Anime cat ear headbands have been around for a long time. But these, developed by Neurowear, can be controlled with your thoughts. At least, that's the bold claim that the company makes about the "Necomimi". Just concentrate to make them stand up.

Plausible.

Still plausible?
Yup. EEG is just picking up transcranial emminations from the brain. The brain generates a field which permeates through the cranium and the EEG is able to pick it up. But it quickly dissipates.
Newer techniques allow for the identification of classifiers that recognize patterns in complex field patterns. Soon et. al. used such a method to predict human decisions 7s prior to conscious awareness with a high success rate using functional Magnetic Resonance Imaging (fMRI). Results were published in a paper called Unconscious Determinants of Free Decisions in the Human Brain. I post a link to the video lecture that describes the method of classification.
There may be some way for them to pick up transcranial field emminations and classify it. It's not completely fantastic. Keep in mind that plausible, true and false are three different judgements.

Sure. But you're not really believing they're doing all that with their headband right. Or are you?
No, I'm just saying it is plausible. I have a lot of doubts about it.
Sure: maybe it is "theoretically" possible. (I'm not even sure of that, but let's assume for the sake of argument.)
But there is a BIG difference between something that is "theoretically" possible and something that is "plausible".
Plausible means (imo) that it is realistic under the circumstances. What they propose in this article in my opinion is not plausible under the circumstances.
