During recent years the enhancement of information technology via design features borrowed from (video) games, also known as “gamification”, has become a notable development both in academia and industry. Gamification primarily aims at increasing users’ positive motivations towards given activities or use of technology, and thereby, increasing the quantity and quality of the output of the given activities. Business analysts suggest that more than half of all organizations will have gamified parts of their processes by 2015 (Gartner 2011; IEEE 2014). In the academic realm, several studies in various contexts have shown that gamification can be an effective approach to increase motivation and engage users or participants in a given activity (see e.g. Hamari et al. 2014; Morschheuser et al. 2016 for reviews).
