handedness
handedness:
number
Classification score of handedness
Number between -1 and 1 that represents handedness. Negative value signals right hand, positive - left. Bigger magnitude (absolute value) means more rebust classification, the closer value is to zero - the more ambiguous is distinction of the handedness.

PhalanxDetection[]
List of phalanxes
Phalanx detection defines the center point and two points of corresponding edges at the same section.

HandPoint[]
List of hand keypoints
2D pixel coordinate - point in the screen coordinate space. XY coordinates are normalized screen coordinates (scaled by image width and height), while the Z coordinate is depth in orthographic projection space, it has the same scale as X. 3D metric coordinate - point within 3D space of perspective camera located at the space origin and pointed in the negative direction of the Z-axis. 3D & 2D points are perfectly aligned.

Reliability score, number between 0 and 1

optionalwrist:WristDetection
Wrist detection
Wrist detection provides 3 lines in screen coordinate space. Middle line defines 2D wrist center and unit direction vector of the wrist. Two wrist edges are defined by 2D points at the end of the wrist along transversal section through the center.
