Navigation system and method for providing departure times
A navigation system as described herein comprises a processing resource configured to receive destination data representative of a destination, to determine an expected travel time to the destination, and to determine a departure time in dependence upon the expected travel time to the destination, and an output device for providing the departure time to a user.
1. A navigation system comprising:
a processing resource; and
an output device;
wherein the processing resource is configured to:
receive destination data representative of a destination;
determine an expected travel time to the destination;
determine a departure time in dependence upon the expected travel time to the destination, the determining comprising subtracting, from an arrival time for arriving at the destination, a sum of the expected travel time and an offset time, the offset time including at least one of a predetermined arrival time margin and a predetermined departing time margin; and
when the departure time is substantially equal to a current time, provide a corresponding alarm via the output device.
2. The navigation system of claim 1 , wherein the processing resource is further configured to:
receive a specification of the arrival time.
3. The navigation system of claim 1 , wherein the processing resource is further configured to:
receive, from a user, a specification of an amount of time for the at least one of the arrival time margin and the departing time margin.
4. The navigation system of claim 1 , wherein the processing resource is further configured to:
use a default amount of time for the at least one of the arrival time margin and the departing time margin.
5. The navigation system of claim 1 , wherein the processing resource is further configured to:
present, via the output device, a countdown timer that indicates a remaining time until the departure time;
wherein providing the corresponding alarm occurs in addition to and separately from presenting the countdown timer.
6. The navigation system of claim 5 , wherein presenting the countdown timer comprises presenting the countdown timer one of: continuously, periodically, or upon receiving a request.
7. A method of operation of a navigation apparatus that comprises an output device, the method comprising:
receiving destination data representative of a destination at the navigation apparatus;
determining an expected travel time to the destination;
determining a departure time in dependence upon the expected travel time to the destination, the determining comprising subtracting, from an arrival time for arriving at the destination, a sum of the expected travel time and an offset time, the offset time including at least one of a predetermined arrival time margin and a predetermined departing time margin; and
when the departure time is substantially equal to a current time, providing a corresponding alarm via the output device.
8. The method of claim 7 , further comprising:
receiving a specification of the arrival time.
9. The method of claim 7 , further comprising:
receiving, from a user, a specification of an amount of time for the at least one of the arrival time margin and the departing time margin.
10. The method of claim 7 , further comprising:
using a default amount of time for the at least one of the arrival time margin and the departing time margin.
11. The method of claim 7 , further comprising:
presenting, via the output device, a countdown timer that indicates a remaining time until the departure time;
wherein providing the corresponding alarm occurs in addition to and separately from presenting the countdown timer.
12. The method of claim 11 , wherein presenting the countdown timer comprises presenting the countdown timer one of: continuously, periodically, or upon receiving a request.
13. A non-transitory computer readable medium comprising instructions that, when executed by a navigation apparatus that comprises an output device, cause the navigation apparatus to perform a method comprising:
receiving destination data representative of a destination at the navigation apparatus;
determining an expected travel time to the destination;
determining a departure time in dependence upon the expected travel time to the destination, the determining comprising subtracting, from an arrival time for arriving at the destination, a sum of the expected travel time and an offset time, the offset time including at least one of a predetermined arrival time margin and a predetermined departing time margin; and
when the departure time is substantially equal to a current time, providing a corresponding alarm via the output device.
14. The non-transitory computer readable medium of claim 13 , wherein the method further comprises:
receiving a specification of the arrival time.
15. The non-transitory computer readable medium of claim 13 , wherein the method further comprises:
receiving, from a user, a specification of an amount of time for the at least one of the arrival time margin and the departing time margin.
16. The non-transitory computer readable medium of claim 13 , wherein the method further comprises:
using a default amount of time for the at least one of the arrival time margin and the departing time margin.
17. The non-transitory computer readable medium of claim 13 , wherein the method further comprises:
presenting, via the output device, a countdown timer that indicates a remaining time until the departure time;
wherein providing the corresponding alarm occurs in addition to and separately from presenting the countdown timer.
