Abstract
Information visualization has been an important tool to reveal hidden patterns in complex data and communicating these findings with many audiences. Data physicalization also offers a promising alternative by representing information through tangible artifacts, enabling more accessible experiences for broader audiences.This dissertation explores the intersection of information visualization and data physicalization in an awareness campaign using space debris as a case study. Despite the risk of collisions, orbital debris remains largely invisible to the public, who rely on satellites for everyday tasks like navigation, telecommunications, and weather monitoring. To address this, we intend to explore how physical artifacts can be used for awareness and engagement. Our preliminary experiments include 3D-printed charts, tactile maps, wearable objects, and data sculptures that transform raw datasets into tangible forms. By examining design considerations, such as material choice, shape, texture, and sensory feedback, we expect to demonstrate how data physicalization can bridge an "invisible" threat and real-world experience. Beyond presenting prototypes, this dissertation also consolidates a reproducible pipeline that links the dataset selection and preprocessing to physical encoding, fabrication strategies, photographic documentation, and the creation of campaign materials. Throughout, constraints such as scale, durability, production time, and cost are treated as design parameters rather than afterthoughts.
