Abstract

This invention relates to a navigation device (200) comprising: a processor (210) that is configured to generate a navigation map of a local environment (497); and a display (240) controllable by said processor (200) to display said navigation map and any markers (489) that relate to marked locations within said local environment (497); characterised in that the navigation device (200) further comprises: an indicator generation module (490) for generating an indicator (491) for each of any marked locations outside of said local environment, said processor (210) being responsive to said indicator generation module (490) to control said display (240) to display any generated indicators (491) in said navigation map (497).

A method of generating a navigation map and a computer program are also disclosed.

Claims

1-25. -25. (canceled)

26. A navigation device comprising:

a processor configured to generate a navigation map of a local environment;

a display controllable by said processor and configured to display said navigation map; and

an indicator generation module for generating an indicator for one or more marked locations outside of a displayed navigation map,

said processor being responsive to said indicator generation module to control said display to display said navigation map and display of any said generated indicators on said navigation map; and

said processor also being responsive to changes in direction by the navigation device, wherein upon a change in direction by the navigation device, the processor changes a position of any said generated indicators displayed on said navigation map.

42. A method of displaying a navigation map on a display of a navigation device, the method comprising:

generating, by at least one processor, a navigation map of a local environment;

determining, by the at least one processor, whether there are any marked locations outside of said local environment;

generating, by the at least one processor, an indicator for display of one or more of said marked locations that are determined to be outside of said local environment;

displaying, on said display of the navigation device, said navigation map and any of said indicators on said navigation map; and

determining, by the at least one processor, a change in direction by the navigation device, and, upon a change in direction by the navigation device, changing a position of any said generated indicators displayed on said navigation map.

44. A non-transitory computer-readable medium having computer software stored thereon, said computer software comprising one or more software modules operable, when executed in an execution environment, to cause a processor to:

generate a navigation map of a local environment;

determine whether there are any marked locations outside of said local environment;

generate an indicator for display of one or more of said marked locations that are determined to be outside of said local environment;

display said navigation map and any of said indicators on said navigation map; and

determine a change in direction by the navigation device, and, upon a change in direction by the navigation device, changing a position of any said generated indicators displayed on said navigation map.
