基于认知特性的目标辨认研究

Research of target identification based on cognitive characteristic

为了优化飞机人机界面的设计 ,结合人的认知特性对目标 (文字或标识 )的形状、大小、辨认反应时间等进行设定 ,并通过二维目标的识别实验进行分析与验证 .实验结果表明对目标大小和反应时间的定量处理比较合理 ,目标形状对目标辨认的影响与以往的研究结果相近 ,在偏离中心视 1 0°范围内 。

To optimize the design of plane's human-machine interface, assume the shape, size and responding time of target(character or mark) according to human cognitive characteristic, and analyse and validate it by two-dimension target identification experiment. The result of experiment suggests that the quantification of the target size and responding time is reasonable, the target shape influences target identification as well as the former research and the target position and color have little effect on target identification within the range departuring from center vision less than 10°.
