Will Your Next Touchscreen Be Touchless?

forgot_my_username writes "The MIT Media Lab is developing a motion screen computer. It looks back at you. It measures light and gestures, and uses those to control the interface. 'Imagine every pixel on your LCD screen emitting light could also be receiving light,' said Ramesh Rakar, an Associate Professor at the Media Lab. They even mention the health benefits of not touching displays."

I prefer the keyboard. It's still the most effective input method and the fastest way to manage your computer and smartphone (provided you learned the hotkeys and commands).

Ooh...

Forget this "touchless touchscreen" nonsense. Combine this with the various clever stuff being done in lenseless digital imaging, and we will finally achieve the dream... A Telescreen in every house.

Look for it in the next dubiously compatible revision of HDMI: "Secure audience reporting protocol" an HDMI spec extension allowing your TV to report the number and approximate demographics of viewers to your Blu-ray device or cable STB. Pay-per view programs can now control the number of viewers, V-chip 2 can now detect child-size viewers and automatically halt display of R-rated content(sorry midgets, its for the good of the children)! Neilson will be completely obsolete!

What could possibly go wrong?

The bandwith of 10 fingers is a lot higher than a mouse with just one pointer and a few buttons. You can potentially transmit a lot more instructions in a lot less time using your hands, if only we figured out a proper way to make it work.

Yes, but it already exists: it's called a keyboard.

Claiming buttons are good does not publish any papers; everyone knows this. If you claim some kind of button substitute is good, you can publish two papers. One making the claim and then another comparing it with buttons in a user study and showing that, actually, buttons are better. If you're really clever, you can then publish a third paper on the methodology for evaluating button substitutes, and a fourth paper on potential problems with future button replacements. Guess which route academics prefer.
