The needs of the application domain require that agent-systems be capable of supporting agents that are autonomous, concurrent, communicative and mobile. These systems should therefore be based on models of computation where concurrcncy has been dealt with explicitly. In order to realize the benefits of the agent-methodologies., it is also necessary to maintain a strong conceptual relevance to ...

VEC3D is a language learning and teaching project that promises 3-D immersion, live voice interaction and social context. Building on goal-based instructional design, VEC3D learners embody avatars and meet each other in virtual spaces. VEC3D can be integrated into various educational settings, student needs, paces, styles and research goals. This article summarizes the VEC3D curriculum, system,...

The uptake of mobile phones in the UK has increased exponentially in the past two years, indicating that a wider range of users are now utilising mobile technologies in different contexts than ever before. Still little is known about how mobile technologies are used amongst different populations in specific contexts and this research addresses the context of work use by blue-collar workers with...

Three forms of inductive generalization statistical generalization, variation-based generalization and theory-carried generalization are insufficient concerning case-to-case generalization, which is a form of analogical generalization. The quality of case-to-case generalization needs to be reinforced by setting up explicit analogical argumentation. To evaluate analogical argumentation six crite...

The past few years have seen considerable progress in the deployment of voice-enabled personal assistants, first on smartphones (such as Apple’s Siri) and most recently as standalone devices in people’s homes (such as Amazon’s Alexa). Such ‘intelligent’ communicative agents are distinguished from the previous generation of speech-based systems in that they claim to offer access to services and ...

Screening within the 2nd year of life ( primarily between 12 and 18 months ) is a tool for early detection of the risk of a neurobehavioral developmental disorder and is a chance to change the term prognosis of ASD. The Analysis of the interactions of functional and dysfunctional interactive communicative signals from the very early ages of life, as well as of motor patterns , allows us to capt...

Individuals are active audience members that use Internet-based social media technologies to create and negotiate social action in online spaces. Communicative informatics is the key to constructing, describing or critiquing social media. Communicative informatics is the discovery of the audience, text/image, technology, negotiated place relationships that create symbolic meaning. Four proposit...

We are designing a Conversational Agent that communicates at the same time by speech and expressive face. As we are engaged in face-to-face interaction or in any communicative acts where the visual modality is available along with the acoustic one, multimodal signals are at work. Our communicative acts are performed not only through words, but also through intonation, body posture, hand gesture...
