    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

    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.

    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»

    VISPATCH (VISible event disPATCH) is a graphical rule-based programming language based on event-driven graphics rewriting that is suitable for expressing user interaction. The VISPATCH interpreter can modify rules by other rules as well as graphical objects. This makes it possible to create a programmable interactive system such as a graphic editor 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»

    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...

    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»

  • Designing cut and paste in a visual environment

    Publication Year: 1997, Page(s):448 - 449
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (152 KB)

    Cut and paste operations are common enough that users expect them to be provided in any application. However, some applications in which cut and paste operations are desirable have ambiguities which make it difficult to interpret the user's intent. A general method of designing this part of the system is desirable. Although current graphical environments exist which offer a simple version of cut a... 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 suggest a solution for iterative processing in data flow diagrams based on the notion of a conditional data flow switch, and a specialized iterative construct based on pattern matching for vectors and matrices. Both of these constructs can be seamlessly incorporated into V, a data-flow visual programming language. We demonstrate how these constructs may be used to reveal the spatial/temporal du...

    Both visual data flow and logic based programming languages have their merits as declarative languages for certain application domains. Combining their concepts to program with data flows and backtracking seems to be a promising idea, which lead to the development of BDL. BDL is a visual data flow programming language with constructs for nondeterministic programming and constraint checking. Its no... 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»

    Previously (J. Puigsegur et al., 1996), we presented a visual declarative programming language based on two main graphical constructs: directed acyclic graphs representing predicate application and graphical set inclusion representing logical implication. We showed that with these simple visual constructs we can cover most of the representational demands of computational logic allowing a blend of ... 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»

    The authors present a visual environment for the construction and observation of scripted computational structures. The visual instruction set consists of typographic operators such as color, alignment, and size, enabling the user to create free-form designs of kinetic typography.

    We describe PUIST, a visual language for graphical interface specification and prototyping. PUIST uses a Petri net notation, with a declarative means of defining nets which have complex, yet regular interconnections. This significantly improves the understandability of large specifications, permitting PUIST to be used for complex interface component specification and prototyping 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 propose the notion of a visual design pattern (VDP), which is a visual abstraction representing design aspects in parallel data-flow programs. VDP serves as a flexible and high-level structure of reuse for visual parallel programming. We introduced the support for this notion into the visual parallel programming environment, KLIEG, allowing definition and use of patterns with a simple and easy ... View full abstract»

    The design and development of a visual computer system for the modelling and simulation of human movements are described. A multimedia language named HAL (Human Animation Language) allows human figure movements to be generated in a graphical and intuitive way, accomplishing human-computer interaction through a 3D icon-graphic interface.

    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...

    Writing and managing programs for parallel systems is a difficult task. It is a great challenge for designers of visual programming languages to provide tools that will help in the process. The paper describes a new graph based tool called Visper that provides a multi dimensional environment for program composition. Our approach combines different levels of abstraction at which parallel programs a... View full abstract»
