Abstract：
Many studies have shown that ergonomically designed furniture improves productivity and well-being. As computers have become a part of students\' academic lives, they will continue to grow in the future. We propose anthropometric-based furniture dimensions that are suitable for university students to improve computer laboratory ergonomics. We collected data from 380 participants and analyzed 11 anthropometric measurements, correlating them with 11 furniture dimensions. Two types of furniture were found and studied in different university computer laboratories: (1) a non-adjustable chair with a non-adjustable table and (2) an adjustable chair with a non-adjustable table. The mismatch calculation showed a significant difference between existing furniture dimensions and anthropometric measurements, indicating that 7 of the 11 existing furniture dimensions need improvement. The one-way ANOVA test with a significance level of 5% also showed a significant difference between the anthropometric data and existing furniture dimensions. All 11 dimensions were determined to match students\' anthropometric data. The proposed dimensions were found to be more compatible and showed reduced mismatch percentages for nine furniture dimensions and nearly zero mismatches for seat width, backrest height, and under the hood for both males and females compared to the existing furniture dimensions. The proposed dimensions of the furniture set with adjustable seat height showed slightly improved match results for seat height and seat-to-table clearance, which showed zero mismatches compared with the non-adjustable furniture set. The table width and table depth dimensions were suggested according to Barnes and Squires\' ergonomic work envelope model, considering hand reach. The positions of the keyboard and mouse are also suggested according to the work envelope. The monitor position and viewing angle were proposed according to OSHA guidelines. This study suggests that the proposed dimensions can improve comfort levels, reducing the risk of musculoskeletal disorders among students. Further studies on the implementation and long-term effects of the proposed dimensions in real-world computer laboratory settings are recommended.
摘要：
许多研究表明，符合人体工程学设计的家具可以提高生产率和幸福感。电脑已经成为学生学术生活的一部分,他们将在未来继续增长。我们提出了适合大学生的基于人体测量的家具尺寸，以提高计算机实验室的人体工程学。我们收集了380名参与者的数据，分析了11项人体测量，将它们与11个家具尺寸相关联。在不同的大学计算机实验室中发现并研究了两种类型的家具：（1）带有不可调节桌子的不可调节椅子和（2）带有不可调节桌子的可调节椅子。不匹配计算显示现有家具尺寸和人体测量之间存在显着差异，这表明11个现有家具尺寸中有7个需要改进。显著性水平为5％的单向ANOVA检验也显示了人体测量数据与现有家具尺寸之间的显着差异。确定所有11个维度以匹配学生的人体测量数据。Theproposeddimensionswerefoundtobemorecompatibleandshowedreducedmismatchpercentageforninefurnituredimensionsandnearlyzeromismatchforseatwidth,靠背高度,与现有家具尺寸相比，男性和女性的引擎盖下。座椅高度可调的家具组的建议尺寸显示，座椅高度和座椅至桌子间隙的匹配结果略有改善，与不可调节的家具组相比，显示零不匹配。表宽度和表深度尺寸根据Barnes和Squires'人体工学工作包络模型建议,考虑到手。键盘和鼠标的位置也根据工作范围建议。根据OSHA指南提出了监视器位置和视角。这项研究表明，建议的尺寸可以提高舒适度，降低学生肌肉骨骼疾病的风险。建议进一步研究在现实世界的计算机实验室环境中建议的尺寸的实施和长期影响。
