This volume contains selected papers from the 10th Interdisciplinary Workshop in Informatics and Psychology which had as its theme Cognitive Aspects in Visual Languages and Interfaces. Visual languages in general, visual programming languages in particular, and graphical or visual user interfaces are increasingly regarded as important improvements for the interaction between people and artifacts. Visual and graphical user interfaces have already a history of a number of years in terms of research and development. The focus on visual languages and visual programming languages, however, is more recent. The development of graphical user interfaces was accompanied and reinforced by psychological research but visual languages are still mainly inventions of designers and not designed on the basis of principles derived also from knowledge of psychology or other behavioral sciences.

The presentations and discussions at the workshop showed increasing interest in paradigms of visual languages and their psychological foundation. Visual languages and interfaces must be seen as means to support and enhance represention, application and processing knowledge visually. The study of the cognitive aspects in visual languages and interfaces is thus an important part of Human-Computer Interaction as a discipline "concerned with the design, evaluation and implementation of interactive computer systems for human use and with the study of major phenomena surrounding them" (definition of HCI in the ACM SIGCHI Curricula for Human-Computer Interaction). This book will stimulate future research in the area of Human-Computer Interaction and Visual Languages.

This book grants the reader a comprehensive overview of the state-of-the-art in system-level memory management (data transfer and storage) related issues for complex data-dominated real-time signal and data processing applications. The authors introduce their own system-level data transfer and storage exploration methodology for data-dominated video applications. This methodology tackles the power and area reduction cost components in the architecture for this target domain, namely the system-level busses and the background memories. For the most critical tasks in the methodology, prototype tools have been developed to reduce the design time. The approach is also very heavily application-driven which is illustrated by several realistic demonstrators, partly used as red-thread examples in the book. The quite general applicability and effectiveness has been substantiated for several industrial data-dominated applications, including H.263 video conferencing decoding and medical computer tomography (CT) back projection. To the researcher the book will serve as an excellent reference source, both for the overall description of the methodology and for the detailed descriptions of the system-level methodologies and synthesis techniques and algorithms. To the design engineers and CAD managers it offers an invaluable insight into the anticipated evolution of commercially available design tools as well as allowing them to utilize the book's concepts in their own research and development.

This book investigates the design of compilers for procedural languages, based on the algebraic laws which these languages satisfy. The particular strategy adopted is to reduce an arbitrary source program to a general normal form, capable of representing an arbitrary target machine. This is achieved by a series of normal form reduction theorems which are proved algebraically from the more basic laws. The normal form and the related reduction theorems can then be instantiated to design compilers for distinct target machines. This constitutes the main novelty of the author's approach to compilation, together with the fact that the entire process is formalised within a single and uniform semantic framework of a procedural language and its algberaic laws. Furthermore, by mechanising the approach using the OBJ3 term rewriting system it is shown that a prototype compiler is developed as a byproduct of its own proof of correctness.

Computer interfaces and documentation are notoriously difficult for any user, regardless of his or her level of experience. Advances in technology are not making applications more friendly. Introducing concepts from linguistics and language teaching, Language and Communication proposes a new approach to computer interface design. The book explains for the first time why the much hyped user-friendly interface is treated with such derision by the user community. The author argues that software and hardware designers should consider such fundamental language concepts as meaning, context, function, variety, and equivalence. She goes on to show how imagining an interface as a new language can be an invaluable design exercise, calling into question deeply held beliefs and assumptions about what users will or will not understand. Written for a wide range of computer scientists and professionals, and presuming no prior knowledge of language-related terminology, this volume is a key step in the on-going information revolution.

This book encapsulates some work done in the DIRC project concerned with trust and responsibility in socio-technical systems. It brings together a range of disciplinary approaches - computer science, sociology and software engineering - to produce a socio-technical systems perspective on the issues surrounding trust in technology in complex settings. Computer systems can only bring about their purported benefits if functionality, users and usability are central to their design and deployment. Thus, technology can only be trusted in situ and in everyday use if these issues have been brought to bear on the process of technology design, implementation and use. The studies detailed in this book analyse the ways in which trust in technology is achieved and/or worked around in everyday situations in a range of settings - including hospitals, a steelworks, a public enquiry, the financial services sector and air traffic control.

In today s world, services and data are integrated in ever new constellations, requiring the easy, flexible and scalable integration of autonomous, heterogeneous components into complex systems at any time.

Event-based architectures inherently decouple system components. Event-based components are not designed to work with specific other components in a traditional request/reply mode, but separate communication from computation through asynchronous communication mechanisms via a dedicated notification service.

Muhl, Fiege, and Pietzuch provide the reader with an in-depth description of event-based systems. They cover the complete spectrum of topics, ranging from a treatment of local event matching and distributed event forwarding algorithms, through a more practical discussion of software engineering issues raised by the event-based style, to a presentation of state-of-the-art research topics in event-based systems, such as composite event detection and security. Their presentation gives researchers a comprehensive overview of the area and lots of hints for future research. In addition, they show the power of event-based architectures in modern system design, thus encouraging professionals to exploit this technique in next generation large-scale distributed applications like information dissemination, network monitoring, enterprise application integration, or mobile systems.
