As a prerequisite for this idea, checkout
2ce.com. And think about the scene in Minority Report where he's digging through the case files and his interface is this gigantic screen and his commands are based on hand movements.
It seems that we've been using this interface of monitor+keyboard+mouse for a very long time now. And all GUI's are designed based on this old, uncomfortable, and possibly deficient interface. Isn't it about time that a whole new interface be designed from ground up? Within a few years, virtual screens projected on eye goggles will probably be pretty cheap and have very high resolutions. Or, maybe flat panel technology will jump leaps and bounds and we can have 60 inch screens for our computers. The mouse+keyboard system will surely seem very inadequate for such a technology. The idea is to come up with something more 3-D in nature. The mouse is very 2-D. Think in terms of utilizing BOTH hands to do mouse-type operations. You hardly ever use the mouse and keyboard simultaneously. So why not attach some gyroscopic sleaves on your fingers which are automatically active when the keyboard is NOT in use (the details of this system have not been worked out but it should be fairly trivial to switch between mouse and keyboard modes)?
Look at the 2ce site and you'll understand how this could come in handy!
Obviously, along with the hardware for this new interface should come a new GUI. Something that can take advantage of the human brains multithreading abilities.
