Interactive electronic whiteboard is actually an external device of a computer. The whiteboard itself is equivalent to a computer monitor, which can be touched by hand and operated by multiple touch points simultaneously. When used, it requires the cooperation of the computer, electronic whiteboard, and projector. Before using an interactive electronic whiteboard, you need to connect to a computer, and then project the computer desktop onto the electronic whiteboard surface using a projector. Connect the computer and the electronic whiteboard (via a USB cable), and then position the computer desktop and the electronic whiteboard surface once in the connection program. You can operate the computer manually on the electronic whiteboard, and also annotate, modify, edit, save, and other operations on opened courseware.
