Abstract: This paper aims to address the problem of insufficient integration of user visual attention behaviour modelling and spatial practicality in the design of subway public art spaces. This paper first constructs a cultural semantic labelling system and spatial attribute structure for subway stations based on deep neural networks. Second, it achieves multimodal deep alignment between semantic content and visual images through a contrastive language-image pre-training (CLIP) model. Then, it designs a multi-objective optimisation generation framework. Finally, it introduces a spatial structure adaptive analysis mechanism to achieve deep integration of generated content with the real subway environment. Experimental results show that each cultural category achieved high average scores of 0.9025 and 0.88 in terms of semantic consistency and accuracy of cultural background expression, respectively, indicating that the method performs well in terms of visual guidance effect and actual spatial foothold.

Keywords: visual attention modelling; public art space; deep learning; cultural semantic framework; spatial adaptability analysis.
