Domain-specific modeling (DSM) assists in the creation of visual modeling environments that match the intentions and abstractions of a specific class of end-users. As stepwise refinement is applied, the models may undergo a series of structural and behavioral transformations. The Embedded Constraint Language (ECL) is a textual language for describing transformations on visual models. In a manne...

We discuss the generation of structured visual editors for formally speciied languages. We use the term structured visual editor to refer to a structure{oriented editor which provides language speciic behavior and supports the interactive construction of programs. This paper describes how such a visual editor can be generated from a formal language speciication including the language's visual s...

Brief review is provided of recent research on the impact of early visual language exposure on a variety of developmental outcomes, including literacy, cognition, and social adjustment. This body of work points to the great importance of giving young deaf children early exposure to a visual language as a critical precursor to the acquisition of literacy. Four analyses of data from the Visual La...

GENGED is a generic graphical editor supporting the graphical definition of visual languages. Given an alphabet and rules of a specific visual language GENGED generates a syntax-directed graphical editor for this language. GENGED as well as each visual language defined using GENGED is based on algebraic graph grammars. A sentence is given by a graphical structure consisting of a logical (abstra...

As the user base of visualization solutions expands, it is now even more critical to help end-users visualize their data quickly and effectively. Current automated visualization techniques use only a small set of basic guidelines mostly based on perceptual principles. Yet, visualization design principles and guidelines, as discussed in literature, cover a broad spectrum of factors that guide ef...

Language and vision are highly interactive. Here we show that people activate language when they perceive the visual world, and that this language information impacts how speakers of different languages focus their attention. For example, when searching for an item (e.g., clock) in the same visual display, English and Spanish speakers look at different objects. Whereas English speakers searchin...

Evidence from infant studies indicates that language learning can be facilitated by multimodal cues. We extended this observation to adult language learning by studying the effects of simultaneous visual cues (nonassociated object images) on speech segmentation performance. Our results indicate that segmentation of new words from a continuous speech stream is facilitated by simultaneous visual ...

This article introduces and discusses diierent innovative means for visual speciication and animation of complex concurrent systems. We introduce the completely visual programming language Pictorial Janus (PJ) and its application in the customer-oriented design process. PJ implements a completely visual programming language with inherent animation facilities. We outline the transformation of pu...
