• Part 1. Discussion/short answer questions:
  • 1a. What is usability? Is it uniquely determined by the "internal" characteristics of a product or system, such as its (interface) design and implementation? If so, which specific internal characteristics? If not, what other factors also affects usability?
  • 1b. True or false? Universal usability = usability is the same for all users (across all user "universe"). Briefly justify yourself.
  • 1c. Can usability be quantified using a single metric? If so, define your single metric. If not, what are the quantitative and non-quantitative usability metrics?
  • 1d. Consulting the modified/enhanced UID process we discussed in class, outline the UI evaluation activities that can be performed before system implementation, and discuss the importance of these activities in refining/improving UI designs and design prototypes.

• Part 2. UI design/evaluation
  Select a software, an application, a Web site, an online service, a smart device, a game, or anything with computer/software embedded in it, that you may interact with as a user, and perform the following:
  • 2a. Classify the interaction style(s) of its user interface.
  • 2b. Analyze its usability by consulting the 8 golden rules of interface design.
  • 2c. How would you measure its usability? Give some examples.
    
  (Make up some numbers, if it helps).
