Game Character´s Active Facial Color Engine based on the Theory of Emotion-Color Association

The graphical expressions and artificial intelligence of Characters have been continuously improving, spurred by the astonishing growth of the game technology industry. Despite such improvements, users are still demanding a more natural gaming environment and reflections of true human emotions. However, the emotions that can be expressed are strictly limited because the facial colors and expressions of current Game Characters are hardly noticeable. Such restrictions can prevent the users from getting into the game. To address this, we developed the Facial Color Engine, which is a combination emotional model based on human cultural theory, emotional expression pattern using colors, and emotional reaction speed function, as opposed to the past methods that expressed emotion through blood flow, pulse, or skin temperature. The reflection of the game character´s emotion on it´s skin color will increase user immersion into the game and encourage further game development using our sensibility engine.
