Providing navigation directions in view of device orientation relative to user
First Claim
Patent Images
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 likely 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 (i) a level of detail of visual information for the navigation instruction, and (ii) a level of detail of auditory information for the navigation instruction, in view of whether the screen is likely in the line-of-sight with the user, whereinselecting the level of detail of visual information includes selecting the level of detail of visual information from among at least three different levels, the three different levels including a first level that includes some but not all visual information available for the navigation instruction and a second level that includes all of the visual information available for the navigation instruction, andselecting the level of detail of auditory information includes (i) selecting a higher level of detail of auditory information when the screen is likely not in the line-of-sight of the user, and (ii) selecting a lower level of detail of auditory information when the screen is likely in the line-of-sight of the user.

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.

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 likely 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 (i) a level of detail of visual information for the navigation instruction, and (ii) a level of detail of auditory information for the navigation instruction, in view of whether the screen is likely in the line-of-sight with the user, wherein selecting the level of detail of visual information includes selecting the level of detail of visual information from among at least three different levels, the three different levels including a first level that includes some but not all visual information available for the navigation instruction and a second level that includes all of the visual information available for the navigation instruction, and selecting the level of detail of auditory information includes (i) selecting a higher level of detail of auditory information when the screen is likely not in the line-of-sight of the user, and (ii) selecting a lower level of detail of auditory information when the screen is likely in the line-of-sight of the user. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

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; determine whether the visual interface is likely in view of a user of the portable device based on the current orientation of the portable device to generate a line-of-sight indication, and generate a navigation instruction for navigating the user to a certain destination, at least in part by selecting a level of detail of visual information and a 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, wherein selecting the level of detail of visual information includes selecting the level of detail of visual information from among at least three different levels, the three different levels including a first level that includes some but not all visual information available for the navigation instruction and a second level that includes all of the visual information available for the navigation instruction, and selecting the level of detail of auditory information includes (i) selecting a higher level of detail of auditory information when the line-of-sight indication indicates the visual interface is likely not in the view of the user, and (ii) selecting a lower level of detail of auditory information when the line-of-sight indication indicates the visual interface is likely in the view of the user. - View Dependent Claims (11, 12, 13, 14)

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:
-
automatically determine whether a visual interface of a portable device is likely in a line-of-sight with a user of the portable device; generate a navigation instruction for navigating the user to a certain destination, at least in part by selecting (i) a level of detail of visual information related to the navigation instruction, and (ii) a level of detail of auditory information related to the navigation instruction, based at least in part on whether the visual interface is likely in the line-of-sight with the user, wherein selecting the level of detail of visual information includes selecting the level of detail of visual information from among at least three different levels, the three different levels including a first level that includes some but not all visual information available for the navigation instruction and a second level that includes all of the visual information available for the navigation instruction, and selecting the level of detail of auditory information includes (i) selecting a higher level of detail of auditory information when the visual interface is likely not in the line-of-sight of the user, and (ii) selecting a lower level of detail of auditory information when the visual interface is likely in the line-of-sight of the user; and when the selected level of detail of visual information is greater than zero, cause the visual information to be provided via the visual interface of the portable device. - View Dependent Claims (16, 17, 18, 19, 20)
