The Dialogue

ATLAS Live - S. Goldfarb 2

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.

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. Goldfarb 3

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.

The Problems Need to announce news items to the public Need to disseminate new educational material

ATLAS LiveA Communication Project

Assemble Multimedia Content into HD Video Streams Broadcast the Streams to Dedicated Monitors Webcast the Streams to the Internet

Primary Goals Assure a Maintained, Current Source of Relevant

Information Provide a Fast Network of Communication to Collaboration Provide a Continuous Stream of Communication to Outside

Notes Does NOT Replace Web Pages, Mailing Lists Does Provide Fast, Reliable Access to the BIG PICTURE

Project StatusPilot 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

Current ActivitiesDevelopment & 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?

Content Presentation Scheduling Television Style

Institutional Screen Pilot Tailored Content
