Gaze position calibrators
=========================
ArGaze provides ready-to-use gaze position calibrator algorithms.
The JSON samples have to be included inside [ArFrame configuration](../advanced_topics/gaze_position_calibration.md) *gaze_position_calibrator* entry to select an algorithm.
```json
"gaze_position_calibrator": {
JSON sample
}
```
Read more about [GazePositionCalibrator base class in code reference](../../../argaze.md/#argaze.GazeFeatures.GazePositionCalibrator).
!!! note
The members indicated as **property** are what returns the matcher.
