Foreword
Visualization research promises to help humans to explore and comprehend infor-
mation, thus making vast stores of data useful to humankind.
Much of this visualization research follows a simple pattern: (1) “here is an
important data set,” (2) “here is a picture of this data set,” (3) “wow, the picture
looks cool!”
Huang’s book does contain some of the world’s coolest pictures of data. But
the book goes further: it considers the much deeper questions of how humans read
visualizations, and why we use visualization. The very nature of visualization is
examined. Visualization is not just a technology; it is a human communication
mechanism.
In particular, the question of what kind of scientific methodology should be used
to evaluate visualizations is considered in detail.
Such topics are beyond the gamut of Computer Science, and can only be
answered by a multidisciplinary approach. The book has chapters written by
researchers in a variety of disciplines, from psychologyto business, from philosophy
to engineering.
The book is revolutionary in its scale and breadth.

Preface
We visualize data for human appreciation and understanding. In other words, all
visualizations are meant to be human centric. However, human centric visualizations
do not come automatically.
To ensure that a visualization is human centric, we need proper theories and
principles to guide the process of the visualization design. Once the visualization is
produced, we need methods and measures to verify whether the design objectives
are indeed achieved. Rapid advances in display technology and computer power
have enabled researchers and practitioners to produce visually appealing pictures.
However, the effectiveness of those pictures in conveying the embedded information
to end users has been relatively less explored.
Handbook of Human Centric Visualization aims to contribute to the human
side of the visualization research. It addresses issues related to design, evaluation,
and application of visualizations. Topics include visualization theories, design
principles, evaluation methods and metrics, human factors, interaction methods,
and case studies. This cutting-edge book is an edited volume whose contributors
include well-established researchers worldwide, from diverse disciplines including
psychology, education, visualization, and human-computer interaction.
This book consists of twenty-nine chapters, which are grouped into the following
seven parts:
I. Visual Communication
II. Theory and Science
III. Principles, Guidelines, and Recommendations
IV. Methods
V. Perception and Cognition
VI. Dynamic Visualization
VII. Interaction

The main features of this book can be summarized as follows:
1. Provides a comprehensive overview of human centric visualization
2. Represents latest developments and current trends in the field
vii
viii Preface
3. Presents visualization theories
4. Covers design principles and guidelines
5. Presents evaluation methodologies and case studies
6. Includes contributions from leading experts and active researchers from a range
of disciplines
This book is designed for a professional audience composed of practitioners,
lecturers, and researchers working in the field of computer graphics, visualization,
human-computer interaction and psychology. Undergraduate and postgraduate stu-
dents in science and engineering focused on this topic will also find this book useful
as a comprehensive textbook or reference.

Acknowledgement
I wish to thank all authors who submitted their valuable work for consideration.
Without their effort and contribution, this book would not have been possible. I
received 84 exciting chapter proposals in total covering almost every aspect of
human centric visualization. Unfortunately,due to limitations on the size of the book
and the range of topics to be addressed, many good proposals were not considered
further.
I thank our valued members of the International Advisory Editorial Board. Their
world class reputation and generous support for this project have helped to attract
the high-quality submissions and receive the overwhelming responses from the wide
scientific community.
Editing a book like this is a time-consuming and sometimes lonely process.
However, throughout this process, I have consistently received positive feedback
and support from many individuals. Some recommended potential authors. Some
helped or offered to help in shaping the book. All this has helped to keep my spirits
high throughout the project. I thank them all. I would also like to extend my special
thanks to Chaomei Chen, Jian Chen, Mary Czerwinski, Andreas Kerren, Stephen
Kosslyn, Fred Paas, Helen Purchase, Barbara Tversky, Jack van Wijk, and Kang
Zhang for their help in one way or another.

I thank Professor Peter Eades for writing the foreword.
My sincere thanks and appreciation are also extended to Springer editors Susan
Lagerstrom-Fife and Courtney Clark for their professional help and support.

