People create collective intelligence and make decisions through discussion, conversation, dialogue and debate in organizations and communities in our daily life. This is an autonomous social behavior naturally performed by people as a multi-agent system. It is an important issue in the modern society how to control such a communication field, to optimize knowledge sharing, decision making and learning process in a group. In this paper, we device a research approach called communication-field mechanism design by grasping the phenomena as a control problem of a human social system. In addition, we introduce some pre-existing communication-field mechanisms, such as Bibliobattle and Parliamentary Debate to clarify the notion of communication-field mechanism. We also clarify the relation with the proximity concept such as collective intelligence mechanism, gamification, and mechanism design.
