The paper describes a formal model to specify the syntax and semantics of interactive visual languages by SR-task grammars. The proposed approach provides language designers with a new type of grammars based on the formalism of symbol-relation grammars, where a new form of production rules allows to directly specify the interactive behavior of the visual environments described. Therefore, the language designer only has to define the development of a visual scenario depending on occurring events, and the changes of the state of a scene is regarded as the application of a rewriting rule.
