Brain-control technology company BrainCo was a hit, with dozens of attendees lining up to try out their product, the Focus1. At last year's CES, BrainCo received a lot of attention from foreign media. This year, they launched an app for the classroom. Focus1 is currently the first product in the world to use EEG detection technology in the classroom. The system includes software systems used by school administrators and teachers, as well as headsets for students. With Focus1, school administrators can create a smarter and more focused classroom.
