In general, those who are right in front of each other can share actual world events that are generated in the same working space. For example, when an audio or a light of a wave form pattern is generated, by recognizing such an actual world event, both communication apparatuses share the actual world event. Also, a shock wave generated when one communication apparatus is hit with the other is shared by both. One of the communication partners searches a network for a communication partner who is right in front with the actual world event as a clue. Thus, it is possible to perform data communications with a communication partner whose location in the actual world is clear, such as being right in front, but whose identification information in the communication medium is unknown.
