This is an immersive media facade and interactive floor projection planning project that redefines the nocturnal landscape of the Seomjin River Otter Ecology Park in Gurye, Jeollanam-do. By presenting the adventures of the park's symbolic 'otter' and the wondrous seasonal changes of the Seomjin River through high-quality 3D animation and media art, we have transformed a plain building exterior into a vibrant canvas of light. Notably, we integrated 'real-time interactive sensor technology' onto the plaza floor, which generates water ripples in response to visitors' steps and renders scattering cherry blossoms and footprints on snowy ground. Designed to go beyond simple visual observation and make visitor actions an integral part of the content, this high-end immersive content maximizes the spatial value and dwell time of the nighttime theme park.
