Embodiment Construction

[0048] as attached figure 1 As shown, the present invention proposes a visual teaching display system, which is composed of an aerial writing subsystem and an electronic chalk subsystem.

[0049] Air writing subsystem consists of teaching pen 1, projection screen 2, filter 3, wireless camera 4, computer 5, and projector 6;

[0050] The electronic chalk subsystem consists of a teaching pen 1, an ultrasonic receiver 7, an ATMega128 single-chip microcomputer chip 8, an APC220 serial communication module 9, a computer 5, and a projector 6.

[0051] The working principle of a visual teaching display system proposed by the present invention is as follows:

[0052] a. Air writing subsystem: the laser emitting end 1a of the teaching pen 1 emits red laser light to the projection screen 2, forming a laser light spot signal on the projection screen 2, and the light spot signal of the projection screen 2 is filtered by the filter 3 to reduce noise Enter the camera lens of wireless camer...

Abstract

The invention discloses a visual teaching display system, which includes a projector, a projection screen, a computer, a teaching pen, a camera, an ultrasonic receiver, and a computing chip. The computer receives the light point image or the position coordinate information of the teaching pen, And process the light point image to obtain the light point coordinate information; call the built-in drawing function according to the light point coordinate information or the teaching pen position coordinate information, generate the corresponding light point coordinate image or the teaching pen position coordinate image, and convert the light point coordinate The image or the position coordinate image of the teaching pen is output to the projector. The invention realizes the fusion of the multimedia teaching mode and the traditional blackboard teaching mode, and the teaching teacher can switch as desired and on demand, effectively improving the classroom efficiency. The invention adopts solar charging mode to supply energy to the core component teaching pen, and realizes long-time battery life of environmental protection. The investment cost of the invention is not high, it is suitable for all kinds of teaching institutions in the country, and has a very good application prospect.

Description

technical field [0001] The invention belongs to the field of information technology teaching, in particular to a visual teaching display system. Background technique [0002] With the popularization and application of information technology, computer-aided multimedia classroom teaching, a new teaching mode, has attracted more and more attention in the teaching circle. Teachers use PPT, WPS and other software to make electronic courseware for lectures (hereinafter referred to as multimedia teaching). Due to the vivid image, large amount of information and various display forms of multimedia teaching, it is deeply loved by teachers. However, in the process of practical application of multimedia teaching, it has exposed its disadvantages compared with traditional blackboard teaching: for example, teachers stand by the computer for a long time, and have little eye and body communication with students; It is difficult for students to digest too fast, and they cannot grasp the k...
