美国人机工程专家Charles C.Wood给人机工程下的定义是:“设备设计必须适合人的各方面因素,使人在操作中付出的代价最小,获得的效率最高。”由此可见,人机工程研究的核心问题是人机之间的相互关系,也就是研究如何从人的生理、行为特性和机器特性出发,充分发挥人和机器的作用,以提高系统的效率。 Ergonomically, Charles C. Wood, the American ergonomics expert, defined it as: “The design of a device must fit into all aspects of human being, minimizing the cost of operation and maximizing the efficiency.” Thus, people The core issue of machine engineering research is the interrelationship between man-machine, that is, how to study human’s physiological and behavioral characteristics and machine characteristics, give full play to the role of people and machines in order to improve the efficiency of the system.
