<p>This paper describes a scheduler system Cue4D matches information for "Time" and "Space," which consists of objects in the environment and surroundings of the person. The system matches the electric device owned by the user and the space with the RFID tags by scheduled time and user's behavior, then, the system reports the scheduled information to the user. We show the feasibility and effectiveness of the proposed system by implementation of the prototype system and experimental results.</p>
