Teaching blackboard writing display method and device, equipment and computer readable storage medium

Abstract

The invention discloses a teaching blackboard writing display method, which comprises the following steps: collecting and storing a blackboard writing image corresponding to each board of blackboard writing content on a writing board; determining to add a new board of blackboard writing content on the writing board; and displaying the blackboard writing image, the storage time of which is latest, on a display terminal arranged adjacent to the writing board. Correspondingly, the invention discloses a teaching blackboard writing display device, equipment and a computer readable storage medium.

Description

technical field [0001] The invention relates to electronic teaching technology, in particular to a method, device, equipment and computer-readable storage medium for displaying teaching blackboard writing. Background technique [0002] Writing on the blackboard on the electronic whiteboard provided by the touch screen terminal has the advantages of no dust, effortless writing and easy erasure, so the electronic whiteboard is gradually popularized in the teaching classroom. But it cannot replace the traditional blackboard, because the electronic whiteboard cannot restore some details such as strokes, which may lead to poor viewing effect of the saved blackboard writing, especially for some courses that need to restore handwriting details, such as art, calligraphy, etc. Moreover, the interference of auxiliary educational equipment (such as a settable, etc.) cannot be ruled out. For example, when using a settable to measure on a blackboard, the touch screen will misjudge the se...

AI Technical Summary

Problems solved by technology

But it cannot replace the traditional blackboard, because the electronic whiteboard cannot restore some details such as strokes, which may lead to poor viewing effect of the saved blackboard writing, especially for some courses that need to restore handwriting details, such as art, calligraphy, etc.

Moreover, the interference of auxiliary educational equipment (such as a triangle) cannot be ruled out. For example, when using a triangle to measure on a blackboard, the touch screen will misjudge that the triangle is the content of blackboard writing and display it, resulting in redundant content in the final displayed blackboard

[0003] However, traditional writing boards, such as blackboards and whiteboards, have a limited writing area and cannot be restored once erased. Therefore, students need to take notes quickly. If the area is not enough, the lectures will be suspended, which will slow down the teaching progress and affect the quality of education
