Science And Creativity From Studio 360

EEG — electroencephalography — is almost a century old, and it’s creeping out of the research lab and the neurologist’s office. Headsets embedded with electrodes to read electrical activity in the brain are commercially available, and designers are using that information for all sorts of purposes. On the one hand, experimental wheelchairs can now be guided by brainwaves; videogame companies, inevitably, are exploring game control without a joystick.   Exciting as that may be, Henry Holtzman, the Chief Knowledge Officer of MIT’s Media Lab, feels that EEG has a larger potential.
