With the increasing emphasis on real-world applications of Extended Reality (XR), the field faces growing challenges in creating meaningful, user-centred, and ethical experiences. Understanding how human values have been considered in prior research is essential for ensuring that future XR experiences are designed with a deep awareness of human needs, behaviours, and cultural contexts. This study presents a systematic review of human values in the extant XR literature. It aims to address which values have been explored, how they have been studied, and why they have been considered in XR contexts. We report findings on authors' research motivations, approaches to studying values, application domains, forms of technology, target groups and associated values, as well as identified directions for future research. Based on these findings, we propose a structured analysis that synthesises key trends and gaps, providing a foundation for future research to advance more inclusive, ethically grounded, and context-aware XR design.

Current mixed reality (MR) designs predominantly prioritise functionality and usability, often overlooking individual's diverse value needs. To create more meaningful MR experiences, this paper aims to address this gap by exploring how human values can be integrated into MR design. We propose a values-based design process and evaluate it through three design workshops considering a remote collaborative learning scenario. By comparing our approach to an existing MR application for collaborative learning, we demonstrate how embedding human values into MR design can lead to more ethical and human-centred outcomes. Our findings contribute to advancing the design and application of MR technologies to be more aligned with people's diverse needs and values.

The rapid development of immersive technologies is heralding a shift from purely physical environments to one that seamlessly mixes the physical and the digital. As these Mixed Reality (MR) worlds develop quickly we need to reflect on how human values are incorporated into the design and deployment of the technology. Human values map our perception of the world, reflect attitudes, guide behaviours, and provide us with social and moral grounding. However, there is limited research on incorporating values in the design of MR technologies. This research has three contributions: (1) a playful values-driven workshop design, (2) insights into the values of different groups of people in diverse MR scenarios, and (3) recommendations for incorporating human values for future MR design and application. This work will contribute to improving the ethical and responsible development of current and future MR applications.
