Starting from the two touchpoints of physical touchpoint and information touchpoint in college students online learning, the situation of college students attention deficit disorder in touchpoint scenes is collected by means of questionnaire survey, and factor analysis is used to process and analyse the data. It is found that besides negative effects, attention deficit disorder can also bring some positive effects. The reasons for attention deficit disorder are summarized into four points: students lack of interest in classroom content, poor learning environment and learning habits, exploration of platform functions and teacher-student interaction, and social activities. The first two are negatively correlated with learning effects, while the latter two are positively correlated, which can promote learning.
