This study presents "Indispensability" and "Irreplaceability" as new variables for studying the attachment process of digital products that are different from physical products. To analyze this quantitatively, we will set up an integrated model to explore how attachment can be formed through different product-user interactions and time value which are necessary for attachment formation. Analysis of 197 respondents' data for empirical analysis showed that system-centric interactions did not affect the duration of use, whereas user-centric interactions affected the duration of use. In addition, the effects of the period of use on the Indispensability and the Irreplaceability were demonstrated, and the effects on the Indispensability were greater than Irreplaceability.
