Gives information about a hand detected within a frame from a Leap Motion device.
ID
- A unique ID for this hand.Transform
- Transforms a forward-facing object so it is at the center of the palm, facing toward the fingers, scaled to the width of the palm.Palm Velocity
- The rate of change of Palm Position
, in Vuo Coordinates per second.Wrist Position
— The center position of the wrist, in Vuo Coordinates.Sphere Radius
- The radius of a ball that could be held by this hand, in Vuo Coordinates.Sphere Center
- The center of a ball that could be held by this hand, in Vuo Coordinates.Pinch Amount
— The degree to which the hand is performing a pinch pose, ranging from 1 (complete pinch) to 0 (no pinch). A pinch pose is when the thumb and the closest fingertip are brought together.Grab Amount
— The degree to which the hand is performing a grab pose, ranging from 1 (complete grab) to 0 (no grab). A grab pose is when the hand closes into a fist.Is Left Hand
- True if this is a left hand, false if it’s a right hand.Time Visible
— The time since this pointable was detected by Leap Motion, in seconds.Confidence
— The level of confidence that the hand and fingers have been correctly interpreted by Leap Motion, ranging from 1 (most confident) to 0 (not confident at all).Fingers
- The fingers attached to this hand, listed in arbitrary order. The list contains as many fingers as are detected by the Leap Motion.Sphere Radius
and Sphere Center
are based on a sphere calculated to fit the curvature of the palm and finger. It approximates the largest ball that the hand could hold in its current position.
