We invite submissions of demonstrations for ICTD 2010. The demo session provides researchers and practitioners a venue for showcasing live demonstrations of their work. The focus of a demonstration may span novel hardware or software systems, video footage, or physical artifacts. Example demos may include interactive demos of specific tools or innovative applications of existing tools (Note: there is likely to be a separate session showing video-footage of work done, while the demo contributions should focus mainly on the technology). The exhibition of open resources and their impact in real world contexts are particularly welcome. The exhibition of open resources and their impact in real world contexts are particularly welcome. Unlike ICTD 2010 papers, the subject of a demo may have been published previously, either in ICTD or in other venues. However, the demonstration itself should be new and interesting to the ICTD community, and should reflect work that is at least as mature as a poster presentation. Demo submissions may represent research projects, commercial or not-for-profit tools, or government initiatives. Both novel projects as well as well-established systems are invited for demonstration. At the conference, all demonstrations will be presented in parallel with an interactive audience (comparable to a poster session). At least one author of each accepted demo must register for the conference and attend to present the demo. Deadline is April 30, 2010. See http://www.ictd2010.org/?page_id=409 for more.
