Lecture note playing system and method based on gesture control

The embodiment of the invention discloses a lecture note playing system and method based on gesture control, so as to ensure that a lecturer can complete the operation of a lecture without operating a mouse. The system comprises a main control unit and a gesture obtaining unit, wherein the gesture obtaining unit is used for obtaining a gesture action; and the main control unit is used for carrying out corresponding specific operation on the lecture when a gesture action obtained by the gesture obtaining unit is matched with a preset specific gesture action, and the specific gesture action corresponds to the specific operation of the lecture. Therefore, the embodiment of the invention can be used for operating the lecture by mainly recognizing the gesture action of the lecturer according to the gesture action, thus the lecturer does not need to operate the mouse.
