New research is giving computers the ability to recognise, express, and in some cases "have" emotions. The emphasis is on emotional intelligence, which can be more important than traditional mathematical and verbal skills when it comes to interacting successfully with people. This talk will explain recent efforts to enable computers to recognize human expressions of emotion, and to respond appropriately. As shoes, hats, jewellery, spectacles, and other accessories become the sites of a new variety of computing, we obtain a fundamentally different interface than the traditional keyboard and mouse. I will show examples of new "affective wearable computers", including spectacles that communicate expressions such as confusion or interest, and a wearable "StartleCam", a first step towards a personal camera that automatically notices what gets your attention.
