Glance ahead navigation
A navigation system that allows a user to easily glance ahead down a route to see points-of-interest (POI) such as businesses along future portions of a route. POIs within a short distance radius of a selected future exit or other future point along the user's route may be presented to the user via an appropriate display. The short distance radius may be defined by constraints associated with the display (e.g., within a represented distance from the exit that can be shown in a current zoom level of the display). Instead of abandoning a navigation session, use of glance ahead instead suspends navigation while the user views snapshots of points-of-interest at each exit. The navigation system may show branded icons or business details associated with displayed POIs, preferably without the need for the user to access a separate screen.
1 . A method of providing glance ahead points of interest (POI) information along a future segment of a currently calculated route, comprising:
detecting initiation of glance ahead navigation;
receiving user criteria for future POI selection;
selecting a plurality of future POIs meeting said criteria for future POIs, said future POIs being selected during navigation of a calculated route, and said future POIs being proximate a segment of said calculated route significantly beyond a current segment of calculated route;
suspending current navigation;
presenting said plurality of future POIs to a navigation device presenting said calculated route; and
returning to said navigation of said currently calculated route.
2 . The method of providing glance ahead points of interest (POI) information about a future segment of a currently calculated route according to claim 1 , wherein:
said criteria for future POI is a type of POI.
3 . The method of providing glance ahead points of interest (POI) information about a future segment of a currently calculated route according to claim 1 , wherein:
said POIs are selected as being proximate about a given street intersection along said currently calculated route.
4 . The method of providing glance ahead points of interest (POI) information about a future segment of a currently calculated route according to claim 1 , wherein:
said future POIs are proximate to a future freeway exit more than at least 10 miles distant.
5 . The method of providing glance ahead points of interest (POI) information about a future segment of a currently calculated route according to claim 1 , wherein:
said future POIs are proximate to a future freeway exit more than at least 100 miles distant.
6 . The method of providing glance ahead points of interest (POI) information about a future segment of a currently calculated route according to claim 1 , wherein:
said future POIs are selected as being within a given travel time to a closest point along any portion of said currently calculated route.
7 . The method of providing glance ahead points of interest (POI) information about a future segment of a currently calculated route according to claim 1 , further comprising:
providing a user interface permitting a user to customize POI glance ahead searching.
8 . The method of providing glance ahead points of interest (POI) information about a future segment of a currently calculated route according to claim 1 , wherein:
said customized POI glance ahead includes a user-defined distance radius in which glance ahead future POIs are searched and presented to a user interface of a navigation system.
8 . The method of providing glance ahead points of interest (POI) information about a future segment of a currently calculated route according to claim 8 , wherein:
said user-defined distance radius is centered about a selected intersection along said calculated route.
9 . The method of providing glance ahead points of interest (POI) information about a future segment of a currently calculated route according to claim 2 , wherein said type of POI comprises:
businesses.
10 . The method of providing glance ahead points of interest (POI) information about a future segment of a currently calculated route according to claim 1 , wherein:
said future POIs are provided to said navigation system each displayed with a branded icon.
11 . The method of providing glance ahead points of interest (POI) information about a future segment of a currently calculated route according to claim 1 , further comprising:
setting a reminder for later presentation when a vehicle including said navigation system moves into a vicinity of said given future POI.
12 . The method of providing glance ahead points of interest (POI) information about a future segment of a currently calculated route according to claim 1 , wherein:
said glance ahead capability is presented by said user interface as a menu selection.
