A belated week 3
We gave everyone some extra reading time to finish chapter two and start chapter three. I hope you’re all energised for the next discussion! Here are some questions to think on during your reading and your discussion with the rest of the group.
Don opens the chapter with a story about borrowing a car from a friend, who mentioned he’d need to put the car into reverse gear to be able to remove the key from the ignition—something he could never have figured out on his own. In another example, he discusses how people can generally use foreign coinage fairly accurately, based on the metal and relative size of the coins. These two examples demonstrate the difference between knowledge that exists in the head (we know because we’ve been told) and the knowledge that exists in the world (we can work it out based on experience), and how both of these are needed for daily functioning, although leaning more heavily on one may mean a tradeoff in the other.
- How do you feel about Don’s description of a memory burden?
- Should every stove look the same? Should design be uniform? Why? Why not?
Some questions to discuss with the rest of the group:
- As users and consumers we might often choose design aesthetics over function and simplicity of use. Why is this?
- What are some natural constraints that operate to help users to use the web environment?
- How can we use natural mapping to ease the memory load for our users in a web environment?
