4. Beat Signer - Department of Computer Science - bsigner@vub.ac.be 4 April 22, 2024 Data Physicalisation ▪ “A data physicalization (or simply physicalization) is a physical artifact whose geometry or material properties encode data.” [Jansen et al., 2015] ▪ “Data physicalisation 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.” [Jansen et al., 2015] ▪ Physical visualisation sometimes used as a synonym for data physicalisations
5. Beat Signer - Department of Computer Science - bsigner@vub.ac.be 5 April 22, 2024 Data Physicalisation … ▪ Data sculptures refer to artistic data physicalisations ▪ “Data sculpture as 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.” [Zhao and Vande Moere] ▪ Multisensory data representation ▪ displaying data in a way that engages multiple senses, such as sight, hearing, touch, etc., to enhance comprehension and interpretation of complex datasets ▪ instead of relying only on visual cues, multisensory approaches incorporate other sensory modalities, allowing us to represent more variables and relationships simultaneously
