One of the most annoying things that drives me crazy is how frustrating it is to use and deal with printers. For instance, the interfaces on our printers on campus are unnavigable. Simple things, such as wanting to print double-sided, have to be queued from the computer and cannot be changed at all in the printer interface. When the printers run out of paper, they simply error out but do not attempt to reprint once you add more paper. In my opinion, printers should not delete jobs from the print queue until they have been successfully confirmed to have been printed.
I think responsive designs, such as feedback mechanisms as mentioned in the reading, are important for giving users an intuitive sense of how a system will react to their input. For instance, when programming a site, on-hover CSS effects are incredibly helpful for users to understand when an element is clickable. Other techniques, such as user testing, are also crucial, where you watch people use the systems you build. If a user is not able to intuitively figure out how to use something I built, I usually take it as a sign that it’s not as simple as I had originally thought, and that it likely needs to be redesigned.
