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)
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)
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)
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)
Regardless the growing popularity of Virtual Reality, the design of Virtual Environments remains a complex task that requires skilled people. To overcome this, we have developed the VR-WISE approach that allows specifying a Virtual Environment at a conceptual level, free from any implementation details, allowing stakeholders not familiar with VR-technology(More)
