Natural language dialogue systems are ideal interfaces to personal digital assistants (PDAs) or other handheld clients. We explore more fine-grained co-ordination of multimodal presentations as answers to natural language questions about a specific domain by graph-based visualisation and navigation in ontological RDF result structures. Semantic Navigation on mobile devices leverages graphical user interface activity for dialogical interaction in mobile environments. Constraint-based programming helps to find optimised multimedia graph visualisations.Mon Jul 07 13:47:29 CEST 2008Proceedings of the IEEE91327-1354Speech-Gesture Driven Multimodal Interfaces for Crisis Management912003spatial multimodal 3d ai paper ieee language v0805 information crisis management processing graphics interface Emergency response requires strategic assessment of risks, decisions, and communications that are time critical while requiring teams of individuals to have fast access to large volumes of complex information and technologies that enable tightly coordinated work. The access to this information by crisis management teams in emergency operations centers can be facilitated through various human-computer interfaces. Unfortunately, these interfaces are hard to use, require extensive training, and often impede rather than support teamwork. Dialogue-enabled devices, based on natural, multimodal interfaces, have the potential of making a variety of information technology tools accessible during crisis management. This paper establishes the importance of multimodal interfaces in various aspects of crisis management and explores many issues in realizing successful speech-gesture driven, dialogue-enabled interfaces for crisis management. This paper is organized in five parts. The first part discusses the needs of crisis management that can be potentially met by the development of appropriate interfaces. The second part discusses the issues related to the design and development of multimodal interfaces in the context of crisis management. The third part discusses the state of the art in both the theories and practices involving these human-computer interfaces. In particular, it describes the evolution and implementation details of two representative systems, Crisis Management (XISM) and Dialog Assisted Visual Environment for Geoinformation (DAVE/spl I.bar/G). The fourth part speculates on the short-term and long-term research directions that will help addressing the outstanding challenges in interfaces that support dialogue and collaboration. Finally, the fifth part concludes the paper.Mon Jul 07 13:47:29 CEST 2008Proceedings of the Sixth IEEE Workshop on Applications of Computer Vision (WACV 2002)203-207Multimodal human-computer interaction for crisis management systems2002ieee interface spatial management paper processing language 3d information graphics crisis v0805 ai multimodal This paper presents a multimodal crisis management system (XISM). It employs processing of natural gesture and speech commands elicited by a user to efficiently manage complex dynamic emergency scenarios on a large display. The developed prototype system demonstrates the means of incorporating unconstrained free-hand gestures and speech in a real-time interactive interface. This paper provides insights into the design aspects of the XISM system. In particular, it addresses the issues of extraction and fusion of gesture and speech modalities to allow more natural interactive behavior. Performance characteristics of the current prototype and considerations for future work are discussed. A series of studies indicated positive response with respect to ease of interacting with the current system.Thu Jun 19 17:35:00 CEST 2008Computers and GraphicsFebruary175--88Gentropy: Evolutionary 2{D} Texture Generation262002algorithms, textures, Evolution, genetic graphics programming, Procedural Gentropy is a genetic programming system that evolves two-dimensional procedural textures. It synthesizes textures by combining mathematical and image manipulation functions into formulas. A formula can be re-evaluated with arbitrary texture-space coordinates, to generate a new portion of the texture in texture space. Most evolutionary art programs are interactive, and require the user to repeatedly choose the best images from a displayed generation. Gentropy uses an unsupervised approach, where one or more target texture image are supplied to the system, and represent the desired texture features, such as colour, shape and smoothness (contrast). Then, Gentropy evolves textures independent of any further user involvement. The evolved texture will not be identical to the target texture, but rather, will exhibit characteristics similar to it. When more than one texture is supplied as a target, multiobjective feature analysis is performed. These feature tests may be combined and given different priorities during evaluation. It is therefore possible to use several target images, each with its own fitness function measuring particular visual characteristics. Gentropy also permits the use of multiple subpopulations, each of which may use its own texture evaluation criteria and target texture.Thu Jun 19 17:35:00 CEST 2008Soft ComputingSpecial Issue.

