摘要
以视平线可与显示器中心重合为准,分别探讨显示器中心在视平线上方、下方时不同视距对头部关节舒适度的影响。实验自变量为视距(眼睛与显示器中心的水平距离),因变量为头部关节舒适度。实验结果显示:1)显示器中心在人视平线上方时,头部舒适性状态始终处于不舒适状态,此时视距与人的头部舒适性关系成正比,即视距越大,头部舒适性越好;2)显示器中心在人视平线下方时,头部关节舒适状态始终处于正常范围,舒适性程度随视距增大而减小。
Defining the eye level coincides with the center of the display as a reference, the paper explores the influence of different visual distance to head joint comfort when the computer display center below/above the eye level. Experimental variable is visual distance （the visual distance between the eyes and display center）. The dependent variable is head joint comfort. The experimental results show： （ 1 ） when the computer display center above the eye level, the head comfortable state is always in the uncomfortable（yellow） state; visual distance is proportional to the head of the human comfort, that is the bigger visual distance, the better humanb head com- fort. （2）When the computer display center below the eye level, the head comfortable state is always in the nor- mal （green） state, the bigger visual distance, the less humang head comfort.
