Chapter 3: Knowledge in the Head and in the World
Summary
Some technological designs require some type of memorization by the user. A classical example is when you start a typewriting class where after some time, you are required to type either without looking or with the keys marked off. There are many everyday activities that we perform, but when asked to explain to some else you often cannot explain well. This happens because you just do them, you know how to do the activity but do not remember precisely enough to describe it to some else with details.
Discussion
I thought of one of my work colleagues when I read this chapter, because he suffers from sleeping disorders and has to take medication every day. In order for him to perform his daily activities he has been forced by our boss to leave notes to remember things.
