Through this chapter, the authors aim at describing Gamification—the use of game elements in non-ludic environments—to identify its limits and lacks as well as its assets. Indeed, it has been developed to answer a need that arouses out of the Human Computer Interaction (HCI) field evolutions, and it could be valuable in that scope. The authors propose a definition of Gamification according to several different dimensions that are part of the HCI design field. They suggest it as a first step towards a guiding design framework aimed at designers. They mention future research directions that would help in going further and enriching the framework, leading to the creation of a design model for user experience design through Gamification. The authors finally raise some ethical concerns about the meaning of Gamification itself.
