Abstract：In recent years, the rapid development of large-screen mobile phones has changed people\'s lifestyles. People are more and more popular in reading mobile phones at night. However, copying text reading modes under ordinary environmental conditions can easily cause physical and mental problems for people. At present, the study of mobile phone reading texts at night is very scarce. On the one hand, it is difficult to obtain the user\'s nightly reading related data for analysis due to the limitation of technical conditions. On the other hand, the design of the reading nighttime reading mode of the current APP mostly copies the design of the PC page text. The model makes people pay little attention to the user\'s nighttime reading experience. This study relied on a head-mounted eye tracker, designed for usability testing in a dark environment, acquired eye movement information of users reading texts in a dark environment, and explored and analyzed the behaviors and preferences of users when using mobile phones to read texts at night, thereby exploring suitable The best text size and line spacing settings for reading at night.
