Professor Jun'ichi Ushiba of the Keio University Biomedical Engineering Laboratory has designed a
brain-computer interface or BCI to allow players of
Second Life to interface with the game and control and avatar with out touching a keyboard & using only the players thought!

While recent developments in brain-computer interface (BCI) technology have given humans the power to mentally control computers, nobody has used the technology in conjunction with the Second Life online virtual world — until now.
A research team led by professor Jun’ichi Ushiba of the Keio University Biomedical Engineering Laboratory has developed a BCI system that lets the user walk an avatar through the streets of Second Life while relying solely on the power of thought. To control the avatar on screen, the user simply thinks about moving various body parts — the avatar walks forward when the user thinks about moving his/her own feet, and it turns right and left when the user imagines moving his/her right and left arms.
The system consists of a headpiece equipped with electrodes that monitor activity in three areas of the motor cortex (the region of the brain involved in controlling the movement of the arms and legs). An EEG machine reads and graphs the data and relays it to the BCI, where a brain wave analysis algorithm interprets the user’s imagined movements. A keyboard emulator then converts this data into a signal and relays it to Second Life, causing the on-screen avatar to move. In this way, the user can exercise real-time control over the avatar in the 3D virtual world without moving a muscle.
Future plans are to improve the BCI so that users can make Second Life avatars perform more complex movements and gestures. The researchers hope the mind-controlled avatar, which was created through a joint medical engineering project involving Keio’s Department of Rehabilitation Medicine and the Tsukigase Rehabilitation Center, will one day help people with serious physical impairments communicate and do business in Second Life.

Personally I'm really not a big fan of
Second Life, but this is really cool! Maybe they will be able to do this for First Person Shooters too! zomg!
