We present a conceptual architecture for adaptive human-computer interface of a PT operation platform based on context-awareness. This architecture will form the basis of design for such an interface. This paper describes components, key technologies, and working principles of the architecture. The critical contents covered context information modeling, processing, relationship establishing between contexts and interface design knowledge by use of adaptive knowledge reasoning, and visualization implementing of adaptive interface with the aid of interface tools technology.

The human machine interface is the most important factor to operate correctly, accurate and high efficiency, especially for vehicle equipment. User's psychology and cognitive features should be considered when we design interface. On the basis of concept model of adaptive operational interface, this paper present a user model first, which includes profile model, mental model and behavior mode, then analysis the relationship between information display and user's reaction by series of cognitive tests, such as the influence of text rendering on the reaction time and accuracy .Finally discuss the detail elements and key technologies on the development of adaptive interface.
