In age-friendly system design, user experience (UX) testing constitutes a critical phase. The findings from these tests enable developers to refine the system to better align with elderly users’ habits and enhance their satisfaction. As system design paradigms shift from manufacturer-centric to user-centric approaches, companies are increasingly recruiting elderly participants for questionnaires, usability testing, and focus group discussions. This participatory strategy ensures that the final designs more effectively address the specific needs of elderly populations.
