Description

technical field [0001] The invention relates to the field of multimedia teaching, in particular to a multimedia circuit system with the function of previewing the next page of ppt. Background technique [0002] Modern teaching mostly uses PPT courseware for teaching. On the one hand, the electronic course teaching plans written by teachers can be permanently saved, and can be modified and updated quickly. With the help of animation, flash, video, audio, etc., the course explanations are more vivid.

Problems solved by technology

For example, many college student competitions require students to use ppt to introduce their works on the podium. Because some students are prone to nervousness on the podium, even if they have prepared before, they will still forget the words when explaining the ppt. This phenomenon will not only delay the speech time, but also affect the game score

When explaining the ppt, sometimes some lines that connect the two ppts are needed, but because many speakers cannot remember the position of each ppt when explaining, when explaining the lines that connect the two ppts, they often use the ppt Turning to the next page and quickly turning back after seeing the content of the next page will dazzle the judges and audience; in addition, sometimes the speaker temporarily needs to display a page in the ppt separately, at this time the speaker needs to Flip through the ppt quickly, and the projector will also display all the operations of the speaker, and it will also give the judges a feeling of dazzling fireworks, which will affect the competition results
