    A visual database front-end for handling query result presentation and exploration is presented. The system is based on a formal interaction structure called a hypertable, and can be seamlessly integrated with any visual semantic query language adopting a data model that supports the notion of relationship cardinality. We aim at overcoming two kinds of problems in the interaction with tabular disp... View full abstract»

  • From visual language specification to legal visual interaction

    Publication Year: 1997, Page(s):234 - 241
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (836 KB)

    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. Th... 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»

    The paper shows how language technologies such as the automatic generation of parsers for analyzing user actions and visual parsing can be applied to build a flexible tool specialized in complex specification tasks, namely the configuration of distributed applications. The central issue is to propose to structure the workspace through a syntax of user actions on one hand, and a syntax of visual re... View full abstract»

    We propose an interactive document keyword layout technique that enables browsing and manipulation of a collection of documents visually. This layout technique applies a force directed graph drawing algorithm and clusters documents and keywords by reacting to a user's interaction dynamically. An example of visual interaction is demonstrated on an experimental system View full abstract»

    Building environments that use visual techniques (visual environments) is still expensive in labour. We present an object oriented framework for compound documents, called HotDoc, that can be used for building visual environments rapidly. We give an example by describing a user interface for an extended spreadsheet environment called Simple. We focus on spatial composition control which is support... 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»

    We introduce a visualization framework called DelaunayMM for querying and presenting multimedia information in distributed databases. Users can tailor the layout of virtual documents containing multimedia information at the same time as they specify their contents in an intuitive yet formal way, using a Web-available interface. The data model that we propose is object-oriented, and the ... View full abstract»

  • Toward visual constraint programming

    Publication Year: 1997, Page(s):420 - 421
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (192 KB)

    The authors present a visual constraint programming language which is based on a very simple visual syntax composed of a few basic geometric shapes that correspond to the traditional clausal (i.e. textual) syntax of constraint logic programming. It is however powerful and efficient, as the main idea of their approach is to compile down the visual syntax into the clausal constraint logic programmin... View full abstract»

    3D-graphics are becoming popular in a steadily increasing number of areas such as entertainment, scientific visualization, simulation, and virtual reality. Despite this rapid growth the generation of animated 3D scenes is by no means trivial. Since animated 3D objects evolve over time the authors denote these objects as 4D. The article presents a novel approach to the rapid prototyping of 4D model... View full abstract»

    In this paper a new approach to the problem of quality evaluation for a software visualization system is suggested. The following topics are discussed: the visual language of software visualization systems; significant units of the visual language; visual expressiveness of a visual language; visual informativeness; adequacy in visualization; and visual metaphor View full abstract»

    We define a graph based visual query language for object databases, called QUIVER. Most graph based query languages proposed in the literature view queries either as constraint (pattern) graphs or as data flow graphs. QUIVER, however allows constraints and data flow to be combined in queries. This combination of constraints and data flow is motivated by the need to support comprehensive object mod...

    We present a visual language for the high level specification of authorization policies in automated environments. In order to accomplish the task, the visual language needs to provide an intuitive way to specify complex security concepts. We propose a visual language, using the Calendar-Form-Lock metaphor, to efficiently handle high level security policies and low level security details. Moreover... View full abstract»

    The graphical requirements for implementing a visual language include defining the visual elements of the language, the rules for connecting them together, and the graphical relationships that must be maintained once they are connected. The solutions for these graphical requirements are intricate and inherently difficult to implement. The resulting implementations tend to be so specialized as to b... View full abstract»

    We present a framework of syntactic models for the definition and implementation of visual languages. We analyze a wide range of existing visual languages and, for each of them, we propose a characterization according to a syntactic model. The framework has been implemented in the Visual Language Compiler-Compiler (VLCC) system. VLCC is a practical, flexible and extensible tool for the automatic g... View full abstract»

    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...

    We describe a collaborative research effort between the faculties of computer science and architecture, investigating a special purpose visual language to be used to generate architectural forms. This language forms part of a larger system intended to automate the process of generating architecturally designed houses. The rules which can be specified using the language described here are used to p... View full abstract»

    Until now, attempts to extend the one way constraint evaluation model of the spreadsheet paradigm to support complex objects, such as colored circles or user defined types, have led to approaches featuring either a direct way of creating objects graphically or strong compatibility with the spreadsheet paradigm, but not both. This inability to conveniently go beyond numbers and strings without stra... View full abstract»

    The minor expressiveness of text with respect to visual features has determined the prevalence of visual interaction paradigms for specifying queries in systems for image retrieval by content. To cope with user's subjectivity, the description of image visual contents should exploit different levels of detail in image representation. We present a system which supports image indexing and retrieval b... View full abstract»
