Gives information about a hand detected within a frame from a Leap Motion device.
id
- A unique ID for this hand.direction
- A unit vector pointing from palmPosition
toward the fingers.palmNormal
- A unit vector pointing outward from (perpendicular to) the front surface of the palm.palmPosition
- The center of the palm, in Vuo coordinates.palmVelocity
- The rate of change of palmPosition
, in Vuo coordinates per second.sphereRadius
- The radius of a ball that could be held by this hand, in Vuo coordinates.sphereCenter
- The center of a ball that could be held by this hand, in Vuo coordinates.pointables
- A list of all pointables (fingers and tools) attached to this hand.sphereRadius
and sphereCenter
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.
