“…For example, Chovil [39] found that of the 405 semantic displays by speakers, 60% were to some degree redundant with verbal content, while 40% conveyed information that was not in the accompanying words. Nevertheless, the degree of redundancy remains difficult to judge in an objective and precise way.…”

Abstract. In the present study, selected properties of multimodal instructing acts are discussed. Realisations of the instructing acts extracted from a corpus of task-oriented dialogues are analysed in terms of their syntactic structure, prosodic properties and accompanying gestures. The syntactic structures found in the material are similar to those found in earlier studies on map task dialogues. Deictic vocabulary is more frequent in gesture-supported instructions. The mean relative pitch range is similar to the values obtained for instructions in earlier studies and different from the values for syntactically similar questions. As opposite to verbally ill-formed instructions, the wellformed ones tend to contain at least one gestural stroke. It is shown that the relative range of pitch frequency is higher in the gesture-accompanied instructing acts. It is also noticed that prosody and gesture may play similar roles in utterances.Keywords: task-oriented dialogue, instructing acts, gesture, intonation Multimodal Dialogue Analysis and Dialogue ActsThe aim of the present study is to formulate a preliminary description of multimodal instructing dialogue acts in Polish task-oriented dialogues. The analysis is focused on the intonational features of utterances and hand gestures but it also includes some aspects of syntactic and lexical realisation. This research forms a part of the DiaGest project [1] confessed to the study of gestural, prosodic, grammatical and lexical components of task-oriented dialogues. It is meant as a step towards an applicationoriented holistic, multidisciplinary study of dialogue.The idea of a comprehensive approach to the studies on interpersonal communication, in which all of its relevant aspects would be paid the attention they deserve is not new. However, it gained more influence in the twentieth century with the contributions of great philosophers of language, psycho-and sociolinguistics and other researchers interested both in interpersonal and man-machine communication. Also the impact of technology cannot be overestimated. It created demand for formal models of human behaviour, simultaneously providing means for capturing and analysing it.

“…Nagao and Takeuchi (1994) assert that facial expressions serve two functions; as expressions of emotional states, or as communicative signals. Chovil (1991) said that the primary function of facial displays is to communicate messages and emotion to others as the human face can be seen as an independent channel that conveys emotional and conversational signals encoded as facial displays. Another use for facial display is to help develop better social relations as facial displays are usually directed not at oneself, but at others (Takeuchi and Nagao, 1993).…”

Avatars have become a fundamental part of collaborative virtual environments. They are the visual embodiment of the user and are designed to address key issues in the interaction process between the user and the CVE. Giving avatars expressive abilities has been considered essential in computer human reaction. Having an avatar, which has the ability to express facial expressions, as a part of the computer interface increases human performance. Researches have provided strong evidence that emotions can be effectively portrayed visually in avatars to represent human users in collaborative virtual environments. These include manipulation of facial expressions as they are efficient carriers of emotions. However, avatars have still only limited variations in their emotional expressions to become believable entities.

Prior research into embodied interface agents has found that users like them and ®nd them engaging. However, results on the effectiveness of these interfaces for task completion have been mixed. In this paper, we argue that embodiment can serve an even stronger function if system designers use actual human conversational protocols in the design of the interface. Communicative behaviors such as salutations and farewells, conversational turn-taking with interruptions, and describing objects using hand gestures are examples of protocols that all native speakers of a language already know how to perform and can thus be leveraged in an intelligent interface. We discuss how these protocols are integrated into Rea, an embodied, multi-modal interface agent who acts as a real-estate salesperson, and we show why embodiment is required for their successful implementation. q
