Challenges of Remote Participation The Dialogue ATLAS Live - S. Goldfarb2 Mary: When’s the next Muon Week? Fred: Not sure. Let me check the web site. Mary: I think it still shows last year’s dates. Fred: Where is it, anyway? Google does not show a thing. I thought I had a bookmark. Mary: Never mind. Did you see the article in the Times on the SUSY announcement? Fred: Yes. I would have liked to have seen our spokesperson’s speech. I see there was a special EVO meeting, but I did not see the announcement until this morning. Mary: Why doesn’t anyone at CERN ever let us know. Fred: I guess we are not on the right e-groups. Mary: When’s the next Muon Week? Fred: Not sure. Let me check the web site.

The Problems Difficulty to find / maintain current information on the web Unaware of breaking events, important news item

Challenges of Education & Outreach The Dialogue ATLAS Live - S. Goldfarb3 Emily: What’s this LHC stuff all about? Jake: I think they are trying to make a black hole or a big bang or something. Emily: I saw a video on YouTube. It was a rap. Are you sure it’s not a new group? Jake: No. Our teacher showed us some videos on their web site a few years ago. Pretty cool stuff about smashing particles. I wonder if it’s still working. Emily: Do you remember the URL? Jake: I might have a bookmark, somewhere. I doubt they have anything new, though. Emily: I heard they found some chick named Susie. Jake: Must have been hiding in the tunnel. Emily: What’s this LHC stuff all about?

Project Status Pilot Launched This January Set Up Development & Webcasting Centre Created Three Diverse Channels of Content Variety of Content Type and Format Evaluation at End of Year Feedback Primarily Additions to Content Very Few Subtractions Some Concern Over What is Shown in Public “It really hits people over the head…” Institutes Interested in Streams with Their Own Content Departmental Announcements, Specific Features on Their Group Useful for Student Interest, Funding Agency Visits ATLAS Live - S.

Current Activities Development & Design Increased Automation via Scripts Templates Common Content Themes Data Entrance for Non-Experts (e.g. Secretarial Announcements) Single Source for Information Interfaces Same Announcements on Web, E-Group, Video Stream Content Management System?
