With new products made available on display at CES 2020 in Las Vegas, tech devices that use brain waves to improve sleep, anxiety, and concentration -- and even control prosthetic hands -- may finally be made effective.
Companies are focusing on the "Brain-Computer Interface" with devices that can record brain signals from sensors on the scalp (or even devices implanted within the brain) and translate them into digital signals. They allow us to connect our minds to computers for some limited purposes, and big tech companies including Facebook and many startups want to make this technology commonplace.
