The svelte Emotiv headset uses an array of sixteen EEG sensors to detect electrical impulses in the scalp. These signals are then interpreted by a suite of tools, each with its own range of applications.
The “Expressiv” application identifies and interprets facial expressions; one of Wixson’s associates demonstrated winking, blinking, and an unnerving grin, each of which was replicated on a rough facial model. Another application, called “Affectiv”, recognizes emotional states.
The most substantial and interesting application is the most active one, “Cognitiv”, which “classifies conscious active intent”. That is to say, it interprets what the wearer wants to do, allowing a player to execute specific commands and actions through thought alone.
