  • Abstract In pervasive computing environment, user will use pervasive device to access web content. Currently, using pervasive device access most of web contents presents bad visualized effect, which impeded knowledge sharing. In addition, the great diversity of user's preference, environment, and device increases the difficulty and complexity of content design.
    Therefore, we proposed a context-based adaptation solution, named Context Oriented Content Adaptation Framework (CCAF), that helping user to overcome accessing problems. The proposed framework is started from multimedia content decomposition. Each object is adapted according to specified adaptation rule, which determined from the user’s context. The template composition dynamically produces the corresponding style-sheet. Then an adapted XML-content will show on user’s device. Experiments show that CCAF is an extensible and scalable middleware system providing content adaptation service among heterogeneous context.
