Research On Interaction Design Of Elderly Smart Bracelet Based On User Behavior Logic

With the rapid development of economy and technology,smart products represented by smart bracelets for the elderly have provided solutions for smart retirement.However,the current research of smart bracelets for the elderly are mainly focused on functional innovation and technical implementation.There is a lack of research on human-computer interaction methods.The complex information and unfriendly interaction methods of existing products have led to resistance among elderly users.From the perspective of user behavior logic,this paper combines cognitive experience,behavior habits with the elderly smart bracelet interaction design to reduce the learning,cognition,and operation costs of elderly users.Firstly,this paper sorts out the relevant theories of behavioral logic,and combined with case analyzes its specific content into four aspects: goal orientation,perception and cognition,experience and habits,and reinforcement and restriction.Then this paper summarizes the current status of the development of smart bracelets,focuses on the design features of smart bracelets at the physical logic level and the behavior logic level.On this basis,the relationship between behavioral logic and the interaction design of the elderly smart bracelet is analyzed,and the methods and values of behavioral logic research for the elderly group are clarified.Secondly,the logical characteristics of elderly user behaviors are extracted.Through research methods such as user interviews,behavior observation,and task-based behavior experiments,combined with the specific content of behavioral logic theory,this paper summarizes the characteristics of behavioral logic of elderly users,and discusses the performance and impact of behavioral logic when elderly users use smart products.Finally,the association and matching between behavioral logic features and interaction design elements are constructed,and the corresponding levels of association and matching are proposed from four levels of functional content,information architecture,operation mode and visual performance.Starting from the characteristics of the behavioral logic of the elderly users,the design strategy is transformed into a specific interactive design practice path,the interactive design practice of the elderly smart bracelet is completed,and the usability test is used to verify the feasibility of the methods and strategies.
