- The exam consists of nine questions on two numbered pages. Be sure that
you have both pages and that all questions are legible.
- Read all questions and their instructions thoroughly before you begin.
It is always worth your time to plan ahead!
- You have been given four blank pages. Use these sheets for your exam
answers. Be sure to write your name on each sheet.
- All questions are of the same value. Use this information as you budget
your time across the exam period.
- Please keep the exam questions when you are done, and submit only your
- Points will be awarded based on your explicit answers. Partial credit
will be given where possible, so show all of your work.
- The exam lasts fifty minutes. It is due at 10:50 AM.
- Shneiderman uses five measurable human factors as one standard for
evaluating user interfaces. Briefly (one sentence each) describe three
of the five measurable factors, and explain why these factors are so
important in the evaluation of user interfaces.
- You have just joined Jane McMurdock's staff as a technical specialist, and
she has assigned you to the Killer Robot case. Your first task is to
develop a list of at least three criteria that McMurdock can use to decide
whether a computer programmer should be held accountable for the negative
outcome of a program's execution. Each criterion, if partially or
completely satisfied, must indicate that a particular programmer should be
held accountable in some way.
- In Designing the User Interface, you read about Smith and Mosier's
five high-level objectives for data display. Briefly (one sentence each)
describe these objectives.
- Two of Shneiderman's 'golden rules' of interface design are "Design
dialogs to yield closure." and "Support internal locus of control."
Explain what these rules mean, give an example of each, and explain why
Shneiderman considers them golden rules.
- Both the LUCID development methodology and Kent Beck's Early Development
patterns emphasize the importance of participatory design. Identify the
motivations for doing participatory design, and then briefly describe two
kinds of prototype that Beck proposes one can develop through this approach.
- Experience has shown that three "pillars of design" help user-interface
designs create better interfaces better. Identify each pillar and
describe the role it plays in the design process.
- For what kinds of systems is the Model-View-Controller pattern a useful
technique for designing interfaces? What advantages does MVC offer in
such systems, and what costs does it impose?
- "Resolved: accidental death caused by poorly-programmed software is
analogous to accidental death caused by firearm and should be treated
similarly under the law." In one paragraph, outline an argument--pro or
con--on this resolution.
- Read the scenario below. Based on your
study of the ACM Code of Ethics and your in-class discussions of ethics,
outline the ethical issues involved in this story. Should Dianne refuse
to build the system as requested by the client?