Indeed, the growth in the computing power of these graphics cards is now several orders of magnitude greater than the growth in the power of computer processor units. Thus these graphics cards are now beginning to be used by the scientific community as low cost, high performance computing platforms. Traditional genetic programming is a highly computer intensive algorithm but due to its parallel nature it can be distributed over multiple processors to increase the speed of the algorithm considerably. This is not applicable for single processor architectures but graphics cards provide a mechanism for developing a data parallel implementation of genetic programming. In this paper we will describe the technique of general purpose computing using graphics cards and how to extend this technique to genetic programming. We will demonstrate the improvement in the performance of genetic programming on single processor architectures which can be achieved by harnessing the computing power of these next generation graphics cards.Thu Jun 19 17:35:00 CEST 2008Connection Science2 and 3325--354Towards Automated Artificial Evolution for Computer-generated Images61994(ANN), algorithms, neural networks graphics computer programming, genetic simulated evolution, artificial In 1991, Karl Sims presented work on artificial evolution in which he used genetic algorithms to evolve complex structures for use in computer generated images and animations. The evolution of the computer generated images progressed from simple, randomly generated shapes to interesting images which the users interactively created. The evolution advanced under the constant guidance and supervision of the user. This paper describes attempts to automate the process of image evolution through the use of artificial neural networks. The central objective of this study is to learn the user's preferences, and to apply this knowledge to evolve aesthetically pleasing images which are similar to those evolved through interactive sessions with the user. This paper presents a detailed analysis of both the shortcomings and successes encountered in the use of five artificial neural network architectures. Further possibilities for improving the performance of a fully automated system are also discussed.Wed Apr 23 22:05:04 CEST 2008Signal ProcessingJan153--58Shape interpolation using Fourier descriptors with application to animation graphics41982graphics Animation Wed Apr 23 14:55:19 CEST 2008Computational Statistics \& Data AnalysisAug4471--494User interaction at various levels of data displays432003graphics manipulation Direct 28Wed Apr 23 14:55:19 CEST 2008Computational Statistics \& Data AnalysisAug4423--444GGobi: evolving from XGobi into an extensible framework for interactive data visualization432003graphics Statistical 28Mon Apr 21 22:02:42 CEST 2008Journal of EconometricsAug2287--302Double bootstrap for shrinkage estimators681995Graphics Thu Mar 20 21:14:41 CET 2008New YorkVisualization: The Second Computer Revolution1989Computer graphics Sun Sep 23 16:51:18 CEST 2007AprilUS Patent 7,210,095Techniques for binding scalable vector graphics to associated information (US Patent 7,210,095)2007representation knowledge graphics software patent vector scalabe my Techniques for providing information about an object through a graphical interface include providing in a document scalable vector graphics (SVG) statements associated with a graphical representation of the object. The SVG statements are bound to a pointer to a resource that includes information pertaining to the object. The pointer to the resource associated with the SVG statements may then be extracted from the document. Information is then retrieved from the resource based on the pointer. The SVG statements may then be modified based on the information. Then a second graphical representation of the object is presented based on the SVG statements after the modifying. The presentation provides information, or control, or both, for the object.Tue Aug 21 08:14:17 CEST 2007ACM Transactions on Graphics (SIGGRAPH 2007)3Scene Completion Using Millions of Photographs262007graphics completion photograph scene What can you do with a million images? In this paper we present a new image completion algorithm powered by a huge database of photographs gathered from the Web. The algorithm patches up holes in images by finding similar image regions in the database that are not only seamless but also semantically valid. Our chief insight is that while the space of images is effectively infinite, the space of semantically differentiable scenes is actually not that large. For many image completion tasks we are able to find similar scenes which contain image fragments that will convincingly complete the image. Our algorithm is entirely data-driven, requiring no annotations or labelling by the user. Unlike existing image completion methods, our algorithm can generate a diverse set of image completions and we allow users to select among them. We demonstrate the superiority of our algorithm over existing image completion approaches.graphicsCommunity for tag(s) graphics
