Abstract: The number of isolated persons who suffer from an inability to seek help from others on their own is increasing, and this has become a social problem. To develop a solution to this problem, this study examines the effectiveness of an outreach agent in guiding and supporting isolated persons to a third place through a multi-agent simulation (MAS) using a social interactive swarm model. From the results of the MAS experiments, as a novel insight, we found that guiding isolated persons to a third place at specific intervals until their mental state calmed down, rather than guiding them to a third place one after another every time an outreach agent found them, was effective in reducing the state of isolation of those who were guided to the third place.
