Control a model train using only your brain

It’s called optical topography, and it’s a neuro-imaging technique that uses near-infrared light to map blood concentration in the brain, the system recognizes changes in brain blood flow associated with mental activity and translate those changes into voltage signals for controlling external devices.
In experiments done by Hitachi, test subjects were able to activate the power switch of a model train by performing mental arithmetic and reciting items from memory.
Eventually, brain-machine interface technology may help paralyzed patients become independent by empowering them to carry out actions with their minds. Hitachi hopes to make this technology commercially available within 5 years. Slick.

[…] Being able to control a model train with your brain is cool. But using your mind to control a robot is much cooler. As you can see, the person is wearing a cap with electrodes that sense the signals and reflect a person’s thoughts. This lets you command a humanoid robot, making it move to specific locations and pick up things. Watch the video… […]

[…] So you can control a robot with your mind, and drive a train using your brain, but what about your thoughts controlling a video game? Meet Emotiv’s ‘Project Epoc’ - It’s basically a helmet with electrodes to monitor electromagnetic signals coming from your brain. Then, it interprets those signals to control the video game you’re playing. […]
