This paper presents a system that generates a magical experience with full-body motion. The system consists of a locomotion interface and a spatial immersive display. A virtual experience system named the Magical Experience Generator was developed, equipped with a Magical Experience Controller. This system provides a physical movement experience along with magical-like interactions in a virtual space. We developed content inspired by the Japanese story "The Man Who Made Flowers Bloom" using Unity as the system's environment. The locomotion interface records the participant's walking trajectory and hand movements, representing their actions in the virtual space.
