palmorientation
Palmorientation is the direction in which the palm surface faces, a fundamental parameter in anatomy, kinesiology, gesture analysis, and sign languages. It describes how the hand is oriented relative to the forearm and body, and it changes with forearm rotation and wrist position. In everyday anatomy, palm orientation is often discussed using the terms supination and pronation.
In anatomical terms, supination occurs when the forearm rotates so that the palm faces anteriorly or upward
In sign languages, palm orientation is a phonological parameter that helps distinguish signs. Orientation can be
Measurement and representation of palmorientation are typically done through observational coding, motion capture, or sign-language annotation
