HI Everyone,

I think  this message has some significant points we need to be aware 
of as we collect issues related to the CAP work we will take up again.

Cheers,
Rex

>The User Experience of Warnings in EAS
>May 8th, 2008

>In the runup to the May 19th EAS Showdow um Summit in Washington, 
>DC, most of the discussion has focused on the nuts and bolts of 
>moving the nations broadcast alerts across digital networks based 
>on CAP.
>
>But CAP only defines the information payload of a warning. It 
>doesnt specify how that information should be presented over HD 
>radio, digital TV, computers, PDAs, digital signage or any of our 
>various other windows into the infosphere.

>This is going to become a crucial question in the very near future, 
>I think. As digitization drives broadcast content onto ever more 
>diverse platforms were going to need to give these 
>presentation/user interface issues as much attention as we have to 
>transport/relay-network design.
>
>We may want to develop some common elements consistent visual, 
>aural, even tactile (e.g., portable device vibrator cadences) cues 
>that one might almost call branding elements to ensure that 
>emergency alerts have a degree of consistency across all media. 
>Otherwise we risk letting diversity deteriorate into confusion.

>The Australians have made an interesting foray in that direction 
>with their Standard Emergency Warning Signal (SEWS) basically a 
>standard sounder that can be used consistently over broadcast, 
>wireless, wireline and even acoustical (siren and public address) 
>delivery systems. However they havent tried yet to set a comparable 
>standard in the visual or other domains.

>Last year the FCCs cellular alerting advisory committee (the 
>CMSAAC) took a few first steps toward designing a consistent user 
>experience for a basic text-messaging interface.

>But as we start talking about digital television and HD radio and 
>the things that lie beyond them, were going to need to bring some 
>real world-class user-interface expertise to bear alongside our 
>enormous pool of transmission engineering experience.

>The Common Alerting Protocol (CAP) provides a rich standard data 
>payload that can be presented hopefully consistently over all 
>media, broadcast and otherwise. But the details of how best to 
>present that richer message are still to be determined and require 
>immediate skilled attention.
