Design And Construction Of Teaching Platform For Ergonomics Experiments

With the continuous development and popularization of information technology,comprehensive information technology has become the inevitable development requirements of this era,especially in the field of education,comprehensive information education is more and more widely used.In this paper,the human-machine engineering experiment course and information technology are combined to build the human-machine engineering experiment teaching platform,to explore the optimal processing method and presentation mode of experimental data,to build the evaluation of human professional ability,to study the relationship between human-machine characteristics and professional classification,and to lay a good foundation for students to better learn the subject of human-machine engineering.First of all,compare various demand analysis methods to determine the demand analysis method of human-machine engineering experiment.Through in-depth interview,questionnaire survey and literature search,obtain the needs of different users for humanmachine engineering course.According to the evaluation index of network course,these needs will be classified and screened.The screened needs will be analyzed by Carnot analysis to analyze the quality characteristics of each demand It provides the basis for the design of the teaching platform of human-computer engineering experiment.Secondly,we plan and design the basic experiment content of human-machine engineering,mainly including the use of experimental instruments,the design and exploration of experimental thinking questions and the expansion and application of experimental content;standardize the data processing methods of basic experiment of human-machine engineering according to the experimental requirements,including the general algorithm of various experiments and the difference algorithm of different experiments,According to the determined algorithm to draw the algorithm flow chart;design a variety of experimental data visualization methods,through the way of questionnaire to determine the visualization of the final experimental results.Thirdly,the content of vocational ability experiment is designed,that is,vocational ability evaluation.Based on whether students have design talent as the evaluation standard,build a comprehensive evaluation of professional ability,sort out the previous students' ergonomic data as the experimental data;use PCA method to reduce the dimension of human factors features,build a weight model,determine the more important features that affect whether students have design talent,verify the robustness of important features through relief algorithm;use SVM classification The algorithm classifies the data and evaluates the performance of this algorithm.Finally,according to the user needs and the final algorithm of human-machine engineering experiments,the framework of human-machine engineering experiment teaching platform is built,including the functional framework and operation process framework;based on the user experience elements,the strategy layer,scope layer,structure layer,framework layer and performance layer of human-machine engineering experiment teaching platform are designed;the usability test of this platform is sought for the subjects,design the test task,find out the existing problems of the platform,and improve it to improve the design of the human-machine engineering experiment platform.
