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)
Today, the design of a Virtual Reality (VR) application is still a specialized and time consuming task. Many techniques and software tools have been created to facilitate the development process. However, they all require considerable knowledge of VR technology. Furthermore, modeling the behaviors of the objects in a Virtual Environment requires programming(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)
Nowadays Cloud Computing is considered as the ideal environment for engineering, hosting and provisioning applications. A continuously increasing set of cloud-based solutions is available to application owners and developers to tailor their applications exploiting the advanced features of this paradigm for elasticity, high availability and performance.(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)
Nowadays, the development of a Virtual Reality (VR) application is still very time-consuming and hard for a non VR-expert. In addition, the VR applications often lack the necessary semantic information to make the VR application more intuitive and more attractive for the end-user. This paper describes a new approach for designing VR applications using(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 the 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 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)
