Brain-Controlled Remote

A new brain-machine interface has been developed that allows users to operate electronic devices (like a TV remote) using brain power alone. The system scans the brain with near-infrared radiation to measure tiny changes in blood flow that occur with mental activity.

Optical fibers relay the signal to a remote control which can then be used to operate a television, air conditioner, or other electronic device.

The new system weighs just one kilogram (slightly over two pounds) compared with existing systems, which are the size of a refrigerator. As an aid for the physically disabled, it should be ready for commercial distribution in three to four years.
