A Service-Oriented Framework for Hybrid Immersive Web Applications

Immersive Web (IW for short) applications such as Second Life and SimCity are increasingly popular among individual users and companies. However, it is difficult to build a hybrid Immersive Web application, because of the different architectures used for building such IW applications. In this paper, we propose a service-oriented framework to support the mashup of heterogeneous IW applications for hybrid IW applications. We first model each object in IW (e.g., a virtual album or a virtual room) as an IW Object Service (IWOS) located by a unique URL with standardized service interfaces. As such, one IW application can use an IWOS instance in another IW application. Moreover, non-IW applications (e.g., an online album system) can also access an IWOS instance via its service interface. We further propose a service-oriented framework to manipulate these IWOS instances, to support the transition of these objects mainly between different IW applications, and to enable the transition between IW applications and non-IW applications. Our framework also includes the fundamental services to build hybrid IW applications. Finally, we provide examples to demonstrate the advantages of our framework, and conduct a qualitative analysis to show the effectiveness.

3D Virtual Client Center and its Service Oriented Modeling

Client centers have considerable influence to the success of a business. Companies encourage people to visit their client centers, in the hope of engaging potential clients. However, this could give rise to large financial costs. With the recent advances in the technology of computer graphics and virtual reality, this paper presents an approach to construct 3D virtual client centers. To visit a virtual client center, the client no longer needs to travel from place to place, but just takes a virtual tour while staying before an internet-enabled computer. The contributions of this paper are as following: 1) we present an approach to construct a 3D virtual client center in a relatively convenient way, 2) we model the virtual client center as a collection of services, to further facilitate the development work.

A virtual-learning service platform and its API based programming learning and design refinement

The evolution of 3D internet technologies has opened a whole new range of opportunities for enhanced learning, and has offered new support in programming learning fields. In this paper, we present a framework for the virtual-learning service platform over 3D virtual worlds. Our framework provides a set of fundamental services that can effectively help to reduce the learning curve in learning programming on a new specific platform and improve the targeted platform development work. The proposed framework is a generalization of our experience gained in developing of a fully immersive 3D e-Iearning system which has been tested and used for customer training.
