Tracing the Scenarios in Scenario-Based Product Design: a study to support scenario generation

Scenario-based design originates from the human-computer interaction and\ud software engineering disciplines, and continues to be adapted for product development. Product development differs from software development in the former’s more varied context of use, broader characteristics of users and more tangible solutions. The possible use of scenarios in product design is therefore broader and more challenging. Existing design methods that involve scenarios can be employed in many different stages of the product design process. However, there is no proficient overview that discusses a\ud scenario-based product design process in its full extent. The purposes of creating scenarios and the evolution of scenarios from their original design data are often not obvious, although the results from using scenarios are clearly visible. Therefore, this paper proposes to classify possible scenario uses with their purpose, characteristics and supporting design methods. The classification makes explicit different types of scenarios and their relation to one another. Furthermore, novel scenario uses can be referred or added to the classification to develop it in parallel with the scenario-based design\ud practice. Eventually, a scenario-based product design process could take inspiration for creating scenarios from the classification because it provides detailed characteristics of the scenario

User kansei modeling and eco-design

The use of day-to-day life artifacts is a key phase in the lifecycle of products. Indeed it has a great impact on our environment. User centered methods are not yet taken into account in eco-design approaches. These methods are being developed in two ways, by building new user models encompassing complex dimensions such as Kansei and experience, including values and moods, and by integrating the user himself in the design process. This paper deals with setting-up a new theoretical framework associating user-centered design advanced approaches such as experience design, Kansei studies, or participative design and eco-design methods. The final goal is to support product design by providing some guidelines according to environmental issues linked to the users and their abilities

Immersive moodboards, a comparative study of industrial design inspiration material

A recent trend in our industrial culture has been the gradual emergence of digital tools in various fields of human activity. They aim to reduce development time, cost, or to insure a low error, high quality process. Many fields have been improved thanks to this new computerized approach. This paper is centered on how industrial design could be assisted by virtual reality tools. More specifically it presents a new vision of early design methodologies through immersive technologies. It also presents the results of an experimentation aiming to compare traditional moodboards with a newly developed immersive moodboard. When analyzing and comparing the relationship of the industrial designer to a traditional and an immersive moodboard, our result highlights the fact that immerging the industrial designer in an immersive moodboard induces a high emotional activity without radically modifying the meaning of the represented trend. The moodboard data spatialization stimulates and engages the designer into interacting with the immersive moodboard. The virtual reality system provides the illusion of a potential reality, which can be used by the designer as a reflection basis for his work. We believe that delivering this immersive experience during the early design process will help the industrial designer make style related decisions.Projet CARNO

Trends integration process as input data for Kansei Engineering Systems

This paper aims at studying new ways of users integration in “emotional Design” or “Kansei engineering systems”. The main goal of this study was the integration of the trend factor in design, with an early emotional evaluation of “Trend cards” produced by the designers. After a definition of the study context, we explain the experimental protocol which was followed. It was based on a questionnaire method involving 56 French subjects and applied in the field of shoes design. The data analysis was mainly proceed by the way of a Principal Component Analysis. The expected results were centred on the emotional evaluation of the Trendcards in order to establish further design rules for a Kansei Engineering system. In conclusion, we can recognize important semantic effects and influences which can be used as information for the implementation of the design elements data base

ヨリヨイ ユーザー タイケン ノ タメ ノ デザイン プロセス ニ オケル カンセイ

Based on the Japanese notion of ‘Kansei’, this research explores two sets of interrelated questions: 1) What are the ways in which the anticipated user experience, namely the emotional responses of target users, deliberately influence the design decision-making process? 2) How can Kansei help designers to predict these responses more precisely, and which methods and tools can help them to do so? The research findings in this article is more concerned with the broader understanding of design, the design/creative process, and its prospective influence points regarding the implementation of the Japanese ‘Kansei’ philosophy in the design process, which bares great potential for the improvement of User Experience design – a cross-disciplinary perspective to all fields of design. The article concludes with an extended model named “Emotional Response Sensitive Design Process” that provides guidance and tools supporting a ‘Kansei-induced’ design decision-making process

The Extended Framework of Kansei Engineering, Kano and TRIZ Applied to Logistics Services

As one of the most rapidly growing service sectors in today’s business, providing excellent quality in logistics services is a must. In services, recent research shows that affect/emotion (known as Kansei) and Kano’s attractive performance are deemed to be sensitive in dealing with total satisfaction, rather than usability and functionality. However, the ideas for service improvement are often contradictory. Hence, this study proposes an integrated model of Kansei Engineering and Kano incorporating TRIZ (Teoriya Resheniya Izobretatelskikh Zadach) which contributes to the improvement of logistics services. A case study in IT-based logistics services has been conducted. The service attribute ‘cleanliness of helmet for customer’ has been regarded as the most critical, which dealt with Kansei professional, innovative, cheap, and precise. In addition, the modularity-based helmet cover and inner sponge has been proposed for TRIZ-based improvement. Keywords: Kansei Engineering, Kano, TRIZ, logistics service

Towards a model of how designers mentally categorise design information

This study aims to explore how designers mentally categorise design information during the early sketching performed in the generative phase. An action research approach is particularly appropriate for identifying the various sorts of design information and the cognitive operations involved in this phase. Thus, we conducted a protocol study with eight product designers based on a descriptive model derived from cognitive psychological memory theories. Subsequent protocol analysis yielded a cognitive model depicting the mental categorisation of design information processing performed by designers. This cognitive model included a structure for design information (high, middle, and low levels) and linked cognitive operations (association and transformation). Finally, this paper concludes by discussing directions for future research on the development of new computational tools for designers

Emotional Design: An Overview

Emotional design has been well recognized in the domain of human factors and ergonomics. In this chapter, we reviewed related models and methods of emotional design. We are motivated to encourage emotional designers to take multiple perspectives when examining these models and methods. Then we proposed a systematic process for emotional design, including affective-cognitive needs elicitation, affective-cognitive needs analysis, and affective-cognitive needs fulfillment to support emotional design. Within each step, we provided an updated review of the representative methods to support and offer further guidance on emotional design. We hope researchers and industrial practitioners can take a systematic approach to consider each step in the framework with care. Finally, the speculations on the challenges and future directions can potentially help researchers across different fields to further advance emotional design.http://deepblue.lib.umich.edu/bitstream/2027.42/163319/1/Emotional_Design_Manuscript_Final.pdfSEL
