Computer User Interface of the Future?

Ever since Xerox showed off the first mouse-driven interface to a computer decades ago, scientists and researchers have continually worked towards creating the perfect human-computer interface.  The mouse and keyboard have seen steady improvements over the years, we've seen the addition of eye and head-tracking controllers, tablet/pen interfaces etc.  The problem however is they're all limited by what we already have.  They're just different ways to emulate the mouse.  To this day, manipulation of objects on a computer screen had been limited to two points of movement/control.  One researcher at NYU however is making some very serious progress on an entirely new way to interact with your PC... with your hands.

And when I say hands, I don't mean like you use them now.  Not even like you use them on a conventional touch-screen when you order an MTO at Sheetz.  Jeff Han has come up with a way to use your computer in one of the most natural ways imaginable, using as many fingers, or points of pressure as you like, you can manipulate icons, photos, windows, anything as if you were grabbing it with your hand in the 3D world.  He recently gave a keynote speech/demo of what he has accomplished to a conference in February of this year.  The technology is called Multi Touch Sensing. 

Check out the video... It's really amazing!  It's a completely intuitive, interface-less way of interacting with a computer.  Once this makes it out of the lab and into the real world, we may see the concept of computer use completely change!
