  abstract = {Many interesting social studies can be done by asking people about what they think, feel or experience the moment certain events occur in their daily lives. These studies can be conducted based on the event-contingent protocol of the Experience Sampling Method. We have implemented this protocol in Crowdpinion {\textendash} our software tool consisting of a web panel where the researchers can set up and control their studies and a mobile app for the responders. In order to extend the users{\textquoteright} motivation beyond the will to contribute to research, we have applied some gamification elements based on fostering curiosity by gradually revealing the big picture from the overall study. In this paper we describe the concepts of Crowdpinion as a research tool, our approach to gamification, how we tested it in the beta version and present plans for future improvements.},
