Analysis of the Turkish tulip- shaped tea glass’s emotional design features using Kansei Engineering Methodology

The traditional tulip-shaped tea glass is considered to be a widely used, cultur- ally valued and emotion laden industrial product in everyday lives for people liv- ing in Turkey and it continues to inspire designers for contemporary adaptations. The aim of this study is to identify the emotional design features of the renowned tea glass. The conceptual background of this study pertains to the visceral and behavioral levels of emotional design. The methodology of the study is Kansei Engineering which was developed in the 1980s in Japan to translate consumers’ feelings and perceptions of a product (Kansei) into design elements. In the cur- rent study initially an online survey with 573 participants was conducted to un- derstand the feelings of people towards the tea drinking experience and tea glass. Kansei of the users were collected. Based on the interviews with expert designers, relevant Kansei words and the essential product characteristics for the study were selected. The products with distinct design features were collected from the mar- ket and photographed. Using a semantic differentials scale with 9 Kansei words and 18 product samples, an online survey was conducted with 90 participants. Statistical analysis used as a part of the Kansei Engineering methodology included principal component analysis and ordinal logistic regression. Based on the find- ings of the proposed model, the relationship between the feelings of people and the design features were determined and prepared for the use of industrial prod- uct designers and design researchers.
