Q

describe length/resolution

A

how many levels of the varirable can you detect (ex. line thickness)

22
Q

what is saturation

A

how pure a colour is
amount of grey in the colour
high saturation = little grey

23
Q

what is the best selective visual variable

A

colour

24
Q

characteristics of size

A

selective - yes
associative - yes
quantitative - no
order - yes
length - yes
theoretically infinite but realistically between 5 and 20

25
Q

characteristics of shape

A

selective - meh
associative - meh
quantitative -
order -
length - yes (infinite but realistic ***)

26
Q

characteristice of orientation

A

selective - yes
associative - yes
quantitative -
order -
length - yes (infinite but realistic ***)

27
Q

characteristics of value

A

selective - yes
associative - yes
quantitative -
order - yes
length - yes

28
Q

characteristice of colour

A

selective - yes
associative - yes
quantitative -
order -
length - yes

29
Q

characteristics of texture

A

selective - yes
associative - yes
quantitative -
order -
length - yes

30
Q

patterns and visual representation

A

artistic component
arrangement matters
texture matters

ex. shrubland, orchard, vineyard

31
Q

what is the basis for quantitative maps

A

order

32
Q

graduate symbols > proportional symbols

T/F?

A

True!

33
Q

what are dynamic variables

A

used for visually impaired

for animated and interactive maps

ex. moving mouse around -> when it gets close to something it makes a sound or trigger

34
Q

is dynamic variables and sound variables generally better for nominal or ordinal data

A

ordinal

35
Q

haptic variables

A

used by visually impaired

3 kinds
tactile
kinesthetic
visual analog

36
Q

describe tactile as a haptic variable

A

ex. vibration, flutter, pressure, temperature

used only with ordinal data

37
Q

describe kinesthetic as a haptic variable

A

ex. resistence, friction, location

used only with ordinal data

38
Q

describe visual analog as a haptic variable

A

size, elevation, shape, texture, grain, orientation

can be used for both nominal and ordinal data

39
Q

what is pre attentative processing

A

visual properties noticed before attention
(pre - attention)
detects faster than the brain can think about what it is you are seeing

40
Q

characteristics of pre attentative processing

A

less than 250ms
colour and shape are the primary objects
colour (hue) is probably the best

doesnt matter how many “distractors” there are ti will still work

41
Q

what are the fundamentals of inattentional and change blindness

A

seen but ignored
become blind of other stuff
not related to not paying attention!!!

people are not expecting something to be in that context

hard to see something that you arent expecting

42
Q

what is inattentional blindness

A

failure to notice things right infront of you

43
Q

what is change blindness

A

things that have changed that wasnt being focused on
people dont always see what you may think is obvious

44
Q

why is text and labelling important

A

convey hierarchy
show nominal differences (between categories)
text orientation and embellishments

45
Q

what is sans serif font used for

A

human made (no extra thingy)

46
Q

what is serif font used for

A

natural phenomena
ex. times new romans is the default font for lakes

has the thingy

47
Q

what are font guidelines for sizing

A

minimum pt size of 2pt

for visual hierarchy there needs to be a pt size difference of ATLEAST 2pt

48
Q

what is the importance for interpretation and gestalt

A

see a holistic grouping
make and interpretation
interpret and group (two aspects of gestalt)

49
Q

elements of graphic/image interpretation
(8)

A

shape
size
pattern
tone/hue
texture
shadows
site
association

50
Q

what are the two aspects of gestalt

A

grouping

interpretation

51
Q

essential elements for layouts

A

contrast
visual hierarchy
figure ground
balance
