Study On Visual Comfort Of Color In Bathroom Space Based On Eye-Tracking Technology

Today’s society is under increasing pressure,the comfort of the living space has become an important criterion for measuring a good or bad residential environment.The importance of the bathroom space as a unit space with high frequency of use,functional concentration and large span of people in family life is obvious.Color as an indispensable component of space design,the impact on the visual comfort of users is crucial.This paper is oriented to improve the human living environment,to enhance the visual comfort of bathroom space as the purpose,through a combination of theoretical analysis and experimental research,put forward a better bathroom space color attributes with the optimal design and improvement of bathroom space to provide theoretical and experimental reference.We firstly sort out the relevant theories of color,analyze the relationship between color and space,and summarize the main factors affecting the color of bathroom space nowadays.Combined with the influence elements of visual comfort,the mapping relationship between color and visual comfort is established.Analyze the current situation of eye-tracking technology in the study of color visual comfort,and determine the key physiological indicators for experimental acquisition: AOI gaze duration,pupil diameter,blink frequency.With the same bathroom space layout as the background,physiological experiments and subjective evaluations of different color attribute matching were conducted to explore the changes of users’ visual comfort.Eye movement analysis results found that in the bathroom space color:(1)when the color attributes are medium brightness-medium saturation-warm tones,the highest visual comfort;when the color attributes are high brightness-high saturation-cool tones,the lowest visual comfort.(2)There are gender differences in the visual comfort of different attributes of the bathroom space color,in the three hues of the environment,the difference in the visual comfort of men is obvious,women in addition to the highest visual comfort in the warm hues of the environment,in the other two hues of the environment,there is no significant difference in comfort.(3)Both males and females are very sensitive to changes in saturation,with significant differences in pupil diameter.(4)Men were more concerned about the changes of saturation and hue,and the gaze duration was significantly higher than that of women.In the subjective evaluation,the color attribute combination with the highest score was medium luminance-medium saturation-warm hue,i.e.,the color attribute combination with the highest visual comfort,which is consistent with the findings of the eye-movement experiment.The findings of this paper help designers understand how users feel about different attributes of bathroom space colors,and have practical guidance for designers to optimize bathroom space color design,helping designers to exclude the worst color attribute combinations and improve efficiency.
