Frankly, I could give a few of these out as Christmas presents.
MIT Media Lab researchers are building a device to help autistic people
determine if they’re boring or annoying the person they’re talking to. The
"emotional social intelligence prosthetic device" is a camera that clips on
eyeglasses and feeds images to a small computer that uses image recognition
software to characterize emotions. If the listener doesn’t seem to be engaged,
the device vibrates to alert the wearer.
