Mind-powered gear shifting

Shifting gears using mind power – it sounds like something from a science fiction film. But it's something Parlee Cycles have achieved here and now with their Toyota Prius Project concept bike. This incredible machine is fitted with a brain-computer interface (BCI) which allows the rider to shift gears simply by thinking about it, using a modified Shimano Di2 group.
The system uses EEG – electroencephalography – to record electrical activity at the scalp of the rider, who must wear a special headset. These signals are then processed by a computer on board the bicycle. They're compared to patterns stored in a database and if a match is found, the computer can trigger an actuator such as a gear shift.
