Abstract [en]

Launching products successfully onto today’s markets requires not only good quality and usability for a reasonable price but also that the customer gets a good subjective impression of the product. This is especially true for mature products, which tend to be rather similar to competing products. Designing a good feeling into products is a challenge many companies face today. A new research field is named emotional design or affective engineering. One method within this field is Kansei Engineering, a methodology that can quantify user impressions mathematically. A general procedure for conducting Kansei Engineering studies has been proposed, but still much expert knowledge is necessary for those studies. Therefore, software tools facilitating this process have been developed. In this paper, two tools used at Linköping University are presented. It can be seen that those tools deliver good results and remove many obstacles for applying Kansei Engineering in companies. However, more research is needed on the theoretical bases and extraction methods.

Abstract [en]

There is an increasing emphasis on developing systematical research approaches for design of products that appeal to people’s emotions and values. This thesis proposes methodological developments for investigating people’s subjective emotional needs and values towards quality and explores interactions of related physical design attributes for product design.

The overall aim of the licentiate thesis is to gain an understanding on Affective engineering of products through exploring the concept of quality feeling and to develop methodological approaches for this. Quality feeling can be described as a holistic concept considering individuals’ perceptions, expectations, experiences, physical and psychological expressions for a product or service. Affective Engineering methodology aims at translating human psychological processes, such as feelings and emotions, into appropriate product design attributes, such as size, shape, and surface characteristics.

The thesis presents three methodological approaches when evaluating products for affective engineering and one approach for an interactive product design support system development.

The first study presented deals with feelings of quality for reach truck operator’s cabin components. Components that would convey to give a higher total quality feeling were identified and improvement opportunities were prioritized. The second study presented is based on developing an interactive affective design and decision support system software for design of the steering wheel from drivers’ individual and shared preferences. In the third study affective values arising from judgments for important feelings of quality is the study basis. The author presents research on identifying interactions of design attributes for affective values in waiting areas of primary health care services.

Further, a new approach for applying Affective Engineering in design of complex contexts is proposed.The proposed approach aims to handle contexts where feelings and design attributes have complex interactions for products and services that give almost an infinite number of design alternatives that are difficult to handle in traditional Kansei Engineering studies. With this thesis also an interactive product design and decision support system software is developed for steering wheel design and proposed for educational and industrial use. The proposed system works based on linking product design attributes to human feelings by applying Genetic algorithms and provides potential basis for future product development and improvements.

This thesis has also contributed with affective design recommendations applicable for vehicle cabins and waiting areas in primary health care. Moreover, a number of existing methods in Affective Engineering have been tested and methodological experience is drawn, including advantages, disadvantages and limitations of using these methods.
