Terminology

Data physicalizations, physical visualizations, or data-objects 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.

Physical Visualization

The term "physical visualization" 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]

Data Physicalization

Jansen et al. (2015) suggest to use the term "data physicalization" as a synonym for physical visualization when one does not want to overemphasize the visual sense:

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

The same authors distinguish between data physicalizations as artefacts (for which they suggest the working definition above), data physicalization as the process of giving physical form to data, and data physicalization as a research area that brings together data visualization (infovis and sci-vis) and tangible user interfaces (TUIs):

"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]

Data-Object

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

Data Sculpture

The term "data sculpture" started to be used 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.
