The blackboard can not be replaced by other devices completely during the class, because of its role of interacting. The E-blackboard overcomes several problems of the traditional one, such as the dust of chalk, the potential damage to the teacher, waste of resource and storing of the content. An additional electric pen is used to write and erase words on the blackboard. And there is also a button realizing removal of all the content. A USB interface is provided to copy the content to the mobile memory, so as to review it later.
