"Disney’s next-gen “realistic gaze” animatronic figure uses a chest-mounted sensor to identify people so the robot can turn to face and engage with them. A series of smaller motions allow the highly animated and articulated robot to create the illusion of life. The animatronic’s head rises and falls subtly to simulate breathing. Quick, darting eye movements by the animatronic create the illusion of examining a person’s entire face. The animatronic can momentarily shift its gaze in reaction to a sudden sound in the distance before refocusing on a person’s face."
