A Novel 2D Photographic Approach for Measuring Range of Motion in Large-Scale Anthropometric Surveys

---

Abstract

Large-scale national anthropometric surveys provide essential data for ergonomic design; however, dynamic measures such as range of motion (ROM) are rarely included due to methodological constraints. This study evaluated the feasibility of 2D photography as an alternative ROM measurement method for large-scale surveys. Nine adults performed 16 industry-relevant dynamic postures, which were measured using 2D photography, goniometry, and a 3D scan–based vector method. Consistency, accuracy, and efficiency were compared using a dual-reference framework, with the goniometer as a clinical reference and the 3D vector as a technical quasi-reference. All methods demonstrated excellent reliability (ICC > 0.98), with 2D photography showing perfect inter-rater agreement. Whole-joint accuracy did not differ significantly among methods, indicating non-inferiority of 2D photography. Joint-specific differences were limited and reference-dependent. The 2D method required the shortest total time and received favorable subjective ratings across most evaluation items. The findings support 2D photography as practical, efficient, and scalable.
