The place I work for recently received a Muse, and I am trying to get some signals out of it, to use on some externals applications.
The first sessions I performed had the intention of learning about the device.
I have experience with OpenBCI and OpenEEG (built version by Olymex).
And the test I am using to “benchmark” the device is a simple Alpha testin:
1- Open my eyes and talk for 5 seconds;
2- Close my eyes for 5 seconds;
3- Wait 10 seconds and repeat twice;
Using both the aforementioned devices I could get peaks on the alpha spectrum, and really identifiable ones. But using muse (MuseLab, running default command muse-io --device NAME), the waves for Absolute alpha for each channel seem to vary randomly, rather than following a pattern.
I already tried to clean my forehead with several products (the first idea was that it was caused by interference), and turning on and off the device. As well as trying another PC. Tried to perform the tests on a unplugged laptop (even though the DC offset from the wall plug won’t affect muse), and to no avail. Seems like the alpha Absolute is varying randomly.
I have already did some research, and found nothing like my question. =)
So, I may ask you:
1- Is this a problem with my device?
2- Is this the normal behavior of the waves?
3- Should I use conductive paste/gel when wearing Muse?
4- The approach to test the device responsiveness is wrong?
What else should I try?
Thank you in advance for your attention.
