comparing a past indicator to the surrounding indicator for recognizing a driving environment; and varying a selectability of a functionality based on the past indicator compared for displaying on a device. ## Claims ### Claim 1 A method of operation of a navigation system comprising: receiving a plurality of a surrounding indicator; filtering the plurality of the surrounding indicator including an environmental factor and a non-environmental factor including an image of an object; filtering a past indicator based on a particular time, a location, and a circumstance for categorizing a driving environment; comparing the past indicator including the image of the environmental factor to the plurality of the surrounding indicator with a control unit for recognizing the driving environment to identify an animate object and an inanimate object, each process to identify the animate object in motion or stationary or the inanimate object in motion or stationary performed independently from one another, and varying a selectability of a functionality based on the past indicator compared for reducing an amount of information displayed on a device. ### Claim 2 (depends on 1) The method as claimed in claim 1 further comprising sending a tracking communication for notifying a target object of a sender location within the driving environment. ### Claim 3 (depends on 1) The method as claimed in claim 1 further comprising receiving a tracking communication for locating a target object within the driving environment. ### Claim 4 (depends on 1) The method as claimed in claim 1 further comprising generating a warning based on the surrounding indicator for recognizing the driving environment. ### Claim 5 (depends on 1) The method as claimed in claim 1 further comprising generating a warning based on the surrounding indicator for reducing a user's speed of a user's vehicle. ### Claim 6 A method of operation of a navigation system comprising: receiving a plurality of a surrounding indicator; filtering the plurality of the surrounding indicator including an environmental factor and a non-environmental factor including an image of an object; filtering a past indicator based on a particular time, a location, and a circumstance for categorizing a driving environment; comparing the past indicator including the image of the environmental factor to the plurality of the surrounding indicator with a control unit for recognizing the driving environment to identify an animate object and an inanimate object, each process to identify the animate object in motion or stationary or the inanimate object in motion or stationary performed independently from one another, for requiring extra attention; and varying a selectability of a functionality based on the past indicator compared for reducing an amount of information displayed on a device. ### Claim 7 (depends on 6) The method as claimed in claim 6 further comprising: changing a display appearance by removing a functionality based on the surrounding indicator; and enabling a voice instruction based on the display appearance with the functionality removed. ### Claim 8 (depends on 6) The method as claimed in claim 6 wherein varying the selectability includes changing a display appearance for removing the selectability of the functionality for reducing distraction. ### Claim 9 (depends on 6) The method as claimed in claim 6 further comprising: filtering the surrounding indicator; and wherein: comparing the past indicator includes factoring the surrounding indicator for improving a reliability for recognizing the driving environment. ### Claim 10 (depends on 6) The method as claimed in claim 6 further comprising defining the environment category for categorizing the driving environment for identifying the driving environment to pay extra attention within the driving environment. ### Claim 11 A navigation system comprising: a capturing sensor for sending a plurality of a surrounding indicator; and a control unit including a processor, coupled to the capturing sensor, for: filtering the plurality of the surrounding indicator including an environmental factor and a non-environmental factor including an image of an object, filtering a past indicator based on a particular time, a location, and a circumstance for categorizing a driving environment, comparing the past indicator including the image of the environmental factor to the plurality of the surrounding indicator for recognizing the driving environment to identify an animate object and an inanimate object, each process to identify the animate object in motion or stationary or the inanimate object in motion or stationary performed independently from one another, and varying a selectability of a functionality based on the past indicator compared for reducing an amount of information displayed on a device. ### Claim 12 (depends on 11) The system as claimed in claim 11 wherein the control unit is for sending a tracking communication for notifying a target object of a sender location within the driving environment. ### Claim 13 (depends on 11) The system as claimed in claim 11 wherein the control unit is for receiving a tracking communication for locating a target object within the driving environment. ### Claim 14 (depends on 11) The system as claimed in claim 11 wherein the control unit is for generating a warning based on the surrounding indicator for recognizing the driving environment. ### Claim 15 (depends on 11) The system as claimed in claim 11 wherein the control unit is for generating a warning based on the surrounding indicator for reducing a user's speed of a user's vehicle. ### Claim 16 (depends on 11) The system as claimed in claim 11 wherein the control unit is for comparing a past indicator to the surrounding indicator for recognizing a driving environment requiring extra attention. ### Claim 17 (depends on 16) The system as claimed in claim 16 wherein the control unit is for: changing a display appearance by removing a functionality based on the surrounding indicator; and enabling a voice instruction based on the display appearance with the functionality removed. ### Claim 18 (depends on 16) The system as claimed in claim 16 wherein the control unit is for changing a display appearance for removing a selectability of the functionality for reducing distraction. ### Claim 19 (depends on 16) The system as claimed in claim 16 wherein the control unit is for: filtering the surrounding indicator; and factoring the surrounding indicator for improving a reliability for recognizing the driving environment. ### Claim 20 (depends on 16) The system as claimed in claim 16 wherein the control unit is for defining the environment category for categorizing the driving environment for identifying the driving environment to pay extra attention within the driving environment.
