Assessing User Experience and Cognitive Workload in Virtual Reality Digital Storytelling

This article examines the user experience and cognitive workload in digital storytelling through immersive virtual reality (VR). Specifically, it explores the relationship between various aspects of the user experience and their link to the cognitive workload. The investigation was conducted by means of a large-scale evaluation of an underwater archaeological VR experience that simulated diving into the reconstructions of a submerged ancient site combined with interactive 360° video storytelling. The evaluation included 125 participants from two different geographical locations. Results revealed a strong interdependence between all user experience scales, including presence, immersion, engagement, emotional response, state of flow, subjective judgment, and technological adoption of the VR equipment. Moreover, the sense of presence in VR was strongly related to the reported task performance. The article highlights the importance of understanding the user experience and cognitive workload when creating digital storytelling applications in immersive VR.
