This short article overviews MIREMUS, a theory that formalizes and unifies the abstract description of such mixed-reality museal spaces. Spatial computing devices can mix real space and digital content in a multitude of different ways. MIREMUS provides a systematic description that has been developed with archeological and cultural heritage museums in mind. Emphasis is put on describing changes over time and qualitatively distinguishing between factual artifacts and hypothesized context. Furthermore, MIREMUS is based on a conceptual abstraction of tele-immersion. This enables us to systematically describe novel museum concepts that join multiple real locations with virtual content into one distributed museal space.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing → Collaborative and social computing theory, concepts and paradigms; HCI theory, concepts and models; Applied computing → Collaborative learning; Arts and humanities; Computing methodologies → Mixed / augmented realityHuman centered computing → Collaborative and social computing theoryconcepts and paradigmsHCI theoryconcepts and modelsApplied computing → Collaborative learningArts and humanitiesComputing methodologies → Mixed / augmented reality10.2312/gch.202412524 pages
