  • the conventional technology provides specific information to the third user a certain amount of time before the first and second users actually meet at the destination. Therefore, even if the specific information is provided at that time, if the first and second users' plans change thereafter, the third user may not be able to interact with the first and second users.
  • the above configuration allows the third user to grasp the encounter situation between multiple users.
  • the 23rd user can check the situation in which the first user and the second user actually encounter each other, and therefore may be more motivated to head to the destination to interact with the first user and others.
  • opportunities to go out may be increased not only for elderly people living alone, but also for young people who are socially avoidant (recluses), and the like.
  • the information processing device 52 of this embodiment when the first user and the second user encounter each other, information is automatically sent to the third user, so that the specific operation of the client device can be reduced.
  • the specific operation is, for example, an operation in which either the first user or the second user inputs a message to invite the third user, or an operation to make a phone call. This makes it possible to reduce the burden on the first user and the second user. It also reduces the effort and labor required to explain the current location, etc. to the third user.

Specifically, the history information acquisition unit 5207 transmits an out-of-home history transmission request message to the third client device owned by the identified third user. As a result, the third client device extracts out-of-home history of the third user moving to a place other than his/her home from the history of location information recorded in the third client device, and transmits the out-of-home history to the server 5.
  • the out-of-home history may include the third user's frequency of outings, out-of-home destinations, out-of-home dates and times, means of outing, etc.
  • the out-of-home history may correspond to multiple third users.
  • the destination determination unit 5208 identifies a third user who satisfies a specific condition from among a plurality of third users based on the outing history acquired by the history information acquisition unit 5207, and determines the receiving device owned by the identified third user as the destination of at least one of the first specific information and the second specific information.
  • the destination determination unit 5208 also instructs the information transmission unit 5206 to transmit at least one of the first specific information and the second specific information to the determined destination.
  • the destination determination unit 5208 refers to the outing history of each user and classifies the third users into those who satisfy a specific condition, for example, that the frequency of going out is less than a specific number of times, and those who do not satisfy the specific condition, that is, those who go out more than a specific number of times.
  • the destination determination unit 5208 determines a third user who satisfies a specific condition as a destination for at least one of the first specific information and the second specific information for a certain period of time.
  • the destination determination unit 5208 instructs the information transmission unit 5206 to transmit information to the determined destination (third user).
  • the information transmission unit 5206 transmits the information to the determined destination (third user).
  • users who do not often go out may lose motivation to go out if a lot of video is sent to them, so by only sending video for a certain period of time (i.e., enough to pique their interest), it is possible to effectively encourage them to go out.
  • the destination determination unit 5208 may determine a third client device owned by a third user who satisfies a specific condition that the frequency of going out is equal to or greater than a specific number of times as a destination for at least one of the first specific information and the second specific information for a certain period of time. This allows users who go out frequently to have more opportunities to meet acquaintances.

  • the destination determination unit 5210 determines that the emotions of the third user who satisfies the specific condition are stable, and determines the third client device owned by the third user as the destination of at least one of the first specific information and the second specific information. The destination determination unit 5210 then transmits an instruction to the information transmission unit 5206 to permit the transmission of information to the third user.
  • the transmission destination determination unit 5210 determines that the third user's emotions are unstable and excludes the third client device owned by the third user from the transmission destination of at least one of the first specific information and the second specific information. In this case, the transmission destination determination unit 5210 transmits an instruction to the information transmission unit 5206 to not allow the transmission of information to the third user.
