==First Workshop at OOPSLA on Software Engineering and Architectures for Realtime Interactive Systems==

The first SEARIS Workshop at OOPSLA 2009 has been accepted. Our main purpose is to spread the early results we have obtained at IEEE VR and to invite people at the OOPSLA community to participate in our discussions. 

Until now, SEARIS was hold twice at the IEEE Virtual Reality Symposium, where the primary contributions were made by the VR, AR, and MR community. With the OOPSLA edition of SEARIS we want to to account the state-of-the-art in software design, to shape a common understanding, derive common paradigms, develop useful and necessary methods and techniques, and to foster new ideas. There is no doubt that both communities have a lot in common and can benefit from each other: RIS architects to extend their knowledge required for the development of complex systems and the OOPSLA community to gain insight into highly interactive multi-modal user interfaces and dynamic virtual worlds and their hidden issues.

'''Deadlines'''
* '''Abstract Submission Deadline:''' 21st of August 2009 
* '''Paper Submission:''' 28th of August 2009 
* Notification of acceptance: 1 week before OOPSLA early reg. deadline 
* Camera-ready: 2nd of October 2009 
* Workshop: 25th/26th of October 2009 

===Description===
SEARIS provides a forum for researchers and practitioners working on the design, development, and support of realtime interactive systems which span from Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) environments to novel Human-Computer-Interaction systems and entertainment applications. SEARIS has its roots in the VR community in general and in IEEE VR in particular, where we have hosted this workshop in the last two years. This year, we would like to spread our discussion to the OOPSLA community, in order to establish a sustainable community shaping a common understanding, deriving common paradigms, developing useful and necessary methods and techniques, and fostering new ideas. We believe we can both learn from the OOPSLA community who is working in similar problems and show our early results in the VR field.

The goals for OOPSLA´s SEARIS are the following:

*Provide a common discussion venue for researchers of Realtime Interactive Systems
*Briefly describe early results from selected participants
*Discuss new ideas and results in related topics

We would like to gather researchers from both the OOPSLA and VR communities in order to discuss known problems and possible solutions in the field of Realtime Interactive Systems´ Development. it is our belief that by discussing results in both communities we could advance the state of the art in this field.

===Format===

This year's workshop builds on our previous experiences at IEEE VR SEARIS 2008 and 2009. We would like to both create a common ground of understanding and foster an interactive, discussion-like exchange format as opposed to rather traditional paper presentations.

We would like to divide our discussion in two parts: State of the art descriptions and hot topics. State of the art descriptions look for surveys on the main results in this field, which will allow our communities to understand achievements and approaches to tackle RIS issues from the OOPSLA and VR communities. Hot topics look for novel results in the field, in categories related to RIS development such as the following:

*Architectures: data-flow-oriented, object-oriented, component-based, scene graph(s), etc.
*Abstraction: entity centered design, world descriptions, semantic modeling
*Reusability/Extensibility for RIS systems: plugins, components, modules, extension points, etc.
*Programming: class libraries, scripting languages, declarative languages
*System 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.

Accepted authors for state of the art descriptions will present their ideas in a panel-like format. Accepted contributions for hot topics will be organized in at most 4 sessions. Each session will have paper presentations and a discussion panel. During panels 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. We expect this structure to provide more focused discussions and a lively environment. 

===Anticipated Attendance===

The target audience includes researchers and developers from both the OOPSLA and VR communities. This includes application developers on realtime systems, VR/AR as well as from technically close fields like ambient/pervasive computing and - of course - the computer games community. We would like to have an audience of between 20 to 60 people.

===Advertisement===

We will encourage people from our IEEE VR community to attend to OOPSLA this year. We would like the OOPSLA organization to allow us to spread our invitation to its community. We will also extend this invitation to software engineering researchers in our Universities, and by means of them to their research networks.

===Participant Preparation===

Presenters will be asked to prepare a slide presentation of about 10 minutes of the work in their accepted papers. General public of this workshop will receive in advance the workshop´s program with a set of questions, which will guide the discussion in each topic´s panel.

===Format===

This will be a full day format, with the following proposed schedule:

* Panel on state of the art descriptions: 2h
* Hot topic 1 (Papers and panel): 1h
* Hot topic 2 (Papers and panel): 1h
* Hot topic 3 (Papers and panel): 1h
* Hot topic 4 (Papers and panel): 1h

As in the workshop at IEEE VR 2009, participants will be invited to resubmit extended versions of their papers, and they will be collected in Proceedings with an ISBN from Springer - Verlag.
