Hi would anyone be using a technique like this to measure attention /
concentration in a VE?

>(WO9942032A) Novelty - The frontal lobe sensor unit of a headband (10) is
>positioned on the user's forehead (64) and ear sensor units are positioned
>against the upper portions of the ears (66). Signals from the sensors are
>amplified, digitized and filtered by an interface unit (30) to provide a
>processed signal between 0-40 hertz, which is passed to a brain-wave
>analysis program running on a computer separate from a main computer (90).
>The signal is processed to produce an attention indicator signal, which
>may be averaged over a desired time interval.
>Detailed Description - An independent claim is included for a method of
