As enablers of online conversations between businesses and customers, Web forms are often responsible for gathering critical information—email addresses for continued communications, mailing addresses for product shipments, and billing information for payment processing to name just a few. So it shouldn’t come as much of a surprise that one of the most common questions I get asked about Web form design is: “How do I deal with international addresses?”
But before we get into the nuances of address variations, it’s worth pointing out that addresses have a commonly understood structure.

Please note that our ad-hoc test setup didn’t resemble real-world conditions. Since I had to properly measure saccadic activity and saccades times, I had to eliminate all elements that would force users to visually browse through the pages we used during testing.
We based our test setup on Luke Wroblewski’s article “Web Application Form Design.” Luke provided valuable insights and feedback during both our test preparation and results analysis. Thank you, Luke! Thus, we were able to subject Luke’s theories to usability testing and enrich them through the power of numeric data. Read More

The distinction between sorting and filtering blurs, because of a phenomenon I’ve called filtering by sorting, which leads to all sorts of interesting search user interface implications. Read More
