    • In this version, .LOW_CONFIDENCE will be returned as .SUCCESS.

  • We assume many users are still using .SUCCESSin thier validation check, to avoid confusion, we decided to provide .SUCCESS for all usable tracking results.

  • Please make sure both .SUCCESS and .LOW_CONFIDENCE are used for the validation check.

  • In our future release, both .SUCCESS and .LOW_CONFIDENCE will be provided in TrackingState.

  • The onInitailzed() API now provides Error Log.

    • If any validation error happens during the initialization step, Error Log will be displayed.

2.2.1​

January 29, 2021

Common Changes​

  • The eye tracking model has been updated. Compared to the previous version (2.2.0), there is a small improvement in accuracy.

  • The enum InitializationError in onInitailzed() API has been changed. more

  • The startCalibration API contians enum AccuracyCriteria option.

  • .DEFAULT starts normal calibration.

  • .LOW starts easy calibration, easier to pass each step (high possibility to have low accuracy).

  • .HIGH starts strict calibration, harder to pass each step (high possibility to have high accuracy).

  • The GazeInfo in onGaze API contains more types of enum TrackingState.

    • .SUCCESS means current face alignment is in a best position for gaze tracking (returns valid x and y).
    • .LOW_CONFIDENCE means current face alignment is not in the best position, should not be used for precise gaze tracking (returns valid, but less accurate x and y).
    • .UNSUPPORTED means current face alignment is not suitable for gaze tracking (returns invalid x and y).
    • .FACE_MISSING means face is not found.
