For the first time, a comprehensive collection of the latest developments in scripting and representation languages for life-like characters. The text introduces toolkits for authoring animated characters which further supports the practicality and ease of use of this new interface technology. As life-like characters is a vibrant research area, various applications have been designed and implemented. The text covers the most successful and promising applications, ranging from product presentation and student training to knowledge integration and interactive gaming. It also discusses the key challenges in the area and provides design guidelines for employing life-like characters.
Embodied conversational agents (ECAs) are autonomous software entities with human-like appearance and communication skills. These agents can take on a number of different roles, for example, as an assistant, tutor, information provider, or customer service agent. They may also simply represent or entertain a user. The precise nature and benefits of different characteristics of ECAs requires careful investigation. Questions range from the function of an eyebrow raise to mechanisms for assessing and improving ECA trustworthiness. This book will help experts and designers in the specification and development of applications incorporating ECAs. Part 1 provides guidelines for evaluation methodologies and the identification of design and evaluation parameters. Part 2 demonstrates the importance of considering the user's perspective and interaction experience. Part 3 addresses issues in fine-tuning design parameters of ECAs and verifying the perceived effect. Finally, in Part 4 lessons learned from a number of application case studies are presented. The book is intended for both ECA researchers in academia and industry, and developers and designers interested in applying the technology.
As an introduction to fundamental geometric concepts and tools needed for solving problems of a geometric nature using a computer, this book fills the gap between standard geometry books, which are primarily theoretical, and applied books on computer graphics, computer vision, or robotics that do not cover the underlying geometric concepts in detail. Gallier offers an introduction to affine, projective, computational, and Euclidean geometry, basics of differential geometry and Lie groups, and explores many of the practical applications of geometry. Some of these include computer vision, efficient communication, error correcting codes, cryptography, motion interpolation, and robot kinematics. This comprehensive text covers most of the geometric background needed for conducting research in computer graphics, geometric modeling, computer vision, and robotics and as such will be of interest to a wide audience including computer scientists, mathematicians, and engineers.
This volume contains the research papers presented at the 12th Eurographics Workshop on Computer Animation and Simulation, Manchester, UK, September 2-3, 2001. The workshop is an international forum for research in computer-animation and simulation. This year, we choose to give a special focus on the modelling and animation of complex phenomena. This includes the modelling of virtual creature- from their body-parts to the control of their behavior, and the animation of natural phenomena such as water, smoke, fire and vegetation. The call for papers required submission of the full papers for review, and each paper was reviewed by at least 2 members of the international program committee and additional reviewers. Based on the reviews, 16 papers were accepted. We added to the final program an invited talk by Jos Stam. We wish to thank all reviewers for their time and effort in working within the rigid constraints of the tight schedule, thereby making it possible to publish this volume in time for the workshop. We also thank the authors for their contributions to the workshop, without whom this unique forum for animation and simulation work would not exist.

This book constitutes the refereed proceedings of the Third International Conference on Augmented Cognition, FAC 2007, held in Beijing, China, in July 2007, within the framework of the 12th International Conference on Human-Computer Interaction, HCII 2007, with 8 other thematically similar conferences. It covers general Augmented Cognition methods and techniques and discusses various Augmented Cognition applications.
This is the second of a two-volume set that constitutes the refereed proceedings of the Second International Conference on Usability and Internationalization, UIHCII 2007, held in Beijing, China in July 2007. The papers of this second volume cover global and local user interfaces and are organized in topical sections on designing global and local products and services, as well as enhancing and personalizing the user experience.
Students explore the idea that thinking is a form of computation by learning to write simple computer programs for tasks that require thought. This book guides students through an exploration of the idea that thinking might be understood as a form of computation. Students make the connection between thinking and computing by learning to write computer programs for a variety of tasks that require thought, including solving puzzles, understanding natural language, recognizing objects in visual scenes, planning courses of action, and playing strategic games. The material is presented with minimal technicalities and is accessible to undergraduate students with no specialized knowledge or technic...
This book constitutes the refereed proceedings of the 12th International Conference on Intelligent Virtual Agents, IVA 2012, held in Santa Cruz, CA, USA, in September 2012. The 17 revised full papers presented together with 31 short papers and 18 poster papers were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on IVAs on learning environments; emotion and personality; evaluation and empirical studies; multimodal perception and expression; narrative and interactive applications; social interaction; authoring and tools; conceptual frameworks.
This is the first of a two-volume set that constitutes the refereed proceedings of the Symposium on Human Interface 2007, held in Beijing, China in July 2007. It covers design and evaluation methods and techniques, visualizing information, retrieval, searching, browsing and navigation, development methods and techniques, as well as advanced interaction technologies and techniques.
