With the growing importance of User Experience (UX), Kansei design become the key elements of competitive advantages between products, and consumer demand gradually changes from functional to psychological. As the first medium contacted between consumers’ senses in the process of consumption, previous researches on Kansei engineering have paid more attention to the image of products and materials. Blister packaging is common in the marketspace, and its physical factors and texture changes are rarely discussed. Thus, the purpose of this study is to investigate the correlation between perceived meanings and the hardness of blister package in order to explore the image of blister package through Kansei engineering and establish the relation between geometric form, hardness and the image. The results showed the importance of package hardness on consumer psychology, indicating that the high hardness package provided the sense of luxury and delicate. It is also found that the hardness of tactile is similar with the Fechner law. Meanwhile, geometric perceptions affect sense of touch. Our results contribute to the HCI community by delivering knowledge about the packaging design of interaction.
