这项研究描述了“视线水平”和“低”显示器位置对执行文字处理任务的受试者头部和颈部姿势的影响。将显示器降低到视线下方 18 度的位置对颈部相对于躯干的位置没有显着影响，而头部相对于颈部的平均弯曲增加了 5 度 (p = 0.024)。在“视线水平”条件下，平均凝视角度为耳眼线下方 17 度，而在“低”条件下，平均凝视角度为耳眼线下方 25 度。因此，降低显示器可以采用更接近首选的注视角度（耳眼线下方 35 度到 44 度之间的某个位置）。对头部和颈部生物力学的检查表明，“显示器顶部与眼睛高度相同”类型的建议必须受到质疑。与行业的相关性当前有关计算机显示器适当高度的建议更多地基于直觉，而不是经验证据。将计算机显示器放置在较低的位置可能会有所帮助。 (C) 1999 Elsevier Science B.V. 保留所有权利。
This research describes the influence of "eye level" and "low" monitor locations on the head and neck posture of subjects performing a word processing task. Lowering the monitor to a position 18 degrees below eye level had no significant effect on the position of the neck relative to the trunk, while the mean flexion of the head relative to the neck increased by 5 degrees (p = 0.024). In the "eye level" condition the mean gaze angle was 17 degrees below the ear-eye line, and in the "low" condition the average gaze angle was 25 degrees below the ear-eye line. Lowering the monitor thus allows gaze angles closer to that preferred (somewhere between 35 degrees and 44 degrees below the ear-eye line) to be adopted. An examination of head and neck biomechanics suggests that recommendations of the "top of monitor at eye height" type must be questioned.Relevance to industryCurrent recommendations regarding the appropriate height of computer monitors are based more on intuition than empirical evidence. Lower computer monitor placements may be beneficial. (C) 1999 Elsevier Science B.V. All rights reserved.
