Method and apparatus for trajectory display
First Claim
1. An apparatus for displaying route data received from one or more navigation devices, comprising:
- a display device to display graphical information including one or more trajectories, each trajectory indicating a route travelled by said one or more navigation devices;
a processor arranged to control the display device to display the graphical information;
a store for colour mapping information, said colour mapping information being representative of a relationship between orientation-related information of a trajectory and colour, the orientation information comprising an angle and/or gradient; and
a trajectory-colour module to determine orientation-related information of a trajectory and related colour according to the colour mapping information, said processor being responsive to the trajectory-colour module to control the display device to display a graphical element at least partly in the determined colour, wherein the determined colour provides an indication of a direction of movement or heading of a navigation device on the relevant part of said trajectory.

Abstract
Embodiments of the present invention provide an apparatus including a display device for displaying graphical information; a processor arranged to control the display device to display the graphical information; a store for color mapping information, the information being representative of a relationship between orientation-related information of a trajectory and color; and a trajectory-color module for determining orientation-related information of a trajectory and a color according to the determined information and the color mapping information. In at least one embodiment, the processor is responsive to the trajectory-color module to control the display device to display a graphical element at least partly in the determined color.

11. A graphical display method for displaying, on a display device, route data received from one or more navigation devices, comprising:
-
determining orientation-related information of a trajectory, wherein the trajectory indicates a route travelled by said one or more navigation devices, the orientation-related information comprising an angle and/or gradient; determining a colour corresponding to the orientation-related information; and displaying a graphical element on the display device at least partly in the determined colour, wherein the determined colour provides an indication of a direction of movement or heading of a navigation device on the relevant part of said trajectory. - View Dependent Claims (12, 13, 14, 15, 16, 17)
