Abstract [en]

The aim of the present study is to investigate which communicative functions head nods can have in spoken Swedish. By nod is here meant a vertical down-up movement of the head. To classify the communicative functions of head nods 10 short video-recorded Swedish dialogues were analysed and labeled. The labels used are referred to the different communicative functions that the head nods carry out in the given context. The results show that the most common function carried out by head nods is that of feedback. Beside feedback function, head nods can be produced to signal turn taking, focus and emphasis, to give affirmative responses and to show courtesy. The visual information carried out by head nods in spoken communicative interactions is without doubt extremely important; therefore it should be exploited in the field of human-machine interfaces. This could be done by integrating head nods in the design and development of embodied conversational agents. Thanks to the production of head nods, embodied conversational agents might become more effective and appear more natural during their interactions with human beings.
