Apparatus and Method for Dynamic Navigation of a Selected Geographical Zone

There is provided a handheld device for navigating about a selected geographical zone. The handheld navigating device includes a processor circuit with a screen on which an image representative of a geographical map of a selected geographical zone is displayed. The geographical map of the selected geographical zone includes representations corresponding respectively with points of interest having locations and categories. The geographical map is configured so that (a) at least part of the representations corresponding respectively with points of interest are clustered within at least one viewing area, (b) the at least one viewing area is distinguished by a visible pattern having both a selected appearance and a first visual state that do not reveal the locations and the categories of the points of interest. The handheld navigation device includes a geographical position locating subsystem for determining when a selected relationship exists between the user and one or more of the points of interest. Responsive to the selected relationship existing, the processor circuit changes the appearance of at least part of the visible pattern to both reflect that the at least one viewing area has been transformed from the first visual state to a second visual state and the extent to which the user has traversed the physical area.
