Abstract

A navigation device with display based on travel direction and a method thereof are provided. The display mode of navigation images is dynamically regulated according to the change in travel direction of the navigation device. More particularly, the display mode is regulated partially and dynamically according to display positions of navigation points in the navigation images and display ranges of navigation maps, so as to provide a user with more route information and other localization information (Route information and other fixed points information) in the navigation images of the same display regions.

Description

technical field [0001] A navigation device and its navigation method, in particular, a navigation device and its navigation method that can dynamically adjust the display position of relevant navigation points and the display range of a navigation map in a navigation screen according to the real-time traveling direction of the navigation device. Background technique [0002] With the popularization and popularity of navigation devices, more and more people have begun to carry so-called portable navigation devices with them. These navigation devices can be real-time Calculate the current position of the navigation device itself (hereinafter referred to as the navigation point), display the navigation map within a specific range around the navigation point, and provide the establishment and communication of the route (Route) between the navigation point and the waypoint (Waypoint) set by the user. Navigation, as well as providing fixed-point information including food, clothin...
