Use of telepresence in informal broadcasting over the internet

摘要

It gives us great pleasure to welcome you to the 2nd ACM International Workshop on Effective Telepresence. This workshop builds upon the ACM SIGMM 2003 Workshop on Experiential Telepresence (ETP03) held in conjunction with ACM Multimedia last year. Last year's workshop and panel involved a lively debate on what the notion of an experience implies. One of the conclusions was that we are in need of models for knowledge spaces that facilitate new forms of creativity, knowledge exploration and social relationships. >We would like this workshop to facilitate a more focused debate, namely about the means of experience in the context of seamless remote interaction. While sophisticated systems for distributed collaboration and immersive presence have emerged from time to time, their acceptance has been limited. The most commonly cited problems with such systems are that they are too difficult to set up and use, and that their value is not commensurate with cost. >The challenge, then, is to develop effective telepresence systems that offer appropriate interfaces and tools to enable seamless interaction with remote people and events. This has been recognized as one of the "grand challenges" for the multimedia community. The design and measures of performance of such systems should be centred on end-user experience. The goal of this workshop is to foster a community of researchers advancing the various technical and socio-technical aspects of telepresence. This workshop aims to bring together a good mix of people from academia, industry, and government, and spanning various disciplines including the sciences, engineering, and the arts. >An event of this kind is only as good as the quality of the people it can bring together. We have been fortunate to have a diverse program committee of research leaders of the highest expertise and reputation, who showed enthusiasm and support for this workshop. Our program this year includes six papers for oral presentation and nine papers for demo presentation. Together, they should provide an excellent snapshot of the state of research today in telepresence and we hope you like this mix of presentations. We also have three special sessions - two keynote talks and a panel session - based on invitations to some world-renowned people. The keynote talks by Jaron Lanier and Duffie White, and the panel on "Directions and frameworks for effective telepresence" should go a long way in stimulating and guiding future research in this area. This year, we invited workshop participants to post questions and discussions to the workshop website starting several weeks before the workshop. We hope participants find this leading to a more interesting debate in the panel session.
