Abstract

In one aspect, a device includes at least one processor, a global positioning system (GPS) transceiver accessible to the at least one processor, a motion sensor accessible to the at least one processor, a cellular communication transceiver accessible to the at least one processor, and storage accessible to the at least one processor. The storage bears instructions executable by the at least one processor to provide directions to follow a route to a destination and to vary a rate at which the GPS transceiver communicates with at least one satellite for providing the directions.

Claims

1. A device, comprising:

at least one processor;

a global positioning system (GPS) transceiver accessible to the at least one processor;

a motion sensor accessible to the at least one processor; and

storage accessible to the at least one processor and bearing instructions executable by the at least one processor to;

identify directions to a location;

determine, based on one or more factors related to the directions, at least a first rate at which the GPS transceiver is to communicate with at least one satellite for outputting the directions, the one or more factors comprising at least one speed limit along a route to the location;

output directions for following the route to the location; and

communicate with the at least one satellite at the first rate for at least a portion of the outputting of directions.

2. The device of claim 1, wherein the instructions are executable by the at least one processor to:

in between communications with the at least one satellite at the first rate for at least the portion of the outputting of directions, use dead reckoning to make a determination regarding the directions.

3. The device of claim 2, wherein the determination based on the one or more factors comprises a determination regarding whether the directions are being followed.

4. The device of claim 3, wherein the instructions are executable by the at least one processor to:

receive input from the motion sensor;

use the input from the motion sensor and dead reckoning to make the determination regarding whether the directions are being followed.

5. The device of claim 4, wherein the instructions are executable by the at least one processor to:

responsive to a determination that the directions are not being followed, communicate with the at least one satellite at a second rate that is faster than the first rate.

6. The device of claim 1, wherein the portion is a first portion, and wherein the instructions are executable by the at least one processor to:

determine, based on the one or more factors, at least first and second rates at which the GPS transceiver is to communicate with the at least one satellite for outputting the directions, wherein the first rate is different from the second rate;

output directions for following the route;

communicate with the at least one satellite at the first rate for at least the first portion of the outputting of directions; and

communicate with the at least one satellite at the second rate for at least a second portion of the outputting of the directions, the second portion being different from the first portion.

7. The device of claim 6, wherein the instructions are executable by the at least one processor to:

use the first rate during traversal of a road of a first road type; and

use the second rate during traversal of a road of a second road type.

8. The device of claim 7, wherein the first road type is a highway road type, and wherein the second road type is a city street road type.

9. The device of claim 7, wherein use of the first rate is based on an estimated time until a turn is to be made to follow the route.

10. The device of claim 1 wherein the device comprises a cellular communication transceiver that is accessible to the at least one processor, and wherein the instructions are executable by the at least one processor to:

in between communications with the at least one satellite at the first rate for at least the portion of the outputting of directions, use the cellular communication transceiver to determine whether the directions are being followed.

11. The device of claim 10, wherein the cellular communication transceiver is used to receive location data pertaining to a current location of the device.

12. The device of claim 10, wherein the cellular communication transceiver is used to triangulate a current location of the device.

22. The device of claim 1, wherein the one or more factors comprise at least one of stopping at a point along the route and stopping near a point along the route.

13. (canceled)

14. A method, comprising:

providing, using a device, directions to follow a route to a destination; and

varying, based at least in part on at least one speed limit for at least a portion of the route, a speed at which a global positioning system (GPS) transceiver on the device communicates with at least one satellite for providing the directions.

15. The method of claim 14, wherein the speed varies at least in part based on one or more factors identified by at least one of the device and a server in communication with the device.

16. The method of claim 15, wherein the one or more factors comprise at least one of stopping at a point along the route and stopping near a point along the route.

17. The method of claim 14, wherein the speed varies so that a first speed is used during traversal of a first part of the route and a second speed is used during traversal of a second part of the route, wherein the second speed is faster than the first speed.

18. The method of claim 14, comprising:

using, in between communications of the GPS transceiver with the at least one satellite, input from at least one of a motion sensor and a cellular communication transceiver to track whether the route is being followed.

19. An apparatus, comprising:

a first processor;

a network adapter; and

storage bearing instructions executable by at least one second processor of a first device for;

providing directions to follow a route to a destination; and

varying a rate at which a global positioning system (GPS) transceiver accessible to the second processor communicates with a second device for providing the directions, wherein the at which the GPS transceiver communicates with the second device for providing the directions varies based on at least one speed limit along the route;

wherein the first processor transfers the instructions to the first device over a network via the network adapter.

20. The apparatus of claim 19, wherein the instructions are executable by the processor for:

using, in between communications of the GPS transceiver with the second device, input from at least one of a motion sensor and a cellular communication transceiver; and

varying the rate at which the UPS transceiver communicates with the second device so that a first rate is used during traversal of a first part of the route and a second rate is used during traversal of a second part of the route, wherein the second rate is faster than the first rate.
