Abstract：Lighting luminance distribution is one of the significant factors affecting spatial visual experience,however,the priority evaluation semantics and assessment dimensions corresponding to visual task requirements have not yet been clearly defined.This study analyzes the interactive process of visual search and attention,categorizing visual tasks into visual attention tasks,visual search tasks,and long-duration visual tasks.It corresponds by selecting 30 typical sample images from public spaces to conduct semantic evaluation experiments.Using factor analysis,this study extracts the perceptual evaluation factors of lighting luminance distribution and summarizes the assessment dimensions.Through the IPA method,it establishes a connection between lighting luminance distribution and users'subjective experiences,determining the priority evaluation semantics and assessment dimensions for lighting luminance distribution that respond to visual task requirements.The results provide a basis for the assessment of lightingluminance distribution and lay a theoretical foundation for the quantitative study of the effectiveness of visual perception related to lighting luminance distribution.
