Mind-reading technology lets you control tech with your brain — and it actually works

[2020.01.10, Fri 21:03] There's a growing category of companies focused on the "Brain-Computer Interface." These devices can record brain signals from sensors on the scalp and translate them into digital signals. "Your vision is in your brain, and we analyze your vision in your brain and we can know what you want to act upon and then we can modify that to basically create a command." Staring at a TV screen, I could activate a menu by focusing on a triangle in a corner of the screen. From there, focusing my eyes, I could change the channel, mute or pause video, just by focusing on a triangle next to each command. Another company focused on the brain-computer interface, BrainCo, has the FocusOne headband, with sensors on the forehead measuring the activity in your frontal cortex. "FocusOne is detecting the subtle electrical signals that your brain is producing," BrainCo President Max Newlon said. A light on the front of the headband turns red when your brain is intensely focused, yellow if you're in a relaxed state and blue if you're in a meditative state.
