We present an intuitive 3D user interface with metaphor of world tree and blocks in VR that allows users to explanatively and enjoyably design a world. HMD users can grasp, move, and rotate the blocks-shaped content floating around the working area in VR by using a finger-tracker or controllers. We developed “VR Safari Park” as an educational application using this explorative interface, User can create a world through connecting blocks to the world tree connector and enjoy interaction with animals.
