Abstract: There is provided an apparatus including an imaging unit configured to capture a current image including an information code, the information code being arranged at an arrangement position corresponding to a location within the captured current image, and a control unit configured to determine a difference between a predetermined position and the arrangement position, wherein, when the determined difference is greater than a predetermined threshold, a notification is output to a user, based on the determined difference, to notify of the difference as a guide for adjusting a capturing position of the current image to thereby move the information code to a new arrangement position corresponding to a location of the predetermined position.

Abstract: There is provided a position information processing device including a base station information storage section which stores base station information including position information, a MAC address, and an auxiliary identifier, and position information acquisition section which acquires, based on a MAC address of a base station and an auxiliary identifier acquired by reception of a radio signal transmitted from the base station, position information of the base station from the base station information stored in the base station information storage section.

Abstract: An information processing terminal includes a recognition unit that recognizes an identifier projected over an image, an acquisition unit that acquires data of an object corresponding to the identifier, a processing unit that changes the orientation of the object according to the positional relationship between the information processing terminal itself and the identifier specified based on the image and, when it is no longer able to recognize the identifier, changes the orientation of the object according to the positional relationship between the information processing terminal itself and the identifier specified based on sensor data, and a display control unit that causes the object of which the orientation is changed according to the positional relationship between the information processing terminal itself and the identifier to be displayed over the image in a superimposed manner.

Abstract: An apparatus, method and computer program storage device cooperate to provide a quality position estimation of a mobile communication device by determining a reference area. The reference area includes the position of the mobile communication device as well as a plurality of transmitters. Transmitters that are detected as being outside of the reference area are excluded from contributing to the position estimate. The reference area is centered at a standard position, which may be a previous position or a GPS based position, for example. The range of the reference area includes a component that considers the range of a transmitter, as well as a GPS error or an estimated move distance of the mobile communication device.
