Abstract
Disclosed is an interactive electronic white board with a large screen. The interactive white board1, which is a projection face, is composed of an electronic writing board5 and a display6. The electronic writing board5 is connected with a computer through a communication module, and the information collected by the electronic writing board5 is processed by software and then is projected onto the interactive white board1 through a projecting camera. The software consists of a selector which conducts key processing, data conversion, drawing and editing, attribute displaying, and a content display module. When a point on the electronic writing board5 is occupied by writing, the signals about the position and the state of the point are transmitted to the computer for conversion and then the signal data are processed according to displaying attribute and operation command so as to convert the white board coordinate into screen coordinate matching with the screen and to convert the state of a point device2 into mouse state to renew the data of the screen; the signals of the screen are projected onto the interactive white board1 through the projecting camera. Therefore the interactive electronic white board solves the problems in writing write on a large screen and broadens the application range of the interactive white board.
