APPLICATION OF KANSEI ENGINEERING IN VARIOUS TRAIN COMPARTMENT DESIGNS TO DETERMINE THE USER'S AFFECTIVE RESPONSE

Abstract

Visual appearance (shapes, colors, materials, and surfaces) applied to product design can provide users with emotional and positive affective responses. The desire of such users will provide essential guidelines for companies to develop products, in this case, trains, in the form of private spaces called compartments. Trains are in great demand for long trips, so there is a need for market segmentation. However, current research only focuses on designs that examine functionality needs. Lack of study of design based on visual appearance, research on user preferences, and more scientific evaluation of design is needed. Therefore, this study aims to translate the user's affective response into the interior design specifications of train compartments with the Kansei Engineering method. This research consists of 5 steps: (1)Determining product semantics (Kansei Words assignment); (2) Define product properties(items and categories), as many as eight design samples; (3) Distributing questionnaires to150 respondents (75 men and 75 women); (4) Data analysis with multivariate statistics, KMO,Barlett's Test, Principal Component Analysis, and clustering of respondents; (5) Evaluate theresults of the most optimal design specifications. The results of this study obtained designrecommendations: straight shape, studio green color, pine wood HPL material texture, anddoff surface. In addition, several user clusters were formed based on gender, age, and monthlyincome to segment train compartments when commercialized. This research is expected to behelpful for the wider community and the development of the interior design of traincompartments.
