Abstract (in Japanese) (See Japanese page) 
(in English) Humanoid non-player characters (NPC's) in video games generally behave like a robot performing only their predetermined tasks. Such unnatural behaviors often make the game players feel uncomfortable, and thus prevent their immersion into the video game world. In this study, we attempt to generate natural-looking animated crowd scenes with NPC's each of whose behavior reflects their affection determined from a variety of influential factors. By making use of an arousal-valence model which expresses human affection in two dimensions, we define the affection state of an NPC as a pair of arousal (A) and valence (V) values. For a given scene, our system reproduces interactive audience by classifying individual affection states using a support vector machine network, and then by keeping track of the A-V values for each of the NPC's interacting with one another.
