Kismet robot. Researcher Cynthia Breazeal interacting with Kismet, a robot that responds with facial expressions to her actions. Kismet has been developed for the study of action recognition and learning. Kismet has several 'moods', which it displays as expressions on its face. The researchers use movements as visual stimuli. Kismet responds like a baby. When there are no stimuli, it shows a sad expression. During play, as here, Kismet looks calm and happy. Too much stimulation causes it to become distressed. Breazeal works at the Artificial Intelligence Laboratory, at MIT (Massachusetts Institute of Technology), Cambridge, Massachusetts, USA. Work on Kismet started in 1998.
