Context-awareness is increasingly becoming an important capability in devices for ubiquitous computing environments. These devices use on-board sensors and history of user interaction to collect data that are used to adapt their behavior to suit with the current environment. There is a need to support real-time software in ubiquitous computing environments, especially in reactive systems, such as distributed and mobile sensors, location-based information service, etc. In these cases, both behavior and interaction among devices depend on constantly changing environmental conditions, in addition to explicit user control. This characteristic requires specific system services to support the development and the runtime operation of real-time context-aware software. This implies that the underlying services must themselves be context-sensitive. The paper analysis current Web-3D visualization technique, based on context-sensitive middleware, and uses B/S internet mode and HTTP transmitting protocol to realize development of Web-3D visualization.
