A few weeks ago, there was a false state-wide missile alert broadcast in Hawaii. You’ve probably heard about it, because it was all over the news and the event even has its own Wikipedia page by now.
While the incident was certainly unpleasant for Hawaiians, and particularly for the poor man responsible for the broadcast, it is a stroke of luck for me. I’m always on the look-out for poor user interface design leading to catastrophe, and this event is about as good an example as it gets. In the days following the incident there was ample discussion of the user interface for sending out the broadcast (which turned out to be surprisingly difficult to reliably pin down) and how to prevent such mistakes in the future, e.g. from The Verge, Ars Technica, Jason Kottke and Nick Heer, all of which are worth a read.
As I said, I’m always looking for examples of poor user interface design, which is surprisingly difficult and seems to have become more difficult over time. By and large, the importance and necessity of good usability and user interface design seems to be so pervasive and commonly accepted that nowadays any application with a sizeable audience is well designed. While that’s obviously a very good thing for most people, it makes it quite difficult for me to find examples illustrating bad design and its consequences.
