What is the general strategy behind determining whether a blink has occurred? Is the algorithm open source or considered intellectual property of Muse?
Put generally, we use certain machine learning techniques to construct classifiers for blinks, based on data collected with and without blinks. I think that’s about as specific as I can get.
If you’re interested in getting more into the topic as a whole, though, there is a ton of literature out there on artifact detection and extraction for EEG signals. You should be able to access most of it through Google Scholar, or if you’re associated with a university in some capacity, through your school.
