1. How did taking the position of an extreme user influence your thinking in relation to the design challenge? Was it different to how you usually generate ideas and empathy?

Extreme users might have different needs from ordinary users, which are often more harsh,and therefore cause more design challenges. And it is quite different to how I usually do especially when I cannot agree with that kind of personality and lifestyle.

2. Did any of the other design thinking techniques(design provocation card, stories, storyboards, etc.) help you to work through ideas and collaborate with your group members?

These techniques did help a lot when  generating ideas and communicating with group mates. By using design provocation cards, we came up with more ideas in different respects, while background stories help us to build a vivid figure of our users and make it easier to explain them to each other. And storyboards make our idea in a visual way and naturally understandable than word description.
