Abstract
A method of determining an object in sight with an electronic apparatus, where the object being associated with a Point-Of-Interest, POI, item in a database is disclosed. The method comprises estimating (100) a position of the electronic apparatus by a positioning mechanism; estimating (102) magnitude of error of estimated position; estimating (104) a direction when orienting the electronic apparatus towards the object by a magnetic sensor of the electronic apparatus; estimating (106) magnitude of error of position error of estimated direction; calculating two intersecting imaginary lines in a model of the 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, and where a mutual angle between the two imaginary lines and the line of the estimated direction is based on the estimated magnitude of error of estimated direction, and the position where the imaginary lines intersect is determined from the estimated position and the magnitude of error of estimated position, such that an area between the two imaginary lines is formed (108) based on a determined maximum d…
