Software Engineering and Architectures
for Realtime Interactive Systems

SEARIS 2009 2th Workshop on IEEE VR

Description

SEARIS provides a forum for researchers and practitioners working on the design, development, and support of realtime interactive systems which span from VR, AR, and MR environments to novel Human-Computer-Interaction systems and entertainment applications. After a successful initial SEARIS workshop in 2008, this first follow-up proceeds to establish a sustainable community shaping a common understanding, deriving common paradigms, developing useful and necessary methods and techniques, and fostering new ideas.

Various hot-topics have been identified from the current scientific discussion and will be presented and discussed in different panels. Panelists will have the opportunity to present short statements on these topics and discuss them with the other participants. This format will allow us to develop a deeper understanding of detailed technical issues and to compare existing approaches with regard to specific questions and issues.

This year's workshop builds on our previous experiences at SEARIS 2008 and fosters an interactive, discussion-like exchange format as opposed to rather traditional paper presentations. We hope it will become a lively discussion with fruitful interaction between presenters and audience.

Description

SEARIS provides a forum for researchers and practitioners working on the design, development, and support of realtime interactive systems which span from VR, AR, and MR environments to novel Human-Computer-Interaction systems and entertainment applications. After a successful initial SEARIS workshop in 2008 [1], this first follow-up proceeds to establish a sustainable community shaping a common understanding, deriving common paradigms, developing useful and necessary methods and techniques, and fostering new ideas.

This year's workshop builds on our previous experiences at SEARIS 2008 and fosters an interactive, discussion-like exchange format as opposed to rather traditional paper presentations.

Various hot-topics have been identified from the current scientific discussion and will be presented and discussed in different panels. Panelists will have the opportunity to present short statements on these topics and discuss them with the other participants. This format will allow us to develop a deeper understanding of detailed technical issues and to compare existing approaches with regard to specific questions and issues.

The following main categories and related topics will be of special interest:

  • Basic Concepts: data-flow-oriented, object-oriented, component-based, scene graph(s), etc.
  • Abstraction: entity centered design, world descriptions, semantic modeling
  • Reusability/Extensibility: plugins, components, modules, extension points, etc.
  • Programming: class libraries, scripting languages, declarative languages
  • Architectural Issues: operating systems, platform independence, 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.
  • For the SEARIS 2009 full day workshop, accepted authors will expose their contributions to a specific subject in one of several panels. Authors may submit contributions to several topics, and they will present in the ones that were accepted by the committee. During the panel we will encourage the active participation of the audience, in order to concentrate and enlighten the discussion. This includes active feedback to the speakers where to concentrate and where to speed up. Besides these main panels we will have a poster session with presentations which show a compact overview on systems and their architecture. We expect this structure to provide more focused discussions and a lively environment.

The target audience includes researchers and developers from VR/AR as well as from technically close fields like ambient/pervasive computing and - of course - the computer games community.
