A Reward Design Pattern in BCSS

Abstract. Although constructs have been developed for designing the features of Behavior Change Support Systems (BCSSs), detailed descriptions and gui-delines for their software level implementation are lacking. Through develo-ping software design patterns one is able to examine BCSSs at a more intricate technical level instead of merely a black-box approach to them. In this paper, we present a software design pattern for rewarding users as a way of enhan-cing persuasive human-computer dialogue in BCSS. The resulting pattern contributes to both research on software design of persuasive system features, and for assisting the practical development of such systems
