Methods for operating interactive whiteboards and apparatuses using the same

An apparatus for operating interactive whiteboards, comprising:

• an interactive display device, providing a connected-device display region, a multi-screen layout region and a whiteboard display region, wherein the whiteboard display region is segmented into a plurality of second blocks and each first block is identical to one second block;
• a communications interface;
• and
• a processing unit, coupled to the interactive display device and the communications interface, and after detecting that an icon of the connected-device display region is dragged and dropped into one first block of the multi-screen layout region, obtaining a network address associated with the icon;
• obtaining a first TCP (Transmission Control Protocol) port number associated with the first block comprising the dropped icon;
• transmitting a first ready notification comprising the first TCP port number to the network address;
• receiving first screen data with the first TCP port number via the communications interface;
• and displaying the first screen data on the second block of the whiteboard display region, which is associated with the first block comprising the dropped icon.
