Yesterday I finished reading “The Design of Everyday Things” by Don Norman (from Nielsen Norman Group) and straight from the beginning I have to say it was really educative, exceptional and informative book.
“The appearance of the device must provide the critical clues required for its proper operation.”
Don Norman
Although Don Norman is giving lots of excellent examples of good and bad design throughout the book – poorly designed doors, taps, telephones, cars, wrist watches etc – the book is rather about how people thing and are using various devices, rather about the basics of interaction between the user and the device. The book helped me to realize what makes good design good and bad design bad, how is important to design for the common user and how good design can make our lives better. That the design is not just aesthetics and that products shouldn’t be designed in isolation.
- we should blame designers for creation of difficult-to-use devices
- what affordance is and why it is so important
- crucial role of feedback and visibility in design – the user should know what to do and what’s going on
- conceptual models – what the device can do, conceptual model, system model and interface model
- how knowledge is important and how is important to divide knowledge between the world and our head
- importance of constraints and forcing functions
- understand errors, how to prevent them, how to minimise the implications and how to help the user to fix them
- conflict between the device (which the designers are familiar with) and the task (which the user is familiar with)

DOET was simply great source of knowledge and inspiration, especially now, when I just recently started to learning more about interaction and user experience design and when I’m preparing my Graphic Design in context of User Experience presentation.
