    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

    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»

    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»

    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»

    This paper discuses visual information representation from the perspective of human comprehension. The distortion viewing paradigm is an appropriate focus for this discussion as its motivation has always been to create more understandable displays. While these techniques are becoming increasingly popular for exploring images that are larger than the available screen space, in fact users sometimes ... 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»

    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 effective use of visual languages requires a precise understanding of their meaning. Moreover it is impossible to prove properties of visual languages like soundness of transformation rules or correctness results without having a formal language definition. Although this sounds obvious, it is surprising that only little work has been done about the semantics of visual languages, and even worse... 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»

    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»

    There is a current trend in the visual programming community towards the visualisation of high level programming constructs and techniques. There seems to be no reason, however, why low level programming should not also benefit from the advantages to be gained from visual representation. We, therefore, have investigated the feasibility and possible application of visual programming techniques to l... View full abstract»

    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»

    We describe our experiences in applying visual programming to simple robot control. Three different approaches are discussed: using a visual procedural programming approach; a visual, object oriented approach (both of these using a general purpose visual programming language); and finally a special purpose visual programming language based on subsumption architecture View full abstract»

    Animation is a natural way to represent dynamic behaviour, but the lack of models and the difficulty of programming animation have limited its introduction into the user interface (UI). Visual programming techniques may greatly simplify animation creation, but most of the current approaches are limited to a specific application class. The paper describes HandMove, a general and powerful model for ... View full abstract»

    We present the design of the visual query system VISCO that offers a sketch-based query language for defining approximate spatial constellations of objects. VISCO smoothly integrates geometrical and topological querying with deductive spatial reasoning. It is based on a strong physical metaphor visualizing semantics of query elements. Approximate queries rely on combined topological and geometrica... 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...

    Visual programming approaches are limited in their usefulness if they do not include a profile of their users that defines exactly who is attempting to solve what kind of problems using which tools and why. Without such a definition, visual programming approaches can end up as solutions in search of problems. Reconceptualizing-programming environments as layered behaviour processors in the context...

    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»

    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...

    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»
