They need to make the glass interface have a changeable display. A great piece of tech, but it is stuck on using an outdated concept, the keyboard and mouse. It does have the potential to get us closer to the future I have been dreaming of. Star Trek is not that far off afterall. 

A while ago I got a really cheap replacement keyboard, because my other one committed suicide after years of me using it to abuse grammar and spelling. It worked just fine, but after a while, the keys stopped springing back after typing. They still worked quite well, but when typing, I just couldn't feel as if I was pressing the keys. That lead to even more typing horrors. When I got a new keyboard, with keys that actually spring back, and travel a good distance until contact, I was a lot more comfortable. That's why I just can't fathom keyboards with no feedback such as these and the IR projected one.

It looks cool, and from a tech viewpoint it's awesome, but unless they add force feedback to it, I can't picture myself using something like this for work. 

Hopefully that picture is slightly inaccurate as otherwise there could be issues with key combinations where keys are above each other such as ctrl + escape or shift + tab.  Perhaps the amount of reflection there is only a small percentage of the total light.

I could also see potential issues with people resting their fingers on the tops of keys while thinking and I know I do that a lot with the spacebar.

Well ... if you're into all the high tech gizmos, which I am, when I can that is, you'll want to jump all over stuff like this just for the novelty. Too bad it isn't in production yet. Aside from the issues Neil pointed out I could see me owning a set. And as for ST .... this is far beyond that I think.

Typing requires tactile feedback, not to mention the ability to find and rest your fingers on the 'home position' without visual input.  The 'mouse', on the other hand, is a simply a trackpad by other means - would sure look cool on your desk, though.

Just like touchpads, tablets and touch screen PC's...one more thing to clean fingerprints off of.

Not for use while eating BBQ ribs, pizza, chocolate, jelly donuts, potato chips, etc. How would anyone here get any work done?

*Note to self: Buy stock in paper towels and glass cleaners.

Accurately reproduced, Neil. As for the rest, you'd have to ask the dev, I suppose.

@ Daiwa: Odd, but I was thinking the same thing. I suppose a coating like the iPad/iPhone has might do, but I do need the "springy" feeling as well.

I just love technologie, first there was the IBM folowed by cherry then there was usb keyboards those got replaced by wireless normal keys by back lid keyboards or random colored glowing keyboards - then there was the concept of laser projected virtual keyboards, The famous Optimus Keyboard with LED display keys- now this - i hope i will live long enough to still witness a ( real ) Holographic Keyboard.

Mind-meld keyboard is the ultimate answer.

tis' entertaining

what they all said...

I have to move the mouse Tried a track mouse before took for ever to get anything done, and kept wanting to move the mouse...

As far as tactile feedback goes, well it's not impossible to have the keyboard vibrate slightly when you touch a key, emulating the sensation of depressing a key.  This is used to good effect on touchscreen phones.  Granted, it's not perfect, but I would be really happy to have a keyboard that doesn't trap food crumbs and dust over time.

I'd think it would be a long-term ergonomic nightmare - constantly tapping on a solid object, even after you learn to stop "pressing" it.  Plus holding your fingers up constantly trying to avoid stray strokes.

And how. The keyboard's not an outdated concept until someone comes up with a better way to lay down text far faster than you could speak it,  without resorting to regressive ergonomics like thumbing all your text.

Those things are pretty, and look fairly easy to keep gunk-free, but they won't be a decent keyboard analog until they get some texture. Better yet, some plastic texture--something you could flex around a bit until it was a really nice fit for the size of your hands and your typical typing posture.

And (so far) keyboards are flat or a little concave - a convex typing surface would be very awkward.
