As stated elsewhere, I have a strong bias toward everyday objects in writing on design and usability. If you can't figure out an ostensibly "simple" device like a point-and-shoot cameras, you're not at fault; the designer is.

None of the articles I offer here deals with consequences quite so grave, but I cite Tognazzini's analysis as an object lesson in taking usability of everyday objects seriously. Some of my own articles to consider:

I've written sample usability analyses of other sites: My approach in usability analysis is to simply attempt to perform a common task, like add a review or conduct a search.

And I speak very plainly.
