[Purpose/significance] Digital empowerment concerning people’s life and health has an important role in older adults' value realization in their first experience of digital life. From the perspective of affordances, we can under? stand the action possibilities provided by technical features for elderly users, and guide the aging-friendly design of mHealth in terms of value realization and subjective well- being improvement for elderly users. [Method/process] From the technical perspectives of mHealth and the cognitive perspectives of elderly users, this study proposed four ag? ing-friendly affordances, constructed a structural equation model, and conducted an empirical analysis to explore the important role of mHealth’s aging-friendly elements in the realization of personal value and subjective well-being of elderly users. [Result/conclusion] The results showed that there were positive relationships between the mHealth’s ag? ing-friendly affordances and the elderly users’value realization, and the realization of elderly values had a positive im? pact on their subjective well-being. This paper expanded the application of the affordance theory in aging-friendly de? sign and proved the realization way of aging-friendly design for aging users’value realization and subjective well-be? ing from the perspective of practice.
