Your idea is that because people aren't walking around wearing these (https://www.researchgate.net/profile/Daniel-Lacko/publication/317304476/figure/fig3/AS:614363463426059@1523487072322/EEG-cap-with-gel-based-electrodes-inserted-Photo-by-Chris-Hope-made-available-by-Tim.png https://www.researchgate.net/profile/Daniel-Lacko/publicatio...) that the concept is flawed, rather than needing to be in a different form factor?
