Calibration Process

Process.​

1. Start Calibration​

  • Start the calibration by calling the startCalibration function.

2. Calibrating​

2-1. Receive Coordinates of the calibration points​

  • The coordinate of each calibration point is passed through the onCalibrationNextPoint callback function.
  • By using the coordinate, draw calibration point on UI.

2-2. Draw Calibration Point​

  • In order to induce the user to look at the UI by drawing the received coordinates.

2-3. Start Collect Data​

  • Inform the SDK that the UI has been drawn at those coordinates by calling StartCollectSamples. SDK calibrates the coordinates passed from the time of the call.

2-4 Collecting Datas and calculating.​

  • The calibration progress of the coordinates is notified through callback.
  • If there are more coordinates of the required location, repeat steps 2-1 to 2-4.(For example, repeat 5 times for 5-point calibration.)

3. Finish Calibration​

  • The onCalibrationFinished callback is called when all calibration processes are finished.
  • This callback will pass created calibrationData.
  • This calibrationData can be used to save/load user's calibration data.
