The aim of this study is to investigate the main factors of tactile image felt on a product and which form properties will influence these tactile image factors, then, to classify products into different tactile image styles. Thirty subjects (15 males and 15 females, and all of them are master students of design) were recruited in this study to make the semantic differential evaluation with 12 image word pairs on 26 cups. Factor analysis was conducted on the collected data to reveal three main factors of tactile image of products, which are decorative factor, affinitive factor and quantity factor. The relation between factors and form features of cups was examined by correlation analyses. It was found that the external factor was affected by the feature of bump and gap of cup; the affinitive factor was affected by the feature of smoothness and temperature of cup; the quantity factor was affected by the feature of rigidity of cup. Finally, we categorize five tactile-image styles by using cluster analyses (K-means) which are decorative, quantity, simple, gentle and none image styles. The results of this study can help designers to design products with demanded style of tactile image.
