Background technique

At present, schools often use computers, multimedia projectors, etc. for teaching. Compared with traditional teaching tools such as blackboards and chalk, it can improve students' learning efficiency and reduce the teacher's writing burden. However, multimedia teaching devices The courseware needs to be prepared in advance, and it is more troublesome to input in real time during the presentation process, and it is not convenient for the interaction between the teacher and the students. After one page of PPT is finished, it will directly switch to the next one, which makes some slow-thinking students unable to follow. The teacher's rhythm cannot achieve the effect of learning, but the traditional blackboard has this advantage, such as strong variability, convenient for on-the-spot performance, and convenient for students to interact on the stage. If the multimedia projection teaching can be combined with the blackboard, it will greatly improve students' learning ability. In addition, if the surface of the traditional blackboard is damaged, it needs to be replaced with a whole blackboard, which is a waste of resources, and it is usually fixed on the wall, which is inconvenient to move and limited. Therefore, we propose a new interactive blackboard Educational teaching display device.
