Despite widespread availability, the use of smart devices is still very limited among seniors who could benefit from adopting these systems. This research-in-progress study draws on the theory of aging and subjective assessments of health, as well as information systems adoption literature to propose a theoretical model to explore the effects of older adults’ cognitive age on their disability perceptions which can influence their adoption of smart devices. The results will be achieved using a combination of qualitative and quantitative methods. Potential contributions from this research to theory and practice are also outlined.
