In a recent TED Talk, Tan Le of Emotive Systems demonstrates a wireless headset that can read your brainwaves thus allowing for control of electronic systems. Le highlights a few applications including the ability to control on-screen graphics, smart home features such as closing curtains, and controlling an electric wheelchair.
The headset is relatively simple compared to previous research designs that utilized hairnets completely covered with sensors. As Le describes in her video, the research behind the technology is non-trivial and calibration is necessary for each individual.
