All six such workshops are successful examples of fruitful international cooperation under the auspices of the Eurographics working group on Multimedia. The workshop covered a wide range of subjects, from media production to content processing and delivery, with a special focus on issues related to interactive video environments. These Dcluded standards and approaches for interactive television, hypervideo, collaborative video, augmented reality, mobile multimedia, the integration of TV and the Web, content analysis, processing and presentation. The program consisted of two invited keynote presentations, eighteen technical papers and one demonstration, attracting a diverse world-wide group of thirty attendees. Technical papers were organized in six sessions spanning the two days: 3D in Multimedia, Multimedia Architectures and Authoring, \ideo and Coding, Content Based Retrieval and Security, Interactive Media and Interactive TV. The demonstration presented a multimedia system for aerobics and fitness training, exploring the combination of sound and interactive graphics in an effective manner. The keynote presentation by V. Michael Bove provided insights into new architectures for large scale pervasive computing. The second invited presentation by Glorianna Davenport discussed the relations between creativity and interactive movies as participatory art enabled by new media. An international program committee of 27 specialist experts reviewed all submissions and their recommendations were used for selecting the final papers: Ann Blandford, Middlesex Univ., UK W.

Michael Bove, Jr. MIT Media Laboratory, Cambridge MA USA {bill, vmb}~media.mit.edu,ht~://www.media.mit.edu/-vmb/obmg.html Abstract. The Object-Based Media Group at the MIT Media Labora tory is developing robust, self-organizing programming models for dense ensembles of ultra-miniaturized computing nodes which are deployed by the thousands in bulk fashion, e.g. embedded into building materi als. While such systems potentially offer almost unlimited computation for multimedia purposes, the individual devices contain tiny amounts of memory, lack explicit addresses, have wireless communication ranges only in the range of millimeters to centimeters, and are expected to fail at high rates. An unorthodox approach to handling of multimedia data is required in order to achieve useful, reliable work in such an environment. We describe the hardware and software strategies, and demonstrate sev eral examples showing the processing of images and sound in such a system. 1 Introduction We begin by observing that semiconductor process technology will shortly arrive at the point where autonomous computing elements - possibly coupled with sensing or actuating devices - can be scaled to the size of large sand grains and sold at bulk prices. It thEm will become possible to move computing out of the sort of packaging in which it is currently housed and make it part of the built environment, embedding processors in rboards, and into everyday objects such as furniture, clothing and random surfaces. As a representative embodiment, consider the architecture advanced by Sussman, Abelson and Knight [1]: ultra miniaturized computing nodes each fitted with an on board microprocessor, 50K of memory and a wireless transceiver, all shrunk down to the size of a pin head and powered parasitically. In the domain of interest, these nodes would be embedded in a 2D surface (such as the plywood in a table top) with a density on the order of tens of thousands p~r square meter. Positioning would be pseudo-random, with no local restrictions density or regularity. Once exposed to power, they should boot Oft and self organize their local address space. External I/0 would be via physical proximity with an object fitted with a transceiver whose protocols are identical to the transceivers on the chips. J. Jorge et al.
