    Formalisms for visual language specification have been investigated for more than two decades. However, there has been little attempt to develop a systematic and comprehensive hierarchy of visual languages based on formal properties. Given the importance of the Chomsky hierarchy in the theory of textual languages and the difficulty of comparing the different visual language formalisms, it is clear... View full abstract»

    We describe the object-oriented editor GenEd supporting the design of specifications for visual notations. Prominent features of GenEd are: it is generic, i.e. domain-specific syntax and semantics are specified by users; built-in parser for actual drawings, driven by formal specifications; powerful reasoning capabilities about diagrams and their specification. GenEd's specification language is bas... View full abstract»

  • Design benchmarks for VPL static representations

    Publication Year: 1996, Page(s):263 - 264
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (200 KB)

    A weakness of many interactive visual programming languages (VPLs) is their static representations. Lack of an adequate static representation places a heavy cognitive burden on a VPL's programmers, because they must remember potentially long dynamic sequences of screen displays in order to understand a previously-written program. Building upon the cognitive dimensions developed for programming lan... View full abstract»

    The research involved a qualitative and quantitative study of statements made by computer scientists about the ways in which they think that visual programming assists the thought processes of the programmer. This type of metacognitive knowledge has been shown in psychological experiments to have significant effects on performance in cognitive tasks. It is particularly important in the design of p...

    It is commonly accepted that non-logicians have difficulty in expressing themselves in first order logic. Part of the visual language community is concerned with providing visual notations (declarative diagrams) which use visual cues to make the structuring of logical expressions more intuitive. One of the more successful metaphors used in such languages is that of set inclusion, making use of the... View full abstract»

    Algorithm animation can be an effective tool for understanding the behavior of programs. However, most approaches towards algorithm animation have focused on evermore sophisticated graphical depictions of programs, and not on the process of how students can develop and make use of animations in an educational setting. We describe the AlgorithmExplorer, a flexible algorithm animation system targete... View full abstract»

    Fundamental to the design of visual languages are the goals of facilitating communication between people and computers, and between people and other people. The Object Block Programming Environment (OBPE) is a visual design, programming, and simulation tool which emphasizes support for both human-human and human-computer communication. OBPE provides several features to support effective communicat... View full abstract»

    Authoring multimedia documents involves coordinating various types of media items in time and space. To be effective, authoring requires integration tools that are highly interactive. In addition, the notion of “time” must be made explicit and flexible so that users may define and manipulate the temporal behavior of documents directly and flexibly. The authors describe an interactive f... View full abstract»

    The design of abstract or physical structures has much in common with the design of software structures, particularly when the structure in question has a mechanical or computational behaviour; such as a digital circuit. Like programming language systems, design systems must have expressive power sufficient for representing any design, a simulation mechanism for debugging the artifact under constr...

  • Perspective viewing, anaglyph stereo or shutter glass stereo?

    Publication Year: 1996, Page(s):192 - 193
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (200 KB)

    This paper describes a case study that assessed the strengths and weaknesses of 3D display modes: perspective viewing, anaglyph stereo and shutter glass stereo. We followed the hypothesis that stereo viewing allows a faster and more accurate recognition than the anaglyph and the perspective viewing. For our case study, we used organic molecules. Although these have inherent spatial information we ... View full abstract»

    Studies designed to demonstrate the pedagogic effectiveness of algorithm animation programs have been markedly unsuccessful, in spite of high expectations. We present a framework for future experiments based upon design issues particular to algorithm animation, plus pertinent educational considerations. Guidelines are drawn from a meta-analysis of previous work and experiments we have performed View full abstract»

    The availability of large image databases is emphasizing the relevance of filters, which permit one to focus on a small subset of data. Visual specification of such filters provides a natural way to express content-oriented queries. To support a high power of expression, an original visual language is proposed for the symbolic representation of the semantics induced by the color quality and arrang... View full abstract»

    Fisheyeing, in combination with zooming, addresses the scalability problem in visual languages by allowing the user to see a portion of a large visual program in detail while at the same time viewing the remainder of the program in somewhat less detail. We describe how fisheye views have been incorporated in the VIPR (VIsual PRogramming) environment. We begin by discussing the ways in which VIPR i... View full abstract»

    In order to manage visual interaction problems, we deepen a formalisation of visual languages, based on the notion of visual sentence, introduced in a previous paper (Bottoni et al., 1995). Visual conditional attributed rewriting systems (vCARWs) are proposed for the specification of visual languages. We argue that vCARWs can be viewed as a generalisation of conditional set rewrite systems, which ... View full abstract»

    An often-mentioned advantage of rule-based programming languages is that a program can be extended simply by adding a few more rules. In practice however the rules tend to be dependent on each other and instead of just adding rules, existing rules need to be changed. The unique rules in Cartoonist, a rule-based visual programming environment to build simulations, provides a solution to this proble... View full abstract»

    The main goal of the article is to evaluate the suitability of visual programming languages, i.e., Pictorial Janus (K. Kahn and V. Saraswat, 1990), for the modeling of complex systems and their control strategies. These systems can be seen as networks of communicating objects. Objects select strategies for suitable actions based on incoming messages. Our field of investigation is in computer integ... View full abstract»

    Unlike current GUI or WIMP style interfaces, non-WIMP user interfaces, such as virtual environments, involve parallel, continuous interactions with the user. However, most current visual (and non-visual) languages for describing human-computer interaction are based on serial, discrete, token-based models. The paper introduces a visual language for describing and programming the fine-grained aspect... View full abstract»

    Display-based problems in current spreadsheet systems have been identified as conceptually simple problems requiring complex solutions. In this paper, we examine such display-based problems and discuss an approach aimed at keeping the solutions of conceptually simple problems simple. This approach is based on functional abstraction, direct manipulation of regions, and invocation polymorphism which... View full abstract»
