    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»

    We are artists working on the creation of interactive computer systems that use the audiences' participation as essential input for the creation of image structures. In 1998 and 1999 we created two interactive Web sites for the Internet called VERBARIUM and LIFE SPACIES. These two Web sites allow users on the Internet to write text messages that are instantly translated into visual 3D forms. Our c... View full abstract»

    An analysis of how visual modeling of structure and dynamic behavior of a multimedia application differs from modeling conventional software shows that aspects of the graphical user interface and time-dynamic behavior ought to be integral parts of a coherent multimedia application model. In this sense, we extend the model-view-controller paradigm towards multimedia. As a result, we present OMMMA-L... View full abstract»

    This paper describes a browsing system for movie database. The system, named ZASH, was designed and developed to explore the following features: (1) the use of multiple 2D planes to separate different types of information; (2) the use of 3D space to improve the visibility of links between nodes; (3) the use of multi-dimensional scaling to lay out movies and commentators so that the similar data ar...

    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»

    Supporting smooth image transitions is a valuable feature in software visualization systems, but it seems difficult to achieve in declarative frameworks, as they are basically data (and not event) driven. This paper discusses the problem of specifying an animated behavior of graphical objects in a declarative style, addressing both automation and customization possibilities. In particular in our f...

    This paper describes a novel application of enhanced visual programming and visualisation techniques to support data mining processes on the Internet. While the idea of using visual languages to support data mining has been proven to be useful, the usability of existing implementations has been limited Here, we consider the issue of usability of data mining via the Internet.

    Isaac is a rule-based language for mobile robots currently under development at NMSU. A successor to Altaira, it replaces Altaira's state-based rules and tile-based navigation with a more general geometric reasoning mechanism. The language uses the FuzzyCLIPS expert system shell as a reasoning backend View full abstract»

    Scrollbars provide a simple way to traverse an information space, but they provide little data about the actual contents of the space. Of the many visualization techniques that have been proposed, few have maintained the simple functionality of the scrollbar while showing improved performance on typical scrollbar tasks. This paper presents two enhancements to the scrollbar, a mural bar and a pile ... View full abstract»

    In this paper we present an enhanced version of VLCC, a graphical system for the automatic generation of visual programming environments. The enhancement has been obtained by introducing a new syntactic model based on the concepts of hybrid and hierarchical visual languages. The resulting system is able to support the development of complex real world visual languages which occur in the field of s... View full abstract»

    To ease the development of distributed systems, the visual notions for the structural aspects of object-oriented analysis and design should be combined with techniques for handling concurrency and distribution. A novel approach and language for the visual design of distributed software systems is introduced and illustrated by means of an example. The language of OCoNs (Object Coordination Nets) is...

    This paper reports on an experiment which compared small control and data flow visual programming languages (VPLs). The study used a combination of the match-mismatch conjecture and the information types approach in order to investigate the effect of language style on comprehension. Results showed that the control flow VPL is associated with faster task performance, regardless of the match between... View full abstract»

    We present a novel architecture to map the two-dimensional Internet space in virtual worlds according to predefined or inferred metaphors. Web elements and metaphor elements are both conceptualized as semantic-networks and are compared through an inference engine in order to detect similarities. Once all the web elements have been mapped within a virtual world metaphor, a VR-Builder generates VRML... View full abstract»

  • An NCE context-sensitive graph grammar for visual design languages

    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...

  • Visual specification of spatio-temporal developments

    Publication Year: 1999, Page(s):187 - 188
    Cited by:  Papers (4)
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (20 KB)

    We introduce a visual language for the specification of temporally changing spatial situations. The main idea is to represent spatio-temporal (ST) objects in a two-dimensional way by their trace. The intersections of these traces with other objects are interpreted and translated into sequences of spatial and spatio-temporal predicates, called developments, that can then be used, for example, to qu...

    We refine our design methodology for visual interactive systems based on the visual sentence theory. We explore the dimensions of time and space in visual interaction and discuss the importance of the notions of scaffold and frame of reference. Usable visual systems are realised by designing an augmented version of the user task visual language and a scaffold visual language supporting user naviga... View full abstract»

    Visual languages (VLs)-invented outside the visual programming language (VPL) community-are quite successfully used around the world. There are, for example, international VL standards used in the telecommunication, software engineering and automatic control engineering industries, but alas, most of these language standards were defined without knowing the VL definition and design principles devel...

    We propose a multimedia script language named “Meta Script” which describes the structures of movies based on the counterpoint theory in music. As a case study, we describe a structure of Bach's “3 Part Invention No. 4” with Meta Script, and produce a movie according to the script. From this experiment we confirm that Meta Script works well as a counterpoint structure descr... View full abstract»

    Debugging parallel programs challenges users due to the high complexity established by multiple, concurrently executing and communicating tasks. While error detection is still mainly based on textual representations, only graphical displays provide capabilities for managing the complexity. With the event graph model, investigations about occurring events and their connections can be performed. In ... View full abstract»

    With respect to the historical role and capabilities of visual language, I consider the following three themes: why visual language now; what is visual language; and the paradigm shift of visual language. We are living in an age with the greatest volume of information in history. Each individual needs to be aware of both the purpose and how to make use of this information. Visual language serves a...

    In many fields of science, as well as in real life, visual expressions are used to communicate data, and to perform or document activities. Reproducing such notations in a computerized environment makes possible the development of interactive systems, through which users can easily perform their activities. In this paper we describe how the combination of two methodologies-CVE (Cooperative Visual ... View full abstract»
