With the aging trend of the global population becoming increasingly serious and the number of elderly people rising, the health of the elderly has become the focus of social concern. As an important place for the elderly to live, the community has an increasingly urgent need for health testing equipment. The study found that the existing equipment has many deficiencies in terms of functionality and applicability, such as focusing too much on the integration of functions and having a low some functional usage rate, through a visit to 15 brands of equipment in China and five communities in Xi'an City. To solve this problem, this study constructs a leading user identification capability model based on the leading user method, identifies 22 relevant leading users from 84 ordinary users, and explores user needs through observation and semi-structured interviews. Secondly, the device functions were quantified to obtain their priorities through the hierarchical analysis method, which provided the design basis for the health testing devices. The results of the study show that among the functional requirements, blood pressure detection and blood glucose monitoring are regarded as the most prioritized requirements, with a weighting of 0.22. At the same time, the safety requirements are also of great concern, like the disinfection function and the rounded design of the appearance, with a weighting of 0.18. This study provides a basis for the design of health testing devices, which helps to improve the human-computer interaction experience of elderly people when they use them, and also provides a basis for the design of subsequent aging-appropriate products and services. Subsequent R&D of aging-friendly products and services to provide research ideas.
