Description

technical field [0001] The invention relates to a teaching method and system using slides to give lectures, in particular to a teaching method and system based on human body gestures and voice. Background technique [0002] Education is the foundation of a country's sustainable development. Advanced teaching facilities can not only improve the fun of the teaching process, but also greatly reduce the distance between the lecturer and the lecturer, and greatly improve the teaching effect. As a widely used multimedia teaching tool, slides overcome the shortcomings of the traditional blackboard teaching method, allowing teachers to focus more on content explanations rather than blackboard writing.

Problems solved by technology

Using a mouse and keyboard for control means that teachers cannot leave the teaching computer too far away, and teachers have to often move back and forth between the blackboard and the computer, which affects the smoothness and efficiency of teaching, and it is even more difficult to support teachers to interact with students in other areas of the classroom

Although the use of a laser pointer can get rid of the defects of using a keyboard and mouse, it requires teachers to hold special tools at all times, so it still plays a certain role in restricting the teaching effect. Because teachers need to pay attention to operations such as slide show and page change, it is easy for teachers to give up some meaningful body language
