I don’t know who recommended this book but I definitely owe them a coffee.

This is my review of The Design of Everyday Things by Donald A Norman.

Donald Norman is a cognitive scientist and usability engineer. Despite the unusual field of study, this book is one of the most informative and eye-opening works I have ever read. You’ll never look at any man-made device the same again, promise.

Have you ever tried using a new device- a new Samsung phone after a series of Nokias, iOS after Windows, hell, even a can opener- and chastised yourself for being technology illiterate? In reality, every mis-click that causes you to lose data  is a design flaw, and not the user’s fault. By definition, all gadgets are intended to make the user’s life simpler, not more complex.

The book is perhaps intended to be a textbook, but is light enough to be casual reading for a layperson. However, several basic concepts are defined fairly rigorously- I had to read a chapter or two twice. It was first published in the 1980s, so there are several charmingly outdated examples related to landline telephones. It hasn’t aged well, but the examples aren’t completely obsolete so they put the ideas across effectively enough.

5/5 from me. Read this if you are in the mood to learn something new, and aren’t intimidated by mild technology/engineering jargon.

Here are some takeaways from the book that really stuck with me:

  • Read The Fucking Manual is excellent advice, but an ideal design should be intuitive enough for someone to use it straight out of the box. A good metric to judge how intuitive controls are is to look at the mapping between the control and the function. Do you have 3 buttons for a dozen functions? Chances are, the average dad is going to have a hard time. Are the controls at least vaguely reminiscent of the functions they’re for? An example of this would be pushing a joystick forward or up to make your virtual vehicle move faster.

 

  • Norman Doors: This is a example of poor design. It refers to those annoying doors that say PUSH and PULL on them because it’s not immediately obvious what you are supposed to do without trial and error. A better alternative is illustrated in the header image for this post. Simple and effective.

 

  • Repeat after me: The Customer is King. Usability studies are essential to make sure that a) functions are intuitive and b) basic errors in judgement do not have catastrophic consequences. For instance, Norman noticed that this book was being shelved under psychology, which was slightly misleading. Switching it to design/engineering ensured that it was accessible to the right customers. Another example was the positioning of a ‘clear all’ key on a calculator in the spot usually occupied by the Return key. Experienced typists kept mashing this key at the end of a long equation, erasing all their work.
