| In recent years,China has developed rapidly in the field of lightweight robotic arms.With the rapid development of electronic devices,mobile terminals have also been applied to the development of robotic arm teaching aids.Engineers have eliminated the physical and lengthy control lines of teaching aids and directly developed teaching application software based on computer and mobile terminals.At present,there is a high level of attention paid to the research on the teaching platform of lightweight robotic arms.It is particularly important to improve the efficiency of designers in making reasonable decisions in the evaluation of interaction quality of such platforms,and to improve the interaction quality of such platforms.Therefore,establishing an interactive quality evaluation system suitable for light load robotic arm teaching platforms through scientific research methods,improving the rational decision-making efficiency of designers,is of great significance for the iterative design of such platforms.This article studies the evaluation methods and standards for the interactive quality of the online teaching platform for light load robotic arms.It proposes an evaluation method that combines the advantages of AHP expert evaluation and the objective weighting advantages of entropy weight method,as well as qualitative and quantitative evaluation.It is incorporated into the decision-making system of TOPSIS and a comprehensive decision-making model of AHP entropy weight TOPSIS is proposed,And a feasibility analysis was conducted on the application of AHP entropy weight TOPSIS in the interactive quality evaluation of the light load robotic arm teaching platform.Through preliminary research,feature analysis,user role model construction,work task analysis,workflow analysis,and user experience analysis were conducted on users.Several key elements were obtained from user feedback through expert heuristic evaluation,and the interaction quality evaluation indicators of the teaching platform were obtained based on international standards.Through literature research and preliminary user research,combined with the ISO9126 series standards,an interactive quality evaluation system for the light load robotic arm teaching platform was constructed.Using the quality function deployment theory to analyze the design objectives behind user requirements,identify the key design elements that achieve the design objectives,and use them as the evaluation object of TOPSIS.The AHP expert evaluation method is used to obtain the subjective weight of the evaluation index,the entropy weight method is used to obtain the objective weight for correction,and then the comprehensive weight is obtained through game theory.Finally,TOPSIS is used to solve the relative progress of each design element and the positive and negative ideal solution of the interactive quality evaluation index,and the ranking results of each design element are obtained to guide the design practice.Taking the teaching platform of Haoke light loaded manipulator as an example,the weight of the interactive quality evaluation index and the ranking results of design elements of the teaching platform are used to guide the interaction design and interface design of the platform.The usability test verifies the guidance and accuracy of the interactive quality evaluation system of the light load manipulator teaching platform for the platform interaction design,thus indirectly proving the effectiveness and reliability of the evaluation method. |
