Abstract

A navigation system includes: an image capture unit, configured to capture a gesture; a control unit, coupled to the image capture unit, configured to distinguish between a command motion and a natural motion based on the gesture, an auditory cue, and a contextual information; and generate a command combination for instructing the navigation system based on the command motion and the auditory cue.

Claims

1. A navigation system comprising:

an image capture unit, configured to capture a gesture;

a control unit, coupled to the image capture unit, configured to;

distinguish between a command motion and a natural motion based on the gesture, an auditory cue, and a contextual information; and

generate a command combination for instructing the navigation system based on the command motion and the auditory cue.

2. The system as claimed in claim 1 wherein the control unit is configured to distinguish between the command motion and the natural motion based on a synchronicity of a timing of the gesture and the auditory cue.

3. The system as claimed in claim 1 wherein the control unit is configured to:

identify an auditory signal; and

determine the auditory cue based on the auditory signal, a synonym cluster, and the contextual information.

4. The system as claimed in claim 1 wherein the control unit is configured to generate a motion blacklist for determining the natural motion based on a motion trajectory, the auditory cue, the contextual information, or a combination thereof.

5. The system as claimed in claim 1 wherein the control unit is configured to generate an auditory blacklist for determining the auditory cue based on a speech pattern, the gesture, the contextual information, or a combination thereof.

6. The system as claimed in claim 1 wherein the control unit is configured to:

capture a base image for representing a gesture contour of the gesture;

capture a further image for representing the gesture contour of the gesture; and

determine a motion trajectory based on the base image and the further image.

7. The system as claimed in claim 1 wherein the control unit is configured to:

identify a navigation gesture for generating a navigation route to a destination;

identify a navigation cue; and

generate a navigation command based on the navigation gesture, the navigation cue, the contextual information, or a combination thereof.

8. The system as claimed in claim 1 wherein the control unit is configured to:

identify a page view gesture for arranging a display interface;

identify a page invocation cue;

generate a display command for displaying a graphic page on the display interface based on the page view gesture, the page invocation cue, the contextual information, or a combination thereof.

9. The system as claimed in claim 1 wherein the control unit is configured to:

identify an unlock gesture for unlocking the device;

identify an unlock cue; and

generate an unlocked instance of a device based on the unlock gesture, the unlock cue, the contextual information, or a combination thereof.

10. The system as claimed in claim 1 wherein the control unit is configured to:

identify an affirmative gesture for responding to a question prompt;

identify an affirmative cue; and

generate an affirmative command based on the affirmative gesture, the affirmative cue, the contextual information, or a combination thereof.

11. A method of operation of a navigation system comprising:

capturing, with an image capture unit, a gesture;

distinguishing, with a control unit coupled to the image capture unit, between a command motion and a natural motion based on the gesture, an auditory cue, and a contextual information; and

generating a command combination for instructing the navigation system based on the command motion and the auditory cue.

12. The method as claimed in claim 11 further comprising distinguishing between the command motion and the natural motion based on a synchronicity of a timing of the gesture and the auditory cue.

13. The method as claimed in claim 11 further comprising:

identifying an auditory signal; and

determining the auditory cue based on the auditory signal, a synonym cluster, and the contextual information.

14. The method as claimed in claim 11 further comprising generating a motion blacklist for determining the natural motion based on a motion trajectory, the auditory cue, the contextual information, or a combination thereof.

15. The method as claimed in claim 11 further comprising generating an auditory blacklist for determining the auditory cue based on a speech pattern, the gesture, the contextual information, or a combination thereof.

16. A non-transitory computer readable medium, including instructions for execution, comprising:

capturing a gesture;

distinguishing between a command motion and a natural motion based on the gesture, an auditory cue, and a contextual information; and

generating a command combination for instructing the navigation system based on the command motion and the auditory cue.

17. The non-transitory computer readable medium as claimed in claim 16 further comprising distinguishing between the command motion and the natural motion based on a synchronicity of a timing of the gesture and the auditory cue.

18. The non-transitory computer readable medium as claimed in claim 16 further comprising:

identifying an auditory signal; and

determining the auditory cue based on the auditory signal, a synonym cluster, and the contextual information.

19. The non-transitory computer readable medium as claimed in claim 16 further comprising generating a motion blacklist for determining the natural motion based on a motion trajectory, the auditory cue, the contextual information, or a combination thereof.

20. The non-transitory computer readable medium as claimed in claim 16 further comprising generating an auditory blacklist for determining the auditory cue based on a speech pattern, the gesture, the contextual information, or a combination thereof.
