    Although there has been considerable research into ways to design visual programming environments to improve the processes of creating new programs and of understanding existing ones, little attention has been given to helping users of these environments test their programs. This feature would be particularly important for systems aimed at end users, since testing is the primary device they use to... View full abstract»

    Sonnet was designed as a visual language for implementing real-time processes. Early design and development of behavioral components has largely focused on the domain of music programming. However, Sonnet's architecture is well-suited to expressing many kinds of real-time activities. In particular, Sonnet is easily extended with new kinds of data types and behavioral components. We have developed ... View full abstract»

  • Mazes and morphs: modeling meaning in Glide, a non-linear, dynamic visual language

    Publication Year: 1999, Page(s):96 - 103
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (200 KB)

    Glide is a system of visual signs, an artist's exploration of the possibilities of meaning-making in the age of ubiquitous computing. Glide was originally constructed as an artifact in a work of speculative fiction of the same name. Examining the language, both from within the narrative and from a theoretical stance outside the narrative world, has led the artist into a kaleidoscopic maze of sugge... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (284 KB)

    An NCE context-sensitive graph grammar, that is, a context-sensitive graph grammar with neighborhood controlled embedding has been developed. It is an expansion of the well-known NCE (context-free) graph grammar. Because it has a quite general embedding mechanism, it can be used to formalize the graph-syntax rules of visual objects with much flexibility. The composition of its production copies is...

    The visualisation of large hierarchies without losing context is a difficult problem. Many interfaces have been developed for this, and many of these use zooming, which is sometimes combined with a distortion view method such as a fisheye lense. Most of these interfaces use and zoom in two dimensions, while others use and zoom in three dimensions. We present a 2D interface realised in the SGviewer... View full abstract»

    Graph-based notations form a significant subclass of visual languages. Studies of the use of such notations in practice have shown that users often employ pragmatic aspects, such as layout, to capture important domain information. Moreover this pragmatic information can support and guide reasoning over such representations. However, typical formalisations of graph-based notations often pay scant r... View full abstract»
