This includes: innovative model-based and agent-based approaches, code-generators, model editors, task animators, translators, checkers, advice-giving systems and systems for graphical and multimodal user interfaces. It also addresses User Interface Description Languages. This books attempts to emphasize the software tool support for designing user interfaces and their underlying languages and methods, beyond traditional development environments offered by the market. It 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.
