Research On User Experience Multi-dimensional Evaluation Mechanism And Model For User Interface In Electronic Manufacturing Equipment

User experience is an important measure indicator of user-friendly and high-end in electronics manufacturing equipment. User interface is the support platform of user cognition and operation the electronics manufacturing equipment, which is a multi-channel, multi-platform and complex cognitive interaction research problem. Therefore, the difficulties of design such manufacturing equipment is the information complexity and interaction flow diversification in user interface, causing the user cognitive load overload and the experience problems. Because there is a huge difference in terms of interface characteristics between electronics manufacturing equipment and IT products, the conventional theory is difficult to directly evaluate the user experience in the electronics manufacturing equipment, resulting in the mechanism in the user experience evaluation theory in electronics manufacturing equipment is unclear. In this study, based on eye tracking, semantic differential and other research method, thereby establishing the user experience "cognition-emotion-environment" multi-dimensional influence mechanism; and then construct multi-dimensional algorithm and evaluation function model of user experience based on "design entropy", development of appropriate computer-aided evaluation system.The main works were as follows:The paper establishing the user experience "cognition-emotion-environment" multi-dimensional influence mechanism, details as follows:Firstly, the research studied the design information complexity factor on influence mechanism of the cognitive dimension in user experience. Based on the cognitive ergonomics, the experiment used eye-tracking methods and the questionnaire to gather data. The results showed that:(1) information complexity significantly impacts the user experience; (2) information complexity caused a significant difference in time to first fixation and fixations before; (3) user background significantly affected the visual search strategy, the novice and expert group presented statistical significance in search time performance.Secondly, the research studied the visual design style complexity factor on influence mechanism of the emotional dimension in user experience. Based on semantic differential and kansei engineering, we conducted a semantic differential experimental study. The main findings were as follows:(1) visual design style complexity significantly impacts the user experience, the impact mechanism was inverted U-shaped; (2) The emotional dimension user experience was mainly made up of emotional experience factor and the decorative experience factor, the decorative experience factor and the user experience has a negative correlation. (3) The artificial texture rating has a significant effect on user experience rating.Thirdly, the research studied the situational complexity factor on influence mechanism of the environment dimension in user experience. Based on the environmental psychology and ecological interface design theory, we conducted the SRK and WDA research study. The research was based on the experimental design and NASA-TLX questionnaire to evaluation the user experience. The main results showed that taking into account the environment and situational factors in user interface can make the user more quickly detect and diagnose the user interface problems, significantly better than only consider the popople factor in user interface design.Furthermore, based on the above user experience "cognition-emotion-environment" multi-dimensional influence mechanism reserach, we proposed the entropy theory into the user experience evaluation of electronics manufacturing equipment. Then, we conducted the definition of the "design entropy" theory, as well as the scope and elements of evaluation model and evaluation index system. And then proposed the DEM-MUEEM multi-dimensional evaluation model based on design entropy, constructed the mathematical algorithms and structure. Finally, propose DEM-MUEEM computer-aided software prototype evaluation system. By application of user interface design in typical electronics manufacturing equipment assessments for the case studies and validate the research model. Experiments result showed that the evaluation model can effectively evaluate the user experience, effectively verify the feasibility of the research method. By applying the above method to provide scientific theoretical support in user interface for the evaluation and optimization of electronics manufacturing equipment, effectively expanding theoretical branch in the user experience evaluation in user interface of related digital manufacturing equipment and industrial equipment.
