() Facebook is so yesterday. A neurophysiologist giving a TED talk unveiled a new spy hardware on her audience that read their emotions during her lecture without any of them ever having to type an emoticon. Big Brother has a Big Sister who promises that this is a good thing. Really?
“It is the end of the poker face. We broadcast our emotions. We will know more about each other than we ever have.”
That prediction/warning comes from Poppy Crum, which would be a great name for a singer. Although she’s in the music business, Poppy Crum is not fronting a band but is instead working behind the microphones and speakers as the chief scientist at Dolby Laboratories, the major developer of sound technologies for consumer electronics companies. However, Crum’s specialty is neurophysiology and in that capacity she’s been outfitting volunteers in electroencephalogram (EEG) caps, heart rate monitors and skin response sensors while watching them with thermal imaging cameras to record their biophysical and emotional responses while watching videos.
“The dynamics of our thermal signature give away changes in how hard our brains are working, how engaged or excited we might be in the conversation we are having, and even whether we’re reacting to an image of fire as if it were real. We can actually see people giving off heat on their cheeks just looking at a picture of flame.”
