Dr. Ramses Alcaide is explaining the electroencephalography (EEG) technology that his company Neurable uses to track activity with its brain-computer interface (BCI). Alcaide is the CEO and co-founder, and notes that a huge problem with EEG sensors is that they are often affixed to bulky, awkward-looking headsets -- not exactly something you want to wear out in public. And to him, that's why the technology hasn't yet "created the type of impact that they could [on] the world." Sure, we've seen a variety of headbands over the last decade, but those add an additional device to your bag. Alcaide argues there's a better way to use EEG tech that's even less intrusive.
