Reading "The design of everday things" will change your life

Some month ago, I read a tweet from @oschoen, about the book "The Design of Everyday Things" from Donald A. Norman stating that reading this book (quote:) "will ruin your ability to walk through doors without complaining". I wondered why, and started reading.

Now some month later, after reading the book, I know what @oschoen meant.
Just visited the office of a law firm. Very stylish office design, but even people working there for some time do not know how to operate the doors of the wardrobe. And that is only one example. Doors that give no clues about how to use them, or even worse, give misleading cues. Taps that win design prices but until you know how they work, you always have to fiddle around with them for some time.

To make it worse, there are catastrophes that happen because of the bad design of switches or other things needed to operate power plants, trains, airplanes or whatever. And people feeling bad about themselfes not understanding how things work, instead of blaming the designer who built them.

Everybody designing products, mobile or PC applications and web interfaces should give this book a try.
