Mapping server and mapping method

A mapping method comprising:

• storing, in a mapping server, information on terminal call signal displayed on at least one of call areas defined in a portion or an entirety of a display area of a display unit controlled by a display controlling computer identified on a network, the information on terminal call signal includes color sequence information having a plurality of colors changed with passage of time;
• receiving, by the mapping server, response signal from a portable terminal device recognizing the terminal call signal displayed on the display area by the display controlling computer through a photo-sensor installed on the portable terminal device, the response signal includes the color sequence information corresponding to the terminal call signal recognized through the photo-sensor by contacting the portable terminal device with the at least one of the call areas of the display area;
• and
• mapping, in the mapping server, between the information on the terminal call signal and the response signal, thereby linking between the display controlling computer and the portable terminal device on the network so that any one or both of exchanging and sharing of data between the display controlling computer and the portable terminal device are performed.
