AbstractThis paper introduces the assessment method for ergonomic interaction design reliability of the engineering software operation flow in the field of civil engineering. On basic structure of human reliability assessment index system concerning engineering software operation flow, the approaches of multilevel attribute data analysis were expounded by improved entropy, fault tree analysis (FTA), and Delphi to improve user experience and increase engineering software operation efficiency. This study analyzed the key technologies used to evaluate and improve human reliability of ergonomic interaction design, which is significant for enhancing the application quality of engineering software. Guided by functional requirements, every detail complies with the cognition and feelings of the operator. By considering conscious planning, and design with clear goals, the characteristics of not respecting habits, unfriendly interface, no significant themes, user cognitive load, and the operation error rate can be reduced. User interviews, observation, questionnaire surveys, and other methods were adopted to conduct user research on engineering software interfaces in actual operation. Different interface information architectures were studied to explore user behavior habits and preferences when using engineering software interfaces. The principle of user behavior feedback in interface design should be arranged by multichannel input information so that users can locate and detect the current operation behavior more effectively, improving the user experience and enhancing ergonomic interaction design reliability. Existing problems in the strategic layer of the system were raised through user experience, and the interface design of engineering software was assessed based on nine elements of ergonomic interaction design reliability. Eye-tracker experiments were used to verify the validity and rationality of human reliability assessment based on entropy–FTA–Delphi. The human reliability assessment results of ergonomic interaction design reliability can guide the interface design of engineering software.
