"Usability" while a products is in active use is the main focus of the design process. However, it is getting difficult to measure the value of products. In recent years, the meaning of user experience (UX) has expanded to cover not only use but also the whole spectrum of before use to after use. In this study, we focused on after use, and tried objectively evaluating "attachment." First, we marshaled that psychological state of attachment and constructed 10 subjective indexes. Next, we presented each user with images of products, and measured those 10 subjective indexes and the subjects' physiological reaction. The results of the analysis suggest that cerebral blood volume in the DLPFC and the MPFC, plethysmography amplitude may be valid objective indexes that detect the degree of attachment.
