the projector and camera early on, and then later all you see is a small thing around his neck. OK, there are micro projectors now, the size is not a problem. But what about all the incredibly odd angles that things would need to be projected on throughout the video? You always see the projected image, or him, never really both at once (except parts obviously, like his hand or arm). It's never really showing how the projector is positioned *as* it projects, and how it is aligning with the surface. Certainly there are corrective measures that can be taken on image output, but to believe they can be that extreme (the device around his neck was not fixed in place, so it could be at all sorts of odd angles), and done that quickly, is a bit of a stretch to my mind.

Interesting, but waiting for further proof of capabilities...

Edit: Re-watching the video, for the most part it looks like he puts objects down in range of where the projector *could* project, but the angles are still often odd. The use cases are limiting for this reason alone. And I imagine it might end up affecting your posture if the only way you could change the position of your display was to shift your body around. Wink

There is also another TED "talk" where his teacher or some other MIT person also "demos" the technology... but what's odd is that she claims to be wearing the device around her neck which, presumably, works (and costs only $350), yet you never see her turn it on or use it or actually *demonstrate* it. Everything in the "demo" is just the same clips from the original demo. I guess maybe this is TED US vs. TEDIndia, and that's why it is "presented" again, but it does seem odd that two presentations were made, neither one of which with any practical demonstration of the technology.

I just showed this to my wife and had to explain that it was more like selling a car than taking it for a test drive.

Yes Oshyan, it seemed very controlled and some of the bits obviously left a lot out (was that pie graph converted to spreadsheet + graph or just vector pie? or was it just interacting with previous data?)

I was amazed really that it touched on the things we talked about in that other thread about touch display. I loved using his hand to dial the phone!

For me, the ideas of getting the computer user out from behind a desk and freely interacting with it was very interesting (and made me feel like just another machine sitting in front of a machine at work  embarassed well, sort of anyway)

The gloves are old tech. It has being used for years in motion capture when you need more control of the motion of the hands.

A profesional glove would look like this: http://www.metamotion.com...re-gloves-Cybergloves.htm
If I remember correctly newer globes uses the bending of fiber optics to get the amount of bending that each sensor had. Resulting in movement that is not handicapped by the pulleys.

The rest is interesting but not really new, if you like anime, chances are you have seen the idea before.

Now if he actually made the stuff, then it would be something. I don't believe that buy listening to the sound a paper makes you would be able to know where the finger is. So the demonstration is just the simulation of an idea.

One idea, not mention here, but used at NASA is to motion capture the eyes of the person, so that you know what the person is looking at. Thus moving a cursor. BTW this was found by accident, while trying to do facial motion capture.

At the end, many of the technologies will be used mainstream, but many will not. Have anyone tried a 3d desktop? It seemed like a nice idea at first but is highly unpractical. Thus why hardly anyone uses them today. How about virtual reality. Well people found that they do not really want to totally immerse themselves into a limited machine world. (well, except people that play MMPORGs smiley ) Now the idea is to digital enhance reality. Only time will tell hoe good or bad is the idea.
