Shared experience information construction system

摘要

In an information terminal processing device of a first user, after selection of a content on a prescribed experience by the first user, content identification information is output to an information terminal device of a second user B, and various information thereof is transmitted to a server device. In an information terminal device of a second user B, after the content identification information is input, a unique key corresponding to the content identification information is generated. Information on the input date and time and/or the input location of the content identification information is transmitted to the server device. In the server device, after collating unique keys, the input date and time and/or the input location of the content identification information are defined as a shared date and time and/or a shared location of the content, and the shared experience information is constructed to make a database thereof.
