Currently, physicalization research is dominated by technology-centric explorations with limited insights into the broader domain implications. The goal of this workshop is to bring together researchers and practitioners who share an interest in using data physicalizations to solve real-world problems. Hence, we aim to further explore the utility of physicalization for different domains that (already) apply data physicalization in their practices (e.g., sustainability, office vitality, education, and personal informatics). The objective of the workshop is to combine the expertise of researchers working in physicalization and/or exemplar domains to (i) develop an understanding of common challenges, (ii) map out overarching factors across domains, (ii) operationalize design strategies for common domains, and (iv) reflect on the implementation of data physicalizations for different domains. Upon completion of our workshop, we plan to create a BIT Special Issue addressing the challenges and potential directions of the domain application of data physicalizations.
