Brain computer interfaces (BCIs) enable people to control things by thought and nerve signals: they are emerging from the medical research arena. The technology of BCIs is becoming less invasive, sleeker and more powerful, with a growing number of applications from health care to gaming, smart homes to typing, medical research to market research. While not yet a mass market by any means, the potential for interacting with our surroundings in radically new ways is arriving.
