- Data Physicalization

What if data moved off the screen, with 3D physical shape and materiality? Ongoing research investigates Data Physicalization - physical artefacts whose geometry or material properties encode data. Building on past experience from Trevor Hogan's 'Tactile Data' PhD we have pursued this further, in student projects, as Hannes Waldschütz' and Rosa van Koningsbruggen's research focus and with the DFG Project FluidData on the UX of DataPhys.

DFG Project FluidData - The User Experience of Novel Pneumatic Shape-Changing Interfaces for Dynamic Data Physicalization

March 2020 our new DFG Project FluidData started. This investigates the potential of dynamic shape-changing interfaces for data representation. The project has a constructive-technical and an empirical strand. Project staff: Hannes Waldschütz and Rosa van Koningsbruggen.

On a constructive-engineering level, we will realize controlled shape change via pneumatically actuated (fluidic) membrane structures from  textile/elastomeric material (inflatables) and explore the novel options this offers for shape-change and interaction. For this, we build on and collaborate with Kristian Gohlke's ongoing PhD work. The empirical focus of this project is on the user experience of data physicalization (especially with shape-change). While other research teams have begun investigating performance and accuracy in Data Physicalization, we believe that beyond  pragmatic and utilitarian factors (i.e. usability), there are qualities and benefits related to user affect, sensation and meaning, i.e. UX. For some usage situations, this might be more important for increasing engagement and empathy with data. We will thus investigate terms of qualities and interpretations ascribed to a representation, as well as sense-making processes evoked, including the potential to raise empathy.
