The paper inquires how collaborative services evolve in ubiquitous
network. By comparison study in systems of solutions and interactions of
services, it defines a conceptual framework of spaces of auras in mobilized
collaborative services, proposing four kinds of network and interaction
structures: Peer-to-Peer (P2P), Role-to-Role (R2R), Peer-to-Common (P2C)
and Role-to-Centre (R2C). The conclusion of discussion is that in MCS, the
form of space of auras decides mainly the way of interaction, the structure of
system and degree of relational quality.

Context

The global interest is focusing on the solution to overcome the environmental change as a result of global warming. In the design area, the sustainable design is the key to planning and realizing the eco-friendly and organic structure by avoiding the previous roles of design, which are consumption-oriented and commercial. We discover the social issues for sustainability of the ecosystem with the eyes of designers, and analyze the causes and processes which result in the issues and their social context altogether. For the understanding of sustainability, the wholistic viewpoint to grasp a variety of relations to interact with each other in the social structure is needed, rather than the unilateral view. We have sought after the methods to deliver our views on each and every issue by visualizing the whole process interestingly. Furthermore, we suggested and tried the creative solution to cope with the issues through the design.
