Abstract

In this paper, we provide an overview of our attempts to harness data physicalizations as pedagogical tools for enhancing the understanding of visual channels. We first elaborate the research goals that we have crafted for the physicalization prototype, shedding light on the key principles that guided our design choices. Then we detail the materials and datasets we employed for nine channels on our physicalization prototype. A preliminary pilot study is followed to validate its effectiveness. In the end, we present our upcoming research initiatives, including a comparative study for assessing the usability of the physicalization system. In general, the main purpose of our work is to stimulate a wider engagement among visualization educators and researchers, encouraging them to delve into the potentialities of data physicalization as an innovative addition to contemporary teaching methodologies.
