Multimodal agent interfaces and system architectures for health and fitness companions

Multimodal conversational spoken dialogues using physical and virtual agents provide a potential interface to motivate and support users in the domain of health and fitness. In this paper we present how such multimodal conversational Companions can be implemented to support their owners in various pervasive and mobile settings. In particular, we focus on different forms of multimodality and system architectures for such interfaces

Mobile Learning Revolution: Implications for Language Pedagogy

Mobile technologies including cell phones and tablets are a pervasive feature of everyday life with potential impact on teaching and learning. “Mobile pedagogy” may seem like a contradiction in terms, since mobile learning often takes place physically beyond the teacher's reach, outside the walls of the classroom. While pedagogy implies careful planning, mobility exposes learners to the unexpected. A thoughtful pedagogical response to this reality involves new conceptualizations of what is to be learned and new activity designs. This approach recognizes that learners may act in more self-determined ways beyond the classroom walls, where online interactions and mobile encounters influence their target language communication needs and interests. The chapter sets out a range of opportunities for out-of-class mobile language learning that give learners an active role and promote communication. It then considers the implications of these developments for language content and curricula and the evolving roles and competences of teachers

Multimodal person recognition for human-vehicle interaction

Next-generation vehicles will undoubtedly feature biometric person recognition as part of an effort to improve the driving experience. Today's technology prevents such systems from operating satisfactorily under adverse conditions. A proposed framework for achieving person recognition successfully combines different biometric modalities, borne out in two case studies

Qualitative and mixed methodology for online language teaching research

This paper provides an overview of CALL (Computer Assisted Language Learning), its history and current developments. It presents a rationale for moving CALL research forward, and outlines a particular approach to researching online language teaching and learning: the use of qualitative methodology. It is in this historical context that a case for more qualitative and integrative research designs is made. Examples of qualitative and mixed method studies are taken from the context of language teaching at the Open University in the United Kingdom, the largest institution of its kind in Europe, with a remit of teaching all subjects at university level to adults, regardless of their prior qualifications. With the help of these examples the scope and promise of qualitative approaches are discussed

Affective Medicine: a review of Affective Computing efforts in Medical Informatics

Background: Affective computing (AC) is concerned with emotional interactions performed with and through computers. It is defined as “computing that relates to, arises from, or deliberately influences emotions”. AC enables investigation and understanding of the relation between human emotions and health as well as application of assistive and useful technologies in the medical domain. Objectives: 1) To review the general state of the art in AC and its applications in medicine, and 2) to establish synergies between the research communities of AC and medical informatics. Methods: Aspects related to the human affective state as a determinant of the human health are discussed, coupled with an illustration of significant AC research and related literature output. Moreover, affective communication channels are described and their range of application fields is explored through illustrative examples. Results: The presented conferences, European research projects and research publications illustrate the recent increase of interest in the AC area by the medical community. Tele-home healthcare, AmI, ubiquitous monitoring, e-learning and virtual communities with emotionally expressive characters for elderly or impaired people are few areas where the potential of AC has been realized and applications have emerged. Conclusions: A number of gaps can potentially be overcome through the synergy of AC and medical informatics. The application of AC technologies parallels the advancement of the existing state of the art and the introduction of new methods. The amount of work and projects reviewed in this paper witness an ambitious and optimistic synergetic future of the affective medicine field

A Review of Verbal and Non-Verbal Human-Robot Interactive Communication

In this paper, an overview of human-robot interactive communication is presented, covering verbal as well as non-verbal aspects of human-robot interaction. Following a historical introduction, and motivation towards fluid human-robot communication, ten desiderata are proposed, which provide an organizational axis both of recent as well as of future research on human-robot communication. Then, the ten desiderata are examined in detail, culminating to a unifying discussion, and a forward-looking conclusion

Gesture in multimodal language learner interaction via videoconferencing on mobile devices

This thesis focuses on how adult English language learners exploit and experience gesture while communicating with one another via mobile technologies. Mobiles create opportunities for multimodal language learning beyond the classroom (Kukulska-Hulme et al., 2017), however, modes such as gesture are mediated and transformed by technology in complex ways (Hampel & Stickler, 2012). In a small-scale qualitative study, learners from a range of nationalities who were studying on language programmes in the UK were connected in dyads via Skype videoconferencing (VC) in order to complete information gap tasks using tablets, 2-in-1 devices, and smartphones. These communicative tasks had been intentionally designed around a diversity of informal ‘settings’ (Benson, 2011) which included cafés, museums, and historical buildings. Following the tasks, participants took part in stimulated recall interviews in order to reflect on their multimodal forms of communication. This exploratory, qualitative study examines gesture from a theoretical perspective which links the mode to spoken language (Kendon, 2004; McNeill, 1992; Norris, 2004) and positions gesture within the wider framework of the negotiation of meaning (Varonis & Gass, 1985). As the role of speech-associated gestures within language learning via technology has not been widely researched, an interdisciplinary methodology had to be designed to analyse the video recorded data from the learners’ tasks. This is based on transcription procedures from gesture-speech analysis (McNeill, 1992; McNeill & Duncan, 2000). As gesture in this study is understood as being closely aligned to speech, a multimodal unit of analysis was combined with the Varonis and Gass (1985) framework of the negotiation of meaning. The multimodal method allowed for the categorisation and analysis of gesture to investigate how learners may co-orchestrate the two modes in relationship to their deployment of mobile technologies from beyond the classroom. The participants were asked to reflect on their interactions from multimodal perspectives and interview data were triangulated with the task performances. Theoretical and pedagogical conclusions are drawn as to the manner in which learners exploit gesture as an integral part of the negotiation of meaning
