Research of target identification based on cognitive characteristic

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°.
