and the next generation is consciousness of mind. we have achieved far greater than any technology from the previous generation. much of the brain computer research has traditionally been to help people with restricted mobility and the breakthroughs prove that this could be a game changer. but now there are a whole host of headgear—based neurotech companies springing up in the consumer space and one of those is a french start—up nextmind, who have created a headset that lets you control computer interfaces just by thinking about it. so really simply, this is an eeg sensor that sits at the back of your head. it measures the electrical activity in the visual cortex and detects what you're looking at. the visual cortex is the part of the brain that processes what we see. when you're looking at specific points on the screen, the sensor detects that increase in visual concentration and communicates to a button you want to push. a few demos show you what's possible.
