APPARATUS AND METHOD FOR PLAYING BY INFERRING AND PREDICTING IN UBIQUITOUS SPACE

摘要

An apparatus and a method for reproducing an instance in a ubiquitous space by inferring and predicting the instance are provided to enable a user to have an effect just like moving to a past or future point by reproducing an instance inferred or predicted in a virtual space. A situation sensor(110) senses physical and electric situations in a ubiquitous space, and an information storage(130) stores the sensed physical and electric situations as space-time information. An apace-time reproducer(150) receives a reproducing request for the space-time which is to be reproduced, and reproduces the space-time information, which corresponds to the requested space-time, in a ubiquitous space. If the space-time information is not stored, the space-time reproducer infers the space-time information of past period and predicts the space-time information of future period to reproduce the inferred or predicted space-time information.
