Abstract

A method of dynamically adjusting a voice suggested distance for global positioning system (GPS) is provided. The method comprises receiving and decoding a GPS signal first by an electronic device, and then obtaining a speed parameter from the GPS signal. Then, a current driving speed is generated by calculating the obtained speed parameter, and a corresponding suggested distance is sought from a built-in table stored in the electronic device based on the current driving speed. Finally, the suggested distance is updated and registered temporarily. Accordingly, the present invention provides a more human GPS navigation function.

Claims

1. A method of dynamically adjusting a voice suggested distance for global positioning system (GPS) suitable for adjusting a suggested distance to a preset location based on a current driving speed of a mobile device, the method comprising:

receiving and decoding a GPS satellite signal;

obtaining a speed parameter from the decoded GPS satellite signal;

performing a calculation based on the speed parameter;

obtaining the current driving speed;

providing a built-in table with a relationship between a plurality of driving speeds and a plurality of distances stored therein;

according to the relationship between the driving speeds and the distances stored in the built-in table, searching for the corresponding suggested distance among the distances based on the current driving speed;

updating and registering the suggested distance; and

making a sound of a voice suggested and/or a warning beep when the mobile device approaching the suggested distance.
