MPPGestureRecognizerResult


@interface MPPGestureRecognizerResult : MPPTaskResult

Represents the gesture recognition results generated by GestureRecognizer.

  • Hand landmarks of detected hands.

    Declaration

    Objective-C

    @property (nonatomic, readonly) NSArray<NSArray<MPPNormalizedLandmark *> *> *_Nonnull landmarks;

  • Hand landmarks in world coordinates of detected hands.

    Declaration

    Objective-C

    @property (nonatomic, readonly) NSArray<NSArray<MPPLandmark *> *> *_Nonnull worldLandmarks;

  • Handedness of detected hands.

    Declaration

    Objective-C

    @property (nonatomic, readonly) NSArray<NSArray<MPPCategory *> *> *_Nonnull handedness;

  • Recognized hand gestures of detected hands. Note that the index of the gesture is always -1, because the raw indices from multiple gesture classifiers cannot consolidate to a meaningful index.

    Declaration

    Objective-C

    @property (nonatomic, readonly) NSArray<NSArray<MPPCategory *> *> *_Nonnull gestures;

  • Initializes a new GestureRecognizerResult with the given landmarks, world landmarks, handedness, gestures and timestamp (in milliseconds).

    Declaration

    Objective-C
