Overview

About​

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

💡 Does gaze tracking works without calibration?​

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

💡 When should I start calibration?​

  • 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 Options​

1. Number of Calibration Points ( CalibrationMode )​

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

2. Accuracy Criteria​

2-1. DEFAULT​

  • Start normal calibration process.

2-2. LOW​

  • 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. HIGH​

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