图书馆照明环境中电子阅读视觉满意度预测模型

基于11个大型公共图书馆和高校图书馆的调研数据，建立多元线性回归方程，探讨客观照明参数与主观评价的关系，建立主观评价视觉满意度与照明参数相关的预测模型。该模型表明，在图书馆开放阅览空间中使用电子阅读媒体阅读时，读者视觉满意度随着水平照度平均值和垂直照度平均值的增加而提高；随着斜面照度平均值减少而增加；随着斜面照度均匀度和垂直照度均匀度的增加而提高。由此可以看出，斜面照度均匀度对视觉满意度的影响较大。

Electronic reading visual satisfaction prediction model in library lighting environment

Based on the survey data of 11 large public libraries and university libraries, the multivariate linear regression equation is established to investigate the relationship between the objective lighting parameters and subjective evaluation, which aims to establish the prediction model of subjective evaluation of visual satisfaction associated with lighting parameters. The model shows that when using the electronic reading media in open reading space of the library, the readers'' visual satisfaction would be improved with the increase of average value of horizontal illumination and vertical illumination, the decrease of the average degree of slope illumination, the increase of the uniformity of oblique illumination and vertical illumination. The results indicate that the uniformity of oblique illumination has a greater impact on visual satisfaction.
