The roads of your veins is an interactive biometric-data artwork that allows participants to scan their veins and find the roads that match their vein lines. The vein data as one of the fascinating forms of biometric data contain uniquely complicated lines that resemble the roads and paths surrounding us. The roads resemble how our vein lines are interconnected and how the blood circulates in our bodies in various directions, at various speeds, and in different conditions. This new artwork explores the line segmentation and the structure of veins and compares them to roads in the real world. Through this project, users can explore the correlation between individuals and environments using the hidden patterns under the skin and the vein recognition techniques and image processing. This project also has the potential to lead the way in the interpretation of complicated datasets while providing aesthetically beautiful and mesmerizing visualizations.
