Research On Ergonomics Design Elements Affecting Effectiveness Of Lunar Rover Human-Automation Collaborative Task

The improvement of automation system capability brings new challenges to the human-machine cooperation of lunar rover.In order to develop a human-automation system to support this kind of cooperation safely and effectively and improve the cooperative operation effectiveness,it is necessary to study the influencing factors of the human-automation cooperative task effectiveness of lunar rover.On the basis of identifying the influencing factors and evaluation indexes of the lunar rover humanautomation cooperative task effectiveness,this thesis explores the relationship between design elements and cooperative task effectiveness and analyzes the mediating effect of automation trust and reliance on the relationship between key design elements and cooperative task effectiveness.The main work completed in this thesis is as follows:(1)The influencing factors and evaluation indexes of the lunar rover humanautomation cooperative task effectiveness are identified.Conducted a lunar rover humanmachine collaborative task analysis,has been clear about the characteristics and the basis of finishing the tasks corresponding experimental paradigm,on this basis,the existing human-automation collaborative task effectiveness influence factors and the screening evaluation index set,determine the 8 design elements such as the degree of automation,automation of trust and reliance two intermediary variables,and three evaluation indexes such as situational awareness,a human-automation cooperative task effectiveness model of the lunar rover is constructed.(2)The relationship between ergonomics design elements and human-automation cooperative task effectiveness of lunar rover is studied.Based on the basic experimental paradigm and the efficiency relationship model of the human-automation collaborative task of the lunar rover,the relevant literature were searched,screened,and coded,and a dataset containing 165 studies and 463 effect sizes was constructed.On this basis,the meta-analysis method is used to analyze the relationship between ergonomics design elements and the effective index of the lunar rover cooperative tasks,and at the same time,the selected ergonomics design elements are further tested.(3)The key design elements influencing the effectiveness of the human-automation cooperative task of the lunar rover are determined.Combined with the results of the metaanalysis,the entropy weight method was used to comprehensively evaluate the influence of various design elements on the collaborative task effectiveness.The key ergonomics design elements influencing the collaborative task effectiveness of the lunar rover were identified as skill level,working memory,degree of automation,transparency,task load,and time pressure.(4)The mediating effects of automation trust and reliance on the relationship between key design elements and lunar rover human-automation cooperative task effectiveness are studied.The correlation coefficient matrix of key design elements,automation trust and reliance and evaluation index is constructed.The intermediary effect of automation trust and reliance on the relationship between key design elements and cooperative task effectiveness is tested by structural equation model.The results show that key design elements directly affect the cooperative task effectiveness of lunar rover,it will also indirectly affect the lunar rover cooperative task effectiveness through the intermediary role of automated trust and reliance.Finally,based on the above research results,this thesis discusses the design of the human-machine cooperative task of the lunar rover from the aspects of the humanmachine function distribution,human-machine interface,task flow,etc.this article research results to improve the comprehensive effectiveness of lunar rover humanmachine collaborative task and optimize the human-machine interaction system is of great significance for design.
