Has anyone used Muse for usability testing?


I’m interested in utilizing Muse’s EEG technology to get usability insights, like when users are frustrated, delighted, attentive, stressed, etc. Has anyone collected this kind of data before, or used Muse similarly to “read” and analyze emotions in response to tasks?

I guess this is kind of along the lines of neuromarketing, so if anyone has thoughts on using Muse for this purpose, would love to hear them.
