In this paper, the participants' interaction input emotion is assessed to analyze the current student interaction relationship, and two influencing factors, friendliness and empathy, are extracted. Secondly, the psychological game process of interpersonal interaction is simulated to model the emotion generation process of participants and students, and the sub-game perfect equilibrium strategy of the embedded game is used as the optimal emotion selection strategy. Finally, the student’s emotional states are updated according to the optimal emotional strategy, and the spatial coordinates of students’ emotional states after being stimulated by emotions are labeled with the spatial coordinates of six basic emotions. The results show that the happiness enhancement strategy based on the game model increases from 0 to 0.9, and the effectiveness increases to 1.0.
