An intelligent teaching system with AR function

Abstract

The invention belongs to the field of intelligent teaching, the invention particularly relates to an intelligent tutoring system with AR function, including servers and terminals, a tag model correspondence table is arranged in that server, a tag model correspondence table include a tag and a correspondence model, the terminal sends an initial label to the server, the server extracts the corresponding model from the tag model table and sends it to the terminal for display. The terminal comprises a storage module and an acquisition module. The storage module pre-stores a history tag informationtable used for recording the usage of the terminal tag in real time. The terminal judges whether there is history information associated with the initial tag according to the history tag informationtable. If yes, the device sequentially sends the corresponding model to the terminal for display according to the history information; and, if not, the terminal sends the corresponding tag to the server according to the information collected by the collection module. The invention is suitable for classroom teaching.

Description

technical field [0001] The invention belongs to the field of intelligent teaching, and in particular relates to an intelligent teaching system with an AR function. Background technique [0002] How to improve middle school students' mathematical spatial imagination? This is a burning problem. In traditional classroom teaching, teachers usually improve students' mathematical spatial imagination by hand-painting three-dimensional drawings. Whether the three-dimensional drawings are more vivid depends on the teacher's drawing ability. It brings some learning obstacles to some students with poor mathematical space imagination; and, in the process of explaining the three-dimensional diagram, in order to facilitate the explanation, the teacher usually stands sideways on the side of the blackboard.

In traditional classroom teaching, teachers usually improve students' mathematical spatial imagination by hand-painting three-dimensional drawings. Whether the three-dimensional drawings are more vivid depends on the teacher's drawing ability. It brings some learning obstacles to some students with poor mathematical space imagination; and, in the process of explaining the three-dimensional diagram, in order to facilitate the explanation, the teacher usually stands sideways on the side of the blackboard. However, the teacher's body hinders some students The line of sight makes it difficult for students to listen to the class; secondly, the hand-painted three-dimensional map can only be displayed in front of the students from a single angle, making it impossible for students to discover the characteristics of the three-dimensional map from multiple angles

[0003] Teachers also feel deeply that hand-painted three-dimensional pictures cannot be presented in front of students more intuitively, which makes it difficult for teachers to teach and makes it difficult for students to listen to lectures. In order to solve this problem, teachers thought of physical models, which can be more intuitively displayed on the In front of students, it is helpful for students to gradually form a concept of space. However, the physical model teaching method also has shortcomings, specifically: when the teacher needs to explain the physical model split, the physical model does not meet this condition, or the physical model can only It is simply split into standard models and cannot be split at will; moreover, there are several kinds of geometric stereograms, and it is difficult to find all the corresponding physical models. If you make the physical model yourself, the production level of the producer is high and the time cost is high. high

[0004] The distress of teaching difficulties also plagues medical and mechanical teachers. For example, when a medical teacher explains the structure of the heart, or a mechanical teacher explains the internal structure of an engine, the internal structures of the heart and the engine are relatively complicated. If it is simply explained in the form of pictures, it is relatively easy for students to understand the structure and function of each part of the heart or engine, but it is relatively easy to connect the contents of each part, because the heart or engine is only in the form of pictures, which cannot be presented to students more intuitively. If students cannot form models in their minds, it will be very difficult for students to understand these interconnected contents

[0005] If it is explained in the form of a physical model, the engine is large and heavy, and it is difficult to carry. In the process of explaining its internal structure, it is difficult to disassemble the engine, and the engine is expensive, that is, the cost is high
