What will be the interface in 2012?

In this video, Jeff Han and Phil Davidson demonstrate how a multi-touch driven computer screen will change the way we work and play. This looks like a perfect experience with PC -more natural and efficient. But is it really the way you would like to work for 10 hourse a day? After an hour your hands can become tired.

Remapping the Universe

Of course, you can change an orientation of the presented screen to horizontal but still I think the future is in the devices where a small move of your fingers, or even your thought, simulates movement presented in the video. Like a trackball - little effort and a pointer goes from left to right.

And what about Brain-to-PC interface launched by an Austrian firm?
