Affective Computing for Computer Games

Just like traditional AI applications game AI mainlyfocuses on rational inference. But in the real world humandecision making is not only involving rationality but also sense. Inthis book we propose an architecture for the bot designers toinclude affective computing in a game bot by attributing emotions tothe bot. The architecture is based upon a variety of theoriesincluding the famous OCC model. It treats Joy Fear AngerDisgust and Distress as five basic emotions. It uses three emotionalvariables namely Desirability of an event Blameworthiness orPraiseworthiness of an action and Appealingness of an object to evaluatehow a specific emotion is affected by the environment. In additionto an ordinary Rational Action Engine which controls the rationalbehavior of a bot we add an Emotional Action Engine in thearchitecture to make the emotional behavior possible. An Action Arbitratoris equipped to decide given a specific time and space whether abot should follow the rational or emotional inference. The arbitratorsimulates how humans solve the conflicts between reason and emotion.
