The first is the stability of the smart touch screen. Although the Touch Screen is very convenient and easy to operate, it will cause a lot of trouble if it fails. Therefore, when choosing a touch screen, working stability must be the first and most basic requirement.
Secondly, if the Touch Screen Electronic Whiteboard can recognize handwritten text and images, it will be more in line with people's choices. Because in the process of operation, in addition to touching, people may also write and draw. If they can identify and process this information, this technology will be more convenient to press.
Smart Nano Blackboard is a high-tech electronic teaching device. It uses nano touch technology to control by touch to realize seamless switching between ordinary teaching Blackboard and Intelligent Blackboard. In terms of writing, it can realize the synchronous superposition and interaction of teaching content, which can change the normal teaching blackboard. It becomes a perceivable Interactive Blackboard, realizing an innovative breakthrough in interactive teaching.
