Abstract
This short pictorial paper offers a succinct overview and
discussion on an drastically alternative perspective of providing data-driven tools for the visualization of personally relevant data. We describe the notion of information
bombing, the situated, playful and opportunistic approach
to share information in the public realm. We thus present a
wide range of related and self-initiated works in this realm,
in order to demonstrate the rich possibilities of exposing
and externalizing situated data in existing social, cultural
and physical environments, which are the actual source of
such data.

Introduction
Coined by artist Zach Lieberman, the term projection
bombing denotes the use of some sort of mobile or portable light projector to display compelling content within
a public environment. The projection bombing technique
seems to be a relatively effective and exciting way of
reaching a wide, lay audience, mainly by catching urban
passers-by by surprise during their everyday activities.
In recent years, projection bombing has been particularly

exploited by street art and civic
participation kinds of initatives
due to its technical simplicity, financial affordability and
thought-provoking,
guerillastyle - yet still relatively ‘legal’
(at least in comparison to traditional grafitti spraying) - nature
of communication.
Whereas the ‘projected’ content has commonly been focused on showing forms of
artistic expression, recent initatives on civic participation and
information awareness have
been using similar techniques
to introduce abstract information and facts in our everyday
urban environments. These
public, data-centric interventions have not necessarily been
limited to the use of projection
technology. Many alternatives
have been proposed, ranging
from infographics drawn on the
pavement with simple chalk,
to dynamic, light-emitting media architecture installations.
What most of these approaches
have in common is the purpose
to reach a wide audience in an
opportunistic way, by ways of
somewhat unconventional yet
always positive and playful interventions in public space. In

tags on famous monuments to humorously manufactured
conversations painted on residential exterior walls.

addition, the situated use of the
physical environment as an information canvas has been exploited for a rich, experiential
context that tends to augment
the relevance, situatedness and
socio-cultural interpretation of
the content that is shown [8].
We therefore believe that guerrilla-style forms of public dissemination could form a feasible communication medium
for offering engaging, situated
experiences of data that reach
well beyond the typical individualized and screen-focused
experiences of today.

Projection Bombing as
Public Data Visualization
In our previous work, we took
inspiration from street art practice [3] to experiment with
various forms of public information ‘bombing’. For instance,
in Neighborhood Scoreboards
[9], we exposed the energy
usage statistics of multiple
households on chalkboards on
the facades of their homes, in
order to evaluate the impact
of this social exposure on their
energy consumption behavior.
In Street Infographics [2], we
connected casual infovis illus-

trations to existing street signs
in an urban neighbourhood to
inform residents on the actual
socio-demographic
compositions as misconceptions. We
measured their impact, such as
whether these interventions influenced the existing local misconceptions.
We also developed, Architectural Bombing, a mobile projection bombing installation of
our own to experience firsthand its potential capabilities
and issues. The visualizations
showed various socio-demograph facts and relationships
from the actual street the installation was located in. As a
primary design challenge, we
aimed to design the visualizations so that the infographics
physically ‘mapped’ unto the
unique features of the local
house facades. The installation consisted of a rudementary
cart on wheels, with a common
projector, laptop computer and
a GPS-equipped smart phone.
The cart was wheeled along the
street, and the content shown
changed dynamically according to the specific facade that
was passed by. As a result, a
garage door acted as the structural backdrop for a treemap of

household compositions, while
the rectangular bricks of another facade formed a pixel-like
world map to convey the origins
from local inhabitants. In this
study, we were particularly interested in the comprehensibility and usefulness of the communication method.

Public
We have also investigated the
impact of public visualization
when

citizen data, i.e. data submitted
by the citizens themselves, is
projected publicly. Reveal-it!

and community data, originating from participants, based
on self-reported mobile data
entry., Here, we investigated
how onlookers engaged with
the public visualizations of data
originating from themselves,
and how this influenced their
personal reflections and collective discussions [5].
We also studied how interactive
social visualizations influence
the participation and deliberative discourse in public settings
[7]. MyPosition was an interactive visualization of individual
opinions, originating from pass-

ers-by, and based on gesture
interaction. It demonstrated
how the identifiability of individual contributions as well as
playful interaction and representation modalities support or
hamper meaningful participation. We also examined the social interaction patterns caused
by the visualization in its larger
physical context [7].
Novel Tools for Data Collection and Display
We expanded the idea of urban
visualization by not only looking at the impact of the public
visualization of citizen data, but
also by investigating more active strategies for citizen-driven
data collection.
For instance, the Smart Citizen
Sentiment Dashboard (SCSD)
was an interactive and participatory urban visualization
installation that explored the
benefits of combining tangible,
DIY urban interactive devices,
with the opportunistic visual
prominence of media facades
[1]. The interactive technology
was based on simple switch and
knob components, combined
with a (more and more ubiquitous) travel card, based on

their opinion immediately (right). The large-scale urban visualization is can be experienced from different social spots around
the site, such as the side-walk, the cars, the bus-stop or metro entrance (bottom left).

RFID technology. The project made use of DIY components
and smart technology beyond travel purposes and allowed
citizens to express their mood and opinion instantly in the
technology mediated urban realm. As such, the project explored novel ways to motivate and engage citizens with the
discussion of issues and challenges in their city, by letting
them submit and visualize in real-time their opinions.
Discussion
This short pictorial paper offers a succinct overview and discussion on a radically different perspective of data-driven
tools for the visualization of personally relevant data. We
described the notion of information bombing, the situated,
playful and opportunistic appoach to share personal information in the public. In our work, we demonstrate inspiration by a range of artistically motivated, activist or participatory projects and interventions related to civic data and
public space, by their approach of opportunistic augmentation of public spaces with abstract, metaphorical representations of socially- or locally-relevant data, thus seeking to
raise awareness and provoke debate and participation in a
shared and social context.
We present a wide range of related and own works in this
realm, in order to demonstrate the possibilities of exposing and externalizing locally relevant data in existing social
and physical environments, which are the actual source of
such data. With our projects we touch upon a range of digital and non-digital display materials (e.g. projections, LED
facades, street plates, chalkboards), explore the possibilities for architectural adaptation of data visualizations, and
experiment with different ways of data representations, as
well as aqcuisition of self-contributed, personal data (from
mobile and gestural interfaces to playful DIY tangible devices for urban participation).

While our experience in designing and deploying public visualization highlights the potential of opportunistically confronting the public with civic data, we believe that a valuable, and necessary next step would be to provide citizens
with the necessary knowledge and tools to adopt this approach for themselves. Future research could investigate
the range of functionalities, tools and interfaces that facilitate the empowerment of common citizens to create their
own interfaces for information bombing as well as tools for
acquisition, production and adaptation of data-driven visualizations. Some of the following research directions can
thus be explored: adaptable DIY interaces for the bottomup, situated collection of citizen-data; citizen-driven digital
fabrication tools for the production of physical data visualizations (physicalizations) for public use; and mechatronic,
non-digital, and tangible materials for novel display creation and deployment.
