Method and device for providing location services

摘要

A method and apparatus for providing a location service are disclosed. The method is performed at a mobile device having one or more processors and memory for storing programs to be executed by the one or more processors. The method includes storing respective geographic positions for a set of points of interest (POIs). The method includes determining a current location and a current viewing direction of a user while storing the respective geographic positions of the set of POIs. The method also includes identifying, based on the stored geographic positions and the current location and viewing direction of the user, a subset of POIs within a current field of view associated with the user from the set of POIs. The method further includes mapping the current location of the user and the respective geographic positions of the subset of POIs onto a user interface displayed on the mobile device.

1. A method of providing navigation assistance, comprising:
at a mobile device having one or more processors and memory for storing programs to be executed by the one or more processors:
storing respective geographic positions for a set of points of interest (POIs);while storing the respective geographic positions of the set of POIs, determining a current location and a current viewing direction of the mobile device;based on the stored geographic positions and the current location and viewing direction of the mobile device, identifying, from the set of POIs, a subset of POIs within a current field of view associated with the mobile device; andmapping the current location of the mobile device and the respective geographic positions of the subset of POIs onto a user interface displayed on the mobile device, further including mapping each POI from the subset of POIs to a respective position on the user interface based at least in part on the current location of the mobile device, the respective geographic position of the POI, and a maximum distance between two POIs from the subset of POIs.
