0PEN:SENSE is an open-source website that grew out of my research into connecting physical sensors with graphic design systems. Before implementing sensors directly into poster prototypes, I conducted a series of experiments in p5.js to translate sensor data into clear visual behavior through geometric shapes and typography. Documenting these tests revealed how fragmented resources around physical computing and graphic visualization can be, which led me to create 0PEN:SENSE as a structured archive. The platform consolidates sketches, interaction recordings, and code samples, making sensor-based visualization tools accessible to other designers and researchers interested in exploring physical-digital interaction.
