INSUFFICIENT DATA FOR MEANINGFUL ANSWER.
The Eyes Have It
A Research Paper by Ben ShneidermanThe trend is your friend 'til the bend at the end
A Fragment by Noah SmithIn the past, GDP and resources use have always been tightly correlated. But this is just drawing a line through some data — it’s not based on any deep theory. And in fact, these correlations can change very quickly. Just as one example, here’s energy use versus GDP since 1949.
If you were sitting in 1970, you could look at this curve and claim, very confidently, that economic growth requires concomitant increases in energy use. And you’d be wrong. Because the trend is your friend til the bend at the end.
Embracing Asymmetrical Design
An Article by Ben NadelHumans love symmetry. We find symmetry to be very attractive. Our brains may even be hard-wired through evolution to process symmetrical data more efficiently. So, it's no surprise that, as designers, we try to build symmetry into our product interfaces and layouts. It makes them feel very pleasant to look at.
Unfortunately, data is not symmetrical…Once you release a product into "the real world", and users start to enter "real world data" into it, you immediately see that asymmetrical data, shoe-horned into a symmetrical design, can start to look terrible.
To fix this, we need to lean into an asymmetric reality. We need to embrace the fact that data is asymmetric and we need to design user interfaces that can expand and contract to work with the asymmetry, not against it. To borrow from Bruce Lee, we need to build user interfaces that act more like water:
“You must be shapeless, formless, like water. When you pour water in a cup, it becomes the cup. When you pour water in a bottle, it becomes the bottle. When you pour water in a teapot, it becomes the teapot. Water can drip and it can crash. Become like water my friend.” — Bruce Lee
Goodbye, Google
An Article by Douglas BowmanWithout a person at (or near) the helm who thoroughly understands the principles and elements of Design, a company eventually runs out of reasons for design decisions. With every new design decision, critics cry foul. Without conviction, doubt creeps in. Instincts fail. “Is this the right move?” When a company is filled with engineers, it turns to engineering to solve problems. Reduce each decision to a simple logic problem. Remove all subjectivity and just look at the data. Data in your favor? Ok, launch it. Data shows negative effects? Back to the drawing board. And that data eventually becomes a crutch for every decision, paralyzing the company and preventing it from making any daring design decisions.
Yes, it’s true that a team at Google couldn’t decide between two blues, so they’re testing 41 shades between each blue to see which one performs better. I had a recent debate over whether a border should be 3, 4 or 5 pixels wide, and was asked to prove my case. I can’t operate in an environment like that. I’ve grown tired of debating such minuscule design decisions. There are more exciting design problems in this world to tackle.
The Subtleties of Color
A Series by Robert SimmonThe use of color to display data is a solved problem, right? Just pick a palette from a drop-down menu (probably either a grayscale ramp or a rainbow), set start and end points, press “apply,” and you’re done. Although we all know it’s not that simple, that’s often how colors are chosen in the real world. As a result, many visualizations fail to represent the underlying data as well as they could.
Data Farming
A Research PaperMiners seek valuable nuggets of ore buried in the earth, but have no control over what is out there or how hard it is to extract the nuggets from their surroundings. ... Similarly, data miners seek to uncover valuable nuggets of information buried within massive amounts of data.
Farmers cultivate the land to maximize their yield. They manipulate the environment to their advantage using irrigation, pest control, crop rotation, fertilizer, and more. Small-scale designed experiments let them determine whether these treatments are effective. Similarly, data farmers manipulate simulation models to their advantage, using large-scale designed experimentation to grow data from their models in a manner that easily lets them extract useful information.
Interaction of Color
The deception of color
In order to use color effectively it is necessary to recognize
that color deceives continually.What counts here – first and last – is not so-called knowledge
of so-called facts, but vision – seeing.Practice before theory
Instead of mechanically applying or merely implying laws and rules
of color harmony, distinct color effects are produced
– through recognition of the interaction of color –
by making, for instance,
2 very different colors look alike, or nearly alike.The aim of such study is to develop – through experience
– by trial and error – an eye for color.
This means, specifically, seeing color action
as well as feeling color relatedness.As a general training it means development of observation and articulation.
This book, therefore, does not follow an academic conception
of “theory and practice.”
It reverses this order and places practice before theory,
which, after all, is the conclusion of practice.50 reds
If one says “Red” (the name of a color)
and there are 50 people listening,
it can be expected that there will be 50 reds in their minds.
And one can be sure that all these reds will be very different.Not the what but the how
Our concern is the interaction of color; that is, seeing
what happens between colors.We are able to hear a single tone.
But we almost never (that is, without special devices) see a single color
unconnected and unrelated to other colors.
