According to an embodiment of the present invention, an electronic bulletin board system comprises a substrate, a sheet, a glass layer, an electronic pen, and an information processing device. The sheet is formed on the substrate and a pattern is printed thereon to determine location information. The glass layer is formed on the sheet. A size of the substrate is bigger than a size of the glass layer. The electronic pen senses the pattern and extracts the location information on the electronic bulletin board from the sensed pattern. The information processing device receives the location information from the electronic pen and displays a processing result of the received location information on the electronic bulletin board. |
