An Angry Birds-like Game System for Promoting Players’ Emotion

This paper presents a system aimed at encouraging players to smile when playing an Angry Birds-like game by generating levels whose designs look like pixel images and explicitly requiring the players to smile to see such levels. Our system consists of two major parts: level generator and game system. The level generator generates a level according to a given file that defines the level appearance of a pixel image. The game system includes emotion recognition and fog control; to encourage the player to smile, fog is first generated that covers the game screen, but when the player smiles it will gradually disappear. It is expected that the proposed system is useful in promoting the affect of its players, i.e., increasing the positive affect and decreasing the negative one.
