Cultural heritage is undergoing a technological transformation that has an impact on how people experience, act and relate to cultural heritage found in galleries, libraries, archives and museums. There is a surge in the use of extended reality applications and tools that influence the way people experience virtual artefacts, crafts, traditions and historical stories. Extended reality is used as an umbrella term incorporating immersive experiences that utilise varying degrees of digital visualisation, encompassing virtual reality, augmented reality and mixed reality. Despite the hype around such technologies and the increasingly affordable and enhanced visual experiences they afford, there is still ambiguity in terms of the processes, strategies and human-centred design elements that drive innovation in using extended reality for cultural heritage applications. This chapter proposes a taxonomy that acts as a catalyst for designing features, elements and mechanics reflexively and purposefully for constituting the sense and significance of interaction, participation and meaning-making. The taxonomy could be significant in helping technologists, cultural heritage specialists and educators harness a culture of change when designing and conveying cultural heritage experimentations through extended reality.
