APPARATUS AND METHODS OF DISPLAYING NAVIGATION INSTRUCTIONS |
摘要 |
A device is disclosed for generating navigation instructions for display on a display device of a portable navigation device, comprising: means for accessing a repository storing digital map data pertaining to a navigable network along which the navigation device can travel; means for generating, for display on the display device, a three-dimensional perspective view of a model representative of the map data as though from a camera positioned at an elevation and pitch angle behind a current position of the portable navigation device, that is updated to follow the device as it travels along a planned route through the navigable network; and means for generating, in response to detecting that the current position of the navigation device is closer than a predetermined distance to a decision point in the planned route, a fast forward preview of the upcoming decision point by advancing the position of the camera for the three-dimensional perspective view along the planned route at a speed faster than the rate of travel of the current position of the device. Methods of operation of the device, and related computer software, are also disclosed. |

1. A device for generating navigation instructions for display on a display device of a portable navigation device, the device comprising one or more processors arranged to:
access a repository storing digital map data pertaining to a navigable network along which the navigation device can travel; generate, for display on the display device, a three-dimensional perspective view of a model representative of the map data as though from a camera positioned at an elevation and pitch angle behind a current position of the portable navigation device, that is updated to follow the device as it travels along a planned route through the navigable network; and generate, in response to detecting that the current position of the navigation device is closer than a predetermined distance to a decision point in the planned route, a fast forward preview of the upcoming decision point by advancing the position of the camera for the three-dimensional perspective view along the planned route at a speed faster than the rate of travel of the current position of the device. |
