GestureRecognizerResult

class GestureRecognizerResult: TaskResult, NSCopying

Represents the gesture recognition results generated by GestureRecognizer.

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

    Declaration

    Swift

    init(gestures: [[ResultCategory]], handedness: [[ResultCategory]], landmarks: [[NormalizedLandmark]], worldLandmarks: [[Landmark]], timestampInMilliseconds: Int)

    Parameters

    landmarks

    The hand landmarks of detected hands.

    worldLandmarks

    The hand landmarks in world coordinates of detected hands.

    handedness

    The handedness of detected hands.

    handedness

    The recognized hand gestures of detected hands.

    timestampInMilliseconds

    The timestamp for this result.

    Return Value

    An instance of GestureRecognizerResult initialized with the given landmarks, world landmarks, handedness and gestures.

  • 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

    Swift

    var gestures: [[ResultCategory]] { get }

  • Handedness of detected hands. Note: Left and Right handedness correspond to the subject's hands, not the viewer. Passing a horizontally mirrored image will invert these outputs.

    Declaration

    Swift

    var handedness: [[ResultCategory]] { get }

  • Hand landmarks of detected hands.

    Declaration

    Swift

    var landmarks: [[NormalizedLandmark]] { get }

  • Hand landmarks in world coordinates of detected hands.

    Declaration

    Swift

    var worldLandmarks: [[Landmark]] { get }
