多界面多任务下不同任务权重的目标辨认

武器装备人机界面设计中目标辨认问题,必须通过目标辨认的实验和评价研究加以解决.根据飞行作业中所需完成的操作任务,提出一个多界面多任务目标辨认实验方案.通过测定被试完成实验主任务的反应时间和正确探测率,研究人在不同任务权重下对目标颜色、形状、位置的辨认情况,为人机界面设计目标编码提供科学依据.实验结果表明:在需要分配人注意力的条件下,无论任务权重如何,绿色、红色和三角形是界面设计中合适的目标编码,圆形和正方形必要时可用于目标编码;人对不同位置的目标辨认受到任务权重的影响,人机界面对目标位置的设计要充分考虑任务权重因素.

Target identification of different task weight under multi-interface and multi-task

Target identification for weapon equipment in human machine interface design must to be settled through the research of experiments and assessments. A target identification experiment of multi-interface and multi-task was developed, according to tasks what pilot need to operate during flying. This work investigated how human identify target color, figure and location under different task weight by measuring response time and detection rate what participator react to main task to provide standards for target code in human machine interface design. Result indicates that green, red and triangle are the fit code for target in interface design and square and circular necessarily can be made as the target code under the need of attention allocation, no matter what task weight is; it is indispensable to take task weight into account in designing target location for human interface, as target identification of different location is affected by the task weight.
