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. i can blow up enemy squares in games, and use my mind as a television remote control. but the simplest demo actually had the greatest impact. you are asked to enter a pin numberjust by focusing on the buttons to click and the feeling of control is astonishing. wow. where i see it totally exploding with a combination of ar. so, in a few years from now, we will have ar glasses
