Roads in You is an interactive biometric-data art and physical 3D data visualization by using a vein matching process to roads. Veins are beautifully complicated forms hidden under skins. It includes many intersections of roads that resemble the roads and paths surrounding us. In this artwork, participants scan their veins, capture the aesthetically formed vein lines, and observe existing roads in the earth that match to the veins inside of their bodies. The surprising results discovered through this process are visualized in both interactive 3D map visualization and 3D printed sculptures as personal souvenirs as a part of the artistic experience. Unique aspects such as artistic expression and situated metaphors in this artwork invite audiences to experience a unique matching process and discover newly meaningful roads for them. Enhanced 3D data visualization and physical data sculptures are new additions to this updated version. This data-driven artwork aims to find an interesting correlation between biometric data and map-based data in terms of research questions.
