I found this interesting thing that is currently being demonstrated at the GDC:

It reads your brainwaves to manipulate objects in a virtual world. It can also read your emotions. Apparently it works best with kids and people with good imaginations.

I always thought the next stage in gaming is something in these lines..If it gets even more advanced and does every action based on what you think...like even walking ahead or changing guns in game,then its going to be some really great fun..no need to even use hands..just look and play ona widescreen..wow !
