Researchers from the Biomedical Engineering Laboratory at Keio University in Japan have developed a brain-computer interface that enables users to control the movements of Second Life avatars without moving a muscle.
The device consists of a headset containing electrodes which monitor electrical activity in the motor cortex, the region of the brain involved in planning, executing and controlling movements.
All a user has to do to control his/her avatar is imagine performing various movements. The activity monitored by the headpiece is read and plotted by an electroencephalogram, which relays it to a computer running a brain wave analysis algorithm that interprets the imagined movements. A keyboard emulator then translates the data into signals which can be used to control the movements of the user’s on-screen avatar in real-time.
Below is a film clip of the device in use.
