摘要
在工程领域,作业人员通常需要面对刺激分布不均的复杂信息界面,并执行相关的交互任务.作业人员的视觉注意力分配已被证明与任务绩效密切相关,但对于复杂界面中基于不同信息分配策略的多优先级刺激对作业人员的视觉注意力分配及任务绩效间的潜在联系仍亟待研究.对此,本文基于多优先级注意力分配策略实验对作业人员在不同负荷条件下的任务绩效和视觉行为的影响机制展开研究.实验结果表明,差异性的分配策略和信息优先级划分提升了任务绩效表现,不同分配策略和优先级划分条件下的视觉行为存在显著差异,并受脑力负荷的影响.该结论能够为人机交互界面的设计和优化提供参考,从而提高作业人员在任务中的绩效表现.
In the engineering field,operators need to face complex information interfaces with unevenly distributed stimuli and perform related interactive tasks.Visual attention allocation of operators has been proved to be closely related to task performance.However,the potential connection between visual attention allocation by multi-priority stimuli based on different information allocation strategies and task performance in complex interfaces requires further investigation.In this study,task performance and visual behavior of operators under different load conditions are studied on the basis of the experiment of the multi-priority attention allocation strategy.The experimental results indicate that the differential allocation strategy and information priority division improve the task performance,and the visual behavior differs significantly under different allocation strategies and priorities and is affected by mental loads.This conclusion can provide a reference for the design and optimization of human-computer interfaces and thus improve the task performance of operators.
