Evaluation of semi-autonomous agricultural vehicles from a human factors perspective

点击翻译按钮获取中文摘要

Agricultural guidance systems have changed dramatically over a short period. Only two decades ago, there were no sophisticated navigation systems available commercially. In recent years, there have been numerous devices based on global positioning system (GPS) technology beginning with "lightbar" navigation aids (that displayed supplemental navigation information for the driver). Currently, auto-steer systems (that make steering corrections for the driver) are becoming common on Canadian farms. It seems to be inevitable that increasingly-sophisticated navigation devices will be available to farmers. The current trend is towards semi-autonomous and autonomous agricultural vehicles. This rapid change in technology has changed the role to be played by the operator of an agricultural vehicle. Human factors principles are needed to understand how to best utilize the capabilities of the human operator in these new human-machine systems.
