[Purpose/significance] This study explored the effects of digital navigation and cognitive load on older readers' user experience, and accordingly proposed the optimization suggestions.[Method/process] Extremely controlled experiment method was used in this study, and older readers were invited to attend the reading experiment under different cognitive load conditions. They were asked to fulfill different tasks commonly used in the digital library by different navigation structures of digital libraries.[Result/conclusion] The results showed that the navigation structure has significant influence on usability. In addition, interaction effect between cognitive load and navigation structure were found. Older readers' affects and task efficiency were significantly influenced by the two factors.
