While working at the LIRIS (Informatics Laboratory in Villeurbanne, France) for one year, I was involved in a project M2i about urban mobility, with numerous partners such as Île de France Mobilités, the ADEME (a French public institution for the ecological transition) or Citiway.

During this year, we conducted numerous workshops (see other projects), and manipulated within the team a lot of spatio-temporal data. Working with different dimensions of the data led us to use a lot data physicalization, as a way to manipulate the data quickly as we were speaking together, but also as a way to engage with participants in workshops.

We present a guide that promotes data physicalization's practice in the context of research projects including spatio-temporal data.

The guide

In this guide, you will find a classification of low-tech materials that can be used for data-physicalization of spatio-temporal data.Because the data contain several dimensions, several materials are often required. This is why there is also an assembly table. We also provide examples of data-physicalizations, that we call "recipes" as they can be adapted to other sets of data.

The constraints

- Low-tech and inexpensive materials

- Enabling rapid prototyping "on the fly"

- Guiding the choice of the materials and how they could be better used

Scenarios of use

The preparation of a participatory workshop based on the physicalization of spatio-temporal data. A tool to anticipate material needs and potentially structure the workshop could save time in some cases.


A rapid prototyping situation, producing a tangible draft of a digital data physicalization for example, or a rapid formalization tool for expert discussions around mobility for example.

Research process

Theoretical Background

The materials are chosen according to the materials present in the studied physicalizations, and adapted to more affordable and common materials. The categorization of spatio-temporal data is notably defined by the work of Jacques Bertin, with contributions from Visualization Analysis and Design by Tamara Munzer.

The properties are notably based on the paper by Simon Stusak, Andreas Butz, and Aurélien Tabard, Variables for Data Physicalization Units.

Classification of materials

The different entries allowed the analysis of case studies to be structured and subsequently classified. Most of the case studies come from . Some others are from workshops conducted as part of the M2i project.

As the case studies are for the most part expert and advanced representations, we often had to adapt them to make them easier to implement. In addition, many specific examples of data assemblies are missing. For these reasons, we will set up physicalization workshops in order to produce new study cases, and validate or invalidate the first versions of the tables.

Workshops with participants

During these workshops, I gave the participants a dataset of spatio-temporal data, and asked them to create physicalizations with the materials I had selected for the guide.
