基于眼动特征的可变信息标志视认性影响研究
Research on the influence of variable information markers on recognition based on eye movement features
摘要
Abstract
In order to supplement the brightness requirements of the variable information signs at the alternation of day and night,and improve the visual recognition effect at the alternation of day and night,the effects of environment illumination and font brightness on the visual recognition of variable information signs were studied.Firstly,through the measured environment illumination and font parameter experiments,the key parameters of the visual impact experiment were obtained.Secondly,the eye movement experiment of visual recognition change information signs was carried out to analyze the effects of font brightness and environment illumination on visual recognition.Finally,the optimal matching function between the optimal font brightness and the environment illumination was established.The results show that under the environment illumination of 200,400,600,800 and 1 000 lx,the optimal display brightness of red font is 170,200,230,260 and 270 cd/m2,the optimal display brightness of yellow font is 185,225,265,305,325 cd/m2,and the optimal display brightness of green font is 200,240,280,320,340 cd/m2,respectively.In the case of achieving the best visual effect,the brightness of the font increases with the increase of environment illumination,and the growth rate gradually decreases.Research result affects the best display brightness of different color fonts under different environment illuminations under different environment illuminations,and provides a basis for the parameters of different color fonts to display brightness under different environmental illumination when the day and night alternation are alternately.It is of great significance to improve the visualization of urban road traffic variable information logo and reduce the accident rate.关键词
