| Since the middle and late 1990 s,user-centered design concepts and user research methods have gradually emerged and received more attention.User needs have become product improvements,product innovations,and user satisfaction enhancements to achieve success in the market.foothold and breakthrough point.As a systematic user research method,the user mental model integrates various methods to dig deep into the user’s behavior and inner true thoughts,which is helpful for designers to understand user needs and value tendencies for certain types of products,and realize product optimization and optimization for designers.The rapid development of the enterprise provides scientific methods and basis.This study synthesizes the effective data obtained from human factors engineering experiments and the value information obtained from the user’s mental model,and takes the optimal design of the waist support leisure chair as a practical case to design a waist support leisure chair that meets the needs of users in terms of product attributes and user experience.Help relieve young people’s health problems such as lumbar discomfort and lumbar muscle fatigue caused by sedentary work.The project combines the qualitative research method of the user’s mental model with the quantitative research method of human factor experimental data,making the product design closer to the user,and expanding the user-centered theoretical research of the mental model in depth and breadth,and also for The product design combining quantitative and qualitative provides reference and tools for reference. |
