User similarity provision method

摘要

A user similarity provision method for providing mobile communication devices with information about common interests among first and second users of the mobile communication devices is described. The current position of each mobile communication device are periodically acquired in association with the current time and accumulated as a visited location history. The visited location history consists of location visited records each of which consists of a visited location and a visit time. Similar visited location records are extracted from the visited location histories of the first and second users to indicate common interests shared by them. The similar visited location records are then displayed on the mobile communication devices.

1. A user similarity provision method of providing information about similarities between first and second users who are using first and second mobile communication devices and enabling the first and second users to communicate with each other, each of the first and second mobile communication devices is capable of detecting a current location thereof as a visited location, said method comprising the steps of:
periodically acquiring a current position of the first mobile communication device in association with a current time and accumulating a first visited location history of the first mobile communication device on the basis of the acquired current position and time, wherein the first visited location history consists of a plurality of visited location records, and each of the plurality visited location record consists of a visited location and a visit time; periodically acquiring a current position of the second mobile communication device in association with a current time and accumulating a second visited location history of the second mobile communication device on the basis of the acquired current position and time, wherein the second visited location history consists of a plurality of visited location records, and each visited location record consists of a visited location and a visit time; extracting similar visited location records from the first visited location history, wherein each of the similar visited location records satisfies a predetermined similarity relationship with at least one of the plurality of visited location records of the second visited location history, the predetermined similarity relationship indicating similarity between at least one of the plurality of visited location records by comparing the first and second visited location histories; displaying the similar visited location records on the second mobile communication device as the mutual similarities on the basis of the similar visited location records extracted by the extracting step for providing the second user with one or more interests of the first user that are shared between the first and second users; and displaying an interface on the second mobile communication device for enabling the second user to send a message to the first user and make contact with the first user.
