Abstract

The invention discloses a PPT playing control method and system based on gesture recognition. According to the PPT playing control method and system, a control instruction for adjusting the PPT playing state is generated according to the number of times of continuous opening and the number of times of continuous closing of hands in a preset time, and an operator can remotely control a PPT conveniently and easily on the premise of not carrying any remote control device.

Description

technical field [0001] The present invention relates to office teaching demonstration control, more specifically, to a PPT playback control method and system based on gesture recognition. Background technique [0002] In the teaching system or conference report system, most of the electronic teaching plans and technical reports produced by PPT (PowerPoint) are still controlled by the original mouse and keyboard. Both the teaching method and the conference report pay attention to the interaction between the operator and the audience. , When the operator stepped off the podium to communicate with the audience, and encountered a situation where the PPT needs to be turned, he had to interrupt the communication with the audience and go back to the podium to turn the PPT page. The wired connection restricts the range of activities of the operator and brings a lot of inconvenience to the actual life and work. [0003] In order to solve the above problems, a hand-held remote contro...
