TITLE A Real-time Event Architecture to Integrate Cyber and Real Spaces
ABSTRACT

With high speed Internet and advanced digital media technology, the real-time events involving participants from multiple physical locations become reality.

However, most of such events often heavily depend on the specific technology, environment or operation staff's special knowledge and experience. Therefore, current real-time events have problems in sustainability, stability, reproducibility and scalability. Also amount of information shared during the event on the cyberspace is limited compared to the same event on real space. Because of limited information, communication on the cyberspace has restrictions. This research solves such problems by designing the architecture of the realtime event integrating both cyberspace and realspace.

This research proposes "CPARSE (Cyber Physical system Architecture for Real-time and Scalable Events)", an architecture to integrate real space and cyberspace. CPARSE defines communication among event participants and real-time event operation by using its 5 spaces; 1) local-space, 2) primary-space, 3) liaison-space and 4) autonomous-space, are defined for spaces for participants, and 5) operation-meta-space for the operation of the even and management of the communication among participants. Also, it re-defines a media element as a part of the media. Media element enables to describe a variety of participants°« actual communication media usages.

In this research, the incremental development through many actual experiments using CPARSE and its evaluation proved the usefulness. The classical music concert experiment, which uses 3D video and high quality audio as media elements in primary space also uses a part of social media as a media element in liaison space, is a one of the examples of next generation media represented by smart TV. The graduation ceremony and related events right after the Great East Japan Earthquake on March 2011 became a powerful proposal for safe and worry-free society in the information society era in disaster situation. Moreover, the architecture proposed in this research enabled to evaluate past real-time events and abstracted problems from the evaluation. This result helped to improve the quality and operation of the distance learning environment connecting multiple classrooms significantly. It brought great success in inter-university education program based on the sustainable and stable distance lecture environment.
