Facial color adaptive technique based on the theory of emotion-color association and analysis of animation

Graphical expressions and artificial intelligence-driven (AI) game 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 currently be expressed are strictly limited because the facial colors and expressions of present game characters are hardly noticeable. Such restrictions can prevent the users from getting fully absorbed in the game. To address this, we developed the facial color change technique, which is a combination emotional model based on human cultural theory, emotional expression pattern using colors, and emotional reaction speed function, as opposed to past methods that expressed emotion through blood flow, pulse, or skin temperature. The reflection of the game characterpsilas emotion on itpsilas skin color will increase user immersion into the game and enrich the playerpsilas experience.
