Description

technical field

[0001] The present invention relates to an electronic pen, more specifically, to an electronic pen used for an interactive electronic whiteboard. Background technique

[0002] In recent years, interactive electronic whiteboards using electromagnetic induction technology have appeared. This type of electromagnetic induction interactive electronic whiteboard can detect the position information written by the electronic pen, and can transmit the information to the connected computer. The position information and The computer screen images are integrated and projected onto the interactive electronic whiteboard through the projector, thus forming a complete interactive presentation system. Users can easily use the electronic pen to edit, modify, and mark the contents of the computer screen on the interactive electronic whiteboard, just like using a mouse to directly operate the computer.

[0003] For example, the Chinese patent 02225001.8 "Electromagnetic Electro...
