基于视觉注意机制下农机导航显示界面的设计

Design of Navigation Display Interface for Agricultural Machinery Based on Visual Attention Mechanism

目前,我国农业机械正在向自动化、信息化和智能化方向发展,而农业机械导航技术是实现农业机械智能化发展的基础。其中,显示界面是操作人员与导航系统交互的媒介,直接影响操作人员的使用体验,也影响着农业机械的高效、安全运行。为此,针对目前农业机械导航界面可用性差、用户满意程度低等问题,以人的视觉机制为基础,从认知生理学角度探究农机操作人员在田间监控作业过程中的视觉注意机制,进而围绕显示界面的图标、控件、导航、布局、色彩和交互等方面对农机导航显示界面进行设计与优化。最后,通过TOPSISI对系统进行视觉体验度量评价,验证所提出的基于视觉注意机制下农机导航显示界面设计方法的实用性和有效性。

China is a large agricultural country in the world,agriculture is the basis of the national economy,is to promote social progress and national food security guarantee,the development of agricultural machinery and equipment industry to promote the rapid development of agriculture.At present,China's agricultural machinery is developing in the direction of automation,informationization and intelligence,and agricultural machinery navigation technology is the basis for the intelligent development of agricultural machinery,of which the display interface is the medium of interaction between the operator and the navigation system,which directly affects the operator's experience of use and also affects the efficient and safe operation of agricultural machinery.This study addresses the current problems of poor usability and low user satisfaction of agricultural machinery navigation interface.Based on human visual mechanism,the study explores the visual attention mechanism of agricultural machinery operators during field monitoring operations from the perspective of cognitive physiology,and then designs and optimizes the agricultural machinery navigation display interface around icons,controls,navigation,layout,color and interaction of the display interface.Finally,the visual experience metric was evaluated by TOPSISI to verify the practicality and effectiveness of the design method of the agricultural machinery navigation display interface based on visual attention mechanism proposed in this study.The research results can provide design reference for the development of agricultural machinery.
