3D Graphics Visualization and Context Information Service for a Virtual Tourist System

In this paper, we present a virtual tourist system with realtime 3D visualization and the assistance of context information service. Our system enables a visitor to take a discovering tour on a virtual environment from a remote client by following navigator or by self-navigating. During the tour, the system provides immersive 3D graphics contents while supporting relevant information to the visitors corresponding to their positions in the virtual environment. When the visitors interact with interested objects, the context information service will also support introduction information for presenting about the objects. The introduction information based on text format is represented by a comfortable way-audio conversion to visitors in different languages depended on their preferences using TTS(Text-To-Speak) tool.
