EOG saccade detector
We'd like to build or buy a light-weight, portable EOG system that
subjects can wear while walking. The goal is to quickly (in less than
5 ms) detect saccade onset, rather than measure precise eye
position.
More fundamentally, we're looking for basic EOG know-how. What kind of
electrodes and amplifiers should we use? Where do we put the
electrodes? Should we filter? Do we need to buy expensive and heavy
bio-amplifiers, or is there anything cheap and light-weight out there?
Does anyone have any experience with the OpenEEG designs
(http://openeeg.sourceforge.net/doc/modeeg/modeeg.html,
http://www.olimex.com/gadgets/index.html)?
Commercial devices that we have tested all do data logging with
considerable delays before data transfer.
We promise to post a digest of all EOG wisdom!
