Abstract

To provide effective navigation directions to a user in an automotive environment, a system determines information related to navigating the user to a destination, determines whether a screen of the portable device currently is in a line-of-sight with the user and generates a navigation instruction based on the determined information. Generating the navigation instruction includes selecting a level of detail of visual information for the navigation instruction in view of whether the screen is in the line-of-sight with the user.

Claims

1. A method in a portable device for providing effective navigation directions to a user in an automotive environment, the method comprising:

determining, by one or more processors, information related to navigating the user to a destination;

determining, by the one or more processors, whether a screen of the portable device currently is in a line-of-sight with the user; and

generating, by the one or more processors, a navigation instruction based on the determined information, including selecting a level of detail of visual information for the navigation instruction in view of whether the screen is in the line-of-sight with the user.

2. The method of claim 1, wherein generating the navigation instruction includes selecting the level of detail of visual information further in view of whether the screen is currently turned on.

3. The method of claim 1, wherein generating the navigation instruction includes selecting the level of detail of visual information further in view of whether the user turned off the screen or the screen turned off in response to a timeout event.

4. The method of claim 1, further comprising:

detecting a level of ambient noise;

wherein generating the navigation instruction includes selecting, by the one or more processors, a level of detail of auditory information for the navigation instruction in view of a level of ambient noise.

5. The method of claim 4, including selecting the level of detail of auditory information in view of the selected level of detail of the visual information.

6. The method of claim 1, wherein determining whether the screen is in the line-of-sight with the user includes determining an orientation of the portable device relative to ground.

7. The method of claim 1, wherein determining whether the screen is in the line-of-sight with the user includes determining whether the portable device is located in a cupholder inside a vehicle using at least one of a camera or a proximity sensor.

8. The method of claim 1, wherein determining the information related to navigating the user to the destination includes identifying an upcoming maneuver along a navigation route to the destination, wherein the navigation instructions describes the maneuver.

9. The method of claim 1, wherein determining the information related to navigating the user to the destination includes identifying an alternate route to the destination.

10. A portable device comprising:

one or more sensors configured to generate a signal indicative of a current orientation of the portable device,

a visual interface;

an audio interface; and

a navigation component coupled to the one or more sensors, the visual interface, and the audio interface, the navigation component configured to;

generate a navigation instruction for navigating a user of the portable device to a certain destination,

determine whether the visual interface is likely in view of the user based on the current orientation of the portable device to generate a line-of-sight indication, and

select a first level of detail of visual information and a second level of detail of auditory information for the navigation instruction, to be provided respectively via the visual interface and the audio interface, based on the line-of-sight indication.

11. The portable device of claim 10, further comprising:

a microphone configured to generate a signal indicative of a level of ambient noise,

wherein the navigation component is configured to select the first level of detail and the second level of detail further based on the level of ambient noise.

12. The portable device of claim 10, further comprising:

at least one of (i) a proximity sensor and (ii) a camera,

wherein the navigation component is configured to generate the line-of-sight indication using the at least one of the proximity sensor and the camera.

13. The portable device of claim 10, further comprising:

one or more processors; and

a non-transitory computer-readable medium;

wherein the navigation component includes a plurality of instructions stored on the non-transitory computer-readable medium and executable on the one or more processors.

14. The portable device of claim 13, wherein the non-transitory computer-readable medium stores an indication of whether the user turned off the visual interface, wherein the navigation component is configured to select the first level of detail and the second level of detail further based on whether the user turned off the visual interface.

15. A non-transitory computer-readable medium storing thereon instructions that implement a navigation module which, when executed on one or more processors, is configured to:

generate a navigation instruction for navigating a user of a portable device to a certain destination;

automatically determine whether a visual interface of the portable device is likely in a line-of-sight with the user;

select a level of detail of visual information related to the navigation instruction based at least in part whether the visual interface is likely in the line-of-sight with the user; and

when the selected level of detail is greater than zero, cause the visual information to be provided via the visual interface of the portable device.

16. The non-transitory computer-readable medium of claim 15, wherein the navigation module is further configured to:

determine whether the visual interface is currently active; and

select the level of detail of visual information related to the navigation instruction in view of whether the visual interface is currently active.

17. The non-transitory computer-readable medium of claim 16, wherein the navigation module is further configured to:

in response to determining that the visual interface is currently inactive, determine whether the visual interface was deactivated in response to a command from the user or upon automatically without the command from the user; and

select the level of detail of visual information related to the navigation instruction further in view of whether the visual interface was deactivated in response to the command from the user.

18. The non-transitory computer-readable medium of claim 15, wherein the navigation module is further configured to:

in response to determining that the screen is likely not in the line-of-sight with the user, select a higher level of detail for auditory information related to the navigation instruction, and

cause the auditory information to be provided via an audio interface of the portable device.

19. The non-transitory computer-readable medium of claim 18, wherein the navigation module is further configured to:

determine a level of ambient noise; and

select the level of detail of auditory information related to the navigation instruction further in view of the current level of ambient noise.

20. The non-transitory computer-readable medium of claim 15, wherein to determine whether the screen of the portable device is likely in the line-of-sight with the user, the navigation module is configured to determine an orientation of the portable device in a three-dimensional space.
