Embodiment Construction

[0025] figure 1 It is a system diagram of the interactive electronic whiteboard. Wherein 11 represents a computer, which has a display, 12 represents a projector, which is connected to the computer 11 through a communication link 15, and the projector is generally fixed on the ceiling or placed in a fixed position; 13 represents a positioning pen, which is used by the presenter The positioning pen 13 touches the electronic whiteboard 14, and the electronic whiteboard 14 is generally fixed on the wall, and it is connected with the computer through the communication link 16. The demonstrator uses the positioning pen to touch the electronic whiteboard, and the electronic whiteboard senses the position touched by the positioning pen. The position information is sent back to the computer, and the computer converts the position information into cursor information, and then displays the image on the electronic screen through the projector; the image on the computer monitor is consist...
