/ Abstract / The evolution of humanity, and notably of societies which are composing it, is marked all along its history, by evolutions, verily revolutions, of communication technologies (invention of spoken language, written language, of printing techniques, and so on. . . ). The digital technology and the advent of the Internet are significant steps of this evolution. Nowadays, the impressive development and the intrusion of information technology at every level of the society, at the institutional levels as well as the private ones, bring the need for a new social and societal paradigm based on the knowledge and intelligence economy. This new paradigm includes the concept of Cyberspace to denote the virtual space for human and social exchanges based on human knowledge and experience. Each human being is a center of this paradigm. The individual, owner and retailer of intelligence, is emphasized by her/his own experience. Considering Chisei and Kansei, both cognitive elements of each individual, and descriptive and tacit knowledge, owned by each individual, there is a necessity to consider subjective (or personal) dimension in social communication while designing tools for the Cyberspace. The actual evolution, brought by the new information technologies, makes possible for each individual to share and announce one’s own knowledge with the rest of the group (by extension, with the whole humanity), whatever its size or nature. This is certainly a revolution. This is at the beginning of a new context allowing the design of relevant tools enable to help humanity to understand its common action. This understanding reaches to Collective Intelligence, a new opportunity for human community to progress. Thus there is a real need for new design objectives: creation of tools for Collective Intelligence. Kansei, translated in English as a mental sense of subjectivity, is influencing human relationships. It has an influence on both the ideation and the understanding of interpersonal communication. Thus, Kansei becomes a key point in social context behavior of each individual, influencing not only the social context it-self (its structure and its operation), but also the information flow. Therefore, Kansei Information can contribute to integrate human subjectivity aspects in the design of tools for the Collective Intelligence. Considering these points, the aim of this study is to understand how Kansei Information can contribute to the creation to the creation of a design methodology for Collective Intelligence, and thus to the improvement of communication structures of interdisciplinary workgroups.
