Research On Product Interface Design Based On User Cognitive Ability Inclusion

As our society further development in technology,the popularization of intelligent products brings people oceans of convenience.More and more product interfaces are lively in the public.The information displayed by the interface not only enriches people’s visual feeling and improves the use efficiency,but also provides high-quality interactive experience.However,due to the increasingly complex product functions,a host of users are at a loss in face of many functions derived from intelligent products,or even leave out.Product interface is a medium for users to interact with product information,whose flaws and advantages have a direct impact on users’ experience.Cognitive ability is the core ability for users to operate product interface.Therefore,how to improve the inclusiveness of users’ cognitive ability has become significant part in the research of interface design.In the first place,the superiority of inclusive design theory is demonstrated by comparing with similar theories.We may draw a conclusion that the research of cognitive ability is of great importance in the Era context.Referring to the theories and experiments of different scholars,this paper summarizes the types of cognitive ability and clarifies the internal and external factors that affect cognitive ability.Secondly,research institutions at home and abroad have expounded the principles of inclusive design from varied perspectives.Combined with the cognitive ability of users,they summarized the principles of inclusive design which shows easy use and full guidance,moderate function and humanistic care.What’s more,this study integrates the design cases and proposed the inclusive design strategy which reduce the difficulty and complexity of cognitive ability.Besides,this paper analyzes the evaluation index of users’ cognitive ability in the existing research,extracting estimating index in expert interviews.It sets the relative importance of the indicators in the overall evaluation,and constructs the product interface evaluation system based on the cognitive ability users and defines the design process and methods.Thirdly,choosing the microwave interface as the carrier of practice,this paper analyzes the physiological function and needs of the new and old people.Combining the product interface evaluation system,it analyzes different user models,and excavates the rejection phenomenon existed in the interface from the use process,and extracts the rejection points of the user’s cognitive ability.Fourthly,corresponding the rejection points to the five levels of user experience,it optimizes the design of the microwave oven interface according to the proposed design principles,strategies and procedures.Finally,inviting the target user to conduct experiments after producing the high-fidelity interface.The experimental data is compared with the sample microwave oven interface to verify that the optimized interface has a significant increase in user cognitive tolerance.Furthermore,it also verifies the rationality and effectiveness of the design process.From the perspective of users’ cognitive ability and basis of the inclusive design theory,this study proposes the design principles,adjustment strategies and evaluation system in terms of users’ cognitive ability,so as to further expand the scope and depth of the research on inclusive design theory and enrich the product interface design theory.By means of the design practice,we can optimize the interface design of microwave oven,and verify the application of theory,which provides reference for the theoretical and practical research of product interface design in the future.
