In the pervasive computing environment, the users interact with the system through various terminals. How to adjust application interface according to the characteristics of terminals is very important in the pervasive computing system. In order to solve the interface diversity of pervasive terminals, an interface adaptive framework based on SVG is proposed. The framework adopts the hierarchical structure of separating interface and processing logic. By constructing the abstraction function mode of application, a uniformly SVG-based terminal interface is generated for different terminals. The simulation result shows that the framework has better practicability.
