This chapter was really straightforward, and I liked how Norman explains that technology and psychology should act in interplay. I totally agree with the author, as he points out ‘big’ problems that are common for everybody. After reading this chapter, I came to the conclusion that many designers, engineers, and other people who create objects for our everyday use, sometimes forget about the importance of people. Specifically, they do not care that people are the key actors in the process of interaction with technology/objects. There are numerous examples of how I could not understand how something works, where to find information, etc. This proves a point that understanding human psychology is therefore essential to be able to produce the best products that are suitable for people.
Even though every example used in this chapter was clear, I feel that Norman looks at products that do not cause harm: a freezer, a sink, a door, etc. Only once, in the example of a wall that prevents people from falling down the stair shaft, he suggests something that is an example of a design used for humans’ well-being. I believe that HCD is a great way to ensure people’s safety. For instance, the instructions for emergency situations in case of a fire or in the cabin of the airplane. The instructions must be extremely understandable for people in general, and especially for those who cannot see well or are colorblind. But I have never seen those instructions made appropriate for this kind of audience.
