to ask you several desirable benefits
including:
Better data Written record of subject insights Development of mature perspective True involvement in the data All of the answers except for E) None of the above TERM 2
Which of the following fits the IRB definition of
subjects research?
DEFINITION 2 Studies involve human subjects to test or develop devices, products, or materials that have been developed to research for human use (A) Studies using private information that can be readily identified with individuals, even if the information is not collected specifically for the study in question. (C) TERM 3
Which of the following is a type of IRB review?
DEFINITION 3 Exempt review (A) Expedited review (C) Full board review (E) TERM 4

make up contextual inquiry?
DEFINITION 4 Work modeling (A) Interviewing (C) Consolidation (D) TERM 5

interactive systems presented in lecture?
DEFINITION 5 (E): Discover, develop, design, measure
Who was the first person to demonstrate the
illusion of direct manipulation of a digital
object?
(B): Ivan Sutherland TERM 7
Which of the following studies is linked most
directly to the establishment of the national
research act in 1974 and ultimately the
Belmont report and federal regulations for
human subject protection?
DEFINITION 7 (A): The public health service Tuskegee study of untreated syphilis in the Negro male TERM 8

Milgram's shock experiment is the most
famous example of:
DEFINITION 9 (A): Deception TERM 10
Flying a commercial plane involves the pilot
Capt. An air traffic controller interacting
together; the pilot and capt. interacting with
instruments in the cockpit, and the pilot and
Capt. interacting with the environment in
which the plane is fine. This is an example of:
DEFINITION 10 (A): Distributed cognition
Define qualitative and quantitative methods
and give an example of each method.
Quantitative: hard numerical data of a variable; measuring out 1000mL of a solutionQualitative: data that can't be given hard numerical data of a variable; the color of the same solution TERM 17
What are the advantages and disadvantages
of qualitative and quantitative methods as a
data gathering technique?
DEFINITION 17 QuantitativePros: gives us crisp numerical data that can be easily presented and summarizedCons: doesn't give us a full answer; how do we know what questions we're trying to answer?QualitativePros: Gives us full, rich answers about people and phenomenonCons: This data can be extremely hard to capture TERM 18
Contextual Inquiry is based on a set of
principles that allow it to be molded to each
situation a project encounters. List and
describe the set of principles.
DEFINITION 18 C - Context; understand the work in the context of the user's environmentP - Partnership; work with the subject to understand their workI - Interpretation; understand why subjects do things the way they do "there is no 'wrong' way to do something"F - Focus; understand the fine points of what the user is doing TERM 19
Define gulfs of execution and evaluation.
DEFINITION 19 The gulf of execution is the difference between the intentions of the users and what the system allows them to do.The gulf of evaluation is the difficulty of assessing the state of the system and how well the artifact supports the discovery and interpretation of that state. TERM 20
List and define the 6 principles of design
which help lead to good designs?
DEFINITION 20 Seriously learn this Affordance Mapping Constraints Visibility/Feedback Consistency Metaphors
How can a designer provide a good
conceptual model of a system?
Taking advantage of affordances and constraints. Use popularly accepted mechanics (affordance) and commonly used conventions (constraints). TERM 22
Explain what affordance is and how it can be
used in the design of an interface?
DEFINITION 22 Taking pre-existing design elements that are commonly used and accepted in other applications, and implementing them into the design of your own interface. TERM 23
List and define the four evaluation paradigms
discussed in class. List the positives and
negatives of each.
DEFINITION 23 "Quick and dirty"; quick feedback but not the most useful Usability testing; good quantitative data, but significant start-up costs Field studies/naturalistic studies; a "true" real-world test of a system, but requires fully functional system and data does not often reduce to quantitative measures Analytical evaluations; no functional system or subjects needed, but lacks context of real-world situations TERM 24
How do you create a vision?
DEFINITION 24 You write a paragraph describing the current system in place; what works about the system and where are the breakdowns? Then write a paragraph (without implementation or design details) describing a new system that would replace the old one. How would it fix the problems and measure what works. TERM 25
What are the four components that make of a
vision statement?
DEFINITION 25 Breakdowns, what works, how you will fix, how you will measure
Which of the following are considered benefits
of the coding process?
(A): Transforms us from mere viewers to analytical observers(B): Helps us understand work practices at a much deeper level(C): Reveals workarounds and habits people forget(D): Leads to quantification of the phenomena TERM 32
Which of the following is true about external
representations?
DEFINITION 32 (A): Serves the purpose of allowing us to manage complexity of the data(B): Allows themes to emerge from the data(C): Externalizes the data so that it is collectively owned(D): Breaks the initial ethnographic process of seeing data "in the small" All of the above TERM 33
Which of the following is an example of a
qualitative research method?
DEFINITION 33 (C): Contextual inquiry TERM 34
Define Horizontal, Vertical, Low Fidelity, and
High Fidelity prototypes.
DEFINITION 34 Horizontal: broad overview of a systemVertical: Detailed rendition of one small part of a systemLow-fidelity: extremely coarse approximation of system using common physical materialsHigh-fidelity: systems nearly identical to the proposed production version
