About 9 months ago my fellow co-worker, the User Experience Designer Graham Beale, and I started developing ideas for a prototype of a new Currency Converter for the worldwide relaunch of Yahoo! Finance.
We wanted Features we haven't seen like this in the Internet so far. We wanted conversion without a page reload, searching for currencies like in the Firefox 3 "awesome bar", total accessibility, much more and of course everything in realtime.
About a year, many user tests, many new ideas, a lot of Screenreader testing with my fellow co-worker Artur Ortega and even more time developing, the result went online yesterday night!
My article about Making the new Yahoo! Currency Converter accessible is now online on the YDN Blog!
