SEARIS wants to account the state-of-the-art in software design and software engineering for realtime interactive systems, to shape a common understanding, to compare systems and approaches and derive common paradigms, to develop useful and necessary methods and techniques, and to foster new ideas. Topics of interest include (but are not limited to): · Architectures: data-flow-oriented, object-oriented, component-based, scene graph(s), etc. · Abstraction mechanisms: entity centered design, world descriptions, semantic modeling · Reusability/Extensibility: plugins, components, modules, extension points, etc. · RIS Programming: class libraries, scripting & core implementation languages, declarative languages and solutions · System Issues: operating systems, portability, networking, distribution, etc. · Adaptivity: support of configurability, personalization, adaptation · Behavior: support and integration of behavioral components (physics, AI, etc.) · Implementation and Testing of Realtime Interactive Systems · Performance: consideration of evaluation strategies, latency, synchronization, etc.
