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

Technological advances are redefining the relationship between physical and virtual spaces. Traditionally, when users engage in virtual reality, they are completely cutoff from the physical space. Similarly, they are unable to access virtual experiences while engaged in physical activities. However, modern multiplatform 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: first, Amplification: one space enhances experiences in the other; second, Complementary: spaces offer different but equally valuable alternatives, and third, Emergence: simultaneous engagement creates entirely new experiences. We propose the ACE cube framework that analyzes these patterns as continuous characteristics, and by integrating this analysis with technical requirements of commercial platforms, we provide practical guidelines for platform selection, technical investment prioritization, and cross-reality application development.
