多媒体投影教学课件设计的文字-背景颜色匹配研究

Research on combination of letter and background color in courseware design for multi-media projector teaching

该项研究用主观评价方法,在日光灯照明的多媒体投影教学教室条件下,从448种文字-背景颜色匹配中,探索出适合投影系统的最佳投影用文字-背景颜色匹配60种,并且探明投影银幕上的颜色视觉清楚度与前景色和背景色的亮度、对比度(亮度差)以及色调有关。因而建议,在设计投影教学课件时,应选用低亮度的文字颜色与高亮度的背景色匹配,或选用高亮度文字颜色与低亮度的背景色匹配,同时应避免使用低对比度的颜色匹配或同色调颜色匹配。

In this study,448 combinations of letter and background color were compared each other in subjective evaluation method in the condition of multiple media projection teaching classroom under illumination of fluorescent lamp.60 best combinations of color letter and color background were found.It indicates that letter clarity is related to color,luminance,luminance contrast,hue,etc.Moreover,it suggests that the combination of higher luminance letter and lower luminance color background or of lower luminance color letter and higher luminance color background should be used in courseware design for multi-media projection teaching.And the combinations of lower luminance contrast or of the same hue should not be used in the design.
