  2. 2. My timeline of studies in Information Design and Visualization 2005-2011 Rodrigo Medeiros Assistant Professor, IFPB, Design PhD Candidate, UFPE, Computer Science October 7, 2014 Boston Northeastern University
  3. 3. Background • Undergraduate: Web Design or system for web • MBA: Information Design • Master: Technology and Digital Art, Universidade do Minho • PhD candidate: Computer Science, Universidade Federal de Pernambuco Warning -­‐ Real Time Global Air Quality Display 4
  4. 4.

  7. 7. Warning – real time global air quality display Warning - Real Time Global Air Quality Display is an installation of ambient display that receives data from the internet about the air quality in 30 cities in 5 continents. The installation of these data is dynamically displayed on a screen and a physical structure through a lighting system (LED) located in a public space. Warning -­‐ Real Time Global Air Quality Display 8
  8. 8. Motivation • Digital aesthetics of climate change (Pold, 2010) – Artworks in digital art involving the issue of the environment as a theme. • Eco-visualization (Holmes, 2007) – can be defined as animations controlled by data that show any kind of environmental information in real-time. Warning -­‐ Real Time Global Air Quality Display 9

  12. 12. state of the art – information visualization • The information visualization aims to expand knowledge through the development of effective visual metaphors for mapping abstract data (Card; Mackinlay; Shneiderman, 1999). raw data > visual mapping > visualization Warning -­‐ Real Time Global Air Quality Display 13
  13. 13. state of the art – information visualization • “Information Visualization is abstract data communication through the use of interactive visual interfaces” (Keim et al, 2006) • “uses computer graphics and interaction to help humans in solving problems” (Purchase et al, 2008).

  22. 22. Warning – Steps - Construction and structure of installation Warning -­‐ Real Time Global Air Quality Display 23
  23. 23. 24 Warning – Steps - Definition and validation of display parameters • Chromatic scale proposed by me • Validation (two sessions of card sorting) • Comparison with existing scales (final scale): Best air quality Worst air quality Warning -­‐ Real Time Global Air Quality Display
  24. 24. 25 Warning – Steps – Hardware Development • Analysis of proposals: • Implemented solution

  33. 33. 41 Warning – Steps – Critical analysis 4 people for one week: • More time for dynamic visualization; • Debate about air quality; • Recalled the most general images of clouds; • Leaves the space more welcoming; • More works of this kind in public space; Warning -­‐ Real Time Global Air Quality Display
  34. 34. Possibilities • The art and technology in encouraging debate on environmental issues. • Lack of global standardization of air quality index. • Looking beyond the traditional use of the screen as an interface. Warning -­‐ Real Time Global Air Quality Display 42
  35. 35. Positive Hypothesis • Interface non-screen-based + softwares and hardwares open-source -> new aesthetic experiences built and coded with low cost. Warning -­‐ Real Time Global Air Quality Display 43
  36. 36. Future work • Wireless LEDs • Research on another alternative display • Projects with environmental subject • More public and standardized databases among governments / international institutions Warning -­‐ Real Time Global Air Quality Display 44
