Abstract

Navigation methods and systems are provided. First, an electronic device generates a route planning result according to at least a destination, and performs a navigation process according to the route planning result. It is determined whether at least one navigation condition has occurred. When the navigation condition has occurred, a position schematic diagram is displayed, wherein the position schematic diagram comprises the destination and a current position of the electronic device.

Claims

1. A navigation method for use in an electronic device, comprising:

generating a route planning result according to at least a destination by the electronic device;

performing a navigation process according to the route planning result by the electronic device;

determining whether at least one navigation condition has occurred; and

when the navigation condition has occurred, displaying a position schematic diagram, wherein the position schematic diagram comprises the destination and a current position of the electronic device, wherein the determination of whether the navigation condition has occurred is performed by determining whether the navigation process based on the route planning result has terminated.

2. The method of claim 1, further comprising displaying at least one landmark surrounding the destination.

3. The method of claim 1, wherein the position schematic diagram has a center of the destination.

4. The method of claim 1, wherein the position schematic diagram comprises a circle having a center of the destination and a predefined radius.

5. The method of claim 1, further comprising indicating a distance between the destination and the current position of the electronic device in the position schematic diagram.

6. The method of claim 1, wherein the position schematic diagram is displayed alone, or simultaneously displayed with a map.

7. A navigation system for use in an electronic device, comprising:

a display unit; and

a processing unit generating a route planning result according to at least a destination, wherein the electronic device performs a navigation process according to the route planning result, the processing unit determining whether at least one navigation condition has occurred, and when the navigation condition has occurred, displaying a position schematic diagram in the display unit, wherein the position schematic diagram comprises the destination and a current position of the electronic device, wherein the determination of whether the navigation condition has occurred is performed by determining whether the navigation process based on the route planning result has terminated.

8. The system of claim 7, wherein the processing unit further displays at least one landmark surrounding the destination.

9. The system of claim 7, wherein the position schematic diagram has a center of the destination.

10. The system of claim 7, wherein the position schematic diagram comprises a circle having a center of the destination and a predefined radius.

11. The system of claim 7, wherein the processing unit further indicates a distance between the destination and the current position of the electronic device in the position schematic diagram.

12. The system of claim 7, wherein the position schematic diagram is displayed alone, or simultaneously displayed with a map.

13. A machine-readable storage medium comprising a computer program, which, when executed, causes a device to perform a navigation method, and the method comprising:

generating a route planning result, wherein the device performs a navigation process according to the route planning result;

determining whether at least one navigation condition has occurred; and

when the navigation condition has occurred, displaying a position schematic diagram, wherein the position schematic diagram comprises the destination and a current position of the electronic device, wherein the determination of whether the navigation condition has occurred is performed by determining whether the navigation process based on the route planning result has terminated.
