    The authors describe a general-purpose tool for the specification and interpretation of visual languages based on the formalism of SR grammars. The major components of the system are a structure analyzer and an interpretation module. The structure analyzer consists of a general diagrammatic editor and a lexical analyzer. The main task of the lexical analyzer is then the identification of the relat... View full abstract»

    Visual programming languages have facilitated the application development process, improving our ability to express programs, as well as our ability to view, edit and interact with them. Yet even in programming environments, productivity is restricted by the primary input sources: the mouse and the keyboard. As an alternative, we investigate a program development interface which responds to the mo... View full abstract»

    When implementing textual languages, formal grammars are commonly used to facilitate understanding languages and creating parsers. In the implementation of a diagrammatic visual programming language (VPL), this rarely happens, though graph grammars with their well established theoretical background may be used as a natural and powerful syntax definition formalism. Yet all graph grammar parsing alg... View full abstract»

    We discuss the visual focusing and transition techniques embodied in a Bellcore Java applet called AMIT (Animated Multiscale Interactive Treeviewer), whose purpose is to improve Web information access. AMIT integrates fisheye tree browsing with search and filtering techniques. Multiple foci are selected by direct manipulation, content-based search, variable scoring functions, and what we call node... View full abstract»

    The large number of programming languages in the world is, in part, a consequence of the broad spectrum of human preferences for different notational styles and semantic models, which seems to depend on personal background as well as the application area involved. A move from text to visual languages seems to increase variety, because of the greater syntactic flexibility allowed; a single person m... View full abstract»

    The objective of the Visual Programming Challenge (VPC) is to focus the various visual programming approaches, both research and commercial, on a specific problem as a means of providing a comparative analysis. The competition domain is a problem involving quasi-real-time control of a robotic vehicle. The control of these robotic vehicles is representative of programmable control problems that mig...

  • Pretty-printing of visual sentences

    Publication Year: 1997, Page(s):242 - 243
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (176 KB)

    When input sentences are processed in some manner, say evaluated with some set of rules, the resulting sentence must be pretty-printed in order to be presented to the user. We introduce a technique called “Share-Where maintenance” which is used to preserve layout information by annotating abstract representations of visual sentences. The annotations in the abstract representation point... View full abstract»

    GUIDO (GUI for DOcuments) is a visual information retrieval interface (VIRI) that focuses on retrieval rather than on document organization. This visual document retrieval system utilizes two reference points at a time, three metrics (the city block metric, the Euclidean metric and the maximal distance metric) and four retrieval caps (the disjunctive, conjunctive, elliptical and Cassini oval model...

    Although people can readily use and generate analogies in everyday discourse to relate disparate domains, even most of today's end user programming languages provide no support for creating analogies. Finding ways to represent analogies that allow users to express relations between code fragments via analogy is challenging. Within Agentsheets with VisualAgentalk (AS-VAT) a “programming by an...

    Computer-based visual languages have been developed primarily in order to help people program and operate computers. Now that many people in the world have personal computers with good graphics and Internet connections, we are seeing a great deal of informal electronic visual communication via Web pages. More formal visual languages can be expected to appear on the Internet in the near future. Vis... View full abstract»

    Version control and module management are very important in practical software development. In UNIX, the Revision Control System (RCS) or the Source Code Control System (SCCS) is used in general as a version control tool. However, they (1) lack the ability to explicitly display version changes; (2) require complicated commands to be typed; and (3) lack the ability to manage multiple files and modu...

  • From visual language specification to legal visual interaction

    A crucial requirement of visual interaction is to prevent users from performing incorrect operations. This requires the computer environment to trap illegal users' actions. On the other hand, users should have enough freedom in their interaction, typically by not being forced to follow predefined sequences of operations, yet being able to develop their line of thought in solving their problems.

    A teleaction object (TAO) is a multimedia object with associated hypergraph structure and knowledge structure. The user can create and modify the private knowledge of a TAO so that the TAO will react automatically to certain events. The hypergraph structure supports the effective presentation and efficient communication of multimedia information. TAOs are extremely valuable since they greatly impr... View full abstract»

    With the introduction of the computer, narrative experiences can be found in new media applications as diverse as MUDs, arcade games and 3D immersive environments-and new applications are being created all the time. The form these narrative experiences take are as diverse as their mediums: from the experiential stories of MUDs to the intricate branching plot paths of adventure games. But as with t...

    Modeling of human knowledge and reasoning requires the formulation of uncertainty in its various forms. Fuzzy logic was introduced to directly support these applications (H. Zimmermann, 1991). Fuzzy control (FC) which is based on fuzzy logic allows one to control complex systems based on qualitative information like human knowledge (C. Geiger and G. Lehrenfeld, 1994). In fuzzy logic, fuzzy sets ar... View full abstract»

    Data structures are more easily understood when they are presented visually rather than textually. We have developed a system, called Calypso, to allow the visual definition of data structures programs using pictorial pattern/action pairs in an imperative setting. Calypso is based on a general framework for building and combining visual notations in various domains. This framework permits Calypso ... View full abstract»

    Although the idea of reusing code is very appealing, effective reuse has long been acknowledged as a problem. To help address the difficulties, many advocate strong management commitment to code reuse, leading to the treatment of code as an asset to be carefully managed in a well-organized repository. However, the advent of the Web may bring a change to this outlook encouraging informal, loosely-o... View full abstract»

    An algorithm animation environment called Jeliot is presented. Jeliot allows a Web user to visualize his/her own algorithms, written in Java, over the Internet. Jeliot is based on self-animation of data types: the user selects the data objects of the source code which he/she wants to visualize, and Jeliot produces the animation automatically View full abstract»

    Diagrams are always used when communicating complex situations. Diagram editors support the user when editing diagrams on a computer. However creating diagram editors is expensive and time consuming. Frameworks that can be customized for the specific diagram classes considerably reduce these costs. In previous work, the framework DiaGen using an internal hypergraph model and offering syntax direct... View full abstract»

    Image/video data contains numerous information such as objects, image attributes (e.g., color, height, width) of objects, and various semantic contents. Provision of a scheme for the retrieval of video data content is still one of the unfulfilled issues. The authors propose a method of retrieving video data from films by way of specifying the semantic content of scenes. Related to the creation of ... View full abstract»
