Function selection in a portable device coupled to the head unit of a vehicle
A portable device is configured to provide geographic information to a head unit of a vehicle equipped with a display device. One or more processors determine a user context related to a geographic location and detect that the portable device has been communicatively coupled to the head unit of a vehicle. The one or more processors transmit to the head unit, without an express user command, a request that the head unit accept data from the portable device for output via the display device. In response to receiving an indication that that the request has been granted, the one or more processors cause information related to the geographic location to be displayed via the display device, without an express user input at the portable device.
1. A method for providing geographic information to head units of vehicles, the method comprising:
providing, by one or more processors, a set of user interface features of a navigation application executing on a portable device that currently operates in a vehicle, including providing a list of geographic search results from the navigation application to the head unit;
receiving, at the navigation application from a head unit of the vehicle, an indication of a changed environmental condition; and
reducing, by the one or more processors, a level of detail for at least one of the set of user interface features of the navigation application in response to the changed environmental condition, including locking out a scrolling list/paging feature by reducing the list to a single page.
2. The method of claim 1 , wherein receiving the indication of the changed environmental condition includes receiving an indication that the vehicle is moving at a particular speed.
3. The method of claim 1 , wherein receiving the indication of the changed environmental condition includes receiving an indication that windshield wipers in the vehicles are on.
4. The method of claim 1 , wherein providing the set of user interface features includes providing a keyboard, wherein receiving the indication of the environmental condition includes receiving an indication that the vehicle is moving, and wherein reducing the level of detail includes disabling the keyboard while the vehicle is moving.
5. The method of claim 4 , wherein disabling the keyboard while the vehicle is moving is further in response to determining that the vehicle senses no weight in a passenger seat.
6. A portable device comprising:
one or more processors;
an interface configured to couple the portable device to a head unit of a vehicle; and
a non-transitory computer-readable memory storing thereon instructions that, when executed on the one or more processors, cause the portable device to:
provide a set of user interface features, including a keyboard, of a navigation application executing on the portable device,
receive, at the navigation application from the head unit of the vehicle, an indication of a changed environmental condition, including receive an indication that the vehicle is moving, and
reduce a level of detail for at least one of the set of user interface features of the navigation application in response to the changed environmental condition, including disable the keyboard while the vehicle is moving.
7. The portable device of claim 6 , wherein the instructions further cause the portable device to:
provide a list of geographic search results from the navigation application to the head unit, and wherein reducing the level of detail includes reducing the list to a single page.
8. The portable device of claim 7 , wherein the instructions further cause the portable device to lock out a scrolling/list paging feature.
9. The portable device of claim 6 , wherein receiving the indication of the changed environmental condition includes receiving an indication that the vehicle is moving at a particular speed.
10. The portable device of claim 6 , wherein receiving the indication of the changed environmental condition includes receiving an indication that windshield wipers in the vehicles are on.
11. The portable device of claim 6 , wherein disabling the keyboard while the vehicle is moving is further in response to determining that the vehicle senses no weight in a passenger seat.
12. A non-transitory computer-readable medium storing thereon instructions that, when executed by one or more processors, cause the one or more processors to perform a method comprising:
providing a set of user interface features of a navigation application executing on a portable device that currently operates in a vehicle;
receiving, at the navigation application from a head unit of the vehicle, an indication of a changed environmental condition, including receiving an indication that windshield wipers in the vehicles are on; and
reducing a level of detail for at least one of the set of user interface features of the navigation application in response to the changed environmental condition.
13. The non-transitory computer-readable medium of claim 12 , wherein providing the set of user interface features includes providing a list of geographic search results from the navigation application to the head unit, and wherein reducing the level of detail includes reducing the list to a single page.
14. The non-transitory computer-readable medium of claim 13 , the method further comprising locking out a scrolling/list paging feature.
15. The non-transitory computer-readable medium of claim 12 , wherein receiving the indication of the changed environmental condition includes receiving an indication that the vehicle is moving at a particular speed.
16. The non-transitory computer-readable medium of claim 12 , wherein providing the set of user interface features includes providing a keyboard, wherein receiving the indication of the environmental condition includes receiving an indication that the vehicle is moving, and wherein reducing the level of detail includes disabling the keyboard while the vehicle is moving.
