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?”


“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 toour daily lives? ”


“how to produce data visualization

with visual appeal?”


But…


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

Data is not necessarily complex,

hermetic and abstract.…


… If the data is dealt with properly organized and displayed,

it can tell stories.

Scientific Visualization

Not physical data such as:•  financial data;•  business data;•  collection of documents;•  abstract concepts.

DATA

Physical spaces of data and /or physical data such as:•  human body;•  planet Earth;•  molecules.

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.

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.