Colors present themselves in continuous flux, constantly related to
changing neighbors and changing conditions.As a consequence, this proves for the reading of color
what Kandinsky often demanded for the reading of art:
what counts is not the what but the how.Scotopic seeing
The sensitivity
and consequently the registration of the retina of an eye is different
from the sensitivity and registration of a photographic film.Normally, black-and-white photography registers all lights lighter
and all darks darker than the more adjustable eye perceives them.
The eye also distinguishes better the so-called middle grays,
which in photography are often flattened if not lost.This shows what a higher key in light can lose in photography.
The greatest advantage the eye has over photography
is its scotopic seeing in addition to its photopic seeing.
The former means, briefly, the retinal adjustment to lower light conditions.Disliked colors
We try to recognize our preferences and our aversions –
what colors dominate in our work; what colors, on the other hand,
are rejected, disliked, or of no appeal. Usually a special effort
in using disliked colors ends with our falling in love with them.Color intervals
The tune of “Good morning to you” consists of 4 tones. It can be sung
in a high soprano, a low basso, and in all in-between voices, as well as
on many levels and in many keys. It can be played on innumerable instruments.In all possible ways of performance, this melody will keep its character
and it will be recognized instantly.Why? The intervals of the 4 tones, that is, their acoustical
constellation (again comparable with a topographical relationship),
remains the same.Although it is not common practice, one can also speak of intervals
between colors.
Colors and hues are defined, as are tones in music, by wavelength.Any color (shade or tint) always has 2 decisive characteristics:
color intensity (brightness) and light intensity (lightness).
Therefore, color intervals also have this double-sidedness, this duality.Time and space
Tones appear placed and directed predominantly in time from before to now to later.
Their juxtaposition in a musical composition is perceived
within a prescribed sequence only.
Horizontally, the tones follow each other,
perhaps not in a straight line, but of necessity in a prescribed order
and only in 1 direction – forward.
Tones heard earlier fade, and those farther back disappear, vanish.
We do not hear them backward.Colors appear connected predominantly in space. Therefore,
as constellations they can be seen in any direction and
at any speed. And as they remain, we can return to them repeatedly
and in many ways.
This remaining and not remaining, or vanishing and not vanishing,
shows only 1 essential difference between the fields of tone
and color.The accuracy of perception in one field is matched
by the durability of retention in the other, demonstrating
a curious reversal in visual and auditory memory.A cook with taste
Observe the interior and exterior, the furniture and textile decoration
following such color schemes, as well as commercialized color “suggestions”
for innumerable do-it-yourselves.Our conclusion: we may forget for a while those rules of thumb
of complementaries, whether complete or “split”, and of triads and
tetrads as well.
They are worn out.Second, no mechanical color system is flexible enough
to precalculate the manifold changing factors, as named before,
in a single prescribed recipe.Good painting, good coloring, is comparable to good cooking.
Even a good cooking recipe demands tasting and repeated tasting
while it is being followed.
And the best tasting still depends on a cook with taste.Flexible imagination
By giving up preference for harmony,
we accept dissonance to be as desirable as consonance.Besides a balance through color harmony, which is comparable
to symmetry, there is equilibrium possible between
color tensions, related to a more dynamic asymmetry.Again: knowledge and its application is not our aim;
instead, it is flexible imagination, discovery, invention – taste.Does it have color?
Whether something “has color” or not is as hard to define verbally as are
such questions as “what is music” or “what is musical."The Weber-Fechner law
Exponential increases in physical stimuli produce linear perceptual increases.
Thinking in situations
Naturally, practice is not preceded but followed by theory.
Such study promotes a more lasting teaching and learning
through experience. Its aim is development of creativeness
realized in discovery and invention – the criteria of creativity,
or flexibility, being imagination and fantasy. Altogether
it promotes “thinking in situations,” a new educational concept
unfortunately little known and less cultivated, so far.Not of method but of heart
In the end, teaching is a matter not of method but of heart.
The teacher actually is right and always will gain confidence
when he admits that he does not know, that he cannot decide, and,
as it often is with color, that he is unable to make a choice
or to give advice.Besides, good teaching is more a giving of right questions
than a giving of right answers.Results of a search
This book presents results of a search, not of what is academically called research.
In addition to the dedication of this book, I should like to state that my students in color have taught me more color than have books about color.
Simple forms
The concept that “the simpler the form of a letter the simpler its reading” was an obsession of beginning constructivism. It became something like a dogma, and is still followed by “modernistic” typographers.
This notion has proved to be wrong, because in reading we do not read letters but words, words as a whole, as a “word picture.” Ophthalmology has disclosed that the more the letters are differentiated from each other, the easier is the reading.
Without going into comparisons and the details, it should be realized that words consisting of only capital letters present the most difficult reading—because of their equal height, equal volume, and, with most, their equal width. When comparing serif letters with sans-serif, the latter provide an uneasy reading. The fashionable preference for sans-serif in text shows neither historical nor practical competence.
