Book Reading #21 - Design of Everyday Things

Chapter 7: User-Centered Design

Summary
Dan Norman discusses  seven principles that aid in the conversion from complex tasks to more simple ones:

1. Use knowledge in the world and the head
2. Simplify structure
3. Make things visible
4. Get the mappings right
5. Exploit constraints
6. Design for error
7. Standardize

In addition to discussing the advantages and disadvantages of each principle, the author talks about making certain things difficult so that they can only be operated by experienced users.

Discussion
I thought this chapter was a little redundant as some of the design principles have been discussed before
