Telepresence represents one of the most exciting and challenging areas of technology at the intersection of  computing and communications. Researchers from various fields are addressing different aspects of telepresence technologies. However, most telepresence systems including video conferencing systems have been dealing with transmitting multimodal data rather than creating effective means of experiencing remote environments and events. We would like this workshop to facilitate a new debate in multimedia on creation, archival, representation and transmission of electronic experiences. The notion of an experience implies skill, facility, practical wisdom, or insight gained by personal knowledge, feeling or action. We are in need of models for knowledge spaces that facilitate new forms of creativity, knowledge exploration and social relationships. The design and measures of performance of such experiential telepresence systems should be centered on the end user. 

This workshop will build upon the ACM SIGMM 2002 Workshop on Immersive Telepresence (ITP2002) held in conjunction with ACM Multimedia last year. Last year’s workshop and panel involved a lively debate on what really needs to be transmitted for telepresence, or what is immersive – whether more realism is the goal. One of the conclusions was that the quality of experience is of paramount importance, and that details only come next. So a significant challenge in telepresence is to assimilate data from different sources to model the experience that has to be transmitted. The goal of this workshop is to foster a community of researchers advancing the various technical and socio-technical aspects of experiential telepresence. We invite contributions from researchers in various fields addressing different aspects of this challenge. These fields include computer graphics, computer vision, human computer interaction, acoustics, signal coding and transmission, networking, and databases, to name a few. We would also strongly encourage publications from the arts (dance, music, theater, visual arts), from architecture and communications.

We encourage both regular and position papers addressing experiential telepresence including:

1. Modeling and design of experiential telepresence systems 
2. Generative models of experience
3. Multimodal sensing (including cameras/computer vision, microphone arrays/acoustics, haptic sensors, active badges etc.) 
4. Multimodal presentation and display (including projection systems, flat panels, 3D graphics, 3D audio) 
5. Smart sensors and sensor networks 
6. Context-driven representational schemes for archival and presentation (Adaptive, user-centric representation and presentation schemes, temporal models for user context)
7. Virtual and augmented reality 
8. Network design and infrastructure 
9. Semiotics and mediated systems (transcoding of semantics across different sign systems, spatio-temporal databases for storing experience and context) 
10. Formal models for interactivity and immersion in mediated systems (multimedia grammars, feedback)
11. Formal mechanisms of evaluation of experiential telepresence systems (models, user study methodologies)
12. Examples of experiential telepresence
    

Workshop Format:

This one-day workshop aims to create an atmosphere for stimulating interaction and discussion among researchers interested in Experiential Telepresence. The workshop will include oral and poster presentations by authors of accepted papers and a panel in which the panelists are several prominent leaders in this area. Workshop proceedings will be published by the ACM and made available to workshop participants. The proceedings will include accepted papers and position statements of the panelists.
