  • 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).
