Creating Mixed Reality applications poses distinct challenges for development and design. One of the challenges is designing Mixed Reality application-specifc experiences in the wild. In this paper, we present a structured refection approach to revisit projects from the past. In applying this structured refection to the data collected during a nine-month industrial project, we unveiled the Virtuality-Reality Clash. To generate a sufcient data corpus, we structurally analysed git commits, tickets, emails, handwritten notes, and weekly snapshots of the 3D designs. The clash could be narrowed down in our data corpus to the situations in which we were fusing the real environment with the virtual content. Finally, we could fnd fve design patterns for MR experience. With these patterns, we aim to help developers and designers of MR applications identify situations where Virtuality and Reality clash and propose approaches to address them.
