Non-verbal behaviour, particularly gaze direction, plays a crucial function in regulating conversations and providing critical social information. In the current set of studies, we represented interactants in a shared immersive virtual environment. Interactants sat in physically remote rooms, entered a common virtual room and played games of 20 questions. The interactants were represented by on...

Nonverbal behavior, particularly gaze direction, plays a crucial function in regulating conversations and providing critical social information. In the current set of studies, we represented interactants in a shared immersive virtual environment (IVE). Interactants sat in physically remote rooms, entered a common virtual room and played games of 20 questions. The interactants were represented b...

This study aimed to investigate the application of Group Dynamic Assessment (GDA) to writing accuracy of EFL learners and explore whether secondary interactants could benefit from interactions between mediator and primary interactants. The idea of implementing DA (Dynamic Assessment) in dyads seems unworkable since teachers are required to teach the whole class (Guk & Kellog, 2007). Moreover, L...

Immersive collaborative virtual environments (CVEs) are simulations in which geographically separated individuals interact in a shared, three-dimensional, digital space using immersive virtual environment technology. Unlike videoconference technology, which transmits direct video streams, immersive CVEs accurately track movements of interactants and render them nearly simultaneously (i.e., in r...

Emotions are the central part of our lives and we display our emotions toward different members of the society to manage and modify it depending on social circumstances. The present investigation wants to study the patterns of emotional displays in visually challenged and normal individuals (studying in IX & X classes) toward different target interactants in two different settings/contexts. Dis...

Recent studies have shown that virtual humans can facilitate social interactions among people who have difficulty in forming social bonds or help develop their social skills by interaction with virtual practice. Virtual human research tends to focus exclusively on appearance or behavior in assessing agent effectiveness, whereas other studies of human social interaction emphasize aspects of the ...

Compared to more common media of communication such as telephone or e−mail, video conferences (VCs) provide further communicational resources for the interactants by allowing for visual cues that are suspected to play a major role in discourse management, cognitive and affective processing. Video−conferencing furthermore has a number of practical advantages compared to real meetings, such as th...

In this paper, we describe a plan-based model for the treatment of misunderstandings in NL cooperative dialogue: an utterance is considered coherent if it is related to some of the interactants' intentions by a relation of goal adherence, goal adoption or plan continuation. If none of them is fully satissed, a misunderstanding is hypothesized and the goal of realigning the interactants' interpr...
