Warning - Real Time Global Air Quality Display: case study of digital art and
public spaces
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.

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.

• Art of the City -> outside the museums -> everyday life
• Late 1960s: crisis of traditional exhibition spaces (museums and galleries)

• The information visualization aims to expand knowledge through the development of effective visual metaphors for mapping abstract data (Card; Mackinlay; Shneiderman, 1999).

• “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).

Van Moere and Offenhuber (2009) propose a classification for alternative display of information.
• Ambient display
• Object augmentation
• Data sculpture / Pixel sculpture

• Air quality • Air quality index:
• Carbon monoxide (CO) • Nitrogen dioxide / nitrogen (NO2) • Sulfur dioxide (SO2) • Ozone (03) • Fine particles and inhalable particles.

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 – Steps –
Critical analysis
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.
42 Warning -‐ Real Time Global Air Quality Display
Positive Hypothesis
• Interface non-screen-based + softwares and hardwares open-source -> new aesthetic experiences built and coded with low cost.
43 Warning -‐ Real Time Global Air Quality Display
Future work
• Wireless LEDs
• Research on another alternative display
• Projects with environmental subject
• More public and standardized databases among governments / international institutions
