The research on smart classroom interaction has received much attention recently. However, the current research methods mainly analyze smart classroom interaction from the time dimension, ignoring the impact of the spatial dimension on classroom interaction, and the vertical depth and mobility of spatial interaction. Based on this, smart classroom interaction is analyzed from the perspective of interaction space, with a focus on the specific application of Interactive Geographic Analysis (IGA) in the analysis of smart classroom interaction. IGA conducts the transcription and slicing analysis of teaching interaction in the physical space and cyberspace of smart classrooms, and presents teachers' and students' interactive movement trajectories and interactive spatial preferences in a dynamic visualization way, which provides scholars at home and abroad with new perspectives for researching smart classroom interaction.