Part I
Visual Communication
Visualizing Thought
Barbara Tversky
Abstract Depictive expressions of thought predate written language by thousands
of years. They have evolved in communities through a kind of informal user
testing that has refined them. Analyzing common visual communications reveals
consistencies that illuminate how people think as well as guide design; the process

can be brought into the laboratory and accelerated. Like language, visual commu-
nications abstract and schematize; unlike language, they use properties of the page
(e.g., proximity and place: center, horizontal/up-down, vertical/left-right) and the
marks on it (e.g., dots, lines, arrows, boxes, blobs, likenesses, symbols) to convey
meanings. The visual expressions of these meanings (e.g., individual, category,
order, relation, correspondence, continuum, hierarchy) have analogs in language,
gesture, and especially in the patterns that are created when people design the
world around them, arranging things into piles and rows and hierarchies and arrays,
spatial-abstraction-action interconnections termed spractions. The designed world
is a diagram.
1 Introduction
Communication in the wild is a sound and light show combining words, prosody,
facial expressions, gestures, and actions. Although it is often presumed—think of
the “letter of the law” and transcripts of trials–that meanings are neatly packaged

into words joined by rules into utterances, in fact, other channels of communication
carry significant aspects of meaning, despite or perhaps because of the fact that
they cannot be neatly packaged into units strung together by rules (e.g., [25,
46, 68, 92, 93]). Prosody, as in irony or sarcasm, can overrule and even reverse

meanings of words, as can facial expressions. Pointing can replace words, for things,
for directions, and more, so that natural descriptions, narratives, or explanations
cannot be fully understood from the words alone (e.g., [34]). Gestures go beyond
pointing, they can show size, shape, pattern, manner, position, direction, order,
quantity, both literally and metaphorically. They can express abstract meanings,
mood, affect, evaluation, attitude, and more. Gestures and actions convey this rich
set of meanings by using position, form, and movement in space. Communication
can happen wordlessly, as in avoiding collisions on busy sidewalks or placing items
on the counter next to the cash register to indicate an intention to buy. In fact, the
shelf next to the cash register is designed to play a communicative role. Standing
next to a circle of chatting acquaintances can be a request to join the conversation.
Opening the circle is the group’s wordless response. Rolling one’s eyes can signify,
well, rolling one’s eyes. Communication in the wild combines and integrates these
modes, usually seamlessly, with each contributing to the overall meaning (e.g., [25,
35, 46, 68, 92, 140, 142]).
Gestures and actions are especially convenient because their tools, like the
tools for speech, are free, and they are always with us. But gestures, like speech,
are fleeting; they quickly disappear. They are limited by what can be produced
and comprehended in real time. These limitations render gestures abstract and
schematic. Visualizations, on paper, silk, parchment, wood, stone, or screen, are
more permanent, they can be inspected and reinspected. Because they persist,
they can be subjected to myriad perceptual processes: compare, contrast, assess
similarity, distance, direction, shape, and size, reverse figure and ground, rotate,
group and regroup; that is, they can be mentally assessed and rearranged in multiple
ways that contribute to understanding, inference, and insight. Visualizations can
be viewed as the permanent traces of gestures; both embody and are embodied.
Like gesture, visualizations use position, form, and actions in space to convey
meanings (e.g., [155]). For visualizations, fleeting positions become places and
fleeting actions become marks and forms. Here, we analyze the ways that place
and form constrain and convey meaning, meanings that are based in part in actions.

Traces of visual communication go far back into prehistory. Indeed, they are
one of the earliest signs of culture. They not only precede written language, but
also served as the basis for it (e.g, [42, 114]). Visual communications come in
myriad forms: animals in cave paintings, maps in petroglyphs, tallies on bones,
histories on columns, battles in tapestries, messages on birch bark, journeys in
scrolls, stories in stained glass windows, dramas in comics, diagrams in manuals,
charts in magazines, graphs in journals. All forms of communication entail design,
as the intent of communication is to be understood by others or by one’s self
at another time. Communication design, then, is inherently social, because to be
understood by another or by self at another time entails fashioning communications
to fit the presumed mental states of others or of one’s self at another time.
