Purpose
In this individual assignment you will share some of your favorite exs of good and bad interfaces or interaction design and apply good designing concepts to those exs. 
What to do 
A. Read Notes on Norman's design principles
B. Find and analyze some exs 
1. Find an ex of an interface feature that you especially like, and another ex of one that causes you problems. 
2. Analyze these exs in terms of Norman's design principles (visibility, feedback, constraints, mapping, consistency, affordance) and/or Nielsen's usablity principles (see page 27 of text). Which principles did your good ex follow? Which principles did the bad ex violate? 
Now skim through Smith & Mosier's design rules at http://hcibib.org/sam/. Can you find 
3. A good interface that violates one of their guidelines? 
4. A bad ex that followed one of these principles, but should not have done so? 
C. Make a web page describing your exs 
• prepare up your analysis: one paragraph per ex. Remember that this is a writing intensive course, so the writing will be evaluated. Give a coherent argument describeing your judgment. What guideline was followed or violated? Why was the interface more usable or less usable as a result? prepare professionally, as if you were making a report for a client or your boss. 
• Make screen dumps or take digital images of your exs, as appropriate. Please use GIF or JPG formats so that they can be viewed on any platform. 
• Put the images and your analysis in a web page on your UH ITS account web site (or your own server if you have one) with the paragraph of analysis.
