The population is aging, with the percentage of individuals over 60 growing by 3% per year. However, this age group is frequently disregarded in application design. An aging workforce poses challenges for Industry 4.0, focusing on ergonomic, cognitive, and physical aspects. Older users are typically ready to embrace new technology, but fear of making mistakes and an unadjusted user interface slow their progress. This research addresses ergonomic features of user interface design to guarantee that the elderly have equal access to technology and digital services as the younger generation. Using the literature review method, we discovered that the challenges experienced by the elderly are connected to visual, psychomotor, and cognitive limitations. Furthermore, the persona method and user stories were utilized to establish the target population’s application-specific requirements. The goal of this study is to give guidelines for adjusting user interfaces, with an emphasis on enhancing the user experience for the elderly. The user interface was designed following elderly-friendly standards, and presented through a mobile application prototype for healthcare services. The findings of this study revealed which usability elements are crucial for the aging population. Adapting applications to the elderly is an essential step towards a more inclusive and fair society which contributes to the quality of life of the elderly population.
