SEARIS provides a forum for researchers and practitioners working on the design, development, and support of realtime interactive systems (RIS). These systems span from Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) environments to novel Human-Computer Interaction systems (such as multimodal or multitouch architectures) and entertainment applications in general. Their common principle is a strong user centric orientation which requires real-time processing of simulation aspects as well as input/output events according to perceptual constraints. Therefore, we encourage researchers and developers of real-time human computer interaction systems of all flavors to share their experiences and learn from each other during this workshop. The upcoming workshop will again feature Personally Inspiring Publications as an interesting new form of contribution, see next section for details. 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, declarativity
• 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.
