The main emphasis is how to represent a multi-thread dialogue model in direct manipulation user interfaces. It is shown that control sequence within dialogues, communication with other dialogues,and some computations for applications can be specified with a syntactic and semantic notation. The attribute grammar specification can be implemented using an attribute grammar interpreter embedded in the runtime structure supporting communication, synchronization, and dialogue execution.展开更多

The model provides multi thread dialogs and the concurrent executing of user interface and application procedures. The forms of class based concurrency possible in the model emphasize the human computer interaction and exploit the concurrency across objects and within an object. Dialog descriptions using extended state transition networks, the automatic extraction of concurrency, the facilities for performing synchronization and communicating, generalization and specification, and the smooth transition from dialog design to programming language implementation are also given in this paper.展开更多
