Choose six of the following questions to answer.
Please provide thoughtful responses. One paragraph responses are too short, and twelve paragraph responses are likely too long. Provide answers that adequately demonstrate your understanding of the material that we have discussed throughout the semester.

1)
There are many different ways in which designers can work with a user population in an attempt to learn more about them, their goals, and how they would use a new interface. State and explain three techniques that can be used.

2)
Consider the various design principles, guidelines, and heuristics we have discussed. Create your own list that combines aspects of these principles, guidelines, and heuristics. Describe each item giving examples for each. Justify your selection of these items.

3)
There are a number of “metrics” that can be used in a usability study to judge the success of an interface. For example, the number of errors a user makes while attempting to complete tasks. For each of three different metrics that can be used to determine the usability of a product, state the metric, explain it, and give an example of it in the scope of a product. Try to choose three that are as distinct from one another as possible.

4)
When designing a form, what things should you consider and why. Give examples to support your explanation.

5)
Discuss “task centered design” and “system centered design” in a way that clearly indicates their differences. State which of the two you think is the better approach and justify your answer.

6)
What different design considerations should you make when designing for a mobile device and a desktop computer? Among other considerations be sure to discuss design needs and differences in terms of Fitts’ law.

7)
Consider the five design principles “affordance”, “visibility”, “feedback”, “constraints” and “consistency”. For each of the five, briefly explain the principle and describe an example of it being used in a good design.
