This chapter details the case studies that were conducted as part of a five-year research project, which conducted the world’s first real-time cross-cultural exchange via the networking of large public screens located in Melbourne and Seoul. The project linked large screens located in Seoul and Melbourne for three media events: SMS_Origins and <Value>, HELLO, and Dance Battle. The chapter details methodological innovations of the research, which involved the reformulation of the way in which the scholar was embedded in the research and transformed according to the interactive research process. It also elucidates critical insights into the process of cultural exchange, the impact of media technologies on public space, and the transformation of the public sphere in the global era. The empirical research generates fresh insights into public interactions with large screens, providing a prototype for future cross-cultural events and offering new theoretical perspectives on the use of public space.
