Overview

Aboutโ€‹

  • Calibration is a process that improves gaze tracking accuracy by providing information about the user's environment to the SeeSo SDK.
  • Calibration is performed by making the user to focus on one or more points on the screen for a few seconds.

๐Ÿ’ก Does gaze tracking works without calibration?โ€‹

  • Of course it works.
  • However, accuracy is rather low without calibration.

๐Ÿ’ก When should I start calibration?โ€‹

  • In general, it is best to startTracking successfully and do it right after onStarted is called.
  • Re-calibration is also recommended when the gaze tracking accuracy is degraded due to changes in the user's environment or other problems.

Calibration Optionsโ€‹

1. Number of Calibration Points ( CalibrationMode )โ€‹

  • DEFAULT(5 points)
  • ONE_POINT(1 point)
  • FIVE_POINT(5 points)
  • SIX_POINT(6 points)

2. Accuracy Criteriaโ€‹

2-1. DEFAULTโ€‹

  • Start normal calibration process.

2-2. LOWโ€‹

  • Start easy calibration.
  • It requires less time and effort to focus on each calibration point.
  • It has high possibility to have low accuracy.

2-3. HIGHโ€‹

  • Start strict calibration process.
  • It requires more time and effort to focus on each calibration point.
  • It has high possibility to have high accuracy.
