Design of Everyday Things
Donald Norman
Summary:
The chapter talks about mishaps users can have. These are slips and mistakes. A slip is an accidental move or action while a mistake leads to the wrong goal state. Slips are minor while mistakes are major. The chapter then tends to describe different types of slips such as errors due to capture, description, data, action, and modes. These are easy to detect but only when given feedback. It is possible to learn from common slips to incorporate into a future product or version. It then describes the human thought of decisions and different types of decisions. From shallow to deep to narrow. It begins talking about the human subconscious and how many of the tasks we perform are controlled by it but that we connot solve problems using it. The author gives the example of tic-tac-toe and the 1-9 number game. It illustrates how it is difficult to play this in our heads. The chapter closes by discussing issues with errors and how to confront them.
Discussion:
It was amusing reading about the errors and complexity of decision making. I had never noticed how easy it is to slip up and how the mind and state of thought is connected with it.
