The conference system (KS) comprises at least two mobile terminals (M1, M2, M3) with a respective signalling apparatus which contains a sensor which detects motion by the signalling apparatus and outputs a corresponding motion signal. In addition, it contains a motion signal processing apparatus which associates the motion signal from a gesture in nonverbal interhuman communication with a motion signal pattern and, as a result of an association having been made, produces an output signal with a corresponding piece of information about the type of detected gesture in the nonverbal interhuman communication. Furthermore, the conference system (KS) contains a transmission apparatus for supplying the output signal to a transmission channel (F1, F2, F3) which is respectively connected to a local area network (LAN). The latter has a telephone, preferably an IP telephone (11), for a moderator and also a screen (U1) for conference control connected to it. Furthermore, an associated signalling method is proposed.
