Presence and co-presence in collaborative virtual environments
Presence in Collaborative Virtual Environments (CVEs) can be defined into personal presence and co-presence. Personal presence is having a feeling of "being there" in the CVE yourself. Co-presence is having a feeling that one is in the same place as the other praticipants, and that one is …

Continuum: an architecture for user evolvable collaborative virtual environments
<p>Continuum is a software platform for collaborative virtual environments. Continuum's architecture supplies a world model and defines how to combine object state, behavior code, and resource data into this single shared structure. The system frees distributed users from the constraints of …

An Observation Framework for Recognising Learning Evidence in 3D Collaborative Virtual Environments
Immersive environments such as 3D virtual spaces enable collaborative learning and facilitate better connections between students, virtually. Learners do acquire new knowledge or skills while practising collaborative activities in such spaces. However, recognising evidence of learning to assess …

Mobile Collaborative Virtual Environments: A Paradigm Shift from Desktop to Mobile Online Communities
There are myriad examples of virtual communities and environments available for collaborative activities. However, most of these environments are confined to the desktop and thus preclude collaboration while users are on the move. Through a scenario-based design process, this article establishes …

Virtual reality simulation modeling for tele-surgery and tele-haptic class of applications
The incorporation of Haptic interfaces in Collaborative Virtual Environments (CVE) suffers from setbacks due to an inherent technical problem that occurs when the users are geographically distributed. The main causes of such discrepancies are network delay, a lack of view of individual …

Virtual workplaces : when metaphors breakdown
… As we introduce new technologies and build new environments our model is changing. Today's virtual workplaces are grounded in models of work that have been reformed from our experiences using current technology in physical workspace. However we are discovering opportunities and possibilities for …

Video based reconstruction system for mixed reality environments supporting contextualised non-verbal communication and its study
… the computer generated avatars used in Immersive Collaborative Virtual Environments can be replaced with ones that are faithful of the people they represent and supporting researchers in their study of human communication such as gaze, inter-personal distance and facial expression.The system has …

Collaborative Interaction in Virtual Environments
Collaborative virtual environments (CVEs) extend existing virtual environment (VE) technology to enable it to run over a network (e.g. the Internet), and introduce mechanisms that allow multiple people to co-exist, be aware of each other’s presence (e.g. through avatars) and communicate. CVEs are …

A model for 3D virtual environment for learning based on the detection of collaboration through an autonomous virtual tutor = Modelo para Detectar la Colaboración en un Entorno Virtual 3D para la Mejora de la Enseñanza Basada en un Tutor Virtual Autónomo
… presents a model that, through an autonomous virtual pedagogical agent, can support interaction in the frame of Collaborative Virtual Environments for learning. With the advantage of the visual aspect available in Virtual Environments, specifically the user embodiment, his/her avatar, the …

Supporting Spatial Collaboration: An Investigation of Viewpoint Constraint and Awareness Techniques
… techniques. Phase 3 focuses on three-dimensional virtual environment techniques, comparing similar and different frames of reference. The final phase reuses the favorable techniques from the previous studies and presents a novel prototype that combines both two-dimensional and three-dimensional …
