Abstract

The invention enables users to virtually attach information to situations in the real world, and also enables users to quickly and easily find out desired information. An IR sensor receives an IR signal transmitted from an IR beacon, and supplies the received signal to a sub-notebook PC. A CCD video camera takes in a visual ID from an object, and supplies the inputted visual ID to the sub-notebook PC. A user inputs, through a microphone, a voice to be attached to situations in the real world. The sub-notebook PC transmits position data, object data and voice data, which have been supplied to it, to a server through a communication unit. The transmitted data is received by the server via a wireless LAN. The server stores the received voice data in a database in correspondence to the position data and the object data.

Claims

1. A wireless communication terminal for communication with two or more wireless base stations, the wireless communication terminal comprising:

acquisition means for acquiring an electric field strength of an electric wave received from each base station and for acquiring a unique ID for each base station;

location estimation means for estimating the relative distance between a present location and a previous location by calculating a correlation between a present combination of said electronic field strength and said unique ID and at least one previous combination of said electronic field strength and said unique ID.

2. A method for location estimation comprising:

receiving an electric field strength of an electric wave from each of a plurality of base stations;

receiving a unique ID from each of said base stations;

estimating the relative distance between a present location and a previous location by calculating a correlation between a present combination of said electronic field strength and said unique ID and at least one previous combination of said electronic field strength and said unique ID.
