Abstract: User Interface determines the user experience quality of the whole digital twin system.Aiming at the issue of diversified user interface design requirements for digital twin systems resulting from different application scenarios and different user cognition,the information requirements were converted into design element requirements according to the House of Quality (HOQ),and results were corrected allowing the influence of design element interrelationships.Corresponding to the different digital twin application scenarios,the design element requirements weights were obtained to guide the optimal design and improve the usability of user interface.Experiment results showed that the layout order,color contrast and 3D graph were the three most important factors for user interface design of wind turbine energy management digital twin system.The influence of three design factors on the system usability was analyzed by comparing a series of optimization design cases through eye-tracking and other usability test methods,and the validity and feasibility of the proposed method were proved.
