Many virtual and alternate reality projects create narrative experiences in the digital medium. These are Interactive Digital Narratives (IDN), a form of expression at the intersection of different artistic approaches, research fields (humanities, computer science), and emerging technologies (e.g., artificial intelligence, virtual reality, generative content), with a wide potential for different applications. A key element towards fulfilling this potential is the creation of a satisfying user experience. In this paper we present a toolbox for the evaluation of the user experience that connects which enables the systematic and quantitative study of IDN user experiences.
