System and method for passive location storage
A system and method for automatically storing a geographic position, without requiring user interaction, makes use of the ability of a location-aware mobile device to detect its state of motion using velocity or type of movement information. A transition between motion states is used to determine a parking location of a vehicle.
1. A method for storing a parking location by a mobile device with access to a memory, the method comprising:
detecting a first motion state, which is a driving state;
detecting a second motion state, which includes all natural human movements;
detecting a third motion state, which is a stopped state where the location remains unchanged for a period of time associated with the transition between the first motion state and the second motion state;
storing, in the memory, a geographic position associated with the stopped state as the parking location.
2. The method of claim 1 , wherein at least one of the steps of detecting includes determining a velocity of the mobile device.
3. The method of claim 2 , wherein at least one of the steps of detecting further includes comparing the determined velocity to a predetermined threshold.
4. The method of claim 1 , wherein at least one of the steps of detecting includes determining a movement type of the mobile device.
5. The method of claim 1 , further comprising, prior to the step of storing, the step of determining if the geographic position is a valid parking location.
6. The method of claim 5 , wherein the valid parking location is determined by geo-fencing.
7. The method of claim 1 , further comprising, prior to the step of storing, the step of requesting an input from a user confirming whether to store the parking location.
8. The method of claim 1 , further comprising the step of retrieving, from the memory, the stored parking location after receiving a request for retrieval from a user.
9. The method of claim 8 , wherein the step of retrieving the stored parking location includes selecting a parking location from a plurality of stored parking locations using a current geographic position of the mobile device.
10. A mobile device comprising:
a motion detector, the motion detector for detecting a first motion state which is a driving state, for detecting a second motion state which includes all natural human movement, and for detecting a third motion state which is a stopped state where the location remains unchanged for a period of time, the third motion state associated with a transition between the first motion state and the second motion state; and
a memory for storing a geographic position associated with the stopped state as a parking location.
11. The mobile device of claim 10 , wherein the motion detector is configured to determine at least one of a velocity of the mobile device and a movement type of the mobile device.
12. The mobile device of claim 11 , wherein the motion detector is configured to compare at least one of the determined velocity and the determined movement type to a predetermined threshold.
13. The mobile device of claim 10 , further comprising, prior to storing the geographic position, the mobile device determining if the geographic position is a valid parking location.
14. The mobile device of claim 10 , further comprising, prior to storing the geographic position, the mobile device requesting an input from a user confirming whether to store the parking location or not.
15. The mobile device of claim 10 , further comprising, the mobile device retrieving, from the memory, the stored parking location after receiving a request for retrieval from a user.
16. The mobile device of claim 15 , wherein the mobile device is configure to select the stored parking location from a plurality of stored parking locations using a current geographic position of the mobile device.
