This book gathers the latest experiences of experts, research teams, and leading organisations involved in computer-aided design of user-interactive applications supported by software. Attention is paid specifically to platform-independent user interfaces, and context-sensitive or aware applications. This includes innovative model-based and agent-based approaches, code-generators, model editors, task animators, translators, checkers, advice-giving systems, and systems for graphical user interfaces. This volume will be of interest to software development practitioners and researchers whose work involves human-computer interaction, design of user interfaces, frameworks for computer-aided design, formal and semi-formal methods, web services and multimedia systems, interactive applications, and graphical user and multi-user interfaces.
