Graffiti Codes transform the space around you into a mobile-readable environment. Anyone can draw a simple shape on anything, like graffiti, and the mobile device reads it by simply tracing the outline. It's a human-created VR code. This work diverges from the camera-scanning model and uses accelerometer-based paths to unlock data. Where a QR code cannot be easily generated in the field, Graffiti Codes only require a marker and a surface.
