  • Patent number: 7527191
    Abstract: A device presents selling information about a virtual region of a selling object in a virtual world. An accepting device accepts a message that represents that a buyer will buy the virtual region of the selling object and information about the buyer. An executing device transfers the right for correlating a processing object with the virtual region of the selling object to the buyer, using at least one of a virtual existence and a virtual region in the virtual world, a virtual existence and a virtual region in another virtual world, and a real existence and a real region in a real world as the processing object. The correlating device correlates identification information of the processing object with identification information of the virtual region of the selling object.

  • Patent number: 7143045
    Abstract: The object of the present invention is to enable an apparatus to perform a status analysis indicated by sensor data of a device, etc. based on an expression in a natural language, and to enable an apparatus to operate a device, etc. by an instruction based on a natural language, using a data process technology for handling data with a word. Data groups, which are obtained by directly classifying the input from sensor 1 or obtained after processing this input, are stored in a database 6, in which a word is attached to each of the data groups. On receiving a sensor input, a characteristic is extracted from the sensor input by a characteristic extractor unit 2, and then the sensor input is classified by a characteristic comparison/classification unit 3 using the database 6. If the sensor input does not belong to any of the data groups in the database 6, the sensor input is temporarily stored in a database 7 with no word.
