My son got one of the Emotiv headsets as a college graduation present. It’s pretty amazing tech, early-adopter gear, for sure, but with tons of potential. He’s already coming up with ideas for game designs and art installations controlled by it (he has a degree in game design). In this video, Robert Oschler, of Robots Rule, uses his Emorate software to demonstrate the power of “affective computing,” using computers to detect and react to human emotions. Here he uses various emotional responses to index, bookmark, and navigate a video using the Emotiv headset and Emorate.
