How does a digital board work?

Smart Blackboard uses resistive technology to work, which means there is a small air gap between the two pieces of resistive material inside the SMARTBoard. When the user presses the board with a pen or finger, the contact point is registered, and its coordinates correspond to the same area on the computer screen.
"Interactive Blackboard" is an interactive teaching product that uses global intelligent nano touch technology. All In One Smartboard can realize seamless switching between traditional teaching Blackboard and smart Wall Mount Touch Screen blackboard through touch. Can carry out synchronous superposition interaction of teaching content, Mac Screen Sharing. The traditional teaching blackboard is turned into a perceptible interactive blackboard, which has achieved an innovative breakthrough in interactive teaching.
