  • Publication number: 20230334486
    Abstract: The present invention solves the conventional problem that it is not possible to use one specific asset such as an avatar in two or more metaverses. An information processing apparatus for realizing one metaverse includes: an instruction receiving unit that receives an asset instruction, which is an instruction to use a specific asset; an asset acquiring unit that acquires compatible asset information corresponding to the one metaverse and the specific asset, from an asset storage unit in which compatible asset information regarding a compatible asset corresponding to one asset is stored in association with each of two or more metaverses; an asset configuring unit that configures a compatible asset that is used in the one metaverse, using the compatible asset information acquired by the asset acquiring unit; and an asset output unit that outputs the compatible asset configured by the asset configuring unit.
