This book deals with the conceptual, constructive, and design-related questions of realizing user- and application-oriented interactive computer systems. Building on the volume Software Ergonomics, which analytically addresses theories, models, and criteria of interactive systems, this second volume now covers the fundamentals and extensively discusses concepts, architectures, and components that are essential for the construction of multimedia interactive systems. Interaction design models and shapes, thus forming the basis for subsequent implementation. Due to its abstraction from certain technologies, it is a task for computer scientists and designers. This creates a productive connection that translates the conceivable into the feasible. Interaction design bridges the challenging gap from analysis to implementation.
