Interactive Context-Aware Modeling of Concept Sketch and Operation

In this paper, we present a framework of modeling concept sketch and sketching interaction based on context-awareness. And an operational model for sketching interface has been developed. This new model can guide and help new sketch-based interface development. From a software engineering point of view, the operational model can be implemented as a basic class with a set of standard operational functions. New applications with different context contents can be easily derived from it and developed further. This framework can support all the tasks that are common across applications, requiring the interface designer to only provide support for the application-specific tasks. This new operational model has been implemented and tested with different context. It is capable of and applicable for modeling various sketching interfaces and applications.
