Has any company done anything interesting with dry electrode EEGs? Most of the ones I've found use hacks like sensing head orientation or muscle twitches rather than brain signals. Dry electrodes seem to be useful for sensing "calm"/"focus" states but can't get any real data out of them. The most interesting one I've seen is NextMind which uses flickering visual stimuli that is picked up by the brain sensor, but this is a more cumbersome version of eye tracking. https://www.youtube.com/@perrikaryal/videos https://www.youtube.com/@perrikaryal/videos has some interesting EEGs based game control demos but it's clickbait since most of the inputs come from head tracking with a single bit (i.e, button down/up) of input from the EEG. And that can be done much better with a blink detector.
