I have always thought some things could’ve been simpler. At times, I have had the thought that I was “dumb” for not being able to figure out how to use everyday appliances, but that’s not true. In this reading, Don Norman explains how the fault isn’t in the user, but in the design of things.
Something that drives me crazy is the variety of shower controls. Every time I go to a hotel or a friend’s house, the shower is always different from the one I’m used to. Some showers have two buttons for an overhead shower and a handheld one, but it’s not always clear which button controls which. I’ve even ended up soaked once because I accidentally turned on the overhead shower. You basically have to figure it out through trial and error, since there are rarely any instructions. This could be improved by creating a more universal design for shower controls, or by adding clear markings so it’s obvious what each button does.
Norman mentions feedback as a key principle of design, which is especially important in interactive media. Feedback lets users know their actions have been recognized by producing clear results. For example, an elevator button lights up when it’s pressed to show the action has been registered. In interactive media, feedback can be shown in many ways: a button changing color when clicked, a sound confirming an action, etc. Without feedback, users would feel lost or even think the system isn’t working.
