A device and method for processing virtual worlds. According to embodiments of the present disclosure, information which is measured from the real world using characteristics of a sensor is transferred to a virtual world, to thereby implement an interaction between the real world and the virtual world. The disclosed device and method for processing virtual worlds involve selectively transferring information, from among the measured information, which is different from previously measured information. The disclosed device and method for processing virtual worlds involve transferring the entire measured information in the event that the measured information is significantly different from the previously measured information and for selectively transferring information, from among the measured information, which is different from the measured information in the event that the difference is not significant.
