Abstract

A method of operation of a navigation system includes: determining a travel context based on a route condition for providing a navigation guidance; generating a state node having a state content with a control unit based on the travel context; and generating a guidance process based on the state node for presenting a prompt on a device.

Claims

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

determining a travel context based on a route condition for providing a navigation guidance;

generating a state node having a state content with a control unit based on the travel context; and

generating a guidance process based on the state node for presenting a prompt on a device.

2. The method as claimed in claim 1 further comprising generating the state content based on the travel context for adjusting the navigation guidance.

3. The method as claimed in claim 1 further comprising generating a packed option based on the travel context for populating the state content for the state node.

4. The method as claimed in claim 1 further comprising generating a state template based on the travel context for providing a navigation guidance.

5. The method as claimed in claim 1 wherein generating the state node includes generating the state node based on a predefined vicinity for providing the prompt appropriate for the travel context.

6. The method as claimed in claim 1 further comprising generating a packed option for providing the state node suited for the travel context.

7. The method as claimed in claim 1 further comprising validating the guidance process based on a runtime validation for checking whether the guidance process is executable from a beginning instance of the state node to an end instance of the state node.

8. The method as claimed in claim 1 further comprising validating the guidance process based on a runtime verification for checking whether a fallback node is available.

9. The method as claimed in claim 1 further comprising validating the guidance process based on a formal verification for checking whether each instances of the state node is reachable as specified in a state template.

10. The method as claimed in claim 1 further comprising organizing the state content based on an action type for providing the navigation guidance to a destination.

11. A navigation system comprising:

a context module for determining a travel context based on a route condition for providing a navigation guidance;

a node module, coupled to the context module, for generating a state node having a state content with a control unit based on the travel context; and

a topology module, coupled to the node module, for generating a guidance process based on the state node for presenting a prompt on a device.

12. The system as claimed in claim 11 further comprising a content module, coupled to the context module, for generating the state content based on the travel context for adjusting the navigation guidance.

13. The system as claimed in claim 11 further comprising a template module, coupled to the context module, for generating a packed option based on the travel context for populating the state content for the state node.

14. The system as claimed in claim 11 further comprising a template module, coupled to the context module, for generating a state template based on the travel context for providing a navigation guidance.

15. The system as claimed in claim 11 wherein the node module is for generating the state node based on a predefined vicinity for providing the prompt appropriate for the travel context.

16. The system as claimed in claim 11 further comprising a template module, coupled to the context module, for generating a packed option for providing the state node suited for the travel context.

17. The system as claimed in claim 11 further comprising a debug module, coupled to the topology module, for validating the guidance process based on a runtime validation for checking whether the guidance process is executable from a beginning instance of the state node to an end instance of the state node.

18. The system as claimed in claim 11 further comprising a debug module, coupled to the topology module, for validating the guidance process based on a runtime verification for checking whether a fallback node is available.

19. The system as claimed in claim 11 further comprising a debug module, coupled to the topology module, for validating the guidance process based on a formal verification for checking whether each instances of the state node is reachable as specified in a state template.

20. The system as claimed in claim 11 further comprising a content module, coupled to the context module, for organizing the state content based on an action type for providing the navigation guidance to a destination.
