CIDI and CONGIC 2015
8 talks about data visualization / information visualization
2 keynote speakers about data visualization:
•  Professor Teal Triggs (Royal College of Art, UK)
•  Ph.D. Fernanda Viegas (Google, USA)

“what is data visualization and for
what purpose it serves?”

“how we can innovate and produce
relevant knowledge through data
visualization?”

“what are the necessary skills and
knowledge areas to produce data
visualizations?”

“how to treat the data
as being linked to
our daily lives? ”

“how to produce
data visualization
with visual appeal?”

But…

Giannella, J. R.; Medeiros, R. | CIDI 2015Source: personal archive

Data is not
necessarily complex,
hermetic and abstract.…

… If the data is dealt with properly
organized and displayed,
it can tell stories.

what are the possible
applications in
data visualization?
and what are the
results of them?

•  Ambient Display Systems
•  Physical interfaces
•  Web interfaces
•  Data journalism
•  Cartographic interfaces

AMBIENT DISPLAY SYSTEMS

•  city buses with GPS;
•  They are traced;
•  Web interface allows you
to check the arrival time
of the buses stop points in the city;
•  require a lot of attention
to get the information.

DATA JOURNALISM

CARTOGRAPHIC INTERFACES
Three innovative features:
1.  multidimensionality – the ability to add n informative layers in
the same map and relate them;
2.  sensors - enables the collection of physical data automatically
through interconnected devices (that characterize the
phenomenon Internet of Things) and the mapping in cartographic
interfaces;
3.  collaboration* - a co-working, multidirectional and decentralized
framework which leads to a a non-hierarchical work relationship.
