The everyday is often mentioned in design, yet hardly inquired. The everyday is about what is banal, infraordinary, not memorable, as well as about the force that makes things habitual, endotic. In the research encompassing this paper, we question the everyday and explore opportunities to enchant it by design. This paper focuses more specifically on the design of everyday rituals, and aims to propose a descriptive framework to ‘read’ and compose such rituals. The elaboration of the framework is done based on a case study: the making of a hot chocolate in the morning. Through an autoethnographical approach, the main dimensions of the framework are determined (place and time, essentiality, and strength) and discussed. Throughout this inquiry, the value of a first-person perspective while designing for the everyday is discussed, as well as its relationship with the third- person perspective. This framework proposed points out the importance of quick iterations and of the consideration of consequences of design decision at all levels of the everyday ritual (structural, temporal, aesthetical, ethical…).

Next to the well-developed and recognized kansei engineering and kansei science, the discipline of kansei design still appears as emerging and explorative. In this paper, after presenting succinctly the theoretical basis of the first two disciplines, I compare them with and focus more in detail on the bases of kansei design, along with an inspiration in Japanese philosophy and culture. In order to structure further the discipline, necessary for the creation of a robust and specific design framework, I describe the constituents of the discipline, i.e., the notions the designers should take into consideration to either describe and explore kansei through designing, or to reflect upon and validate kansei designs (especially interactivity aspects). Finally, these constituents are illustrated by two kansei design projects showing their value and the current explorations done on the topic of interactive materiality in kansei design.

For over three decades, kansei engineering has expanded greatly and has become a significant discipline both in the industrial and the academic worlds. In this paper, I present the current situation of kansei engineering, and plead for the emancipation of other disciplines, as part of kansei research as well. By reconstructing the historical path of kansei research and exploring the variety of disciplines within kansei research, I point out the opportunities for kansei design to emerge. Whereas kansei engineering and kansei science have found their roots in scientifically established approaches (respectively engineering and brain science), kansei design intends to return to earlier Japanese philosophical or cultural works to rediscover the essence of kansei, and to use them as inspirational means for design. This new discipline certainly needs to be elaborated further. Therefore, this paper aims to contribute to the elaboration of a more expansive point-of-view in design research regarding the relationship between human beings and their immediate environment.


Involving psychophysiological knowledge in Kansei design

Involving psychophysiological knowledge in Kansei design

paper

This paper introduces a design method using psychophysiological research output as an inspiration means for the design of products taking user?s Kansei highly into consideration. The development of this method is itself a part of a series of design methods based on the collaboration of the research fields of psychophysiology and design. As case studies, two design projects following this process are introduced. Firstly, the colourful rain umbrella lets its user to experience grapheme-colour synaesthesia. Secondly, the sensorial socialising smartphone informs about the user?s digital social network activity by the means of warmth, a non-invasive tactile technique. Informed by psychophysiological literature, this design is shown to be not only informational of the network activity, but also motivational towards greater social experience. This approach enables psychophysiology not only to inform and support design ideation, but also to enrich the value of the design concept by bringing new arguments.

paper

In order to describe emerging methods and means for Kansei design, this paper overviews three approaches involving an intense collaboration between the fields of design and psychophysiology:

  • The use of tools built for psychophysiology and of techniques based on constructivist psychology theory, in order to support designers ‘inspirational work focusing on human beings’ behaviors, experience, and mental constructs.
  • The use of knowledge created by psychophysiological research as an inspirational source of knowledge and as a conveyor of it for all along the design process. This approach takes into account the latest scientific progresses in psychophysiology, and concerns greatly about the scientific nature of the considered knowledge.
  • The use of psychophysiology tools to complete design requirements. Each approach presented here is supported by an applicative example. These interdisciplinary approaches lead towards the structuring of Kansei Design as an application field of Kansei Science.

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.
