Personal Computer as Mind Reader

Microsoft researchers believe they may be able to improve the computing experience by giving the machine on your desk a general sense for what's happening inside your head.

The project builds on established methods of using sensors to detect electrical impulses from the brain and assess a person's cognitive state. Such techniques can determine, for example, whether someone's mind is relaxed, crunching numbers or imagining objects at any particular moment.

One test the researchers have run is with Microsoft's blockbuster "Halo" video game. With at least 95 percent reliability, they have been able to use the technique to determine whether the person is watching the game, playing casually or fighting an all-out battle against an enemy.

Don't know whether to be excited in the whole brain/computer intereaction front, or to be concerned about Microsoft getting access to what is going on in my head.
