Immersive mixed reality (MR) in clinical settings is often assumed to improve performance through greater immersion, yet clinical work also depends on efficient information access and task organization. This project examines the tradeoff between immersion and information presentation by comparing egocentric and allocentric interaction styles in clinical scenarios. We propose that these perspectives support different stages of task performance rather than functioning as interchangeable interface designs. In particular, egocentric MR may better support information processing and goal setting, while allocentric MR may better support goal execution, global understanding, and spatial reasoning. This perspective-based framing is informed by emerging XR research suggesting that egocentric views reduce cognitive load, while allocentric views can improve spatial awareness.
To investigate this, we frame clinical workflows in terms of planning and execution phases and evaluate how egocentric and allocentric visualization style affects performance, cognitive workload, and usability. By separating the effects of immersion from the structure of presented information, this work aims to clarify when immersive interaction is beneficial and when externalized information layouts may be more effective. The findings will help guide the design of clinical MR systems that better align visualization strategies with the cognitive demands of healthcare tasks.
