An auralization technique for representing inheritance relationships in an object-oriented programming language is proposed. The inheritance relationships are represented by inclusion relationships of sound passages, which are called sound glyphs. A prototype system using this technique can assign unique sound glyphs to all classes in Java 2 standard edition version 1.2.2 whose class library has m... View full abstract»

Human dialogue is so complex that definitively analysing patterns of conversation may well be impossible. Within a conversation, all the complexities and ambiguities of natural language exist and each speaker will have his/her own speech characteristics and moods. Examining these characteristics through text dialog can be a demanding cognitive task. One reason is because the whole conversation can... View full abstract»

This paper reports work in progress on the analysis and visualization of the spatial and temporal distribution of user interaction data collected in three-dimensional (3D) virtual worlds. Two tools are introduced. The "WorldMapper" reads in a so-called propdump file and creates a 2D clickable map showing the layout of the world as well as interaction possibilities such as teleports and clickable w...

We describe a virtual reality widget library and two medical applications. These applications, built on the widget library, make use of collaborative interaction techniques. These techniques support a high degree of precision with respect to manipulation of data and data parameters. The 3D widgets are synchronized between collaborating clients in order to facilitate the high degree of interactivit... View full abstract»

Dynamic interactive visualisations (DIVs) are intended to help coordination and collaboration, through augmenting existing forms of synchronous communication (i.e. phones, face to face, walkie-talkie). A central feature of a DIV is active user involvement: users are required to create, annotate, and change the information visualisation to represent the changes in the activity space they are concer...

We show that two-point G/sup 2/ Hermite cubic spline interpolation to a smooth spiral is a spiral. Its unit tangent matches given unit tangents and its signed curvature matches given signed curvatures at end points of the given spiral. Spiral segments are useful in the design of fair curves and have the advantages that there are no unplanned curvature maxima, curvature minima, or inflection points... View full abstract»

In this paper we study the monotonicity preservation of Wang-Ball system and of another system of polynomials useful in computer-aided geometric design. We also prove that rational Wang-Ball representations are not always monotonicity preserving. View full abstract»

A mobile navigation system is designed and implemented in this paper. This system can be applied to the digital libraries to make a real time query in the library. The information provided for this system includes data and voice. The major functions of this system include information access and destination guidance. Other value-added functions can also be finished easily. There are three major par... View full abstract»

We present a new visualization approach for metadata combining different visualizations into a so-called SuperTable accompanied by a Scatterplot. The goal is to improve user experience during the information seeking process. Our new visualizations are based on our experiences developing a visual information retrieval system called INSYDER to supply small and medium size enterprises with business i... View full abstract»

Understanding the information gathered thus far in a criminal investigation is of great importance, particularly in terms of guiding its future course. Since the late 1980's the use of software tools to provide visualisations of this information has become increasingly common. The objective of such tools is to provide, in a readily comprehensible way, the social network of all the people involved.... View full abstract»

Information visualisation systems often have to cope with presenting large amounts of data. In this paper we look at the problem of reducing the display density through the use of random sampling. We review some of the uses of sampling and examine density reduction techniques currently used in visualisation. We then look at a proposed novel visualisation that utilises sampling and discuss many iss... View full abstract»

Animated intelligent agents play an important role in dynamic virtual environments. They are able to perform behaviours based on internal states and external stimuli. Animation techniques are crucial to agent behaviour visualization in order to achieve effective interaction between agents and human users. This paper proposes a new animation procedure to visualise realistic intelligent agent behavi... View full abstract»

This paper addresses the problem faced by animators in creating accurate and realistic walk cycles, as well as coherent interaction with the immediate production environment. Modern software packages often contain modules for implementing dynamics, without the need for specialist programs. In this paper, how to best use these modules to create the desired realistic effects is explored and expanded... View full abstract»

We describe a visual development system for exploring "face space", both in terms of facial types and animated expressions. Imagine an n-dimensional space describing every humanoid face, where each dimension represents a different facial characteristic. Within this continuous space, it would be possible to traverse a path from any face to any other face, morphing through faces along that path. It ... View full abstract»

This paper proposes a new approach for motion retargeting, i.e., adjusting motion-capture data to different characters and scenes. For achieving universality, the existing retargeting techniques often become absolutely impractical for most of real-life applications. In contrast, we did not try to create a technique that can deal with practically any motion, but concentrated on creating a practical... View full abstract»

A novel algorithm for computing RSIC intersection curves of two surfaces of revolution is presented; it subdivides a surface of revolution into a collection of coaxial spherical strips, by subdividing its generatrix into a collection of C/sup 0/ and C/sup 1/ coaxial circular arcs correspondingly. So the intersection problem of two surfaces of revolution is reduced to an intersection problem of two... View full abstract»

In computer-aided design, geometric modeling by constraints enables users to describe shapes by relationships, called constraints between geometric elements. The problem is to derive automatically these geometric elements. Many resolution methods have been proposed for solving systems of geometric constraints. Geometric methods can be very efficient but are only applicable to particular kinds of p... View full abstract»

In the initial process of exterior design of a product, designers often get the idea of a designing product form as silhouette lines and boundary lines. Therefore, if the 3D model is constructed from silhouette lines and boundary lines, designers will be significantly assisted in the process of external form design. This paper describes a system to construct a 3D model with complex curved surfaces... View full abstract»

This paper deals with "computer aided chair design system" based on form features of chair elements that constructs the 3D product model of a chair from a sketch drawn by a designer. In design processes of a chair a designer usually wants to express his/her idea of the form and structure of a chair by drawing sketches because sketching is one of the most desired manners for expressing designer ide...

Communication is a central activity in command and control. However, analysing communication using linear transcription of large amounts of sequential data is tedious and time consuming. This paper describes an alternative approach for communication analysis based on visual exploration of abstract representations of communication. It introduces a visualisation technique based on the Attribute Expl... View full abstract»

We describe a paradigm for visualising time dependent flow in a network of objects connected by abstract relationships (a graph) by representing time in the third dimension. We show two variants of the paradigm, one in which the elements of the graph are shown as vertical columns of varying width and another which emphasises centrality with bending "worms". We demonstrate these techniques by visua... View full abstract»

Solving multi-goal scenario-based decision problems is difficult, especially when preferences are uncertain. Often, a mathematically sound solution is unsatisfactory due to the restricted nature of the model. This paper describes a way to visually represent these problems. The visual representation, using flower-shaped Orchid diagrams, focuses on attracting attention to the important facts without... View full abstract»

IVPrototype is an information visualization prototype for the visualization of both geometrical and non-geometrical data. Our goal is to provide a generic system that automatically generates data visualization and dynamically adapts the interface according to the data in order to control the amount of information displayed. The information is organized in one or several information groups, which a... View full abstract»
