USER INTERFACE CONTROLLED BY ENVIRONMENTAL CUES
A method comprises receiving a signal containing an environmental cue; correlating the environmental cue to a user interface control element; and generating a user interface control command based on the environmental cue. A device may be controlled by receiving a visual image, processing the image to identify a visual cue, correlating the visual cue with a user interface control, and controlling the device using the user interface control. The visual image may be received from a camera that is part of an automobile, and the user interface control may include a control for a radio to tune to a radio station; a speed control for controlling a speed of the automobile corresponding to a speed sign visual cue; or a navigation system control for controlling a navigation system based on traffic signs. Other variations include an apparatus and computer-readable media including instructions for performing the methods.
1 . A method comprising:
activating a cue database for a geographic region;
capturing a visual image of a traffic sign by a camera;
receiving a user input for selecting the visual image for correlation;
in response to the user input for selecting the visual image, correlating, by a processor, the visual image to one or more cues of the activated cue database to control at least one of a radio device, a telephone device, a web browser device, a speed control device, and a navigation device; and
performing a corresponding command, said command comprising at least one of:
a speed control command for the speed control device when the visual image correlates to a speed limit sign,
a detour command for the navigation device when the visual image correlates to a traffic alert,
a dial command for the telephone device when the visual image correlates to a telephone number; and
an update map command for said navigation device when said visual image correlates to a new traffic sign.
2 . The method of claim 1 , further comprising causing the navigation device to enter a detour mode to plan an alternate route in response to selection of the detour command.
3 . The method of claim 1 , wherein the options further comprise a web page loading command for the web browser device when the visual image correlates to a website address.
4 . The method of claim 1 , wherein the options further comprise an update map command for the navigation device when the visual image correlates to traffic routing sign.
5 . The method of claim 1 , wherein correlating comprises receiving user input regarding a user-selected portion of the visual image corresponding to the received signal.
6 . The method of claim 5 , wherein correlating further comprises narrowing the correlation to the user-selected portion of the visual image.
7 . The method of claim 1 , wherein correlating comprises matching a visual cue within the captured image to one of a plurality of potentially matching visual cues stored in a database.
8 . An apparatus comprising:
a display configured to display a user interface;
a user interface for receiving user inputs;
a camera configured to capture a visual image of a traffic sign; and
a processor configured to:
activate a cue database for a geographic region,
receive a user input via the user interface for selecting the visual image for correlation,
in response to the user input for selecting the visual image, correlate the visual image to one or more cues of the activated cue database to control at least one of a radio device, a telephone device, a web browser device, a speed control device, and a navigation device, and
perform a corresponding command, said command comprising at least one of:
a speed control command for the speed control device when the visual image correlates to a speed limit sign,
a detour command for the navigation device when the visual image correlates to a traffic alert,
a dial command for the telephone device when the visual image correlates to a telephone number, and
an update map command for said navigation device when said visual image correlates to a new traffic sign.
9 . The apparatus of claim 8 , wherein the processor is further configured to cause the navigation device to enter a detour mode to plan an alternate route in response to selection of the detour command.
10 . The apparatus of claim 9 , wherein the options further comprise a web page loading command for the web browser device when the visual image correlates to a website address.
11 . The apparatus of claim 9 , the options further comprise an update map command for the navigation device when the visual image correlates to traffic routing sign.
12 . The apparatus of claim 9 , further comprising a database configured to store visual cue patterns, wherein the processor is further configured to match a visual cue within the captured image to one of a plurality of potentially matching visual cues stored in the database.
13 . The apparatus of claim 12 , wherein the visual cues are organized by geographic region.
14 . A non-transitory computer-readable medium storing executable instructions configured to, when executed, cause a processor to:
activate a cue database for a geographic region;
receive a visual image of a traffic sign by a camera;
receive a user input via the user interface for selecting the visual image for correlation;
in response to the user input for selecting the visual image, correlate the visual image to one or more cues of the activated cue database to control at least one of a radio device, a telephone device, a web browser device, a speed control device, and a navigation device; and
perform a corresponding command, said command comprising at least one of:
a speed control command for the speed control device when the visual image correlates to a speed limit sign,
a detour command for the navigation device when the visual image correlates to a traffic alert,
a dial command for the telephone device when the visual image correlates to a telephone number; and
an update map command for said navigation device when said visual image correlates to a new traffic sign.
15 . The computer-readable medium of claim 14 , wherein the executable instructions configured to, when executed, cause a processor to cause the navigation device to enter a detour mode to plan an alternate route in response to selection of the detour command.
16 . The computer-readable medium of claim 15 , wherein the options further comprise a web page loading command for the web browser device when the visual image correlates to a website address.
17 . The computer-readable medium of claim 15 , wherein the options further comprise an update map command for the navigation device when the visual image correlates to traffic routing sign.
18 . The computer-readable medium of claim 15 , wherein the options further comprise an update map command for the navigation device when the visual image correlates to traffic routing sign.
19 . The computer-readable medium of claim 15 , wherein the executable instructions configured to, when executed, cause a processor to match visual cue within a received image to one of a plurality of potentially matching visual cues stored in a database.
