The objective of this study was to determine the match level of school furniture with student dimensions and conduct a pilot study to examine practicality of a computer-aided ergonomic analysis software with a Motion Capture System (MoCap) for the purpose of improving school furniture design process in terms of determining optimum dimensions. The research involved measuring the anthropometric data of 218 voluntary primary school students in Mugla, Turkiye and the dimensions of the existing school desks they use. The compatibility between the students' anthropometry and the existing school desks were analysed by using reference equations. Computer-aided ergonomic analysis performed only for seat and desk height. Four virtual human model and ten different school desks in various dimensions were created and evaluated according to joint reaction forces and muscle activations in three different postures by using Anybody Modelling System (AMS). The results of compatibility level showed that there were significant incompatibilities between the students' anthropometry and the existing school desks, with 80% of seat heights and 96% of desk heights being too high. Overall, in order to assess the optimal school desk dimensions, ergonomic analyses provided data indicating reduced joint reaction forces and muscle activations within the musculoskeletal system for the seat and desk height dimensions determined using reference equations. Also, the findings from the ergonomic analysis revealed valuable information on how even minor dimensional modifications to school desks can affect the musculoskeletal system. The study examined the impact of simulating student-school desk matching in various sizes and postures within a virtual environment using computer-aided ergonomic analysis software. The analysis focused on specific local areas of the musculoskeletal system to determine optimum school desk dimensions. The results indicated that the software has a potential in facilitating school furniture design based on user's anthropometric measurements. However, a multidisciplinary team is required to make more detailed analysis.
本研究的目的是确定学校家具与学生尺寸的匹配程度，并进行一项试点研究，以检验计算机辅助人体工程学分析软件与动作捕捉系统（MoCap）在确定最佳尺寸方面改进学校家具设计过程的实用性。该研究包括测量土耳其穆拉218名自愿参与的小学生的人体测量数据以及他们所使用的现有学校课桌的尺寸。通过使用参考方程分析学生人体测量数据与现有学校课桌之间的兼容性。仅对座椅和课桌高度进行了计算机辅助人体工程学分析。使用Anybody建模系统（AMS）创建了四个虚拟人体模型和十种不同尺寸的学校课桌，并根据三种不同姿势下的关节反应力和肌肉激活情况进行了评估。兼容性水平结果表明，学生人体测量数据与现有学校课桌之间存在显著不匹配，80%的座椅高度和96%的课桌高度过高。总体而言，为了评估最佳学校课桌尺寸，人体工程学分析提供的数据表明，对于使用参考方程确定的座椅和课桌高度尺寸，肌肉骨骼系统内的关节反应力和肌肉激活有所降低。此外，人体工程学分析的结果揭示了关于学校课桌即使是微小尺寸修改如何影响肌肉骨骼系统的有价值信息。该研究考察了使用计算机辅助人体工程学分析软件在虚拟环境中模拟不同尺寸和姿势下学生与学校课桌匹配的影响。分析聚焦于肌肉骨骼系统的特定局部区域以确定最佳学校课桌尺寸。结果表明，该软件在基于用户人体测量数据促进学校家具设计方面具有潜力。然而，需要一个多学科团队进行更详细的分析。
