USER PORTABLE TERMINAL FOR RETRIEVING TARGET GEOGRAPHICAL INFORMATION USING A USER'S CURRENT LOCATION AND CURRENT AZIMUTH ANGLE AND PROVIDING SUCH TO USER

摘要

A user portable terminal includes a camera, a GPS receiver for measuring a user's current location, an azimuth angle sensor for measuring an azimuth angle of a user's current line of sight, a memory for storing a plurality of reference areas allocated to target objects on the map and a plurality of tourist information which are correlated with each other, with some of the tourist information, correlated to each of the reference areas, including a plurality of azimuth angle specific tourist information as correlated to a plurality of azimuth angles; and a retrieve module. This retrieve module extracts, from the plurality of reference areas, a reference area containing the user's current location, further extracts, from the plurality of azimuth angle specific tourist information correlated to the extracted reference area, the tourist information corresponding to the user's current azimuth angle as measured, and sends the extracted tourist information to the user.
