Abstract: Based on the core analytical framework of narratology theory, this study regards the perception of reading progress in paper books as a "narrative spatiotemporal practice." By deconstructing the symbolic attributes of "cognitive anchors" and the logical mechanisms of "order construction, " it reveals the narrative value of progress perception in reading activities. Through case studies, the research identifies three types of progress perception anchors in paper books and proposes design strategies such as "multi-dimensional interactive spatial anchor coordination, " "emotional immersion rhythmic anchor linkage, " and "multi-media mapping anchor expansion, " providing theoretical foundations and actionable practical approaches for optimizing the design of paper book reading experiences.
