Abstract
The invention introduces a method for operating interactive whiteboards, performed by a processing unit of a control node, which contains at least the following steps. A connected-device display region, a multi-screen layout region and a whiteboard display region are provided on an interactive display device. After detecting that an icon of the connected-device display region is dragged and dropped into a block of the multi-screen layout region, a network address associated with the icon is obtained. A TCP port number associated with the block of the connected-device display region, which contains the dropped icon, is obtained. A ready notification containing the TCP port number is transmitted to the network address. Screen data with the TCP port number is received. The screen data is displayed on a block of the whiteboard display region, which is associated with the block of the connected-device display region.
