Laser pointer for campus teaching based on cloud server

Abstract

The invention discloses a laser pointer for campus teaching based on a cloud server. The invention belongs to the technical field of teaching appliances. The laser pointer for campus teaching based ona cloud server comprises a pointer body, and a laser emitter is fixedly mounted at the front end of a pointer main body through an electric telescopic rod. The laser emitter with the electric telescopic rod is arranged on the pointer main body, and the electric telescopic rod is used for prolonging the length of the laser pointer, so pointer pointing is convenient, the laser emitter is used for laser pointing to an external projector and highlights key points of a brief report, meanwhile, a retractable handwriting display screen is arranged on the pointer main body, a teacher can mark contenton an electronic display screen and synchronize the handwriting display screen with courseware content of the projector, therefore, teaching content can be enriched easily, the teacher can walk at any place in a classroom to give a lesson, interaction between the teacher and students is effectively improved, and the teacher does not need to give a lesson only by means of the projector.

Problems solved by technology

[0003] Although the existing laser pointer has a single function, it only plays the role of turning pages and laser pointers when it cooperates with computers and projectors. When teachers are teaching PTT, they usually explain by the podium. If the teacher walks to the end of the classroom When it is difficult to use laser marking more accurately, teachers generally just stand at the front of the classroom, which is inconvenient for teachers to walk anywhere in the classroom to give lectures, resulting in less interaction between teachers and students; in addition, the PTT The courseware content is often only used for display, and it is difficult to mark the courseware content or add new explanation content through the laser pointer, and after the next page is flipped through the laser point, the circle point of the page is difficult to save, and it cannot be carried out well.
