Abstract
A navigation device has a route re-calculation function. This is activated by the user touching the screen to task away from the normal navigation map mode to a menu screen which displays multiple types of route re-calculation options.
Claims22
A navigation device programmed with a map database and software that enables a route to be planned between two user-defined places, wherein the device is further programmed to be able to display a navigation map on a touch screen display, the navigation map showing a current position of the device on a planned route;
- and wherein the device is further programmed to task away completely from the navigation map, when the touch screen display showing the navigation map screen is touched by a user, to a menu screen which displays a plurality of touch-selectable options relating to route calculation, the touch activation of at least one of which initiates a re-calculation of the route to find a detour away from the planned route.
A method of displaying navigation information, the method being deployed in a navigation device programmed with a map database and software that enables a route to be planned between two user-defined places, wherein the device is further programmed to be able to display a navigation map on a touch screen display, the map showing the current position of the device on a planned route, the method comprising:
- tasking away completely from the navigation map to a menu screen which displays a plurality of user selectable options relating to route calculation by touching the touch screen display showing the navigation map;
- and
- initiating a re-calculation of the route to find a detour away from the planned route by touching at least one of the plurality of user selectable options displayed on the display screen.
Computer software adapted to enable a navigation device, programmed with a map database and software that enables a route to be planned between two user-defined places and displayed on a navigation map on a touch screen display, the map showing the current position of the device on a planned route;
- wherein the software enables a user, by touching the touch screen display showing the navigation map screen, to task away completely from the navigation map to a menu screen which displays a plurality of touch-selectable options relating to route calculation, the touch activation of at least one of which initiates a re-calculation of the route to find a detour away from the planned route.
A method of recalculating a navigation route on an in-vehicle navigation device, the method comprising:
- displaying on a display screen of the navigation device a navigation map showing a current position of the device and a planned route;
- changing the display on the display screen from the navigation map directly to a menu screen which displays a plurality of touch-selectable options relating to route calculation by touching the display screen;
- and
- initiating a calculation of an alternate planned route by touching at least one of the plurality of touch-selectable options on the display screen showing the menu screen.
