Position, Posture, and Pose Definitions for 3D Body Processing

The interchangeable use of the terms position, posture, and pose causes confusion for 3D body processing (3DBP) applications. This paper reviews current definitions and contextual use of these terms to suggest standardized nomenclature for posture and pose. This paper also reviews and discusses possible standard definitions for location, body regions, landmarks, and anatomical relationships. With large language models being central to artificial intelligence (AI), standardized terminology is imperative to all digitization efforts. Replicating, or cloning of, actual posture is a known challenge inhibiting cloned human body models, optimized virtual try-on, and critical fit assessment. 3DBP applications need to be sophisticated enough to accept and utilize unique actual postures, in a given pose, which may vary drastically from a predetermined norm. The discussion builds off of current ISO standards to an open discussion for standards toward posture-improved human body models inclusive of widely varying morphology.
