Physical variables to shape individual interpretations into collective knowledge

This contribution presents a participatory approach to data physicalization that explores physical variables as generative devices for meaning-making. It is presented as part of the workshop Craft-Based Data Physicalization: Opportunities and Challenges at the CHI 2026 Conference in Barcelona, organised by Bakhtiari et al. The workshop investigates how craft techniques and material properties can expand the design space of data physicalization and support new ways of engaging with data through hands-on making. The workshop call is available at https://onlineacademiccommunity.uvic.ca/craftphysicalization/. The contribution draws on my PhD research and presents a case study in which participants used Data-Probes, geometric components designed to foreground material properties, to articulate embodied experiences of urinary tract infection symptoms. The results highlight how gestures, material affordances, and experimental assembly support the interpretation and communication of intimate and personal data.
