User centric Requirements for Enhancing XR Use Cases with Machine Learning Capabilities

The combination of Extended Reality (XR) and Machine Learning (ML) will enable a new set of applications. This requires adopting a user-centric approach to address the evolving user needs. This paper addresses this gap by presenting findings from two independent focus groups specifically designed to gather user requirements for two use cases: (1) a VR Conference with an AI-enabled support agent and real-time translations, and (2) an AR Theatre featuring ML generated translation capabilities and voice-activated VFX. Both focus groups were designed using context-mapping principles. We engaged 6 experts in each of the focus groups. Participants took part in a combination of independent and group activities aimed at mapping their interaction timelines, identifying positive experiences, and highlighting pain points for each scenario. These activities were followed by open discussions in semi-structured interviews to share their experiences. The inputs were analysed using Thematic Analysis and resulted in set of user-centric requirements for both applications on Virtual Conference and Augmented Theatre respectively. Subtitles and Translations were the the most interesting and common findings in both cases. The results led to the design and development of both applications. By documenting user-centric requirements, these results contribute significantly to the evolving landscape of immersive technologies.
