Further clarification: when doing conventional EEG, the signal quality is so fragile that even blinking can produce recording artifact.
Also, there's the whole "put a shower cap with conductive gel" things that makes it very impractical for every day use.
- dmicah 3y agoThere are 'dry' EEG electrodes which don't require conductive gel, and algorithms to remove the electrical effect of eye-blinks (ICA, etc.)
- ramblenode 3y agoYou don't need a full EEG to do what the parent mentions. 3 electrodes around each eye (EOG) + ground is all that is needed. Even cheap commercial electrodes will work for this. Blinks can be filtered online with PCA-like techniques.
