Nowadays, more Virtual Environments (VEs) are becoming available on the Web. This means that VEs are becoming accessible to a larger and more diverse audience. It also means that it is more likely that the use of these VEs (i.e. how to interact with the virtual environment and the meanings of the associated virtual objects) may be different for different(More)
Cloud computing has leveraged new software development and provisioning approaches by changing the way computing, storage and networking resources are purchased and consumed. The variety of cloud offerings on both technical and business level has considerably advanced the development process and established new business models and value chains for(More)
Increased bandwidth, cheaper and faster hardware, dedicated technology and the success of e-commerce make VR-shops feasible. VR-shops are similar to the e-shops currently available on the Web, with this difference that the products are visualized as 3D objects in a virtual world. Although VR-shops do not require sophisticated VR technology, they should be(More)
Today, the development of a VR application is still a long and difficult task. You need to be skilled in Virtual Reality (VR) technology to be able to develop a Virtual World. There are several technologies like VRML, Java 3D and X3D available to create 3D for the World Wide Web. To be able to develop a Virtual World for the Web, one needs to know how to(More)
Today, the development of a VR application is still a long and difficult task as new features are being developed for Virtual Reality. There is a need to have better modelling tools which will help the designer to model the VR application much more from the domain expert point of view by involving him more in the design process. In this paper, a new(More)
This paper explores the opportunities and challenges for Conceptual Modeling in the domain of Virtual Reality (VR). VR applications are becoming more feasible due to better and faster hardware, and due to new technology and faster network connections they also start to appear on the Internet. However, the development of such applications is still a(More)
Designing and building Virtual Environments is not an easy task, especially when it comes to specifying object behavior where either knowledge about animation techniques or programming skills are required. With our approach, VR-WISE, we try to facilitate the design of VEs and make this more accessible to novice users. In this paper, we present how behavior(More)
Virtual Reality (VR) is gaining in popularity and its added value for learning is being recognized. However, its richness in representation and manipulation possibilities may also become one of its weaknesses, as some learners may be overwhelmed and be easily lost in a virtual world. Therefore, being able to dynamically adapt the virtual world to the(More)
