Man-machine interaction system and method based on artificial intelligence

The invention provides a man-machine interaction system and method based on artificial intelligence. The man-machine interaction system comprises a file obtaining module, an instruction determining module, a control module and a projection module. The file acquisition module, the instruction determination module and the projection module are all connected with the control module; the file acquisition module is used for acquiring a file input by a user; the instruction determination module is used for analyzing a user instruction according to the interface tactile information; the control module is used for processing a to-be-arranged file according to the knowledge graph construction instruction to obtain a knowledge graph; and the control module is also used for controlling the projection module to project courseware or a knowledge graph on a curtain according to the projection starting instruction. The knowledge graph constructed through the control module can directly serve as a teaching material or serve
