Life has become very easy and comfortable with the use of remote control. Everything operates with a click of a button. Imagine if we wouldn’t even have to lift our finger and yet could control devices with our brain activities. Hitachi has made that also possible. A new technology using brain interface allows you to control electronic devices simply by reading brain activity. A cap connects by optical fibres to a mapping device, which connects to a toy train set via a control computer and motor. Just by doing simple calculations or sing a song you can run a train. When you stop the calculations, the train stops, too. The technology is called optical topography, which sends a small amount of infrared light through the brain's surface to map out changes in blood flow.

The technology could one day replace remote controls and keyboards and perhaps help disabled people operate electric wheelchairs, beds or artificial limbs.
