Problems solved by technology

[0003] However, the current presenter does not have marking functions such as ink and line marking with the mouse, so as to realize the function of the speaker to mark important content
Based on the existing technology, if the speaker needs to mark important content or need to highlight part of the content, he needs to go back to the podium and use the mouse to operate. This method is very inconvenient to use, and the speaker cannot move to any place that can be observed place for projection screen

Embodiment 1

[0043] Such as figure 1 As shown, a teaching system based on a presenter includes a presenter 1, a plurality of positioning modules 2, a wireless receiving module 3 and a control center 5, and the presenter 1 and a plurality of positioning modules 2 are connected to The wireless receiving module 3 is wirelessly connected, and a plurality of the positioning modules 2 are respectively placed on the edge corners of the projection screen, and the wireless receiving module 3 is connected to the control center 5;

[0044] The page presenter 1 is used to generate laser light to be projected on the projection screen; it is also used to generate a page turning control signal and a scribing control signal;

[0045] A plurality of positioning modules 2 are used to mark the edge position of the projection screen, position the presenter 1, and synchronize the position of the presenter 1 with the marking points of the projection screen, and generate a positioning signal and a positioning si...

Embodiment 2

[0063] The first distance measuring unit 14 and the second distance measuring unit 24 are respectively designed to be located inside the presenter 1 and inside the three positioning modules 2; the first distance measuring unit 14 is used to measure the distance between the presenter and the three positioning modules 2 The distance between; the second ranging unit 24 is used to measure the distance between the main positioning module and the slave positioning module; the measured distance value is sent to the computer system through the bluetooth communication interface; wherein, the second ranging unit 24 is from the main positioning module and the ratio RO (RO=RX / RY) of the distance value RX obtained between the positioning module and the distance value RY manually measured when the main positioning module and the secondary positioning module are actually installed can be used to correct the work of the presenter, The correction algorithm for the value of the presenter, the ma...

Embodiment 3

[0079] There are three positioning modules 2, one of which is the main positioning module, which communicates with the USB Bluetooth receiving module, two of which are slave positioning modules, and the second wireless transmitting unit inside the two slave positioning modules does not work; the three positioning modules The setting of the master positioning module and the slave positioning module of the module 2 is completed through its internal master-slave setting switch 23; the three positioning modules 2 are respectively placed on the three corners of the projection screen, and their coordinates are given in a preset manner , its power supply is an independent power supply mode;

[0080] The acceleration sensor 15 is designed inside the presenter 1, and one coordinate direction is consistent with the laser beam. The data obtained by it is processed by the data processing module inside the presenter 1 and finally sent to the computer system for angle conversion;

[0081] T...

Abstract

The invention relates to a teaching system and method based on a laser pointer. The system comprises the laser pointer, a plurality of positioning modules, a wireless receiving module and a control center, wherein the laser pointer and the plurality of positioning modules are wirelessly connected with the wireless receiving module, the plurality of positioning modules are respectively arranged at edge corners of a projection screen, and the wireless receiving module is connected with the control center. Compared with the prior art, the teaching system is simple and convenient to use, and can be used for movably positioning and marking on the projection screen.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a teaching system and method based on a page presenter. Background technique [0002] The PPT page presenter is also called the electronic pointer. The current page presenters on the market usually have both the irradiation function of the laser pointer and the function of turning pages by simply pressing the up and down on the laser pointer. Remotely control the computer or multimedia projection equipment to realize free flipping of slides and free presentation. With the page presenter, the speaker no longer needs to stay in front of the podium to operate the computer, and also saves the trouble of walking back to the podium to change pages. [0003] However, the current presenter does not have marking functions such as ink marking with a mouse, so as to realize the function of the speaker marking important content. Based on the existing technology, if the speaker needs...
