CONCEPT
Emotion as Architecture
Cynthia Breazeal’s principle that emotional displays in a genuine social agent are not decorations layered over intelligence but a regulatory control system that governs the agent’s behavior and shapes its interactions—the distinction that separates authentic affective architecture from the performance of affect for engagement.
Emotion as architecture is the concept that most directly distinguishes
Cynthia Breazeal’s approach to social robotics from the affective computing that came after it. In Kismet—the expressive robot head she built at the MIT Media Lab in the late 1990s—the robot’s displays of contentment, interest, distress, and fatigue were not animations triggered to seem lifelike. They were the visible surface of an internal regulatory system that governed the robot’s behavior and its relationship to the person in front of it. When its drive for social contact went unmet, the resulting internal state both motivated the robot to seek engagement and expressed itself outwardly so that a human would provide it. When overstimulated, the resulting distress both inhibited engagement and signaled to the human to ease off. The emotion did double duty, organizing the machine’s own behavior from the inside while shaping the human’s behavior from the outside. This is what
