The physical actions performed by any robot can be used to convey meaning to a user in human-robot interaction. For example, successfully performing an action following a request may be viewed as an acceptance, while performing the wrong action may be construed as a mis-understanding. Even hesitating to perform a requested physical action may be viewed as a signal of non-understanding. Thus, unlike in the more orthodox domain of non-situated dialogue, natural human-robot dialogue must account for physical actions as a natural and effective implicit communication channel.
