Abstract: An edge-centric space rescaling method which is a new space rescaling technique for registering dissimilar physical-virtual spaces by utilizing the effects of adjusting physical space with redirected walking (RDW) and a system therefor are provided. The edge-centric space rescaling method includes dividing physical space into grid units based on basic geometric information of an object, applying relative translation gains (RTGs) to physical space grids divided in redirected walking (RDW), and registering objects of interest in virtual space to a corresponding target in physical space to rescale the virtual space to the physical space, while maintaining a coordinate system between the virtual space and the physical space.

Abstract: Disclosed are a conversational digital twin method and apparatus using geographic information. A conversational digital twin method using geographic information, which is performed by a computer device, includes obtaining geographic information data converted into 2D or 3D; visualizing the geographic information data in a terminal and providing visualized information to a user; and interacting with the terminal of the user through an artificial intelligence or a voice recognition-based chatbot using a conversational interface to manipulate the visualized information or control an external system.
