AI Technical Summary
Existing technologies cannot effectively demonstrate students' problem-solving logic in mathematics teaching, and teachers have difficulty accurately selecting students to answer in lecture halls, while students have difficulty getting in and out of their seats.
The system uses a camera unit and a walking mechanism to capture information from the blackboard. It combines invisible infrared signals and AI graphics comparison to identify students raising their hands to answer questions. The camera unit is moved by the walking mechanism to record the students' answering process and then projected in the middle of the classroom. The camera is fixed with a clamp component to reduce shaking.
It enables a complete demonstration of students' problem-solving logic, allows teachers to accurately select answerers, and eliminates the need for students to stand up to answer questions, thus improving teaching efficiency and presentation effectiveness.

Abstract
Description
Technical Field
[0001] This invention relates to the field of teaching equipment technology, specifically to the implementation method and apparatus of an intelligent mathematics teaching support system. Background Technology
[0002] Multimedia classroom equipment for mathematics teaching typically integrates advanced teaching tools such as multimedia computers, projectors, sound systems, and interactive whiteboards. These devices not only present a rich variety of audiovisual materials but also support real-time interactive operations, greatly enriching the means and forms of mathematics teaching. In the teaching process, especially in university classrooms where lecture halls are generally large, the formulas and other teaching content written on the traditional blackboard or the increasingly common multi-functional blackboard (electronic blackboard) are not easily clearly displayed to students at a distance. Therefore, multimedia methods are often used to input the blackboard content and display it on multimedia teaching aids such as projectors. However, in mathematics teaching, a unique aspect is that while the answer to a mathematical problem is important, the problem-solving approach and logical thinking are equally crucial. Current technology can only display the mathematical calculation process and the answer, failing to fully demonstrate the students' logical thinking. The so-called logical thinking refers to the attempts at various incorrect formulas and the selection of various operational expressions during the problem-solving process. It is not displayed in the final answer, but the process often reflects the student's problem-solving thinking. Therefore, we need a teaching aid that can simultaneously record students' problem-solving thinking. At the same time, due to the large size of lecture halls and the fact that most universities use an elective course system, teachers cannot know the students in the class. When choosing students to answer questions, they often do not know how to accurately select specific people from among many. As a result, they can only choose students who are relatively close to them. In addition, the lecture hall is large, and it is not convenient for students to get from their seats to the podium, especially when there are students on both sides of the classroom.
[0003] Therefore, we propose a method and device for implementing an intelligent mathematics teaching support system. Summary of the Invention
[0004] The purpose of this invention is to provide an implementation device for an intelligent mathematics teaching assistance system, in order to solve the problems mentioned in the background art, such as the camera's field of view being limited due to the camera being fixed behind the teacher by a bracket, and the camera's inability to accurately capture all operational details if the teacher's operation causes a change in the position of the drawing board, thereby affecting the decline in teaching quality.
[0005] To achieve the above objectives, the present invention provides the following technical solution: Implementation methods of intelligent mathematics teaching support systems It includes a first camera unit, which is used to capture all input information on the blackboard, the blackboard including a non-electronic blackboard and an electronic blackboard; A walking mechanism is installed on the top of the classroom. The walking mechanism includes motion units that construct three spatial dimensions (X, Y, and Z). The construction platform of the walking mechanism includes a lead screw platform, a cylinder, and an electric telescopic rod. The intelligent recognition and input unit includes a second camera unit connected to one end of the Y-axis moving platform of the walking mechanism. The camera unit is used to record the student's answering process on the desktop. A voice microphone is provided on one side of the camera unit. The voice microphone is used to record the user's voice and amplify it through an indoor loudspeaker. The display unit includes a classroom multimedia computer and a projection device located in the center of the classroom. The processing unit includes a controller, a logic processing module, and a signal source determination module. The controller includes an invisible infrared transmitter and a wireless signal transmitter; the invisible infrared transmitter is used to emit invisible infrared signals; the wireless signal transmitter is used to send an execution signal to the logic processing module while generating information from the invisible infrared transmitter. The logic processing module is used to collect control signals from the controller and, in combination with AI and image comparison, to determine the student behavior recorded by the second camera unit. The determination includes whether the student raises their hand to answer a question. If the determination is yes, the second camera unit is moved above the student answering the question by controlling the walking mechanism, and the student's answering process is recorded and broadcast. The signal source determination module is set up around the classroom. The signal source determination module includes an infrared receiver that can receive invisible infrared light triggered by the controller. The signal source determination module records the path of the invisible infrared light and feeds it back to the logic processing module.
[0006] Furthermore, the operation logic of the logic processing module also includes dividing the seats into n regions, denoted as ABC..., based on the center of the podium as the base point, and encoding and recording the seats in the regions as A1, A2..., B1, B2...
[0007] Furthermore, the operation logic of the logic processing module also includes widening the path of the invisible infrared light received by the signal source determination module to cover a certain area, overlapping this area with areas A, B, C, ..., and marking the students who raise their hands to answer the question in the overlapping area through AI and graphic comparison. The seat numbers of the students who meet the requirements in this area are then fed back to the indoor multimedia system, allowing users to accurately select the answerers from the feedback seat numbers.
[0008] Compared with the prior art, the beneficial effects of the present invention are: One of the effects of the method of this invention is that the entire process of students solving problems can be completely recorded through the walking mechanism and camera unit, and the students' problem-solving logic can be directly fed back. Secondly, through this system, teachers can more accurately select students to answer questions according to their own ideas, and provide more equitable teaching resources for students sitting in the back row. Finally, the design of this invention allows students to answer questions directly in their seats without having to move around, saving unnecessary trouble during the answering process.
[0009] The purpose of this invention is to provide a more stable recording of video signals and improve the display effect. One end of the clamp assembly is fixedly connected to the display motherboard, and the other end is tightly connected to the camera. The clamp assembly consists of a positioning base, a buffer assembly, a sliding bracket, a rotating base, a telescopic rod, and clamps that work together to adjust the position and angle of the clamp assembly. This ensures that the camera can always accurately capture all the details of the teacher's operation on the drawing board, reduces camera shaking caused by the movement of the drawing board, and allows for quick installation and adjustment, ensuring shooting quality and improving teaching efficiency.
