- G01C: MEASURING DISTANCES, LEVELS OR BEARINGS; SURVEYING; NAVIGATION; GYROSCOPIC INSTRUMENTS; PHOTOGRAMMETRY OR VIDEOGRAMMETRY (measuring liquid level G01F; radio navigation, determining distance or velocity by use of propagation effects, e.g. Doppler effects, propagation time, of radio waves, analogous arrangements using other waves G01S)

## Abstract

A method of operation of a navigation system includes: monitoring a participant's movement, the participant's movement is movement to a sequence of locations; identifying a movement area based on the participant's movement in a physical activity; generating a safety zone encompassing the movement area; monitoring an intrusion into the safety zone; and generating a notification of a dangerous situation based on the intrusion for displaying on a device.

## Claims

### Claim 1

A method of operation of a navigation system comprising:
monitoring a participant's movement, the participant's movement is movement to a sequence of locations;
identifying a movement area based on the participant's movement in a physical activity;
generating a safety zone encompassing the movement area;
monitoring an intrusion into the safety zone; and
generating a notification of a dangerous situation based on the intrusion for displaying on a device.

### Claim 2 (depends on 1)

The method as claimed in claim 1 wherein monitoring the intrusion includes:
identifying a spectator's trespass into the safety zone; and
further comprising:
generating a route from a spectator location to outside the safety zone.

### Claim 3 (depends on 1)

The method as claimed in claim 1 further comprising:
identifying the dangerous situation within the safety zone;
pausing the physical activity based on the dangerous situation;
identifying an elimination of the dangerous situation from the safety zone; and
resuming the physical activity based on the elimination.

### Claim 4 (depends on 1)

The method as claimed in claim 1 further comprising:
identifying an obstacle within the safety zone; and
modifying the safety zone to exclude the obstacle.

### Claim 5 (depends on 1)

The method as claimed in claim 1 further comprising identifying a potential collision based on a vision field, a travel speed, and a proximity of a first participant location to an obstacle.

### Claim 6

A method of operation of a navigation system comprising:
monitoring a participant's movement, the participant's movement is movement to a sequence of locations;
generating a practice template from the participant's movement;
identifying a movement area based on the participant's movement in a physical activity;
generating a safety zone encompassing the movement area;
monitoring an intrusion into the safety zone;
generating a notification of a dangerous situation based on the intrusion for displaying on a device; and
displaying the practice template.

### Claim 7 (depends on 6)

The method as claimed in claim 6 further comprising:
identifying a template location from the practice template;
monitoring a performance round for a location deviation from the template location; and
generating a route from a first participant location to the template location.

### Claim 8 (depends on 6)

The method as claimed in claim 6 further comprising:
receiving a margin of error for a location deviation of the practice template;
identifying a distance between a first participant location and a template location exceeding the margin of error; and
generating a second notification of the location deviation.

### Claim 9 (depends on 6)

The method as claimed in claim 6 further comprising:
receiving an event announcement having an event location for the physical activity;
generating a second notification of the event announcement; and
generating a route to the event location.

### Claim 10 (depends on 6)

The method as claimed in claim 6 further comprising:
identifying a conclusion of a performance round of the physical activity; and
generating a second notification of the conclusion of the performance round.

### Claim 11

A navigation system comprising:
a participant module for monitoring a participant's movement, the participant's movement is movement to a sequence of locations;
a record module, coupled to the participant module, for identifying a movement area based on the participant's movement in a physical activity;
a zone module, coupled to the record module, for generating a safety zone encompassing the movement area;
a monitor module, coupled to the zone module, for monitoring an intrusion into the safety zone; and
a notification module, coupled to the monitor module, for generating a notification of a dangerous situation based on the intrusion for displaying on a device.

### Claim 12 (depends on 11)

The system as claimed in claim 11 further comprising:
a navigation module, coupled to the zone module, for generating a route from a spectator location to outside the safety zone; and
wherein:
the monitor module includes an intrusion module, coupled to the navigation module, for identifying a spectator's trespass into the safety zone.

### Claim 13 (depends on 11)

The system as claimed in claim 11 further comprising:
a pause module, coupled to the zone module, for pausing the physical activity based on the dangerous situation;
a status module, coupled to the pause module, for identifying an elimination of the dangerous situation from the safety zone;
a resume module, coupled to the status module, for resuming the physical activity based on the elimination; and
wherein:
the monitor module is for identifying the dangerous situation within the safety zone.

### Claim 14 (depends on 11)

The system as claimed in claim 11 further comprising:
an obstacle module, coupled to the recording module, for identifying an obstacle within the safety zone; and
wherein:
the zone module is for modifying the safety zone to exclude the obstacle.

### Claim 15 (depends on 11)

The system as claimed in claim 11 further comprising a collision module, coupled to the zone module, for identifying a potential collision based on a vision field, a travel speed, and a proximity of a first participant location to an obstacle.

### Claim 16 (depends on 11)

The system as claimed in claim 11 wherein:
the record module is for generating a practice template from based on the participant's movement; and
further comprising:
a display interface, coupled to the record module, for displaying the practice template.

### Claim 17 (depends on 16)

The system as claimed in claim 16 wherein:
the monitor module is for monitoring a performance round for a location deviation from a template location; and
further comprising:
a template module, coupled to the monitor module, for identifying the template location from a practice template; and
a navigation module, coupled to the zone module, for generating a route from a first participant location to the template location.

### Claim 18 (depends on 16)
