i'm dubious these things can accurately interpret anything more than face muscle tensions, eye-movement if that. which are common noise sources in EEG recordin

  You can eliminate noise/artifact like that by subtracting it from a reference point.

    but they don't seem to be doing that since "expressive" is one of the detection aspects they mention.

      I think that's just "eyebrows went up, smiling muscles contracted, blinked", etc. for the look-my-emoticon-changed marketing effect. They also claim there's a gyroscope in the device. The more advanced EEG tech is quite real. It's a stretch to say that it's interacting with your "thoughts" ... making something like PacMan move forward/backward is a similar sensation to when you first figured out how to wiggle your nose (the mental exercise, not the muscle movement).
