@tink@w3c.social Interesting, but is this not EMG/EOG dressed up in BCI clothing?! It seems like a theme to me that these potentially useful assistive devices are (in my humble opinion) miss-marketed in this way. I admit i'm sceptical overall about significant assistive applications of BCI ('brainwaves' ) - and certainly how this is portrayed in the media (which feels technoAbleist to me).
