Computer-aided teaching device

Abstract

The invention discloses a computer-aided teaching device which comprises an electronic whiteboard and an input device, and a camera is arranged at the upper part of the electronic whiteboard. The input device comprises a double-hand sleeve. A sensor and a control bag are arranged on the hand back part of each glove. A first controller is arranged in the control bag; the first controller is connected with the analog-to-digital conversion unit and the Bluetooth transmission module. The Bluetooth transmission module comprises a Bluetooth sending unit and a Bluetooth receiving unit, each sensor isconnected with an amplifying circuit, each amplifying circuit is connected to an analog-digital conversion unit, the analog-digital conversion unit is connected with the input end of a first controller, and the output end of the first controller is connected with the Bluetooth sending unit. A second controller and a Bluetooth receiving unit are arranged in the control box, and the second controller is connected with the Bluetooth receiving unit. And the camera and the second controller are both connected to the PC. According to the invention, the remote control of the electronic whiteboard isrealized, and a teacher can interact with students in a short distance while completing the control of the electronic whiteboard.

Description

technical field [0001] The invention relates to the technical field of computer teaching, in particular to a computer aided teaching device. Background technique [0002] With the rapid development of computer technology, intelligent equipment has penetrated into various fields. Taking the education industry as an example, the current teaching multimedia equipment has changed from projection projectors, digital projectors to digital display screens, and even some advanced colleges have installed Electronic whiteboard; as a teaching multimedia device, it is not only more advanced in function, but also has new changes in use. Now the electronic whiteboard can not only play ppt, pictures, videos, but also do simulation experiments or other functions, and Realize the comprehensive touch screen input and delete freely. [0003] However, the current electronic whiteboard still has shortcomings, such as a large screen but poor touch effect. When playing ppt, pictures and videos, t...

Problems solved by technology

[0003] However, the current electronic whiteboard still has shortcomings, such as a large screen but poor touch effect. When playing ppt, pictures and videos, teachers are required to operate near the electronic whiteboard, because the electronic whiteboard and students are on the opposite side of the teacher, and some students will be blocked during operation. Line of sight, resulting in lack of content; because the operation of electronic equipment requires teachers to be on the electronic whiteboard, they cannot interact with students at a closer distance in the classroom, which reduces the teaching effect, and students may be inattentive when they are curious about electronic equipment

[0004] The Chinese patent with the publication number CN 207249936 discloses a computer-aided teaching device, which realizes classroom teaching through a host computer, a large-screen display and a sound system. During the teaching process, you only need to press the request of the terminal controller on the desk where you are sitting to speak Press the button, the request indicator light of the main controller corresponding to the number of the terminal controller on the host keyboard will flash, press the request indicator light for agreeing to speak, the request indicator light and the corresponding number indicator light on the terminal corresponding indicator board will be always on at the same time, and the auxiliary The microphone is also turned on, and students can answer after seeing their numbered lights on; this device only realizes instant adjustments in voice control; it cannot remotely control the screen display or the controller
