Creating Informal Learning and First Responder Training XR Experiences with the ImmersiveDeck

In recent years eXtended Reality (XR) technologies have matured and have become affordable, yet creating XR experiences for training and learning in many cases is still a time-consuming and costly process, hindering widespread adoption. One factor driving effort is that content and features commonly required by many applications get re-implemented for each experience, instead of sharing and reusing these resources by means of a common platform. In this paper we present two XR experiences in the context of informal learning and first responder training along with the shared platform they have been created with and the creation process. Furthermore, we have technically evaluated relevant parts of the platform for feasibility of use with experience requirements and confirmed ap-plicability. Finally, we present an informal expert evaluation of the content creation process's user experience for the informal learning experience along with guidelines derived from the findings.
