    Software maintenance programmers face the daunting task of understanding and modifying complex, unfamiliar programs that contain delocalized plans (conceptually related code that isn't located contiguously in a program). The authors' research shows that programmers use an as-needed strategy when searching for the delocalized components which they need to understand. They have developed a maintenan...

    Describes work in progress towards development of integrated pen-based software systems for processing visual languages (VL). The primary assumption is that graphical input, editing and VL parsing facilities can be treated as system resources to be shared among many applications. Prototypes of a pen-stroke editor, VL parser, and VL-based application are described View full abstract»

  • A boundary notation for visual mathematics

    Publication Year: 1992 , Page(s): 267 - 269
    Cited by:  Papers (2)

    Instead of traditional mathematical notation, one can describe formal mathematical systems in a visual form. While the traditional notation uses a linear sequence of symbols, visual mathematics uses a boundary notation, which is comprised of objects and boundaries to enclose objects. Boundary notation is abstract, decoupling the underlying mathematics of a system from its visual representation. On... View full abstract»

    The authors present an experiment supporting the thesis that visual languages are well suited for programmers whose native language is not English. They first analyze the particular problems of the target group, Arabic speakers, in comprehending Pascal program structures and present a number of previously proposed solutions to this problem. They present their own solution, a visual programming env... View full abstract»

    KJ-Editor simulates the arranging activity of index cards on a desk. Such activity is essential for carrying out the so-called KJ method, which is very popular in Japanese business society. The KJ method itself is briefly described. The most serious problem when the card arranging activity is simulated on a computer is how to get a panoramic view of all the cards, and a trial for this problem is p... View full abstract»

    Low-cost implementations of graphical user interfaces (GUIs) have relied on the widget library framework. Although conventional widgets are suitable for developing typical GUIs with predetermined interaction styles, application-specific customization of interactions is rather difficult, especially for a non-programmer. Instead, the authors propose a new framework whereby the GUI designers can arbi... View full abstract»

    Addresses the issue of the formal definition of hierarchical visual languages. It is motivated by interest in formal system development and the use of visual languages as formal specification tools. The paper presents a formal model of hierarchical visual languages. This model, called HIRG (hierarchical icon-replacement grammar), is then extended to enable the integration of textual and visual not... View full abstract»

    If future electronic documents are to be truly useful, one must devise ways to automatically turn them into knowledge bases. In particular, one must be able to do this for diagrams. This paper discusses biological diagrams. The author describes the three major aspects of diagrams: visual salience, domain conventions and pragmatics. He next describes the organization of diagrams into informational ... View full abstract»

    Complex hardware systems design demands the effective use of organized approaches to design. The VHSIC hardware description language (VHDL) was developed for use in the design process. Traditionally, engineers have developed hardware descriptions based on schematic circuit diagrams, which are a visual notation. When using VHDL, designers are hampered by the cumbersome nature of the language syntax... View full abstract»

    Growing interest in visual languages has triggered new extended research into the specification and parsing of multi-dimensional structures. The author discusses the need for a visual specification formalism and introduces such a technique by augmenting logic programming with picture terms which can be considered as partially specified pictures. He defines how to match picture terms and how to int... View full abstract»

    Animation of algorithms makes understanding them intuitively easier. This paper describes the software tool Raft (Robust Animator of Fault Tolerant Algorithms) which allows the user to animate a number of fault tolerant parallel algorithms which achieve fault tolerant execution. The novelty of the system is that the interface allows the user to create new on-lin... View full abstract»

    It would seem that some of the most successful applications of visual programming have been in problem domains that are fairly restrictive and well-defined. It is swiftly becoming realized that the creation of educational courseware is one such domain for which are investment of visual programming effort is amply repaid by the pedagogical benefits. Visual languages in this class range from, at one... View full abstract»

    Automatic graphic object layout methods have long been studied in many application areas in which graphic objects should be laid out to satisfy the constraints specific to each application. In those areas, carefully designed layout algorithms should be used to satisfy each application's constraints. However, those algorithms tend to be complicated and not reusable for other applications. Moreover,... View full abstract»

    Gives a general framework for visual proving based on logic programming, by giving a mapping from figures to formulas. For a figure consisting of graphic objects and constraints, the author formally defines the set of facts that are visible in the figure. As a result, one can rigorously formalize the soundness of reasoning by figures View full abstract»

    Constraint based drawing programs require users to understand and manage relationships between drawing elements. By establishing constraint relationships among elements the user effectively programs the drawing's behavior. This programming task requires a more sophisticated visual interface than conventional drawing programs provide. Users must have available-in a convenient format-information abo...

    Two systems are introduced that increase the information density of textual presentation by reconsidering text as pictures, expanding the range of written expression. Both schemes indicate nested associativity and both employ stripes, but in different styles: Blush uses large-scale vertical gutters, superimposed as reverse-fielding on indented outlines of computer programs; Zebrackets uses small-s...

    The authors address the question of event-handling for declarative visual languages. In the approach presented, system-level, interactive, and user-defined events are fully-supported, while still maintaining the property of referential transparency. An approach to time termed temporal assignment provides a unifying mechanism for events to be defined as ordinary sequences of values, and conversely ... View full abstract»

    The general term software visualization refers to graphical views or illustrations of the entities and characteristics of computer programs and algorithms. This term along with many others including data structure display, program animation, algorithm animation, etc., have been used inconsistently in the literature, which has led to confusion in describing systems providing these capabilities.

    The author's understanding of a concept is tightly connected to the way one represents that concept. Traditionally, mathematics is presented textually. As a consequence, novice errors in elementary algebra for example, are due as much to misunderstandings of the nature of tokens as they are to miscomprehensions of the mathematical ideas represented by the tokens. The author outlines a spatial alge... View full abstract»

    Various multimedia authoring environments have been developed, resulting in a variety of approaches as to how such presentations are structured and authored. Implicit in these systems is a data model for composing multimedia objects and a user interface model for the authoring activity. Making these models explicit is one goal of this work, since it will lead to the design of easier-to-use and mor... View full abstract»

    Predictive, Earley-style parsing for unrestricted relational grammars faces a number of problems not present in a context-free string grammar counterpart. Here a subclass of unrestricted relational grammars called fringe relational grammars is proposed along with an Earley-style recognition algorithm. The grammar makes use of fringe elements (the minimal and maximal elements of partially ordered s... View full abstract»
