In order to understand how the texture combination influence emotions, we take timber textures and stainless steels as examples. In experiment 1, we used 13 emotion scales to investigate the emotion of 14 timber textures; in experiment 2, we invited 31 well-educated observers to investigate the prototypes of desk; in experiment 3, we combined 14 timber texture textures and 2 stainless steels textures (mirror, matte), and used 6 emotional vocabularies to evaluate. We found that in experiment 1, we obtained 3 factors of timber texture textures and they can be categorized into 4 categories; in experiment 2, the features of a desk includes: timberen desktop, drawer, stainless legs and grips of the drawer; in experiment 3, after combining timber textures and stainless stainless steels, we might change the emotion of timber texture. The results showed that the practical product and prototype combination have the same influence to observers’ emotions. In other words, we can presume the emotion induced by practical products through the emotion of texture observation on prototype combination.
