- I can't say whether it applies to this particular setup,
- but some of the simpler so-called EEG sensing setups have turned out
- to be reading head muscle movements instead. A few years ago some
- organization had tested so-called brainwave measuring machines for
- meditation enhancement and discovered this fact. Turned out to be
- detecting eye or jaw muscle contractions instead.
-
- Then again, an electrode cap may be a more cost effective eye movement
- tracker than some of the alternatives.
