GestureRecognizerResult

class GestureRecognizerResult: TaskResult, NSCopying

Represents the gesture recognition results generated by GestureRecognizer.

• init(gestures:handedness:landmarks:worldLandmarks:timestampInMilliseconds:)

  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.

• 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

  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 }

• landmarks

  Hand landmarks of detected hands.

  Declaration

  Swift

  var landmarks: [[NormalizedLandmark]] { get }

• worldLandmarks

  Hand landmarks in world coordinates of detected hands.

  Declaration

  Swift

  var worldLandmarks: [[Landmark]] { get }
