Globalisation and an increasingly multidisciplinary collaboration drive the need for efficient ways to collaborate within distant teams. Although existing computer-supported cooperative work (CSCW) systems, such as collaborative video-conferencing and shared desktops, are suitable for certain tasks, most of these systems have two major deficiencies. First they support the situation of face to face meetings poorly. With a few exceptions, they use a desktop metaphor and this metaphor loses many of the subtleties of interpersonal communication since this does not model or represent the spatial relationships of the participants. Second, again because of the imposition of a desktop metaphor, many systems deal badly with data sets and workspaces that are inherently 3D in nature. What is missing is the ability to naturally gesture towards and manipulate the objects of discussion, and to observe the body language of the collaborators in the spatial context that it is responsive to. Thus, we lose subtle gestures such as gaze being drawn to an object of common interest, or gaze being used by a speaker to indicate whom they want to speak next as they finish speaking. This article serves two purposes. Firstly, it outlines the requirements for a class of CSCW tools that would focus on supporting closely coupled collaborative activity around shared

“…Most collaboration tools use a user event interaction framework (De Oliveira, Hosseini, Shirmohammadi, Malric, El Saddik & Georganas, 2003). However, this approach cannot be applied to VLs because some events may happen without an user interaction.…”

Web-based learning environments are becoming increasingly popular in higher education. One of the most important web learning resources is the virtual laboratory (VL), which gives students an easy way for training and learning through the Internet. Moreover, on-line collaborative communication represents a practical method to transmit the knowledge and experience from the teacher to students overcoming physical distance and isolation. Considering these facts, the authors of this document have developed a new dynamic collaborative e-learning system which combines the main advantages of virtual laboratories and collaborative learning practices. In this system, the virtual laboratories are based on Java applets which have embedded simulations developed in Easy Java Simulations (EJS), an open-source tool for teachers who do not need complex programming skills. The collaborative e-learning is based on a real-time synchronized communication among these Java applets. Therefore, this original approach provides a new tool which integrates virtual laboratories inside a synchronous collaborative e-learning framework. This paper describes the main features of this system and its successful application in a distance education environment among different universities from Spain.

“…Hence it essentially means that the CLE system must be based on the IEEE learning object metadata notion as well as to be based on CB technology. In this direction only very few research attempts can be cited in the literature which address CLE as CB reusable systems (e.g., multibook CLE of the Technical University of Darmstadt (El Saddik et al, 2000), the WebDAV-Collaborative Desk of the Institute of Telematics (Qu et al, 2000) and JASMINE (Shirmohammadi et al, 2003) as well as the Java Multimedia Telecollaboration Kits (Oliveira et al, 2003) from Ottawa University. Indeed the late mentioned research tried to solve many issues related to CLE design flexibility based on CB technology and metadata standardization, but the issue that remain to be answered is how to model their basic visualization objects (i.e., active/flexible and virtual scenes) and how to structure their accompanying metadata.…”

Virtual SceneBean: a Learning Object Model for Collaborative Virtual Learning Environment

It is commonly agreed that a well-balanced mix of collaboration, training and simulation eventually produce a superior learner. Today's collaborative design and learning environments integrate variety of interactive objects as well as many technological aspects to achieve such balance. Unfortunately, the actual profit of the resulting learning systems is largely reduced by poorly represented interactive objects as well as poor interlinking between such objects. In particular, such objects appear isolated: they neither can be modified sufficiently (e.g., by choosing parameters or enhancing functionality) nor be interlinked properly with their context (e.g., by synchronizing with a guided tour or metadata). We are presenting in this article a model for representing virtual and 3D scenes as learning objects. The model utilizes notions and techniques based on Scene Graphs, X3D, Java3D, and SceneBeans. The prototype accompanied with a simple client-server protocol for exchanging and viewing the 3D SceneBeans. This research aims to extend this protocol by utilizing Sun JXTA primitives to link to the POOL of other learning objects repositories.
