Research on Aging-Friendly Design Evaluation Model of Wearable Devices Based on Implicit Interaction Theory

In order to evaluate the degree of Aging-friendly of wearable device, an evaluation model of wearable device Aging-friendly design based on implicit interaction is proposed from the group characteristics of elderly users to improve user experience. The influencing factors are collected and integrated through literature research and user interviews, and the influencing factors are modified by combining with expert scoring to construct a hypothetical model with 33 evaluation indicators. The influencing factors were transformed into measurement indicators and measurement questions, and the model was revised through pre-investigation data analysis to finalize the evaluation model of 31 evaluation indicators, and the evaluation model was verified through formal investigation data analysis. Taking Xiaomi bracelet as an example, the evaluation model was used for case practice to verify the applicability and validity of the model. The study shows that the evaluation model of wearable device Aging-friendly design based on implicit interaction can accurately obtain the evaluation of wearable devices used by elderly people and locate the design optimization points, which can effectively meet users’ experience needs.
