Abstract
A method and devices for a mobile person'"'"'s information retrieval where, when the person is moving, on coming closer to a point of destination, defined by him as being interesting, than a specified threshold separation, he will be informed of such a point of interest and, on request, additional data will be presented on it, such as driving instructions or a map.
The person is also offered a button with which he can make a call to the phone number of the point of interest presented each time. The person can add by himself new points of interest and select from available points of interest individual or several points of interest on the basis of their class, such as, e.g. restaurants or service stations.
