Exam 2, CS 3205, Spring 2017
(Version 1. Last updated: April 6, 11am.)
- Exam 2 will be given in class on Thursday,
- It will be designed to be a 75 minute exam, closed book and no
- Students who have registered with SDAC to take the exam under
different circumstances should contact me to make arrangements by noon, Monday, April 10/
- Important: If an emergency causes you to unexpectedly miss the
to be late, contact the instructor by phone or email immediately or
as soon as possible! Do not delay!
The exam will be closed-book and no notes. It will be a mix of short
answer and "writing questions",
but it is likely that many of the questions will be concept or writing
Important: As noted early in the class, part of your score
will be based on how well you express your
answers using the vocabulary and terminology as defined in HCI. For
example, you may identify and describe a usability
problem but not in the way that someone trained in HCI would
talk about it -- you will not get full credit
in this case.
What's covered: Here are the readings
and slides that the exam will cover.
Readings from the ID-book textbook
(in the order studied in class):
- Ch. 2 in published ID-book.
- Ch. 11 in published ID-book, “Design, Prototyping, and
Construction.” (Ch. 10 in our eBook)
- Ch. 13 in published ID-book, “Introducing
Evaluation.” (Ch. 12 in our eBook)
- Not covered in class, but read on your own for the exam:
Chapter 12 in published ID-Book, "Interaction Design in
Practice. (Ch. 11 in our eBook.)
- Paper: “Supporting Elementary-Age Children’s
Searching and Browsing”
You do not have to read the section "Results: Simple Study" which
starts on page 18 and ends on page 29; this is a detailed statistical
analysis that's beyond what we expect in this course. But do read
the sections following that. One goal for reading this paper is to see
a good example of how an evaluation study is carried out.

Below is an overview of topics from slides (only).
Unit 3: Conceptual Models
- Readings: ID Book, Chap.
- Slide sets: cs3205-3-conc-mental-models.pdf
- Conceptual models: how
users understand all or part of a system. What one might be based on.
- The four types of
conceptual models based on activities.
- Examples covered in the
slides and class.
- Why some conceptual models
or metaphors support certain usability goals, why they might fail or
not fit certain users as well.
- Metaphors as more specific
(or fine-grained) components in a user interface. Examples discussed in
class. Why some fail.
- Interaction mode or
- General concepts, characteristics, purpose, roles, types
- Using prototypes in a ID process
- Over time in process: number of prototypes, amount of work (or
fidelity or detail) in a given prototype
- Prototyping techniques:
- Low-fidelity vs. high-fidelity
- Parallel prototyping: why quantity etc matters more than serial
refinement; functional fixation;
- Particular techniques: story-boarding; video prototyping;
paper-prototyping; wire-frames; UI flow diagrams (web site-maps); hi-fi
mockups; wizard-of-Oz. (Nothing on content diagrams)
- For these, know what they are, strengths, role, limitations
- Lots of terms and definitions -- see slides
- User evaluation technique (13.3.1 in book, described in slides)
- Roles of people involved
- General steps involved in carrying out a single session
- Think-aloud protocol AKA cooperative evaluation technique; what
the facilitator and participant do.
- Task descriptions
- Role of video, other observations
- General ideas of industry use of usability labs
- Analysis of usability defects
- Informed consent and participant rights
- Experimental design and usability: good research questions;
- Pitfalls and how to avoid them
