    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»

    Iconic environments intend to provide expressive tools to implement, to debug and to execute programs. Moreover its pictorial constructs guide the user to design algorithms in an interactive fashion. Visual interfaces are especially required whenever programs run on an heterogeneous and reconfigurable multiprocessor system oriented to image analysis. Pictorial tools help the user to control the sc... View full abstract»

    Glotos is a visual representation of Lotos, and both are semantically equivalent. In this paper, a Glotos layout tool is described, which takes either the Lotos or the edited Glotos specification as input and generates an aesthetic Glotos layout as output. In both cases, a Glotos syntax tree is created. A bottom-up procedure is then used to calculate the boundary for each Glotos constructor. Final... View full abstract»

    Describes work in progress on a visual programming language for virtual environments, called Lingua Graphica. Three-dimensional, solid language constructs are used to visualize and compose programs and higher-level scripts while inside of a virtual environment. This is a departure from the normal way that virtual environments are developed and used. Using Lingua Graphica to specify the behaviors d... View full abstract»

    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»

    The authors describe a design methodology for iconic languages based upon the principle of semantic compaction. The design methodology serves two purposes. First of all, it is a descriptive model of the design process for the iconic language of the Minspeak system. Second, it is also a prescriptive model for the design of other iconic languages for human-machine interface. This investigation raise... View full abstract»

    The authors present VAMPIRE a visual system for rapid generation of iconic programming systems. VAMPIRE uses a graphical class editor to construct a hierarchy describing an iconic language's structure. Each node in the hierarchy represents an abstraction of a group of language elements; each leaf represents an icon which can be placed into a program. Attributes are added to each `class' in the tre... 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»

    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...

    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»

    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»

    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.

    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...

    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»

    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»

    An abstract execution model for demonstration-based and example-based visual languages is presented. The formalism, causality graphs, are a simplified version of Petri nets, and possess similar execution properties. The author shows how programming, compilation, and execution of demonstration-based languages may be expressed as the construction and analysis of causality graphs. The model provides ...

    This paper presents a new approach to automatic layout of diagrams: layout-by-example. In this approach, a layout is produced by applying the layout rules which are generated from layout examples called stereotypes. A fuzzy visual language is proposed for specifying stereotypes of diagram layout. The concept of fuzzy theory is incorporated into parsing visual sentences representing stereotypes and...

    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»

    In this paper we give algorithms for the construction of a 2D interactive parser which helps a user to construct correct two-dimensional iconic sentences according to positional LALR grammars. At each step of the parsing process the user is provided with a feasible set of icons. Moreover, the areas on the screen where each icon in the set may be placed are highlighted. In this way both syntactic a... View full abstract»

    Higher-orderness, highly interactive, a great amount of flexibility, color, increasing the visual extent and parallelism are all catchwords related to the development of visual languages. The paper reports on the functional visual language VisaVis coming up with a new user interaction strategy integrating higher order functions smoothly.

    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»
