I'm not sure I understand your question. The idea for these systems is that the person is used as a wire; and communication is possible only when the person touches the object (or person) that they wish to communicate with. If the system is misdesigned, then it is possible to pick up the signal whether or not the person is touching the other object, so the system behaves more like a wireless radio.
