My mistake. EEG.

https://www.apneaboard.com/forums/ May be worth posting over there too. 112k members and many interested in logging their cpap data with OSCAR. Trying whatever they can to improve sleep.

Some of my college friends created a skullcap wheelchair controller application using only the brain so the options are very open. Good luck.

Wearing a headband along with CPAP would be a challenge, though we are having a few people that want to try it. I'll keep that in mind in the future.

Thanks
