I work with EEG quite a bit, and after checking out the pictures, here is my take on it . The unit attaches to O1, O2, T3, T4, T5, T6, C3, C4, F3, F4,
PF1, PF2, LOC, ROC and two locations that we do not normally monitor between F3-T3, and F4-T4. Here is a Chart showing the 10/20 electrode positions
that you can check against the photograph:

Folks who are worried about this reading their minds have nothing to fear, we are a long way from being able to do that yet as each persons brain is
wired differently. We cannot tell when a neuron fires what memory or thought that neuron is related to. However there are certain functions that are
wired the same way in everyone, and certain patterns to normal brains waves, and those we can read. Some of the things we can detect are: Various
brain disorders (Coma, Seizures, Brain Death (obviously
)…etc), Eyes open, Eyes closed, Eye movements, Drowsiness, Sleep, Sleep stages, Pain,
Muscle tension, Some movement, Substance abuse, Some changes in body temperature (Hot flashes, or Sweating), When someone hears a loud noise, and a
few other minor things that are eluding me ATM. Most of this is interpreted by the Shape, Amplitude, and Frequency of the Brian Waves, with the
exception of Eye Movements. We can in no way read what a person is thinking or dreaming at this time.
I suspect that this machine works mainly on the ROC/LOC eye movements, and is sort of like a joystick that follows eye movement on the screen. It
might even be able to read the signal that you would like to push a button or pull a trigger before you physically do it. I suspect that it detects
most of the facial movements and emotions through reading muscle tone. Obviously a person that is upset or under stress is going to have a lot more
muscle show up in their EEG then someone who is relaxed or dosing off.
It’s a neat novelty, but I doubt it’s going to function well for gaming, as
nataylor quite correctly stated. At present, we have to prep
people vigorously for a clinical EEG, then we have to monitor and interpret what is coming from that EEG, constantly fixing and adjusting things
during each test. I doubt that folks using this unit are going to get a good signal due to questionable placement, poor impedances, EMF interference,
and variations in amplitude. Also if the unit does not have the Analog to Digital converter as hardware, as well as whatever is interpreting the
signal, then you are looking at a lot of overhead in software, chewing up system resources, to be running besides a game.
