BCI System- Second Life

"A research team led by professor Jun'ichi Ushiba of the Keio University Biomedical Engineering Laboratory has developed a BCI system - which stands for brain-computer interface - that lets the user walk an avatar through the virtual world that is Second Life without using mouse, keyboard or any other controller but the power of thought."

I had no idea anyone was doing this. I think I'd need a choice though. I wouldn't mind moving my avatar with my brain signals for awhile so long as I could switch to some sort of body motion detection system. I'd enjoy walking in real life in front of a camera and having my avatar do the same.
