The term “haptics” refers to the science of sensing and manipulation through touch. Multiple disciplines such as biomechanics, psychophysics, robotics, neuroscience, and software engineering converge to support haptics, and generally, haptic research is done by three communities: the robotics community, the human computer interface community, and the virtual reality community.This book is different from any other book that has looked at haptics. The authors treat haptics as a new medium rather than just a domain within one of the above areas. They describe human haptic perception and interfaces and present fundamentals in haptic rendering and modeling in virtual environments. Diverse software architectures for standalone and networked haptic systems are explained, and the authors demonstrate the vast application spectrum of this emerging technology along with its accompanying trends. The primary objective is to provide a comprehensive overview and a practical understanding of haptic technologies. An appreciation of the close relationship between the wide range of disciplines that constitute a haptic system is a key principle towards being able to build successful collaborative haptic environments.Structured as a reference to allow for fast accommodation of the issues concerned, this book is intended for researchers interested in studying touch and force feedback for use in technological multimedia systems in computer science, electrical engineering, or other related disciplines. With its novel approach, it paves the way for exploring research trends and challenges in such fields as interpersonal communication, games, or military applications.

Dieses Buch bietet eine fundierte Einführung in die Technologien, die Java (JDK 1.2) sowie den Erweiterungen dieser Sprache zugrundeliegen. Um ein tiefgehendes Verständnis zu ermöglichen, werden die Paradigmen des objektorientierten Programmierens sowie die Wiederverwendbarkeit von Softwarekomponenten erläutert. Ein besonderes Anliegen des Buchs ist die Erklärung der Zusammenhänge der verschiedenen Komponenten. Die Autoren zeigen an Beispielen, wie Java verwendet werden kann, und wie verschiedene Komponenten kombiniert werden müssen, um eine Gesamtanwendung zu implementieren. Das Buch behandelt daher neben allgemeinen Aspekten der Sprache Java (AWT, Networking und Security, Internationalisierung) auch Swing, JavaBeans, JDBC, RMI, Corba und Servlets. Dem Buch liegt eine CD-ROM bei, die eine HTML-Version des Texts, Applets und die Quelldateien aller Beispiele enthält.

In this book several concepts with respect to the development and reusability of multimedia content in web-based learning systems are introduced. More specifically, the development of a component-based framework that enables developers to employ reusable software components enhanced with metadata, creating complete instructional visualizations for a given subject and integrating these visualizations in an appropriate learning context, is discussed. Two activities for making stand-alone visualizations group-aware are addressed: transparent sharing of the same instructional visualization with diverse views in a moderated session, and organization of interactions in the shared workspace. No other work has addressed the issue of transparent collaboration based on instructional visualizations enhanced with metadata in such a way.
