Reasearchers at the MIT Media Lab are developing a wearable device that would read subtle movements of eyebrows, lips and other features, synthesize the information and tell the reader about the subject's emotional disposition. The device, indcluding a tiny camera, could be concealed in eyeglasses or a ballcap.
There are applications for people with autism, the dating scene and job interviews. You could immediately tell how your answers were being received by interviewers and adjust.
But the ballcap might tip them off. Check out the Boston Globe article.
