Tomorrow, November 13th, is World Usability Day. It's sponsored by UPA. Transportation is this year's theme. Local and web-based events will take place around the world. Unfortunately, no events were listed for the Portland, Oregon area. However, the online card sorting of Canadian road and tourism signs is already available. A version is provided in English and in French. I'd be interested to find out more about how they use the results to improve the signage in multilingual Quebec.
