The idea of anything recording your brainwaves may set off warning bells, but the Emotiv Insight wants to help you rather than hijacking your brain power. It's a wireless headset that records your brainwaves and translates them into data you can understand. It measures everything from attention and engagement, relaxation and stress levels to facial expressions. The idea is to give a picture of your cognitive health, and optimise brain fitness , without the need for a lab setting. All the data can be viewed on a smartphone or computer. It will be open to developers , meaning we may get exciting new applications for it.
