Abstract:
1. A method of determining an object in sight, the object being associated with a Point-Of-Interest (POI) item in a database, the method comprising: estimating a position of an electronic apparatus; estimating a magnitude of error of the estimated position; estimating a direction in which the electronic apparatus is facing using a magnetic sensor of the electronic apparatus; estimating a magnitude of error of the estimated direction; calculating two intersecting imaginary lines in a model of an environment of the electronic apparatus, wherein the two imaginary lines intersect a line of the estimated direction at a side of the electronic apparatus distal to said object, a mutual angle between the two imaginary lines and the line of the estimated direction is based on the estimated magnitude of error of the estimated direction, and the position where the imaginary lines intersect is determined from the estimated position and the magnitude of error of the estimated position, such that an area between the two imaginary lines is formed based on a determined maximum distance of sight; and determining a POI associated with a position within said area such that information about the object associated with the determined POI is obtainable.
