Scan path analyzers
===================
ArGaze provides ready-to-use scan path analysis algorithms.
!!! note "Definition"
A [ScanPath](../../../argaze.md/#argaze.GazeFeatures.ScanPath) is defined as a list of [ScanSteps](../../../argaze.md/#argaze.GazeFeatures.ScanStep) made by a fixation and a consecutive saccade.
The JSON samples have to be included inside [ArFrame configuration](../configuration_and_execution.md) *scan_path_analyzers* entry to select an algorithm.
```json
"scan_path_analyzers": {
JSON sample
}
```
Read more about [ScanPathAnalyzer base class in code reference](../../../argaze.md/#argaze.GazeFeatures.ScanPathAnalyzer).
!!! note
The members indicated as **property** are what returns the analyzer.
## Basic metrics
::: argaze.GazeAnalysis.Basic.ScanPathAnalyzer
### JSON sample
```json
"argaze.GazeAnalysis.Basic.ScanPathAnalyzer": {}
```
## Explore/Exploit ratio
::: argaze.GazeAnalysis.ExploreExploitRatio.ScanPathAnalyzer
### JSON sample
```json
"argaze.GazeAnalysis.ExploreExploitRatio.ScanPathAnalyzer": {
"short_fixation_duration_threshold": 0
}
```
## K coefficient
::: argaze.GazeAnalysis.KCoefficient.ScanPathAnalyzer
### JSON sample
```json
"argaze.GazeAnalysis.KCoefficient.ScanPathAnalyzer": {}
```
## Nearest neighbor index
::: argaze.GazeAnalysis.NearestNeighborIndex.ScanPathAnalyzer
### JSON sample
```json
"argaze.GazeAnalysis.NearestNeighborIndex.ScanPathAnalyzer": {}
```
