基于视觉显示终端的人因工程分析研究

Human Factors Engineering Research Based on Visual Display Unit

针对不同规格的视觉显示终端，为满足人因工程要求，其显示的字体高度及图符大小应有所不同。通过分析视觉显示终端点距、分辨率等物理特性参数，推导出适用于视觉显示终端的人因分析方法及其计算公式。最后给出目前常用的视觉显示终端上满足人因要求的最小的字体高度和图符大小要求。

To meet the HFE （human factors engineering ） requirement ,the character height and graphic symbol size should be chosen differently from the size of the visual display unit where to be displayed .From analyzing the physical characteristic of the visual display unit ,and dot pitch and resolution ,the HFE analysis methods and corresponding formulas were derived .And the minimum character height and graphic symbol size for common visual display units were calculated and provided .
