Smart
Nano Blackboard is a high-tech electronic teaching device. It uses nano touch technology and is controlled by touch to realize seamless switching between ordinary teaching blackboards and intelligent electronic blackboards. In terms of writing, it can realize the simultaneous superposition and interaction of teaching content and change ordinary teaching. The blackboard has become a perceptible
Interactive Blackboard, realizing an innovative breakthrough in interactive teaching.
The first is the capacity of the blackboard area: in order to increase the amount of information, traditional blackboards need to be erased repeatedly with a blackboard eraser, which makes the original information unable to be preserved and the writing time is laborious. Most information is expressed verbally or body language. Although the size of Nano Smart Blackboard is not large, it has computer multimedia, wireless Internet function, information storage function, etc., and the amount of information is greatly expanded.
The second is the use function: the traditional blackboard can only use a series of teaching content such as writing, drawing, and stickers. Although the electronic whiteboard projection is convenient, there are many blurry pictures. Smart Board In Classroom has all the functions beyond ordinary blackboards. It also includes functions such as multimedia projection, wireless Internet access, and face-to-face teaching among multiple people. Touch control is simple and quick.
The third is health and safety: long-term inhalation of chalk dust in classrooms and students is very harmful to health. Moreover, long-term use of electronic whiteboards and touch TVs will also have a great impact on the vision of teachers and students. The use of Intelligent Blackboard reduces the hazards of dust. High-definition display and anti-glare nano glass can be excessively harmful to light and protect eyesight.
