    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»

    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...

    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»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1264 KB)

    We develop an analysis of visual knowledge and the use of pictures in electronic communication. We focus in particular on indexical images, which are at work in our current practice of navigation in multimedia documents and the World Wide Web. For this purpose, we base our study, on the one hand, on semiotics, the core concepts of which were introduced by C.S. Peirce at the beginning of the 20th C... View full abstract»

    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»

    Publication Year: 1999, Page(s):90 - 95
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (352 KB)

    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»

    Geared to complement UML and the specification of large software systems by non-mathematicians, spider diagrams are a visual language that generalizes the popular and intuitive Venn diagrams and Euler circles. The language design emphasizes scalability and expressiveness while retaining intuitiveness. In this paper, we describe spider diagrams from a mathematical standpoint and show how their form...

    Recently, many companies often provide some trial versions of their systems to the web users. The main purpose for this is to present the usability of their systems. There are two advantages in presenting the system as an applet. One is reducing user's trouble, because an applet can be downloaded automatically and the user does not have to install the system. The other is reducing the version-up c... View full abstract»

    Recently a new metaphor for diagramming, the intelligent diagram has emerged. This new metaphor provides an excellent basis for diagram beautification since it automatically collects geometric constraints which capture the semantics of a diagram during diagram construction. By applying visual-language-specific layout rules which impose additional desired constraints on the diagram component placem... View full abstract»

    Previous research suggests that the graphical metaphor should increase the usability of visual programming languages (VPLs) by providing an instructional aid when learning to use the language. This paper describes three experiments which manipulated the degree of metaphor in VPLs. In the first, an implicit pictorial metaphor was added to a data flow language, while in the second and third an expli... 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»

    The formal treatment of visual languages is often based on graph representations. Since the matter of discourse is visual languages, it would be convenient if the formal manipulations could be performed in a visual way. We introduce visual graphs to support this goal. In a visual graph, some nodes are shown as geometric figures, and some edges are represented by geometric relationships between the... View full abstract»

    Arguing for the need to increase awareness on the WWW we describe a system that makes activity on a Web site perceptible in the physical world. Reviewing the benefits and limitations of a first prototype that used an audio-only interface, we explain why and how we have improved it by adding a visual interaction mechanism View full abstract»

    We present a first treatment dealing with semantics of visual spatial query languages for GIS using a suitable description logic. This decidable space logic is described and its usefulness for GIS exemplified. The logic supports the specification of semantics, reasoning about query subsumption and about applying default knowledge View full abstract»

    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»

    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»

    Timelines are used as the basis for representing events over time. When they are combined with a geographical map, they show the spatiotemporal pattern of those events. This spatiotemporal line depicts temporal pattern of events with respect to their spatial attributes. To help users observe patterns with respect to different spatial viewpoints and periodical constraints, we propose an interactive... 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»

    We are interested in three-dimensional visual programming environments in particular. The conventional visual programming systems mainly focuses on two-dimensional pictorial programming. A big problem is that two-dimensional visual programming systems fail to manage a lot of pictorial programming elements.

    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»
