We transformed a static visual display into a participatory digital canvas. Working alongside LZY, we engineered an interactive drawing experience where visitors could contribute their own designs to the massive projection mapping show. The first experience we helped developed is a digital drawing program to color butterflies. The butterflies will come to life and move around on the walls of the immersive room. The second experience we use LIDAR sensor to detect user movement and position to create portals on the walls and kick digital trash around the room. The system also closed the engagement loop by allowing users to scan and download their artwork instantly.
