Cross-Reality Lifestyle: Integrating Physical and Virtual Lives through Multi-Platform Metaverse

Abstract: Technological advances are redefining the relationship between physical and virtual space. Traditionally, when users engage in virtual reality (VR), they are completely cut off from the physical space; similarly, they are unable to access virtual experiences while engaged in physical activities. However, modern multi-platform metaverse environments allow simultaneous participation through mobile devices, creating new opportunities for integrated experiences. This study introduces the concept of "cross-reality lifestyles" to examine how users actively combine their physical and virtual activities. We identify three patterns of integration: 1) amplification: one space enhances experiences in the other; 2) complementary: spaces offer different but equally valuable alternatives; and 3) emergence: simultaneous engagement creates entirely new experiences. By analyzing commercial platforms, we create a technical framework that addresses content design, platform infrastructure, and device interfaces. This framework guides the development of cross-reality applications while demonstrating how metaverse technologies blur the traditional boundaries between physical and virtual experiences.
