which statement about tracking is true? - ANSWER Human performance on zero and
first order systems are nearly the same
what is the reason that changing a straight handle on a tool is to a bent handle would be
recommended - ANSWER it keeps the wrist straight (reduces ulnar deviation)
the difficulty of driving when visibility is limited by dense, thick fog, is an illustration of ...
- ANSWER the influence of preview in tracking tasks
which of these changes to a tracking task will improve performance - ANSWER A, B, C
A: if the task has a compensatory display, replace with a pursuit display
B: Increase the specificity of the displayed error
C: provide a 0.5 second preview of the input
comparing the two displays above, one is considered superior - ANSWER the scales
should be numbered by 10s, not 20s
carpal tunnel syndrome is - ANSWER injury of the median nerve where it passes through
the carpal tunnel
which theory of accident causation is the best (in terms of being the best in accounting
for the most accidents)? - ANSWER contributing factors in accident causation (CFAC)
theory
In rammasens error classification theory which... concerning errors occuring from
skill-based behavior? - ANSWER A: they result from applying the wrong rules from the
collection of stored rules which we use to respond to familiar situations
B: they are analogous to the type of errors called Slips in Norman's error classification
D: they are analogous to the type of errors called Base Rate Errors in Norman's error
classification
You are presented with the two rotary control knobs, A and B, which move a sliding
pointer on a display. For a one quarter turn of control A, the pointer moves distance A
(shown above). For a one quarter turn of control B, the pointer moves a lesser distance
B. Which control has a lower control response ratio? - ANSWER A
You ask participants to increase the setting in this display up to 20 using control C, and
you note that they all turn it clockwise. Which of these principles does not predict this
, action? - ANSWER Scale-side principle
which expression is correct - ANSWER response time = reaction time + movement time
You have the choice in your project of creating a new display for your system from the
very beginning (ie no previous designs). For one function, you have the option of
choosing a visual display or an auditory display. What are some of the conditions under
which you prefer to choose a visual display? - ANSWER the messages are long and
complex and must be referred to later
which of the following is not one of the legal requirements for an adequate warning?
Hint: an element might be good human factors, but not legally required to call the
warning adequate - ANSWER a graphic symbol
according to the design principles (by Esterby) discussed in class and in your book,
what principle makes the above graphic symbol a good symbol? - ANSWER all elements
of the symbol lie within a single boundary
In order to prevent WWII pilots from retracting their landing gears and thus damaging
their planes upon landing, control levels were redesigned using - ANSWER shape
coding
which statement is false? - ANSWER Fitt's law states that the time it takes to respond is
a function of the amount of information conveyed by the display
Samples of a person's writing using the left hand, right hand, mouth, and then foot are
noticeably similar even though entirely different muscle groups are used in each case.
This is interpreted as support for - ANSWER Generalized motor programs
Say that you increase the resolution of your computer display, such that all you desktop
icons are now smaller. You might find that it takes longer that before to move over to
and click on icons around your screen ( and it seems more effortful). This effect would
then be an example of: - ANSWER Fitts' law
Which statement about anthropometry is false? - ANSWER answer: None of the above
statements are false
Dr. Kathleen Robinette urges engineers use fit mapping, which is using real people on
prototypes and mock-ups to see who fits and who doesn't fit in the product.
There is no average person, because no-one is at the 50th percentile for all their body
dimensions
If you cannot practically or economically design something so that people can adjust it
to fit, then you can design for the average person as a compromise
Body measurements of people in various occupations e.g electrical field worker or truck
driver, can differ in important ways from the body measurements of the human
population as a whole
