Data physicalizations or physical visualizations are data-driven physical artefacts. They are the physical counterparts of data visualizations. Such artefacts may involve the use of computers, either to fabricate them or to actuate them. A closely related term is data sculpture.

Terminologie

Visualisation physique

Le terme "visualisation physique" ("physical visualization" ) est apparu dans la littérature de visualisation de l'information vers 2008. The term appeared in the information visualization literature around 2008 [1][2]. According to Jansen et al. (2013):

"Traditional visualizations map data to pixels or ink, whereas physical visualizations map data to physical form." [3]

Physicalisation de données

Jansen et al. (2015) introduisent le terme "data physicalization" comme synonyme de visualisation physique quand on ne veut pas trop insister sur le sens visuel:

"A data physicalization (or simply physicalization) is a physical artifact whose geometry or material properties encode data." [4]

Les mêmes auteurs font la distinction entre (a) la matérialisation des données en tant qu’artefacts (pour laquelle ils suggèrent la définition ci-dessus), (b) la physicalisation des données en tant que processus qui donne une forme matérielle aux données, et la physicalisation de données en tant que domaine de recherche qui marie visualisation de données (infovis) avec les interfaces utilisateurs tangibles:

"We propose to think of Data Physicalization as a research area that examines how computer-supported, physical representations of data (i.e., physicalizations), can support cognition, communication, learning, problem solving, and decision making." [4]

Objet de données

Gwilt et al. (2012) coined the term "data-object" to refer to "physical artefacts based on data extracted from statistical digital information systems." [5]

Sculpture de données

The term "data sculpture" probably first appeared around 2005 [6], gained traction in 2008 and became popular around 2014 [7]. Data sculptures generally refer to artistic data physicalizations. According to Zhao and Vande Moere (2008), a data sculpture is:

"a data-based physical artifact, possessing both artistic and functional qualities, that aims to augment a nearby audience’s understanding of data insights and any socially relevant issues that underlie it." [2]

For artist Loren Madsen (2015), a data sculpture is:

"three-dimensional data art", i.e., "art whose form in large part is determined by data or information." [8]

As for Jansen et al. (2015), they refer to data sculptures as:

"data-driven artifacts [...] built by artists and designers who seek to elicit emotions and convey meaning beyond mere data" [4]

Kinetic Sculpture

Data sculptures, like regular sculptures, are typically static. Kinetic sculptures are dynamic, but do not necessarily show data. However, there exist several examples of kinetic data sculptures.
