This article reviews some ergonomic factors associated with agricultural guidance displays. Any technology or management decision that improves the efficiency of an agricultural operation can be considered an aspect of precision farming. Agricultural guidance displays are one such tool because they help to reduce guidance error (i.e., skipping and overlapping of implements within the field), which result in improper application of crop inputs at increased cost. Although each of the guidance displays currently available functions using a different principle, their key objective is to communicate useful guidance information to the operator of the agricultural machine. The case with which the operator obtains the required information depends on a number of ergonomic factors, such as color perceptibility, flash rate, attentional demand, display size, viewing distance, and height of placement of the display in the cab. Ergonomics can be defined as the application of knowledge to create a safe, comfortable, and effective work environment. Consequently, it is critical to consider ergonomics when designing guidance displays or when locating a display in the tractor cab. Without considering ergonomics, it is unlikely that the efficiency of the human-machine system can be optimized.
本文回顾了一些与农业导航显示器相关的人体工程学因素。任何提高农业作业效率的技术或管理决策都可被视为精准农业的一个方面。农业导航显示器就是这样一种工具，因为它们有助于减少导航误差（即田间农具的漏耕和重叠），而这会导致作物投入的不当施用，成本增加。尽管目前可用的每种导航显示器的功能原理不同，但其主要目标是向农业机械操作员传达有用的导航信息。操作员获取所需信息的难易程度取决于许多人体工程学因素，如颜色感知度、闪烁频率、注意力需求、显示器尺寸、观看距离以及显示器在驾驶室内的放置高度。人体工程学可定义为应用知识创造一个安全、舒适且高效的工作环境。因此，在设计导航显示器或在拖拉机驾驶室内放置显示器时考虑人体工程学至关重要。如果不考虑人体工程学，人机系统的效率就不太可能得到优化。
