MULTIMEDIA APPLICATION METHOD AND SYSTEM USING SENSOR METADATA, USER PREFERENCE METADATA, VIRTUAL OBJECT CAPABILITIES METADATA AND VIRTUAL OBJECT COMMANDS METADATA

摘要

PURPOSE: Sensor information, user preference information, multimedia application method using virtual object command information are provided to control the virtual objects of a virtual world by receiving information from various sensors. CONSTITUTION: A sensor information metadata generator(102) generates sensor information metadata based on sensor information. A virtual object controller(112) controls the virtual object by using virtual object command metadata. A virtual object information metadata generator(106) generates virtual object information metadata according to the generated virtual object information. A virtual object command metadata generator(108) generates the virtual object information metadata according to the virtual object command information.
