The effects of VDT resolution on visual fatigue and readability were studied. Two kinds of displays with different resolutions (1664 x 1200 pixels and 720 x 350 pixels) and fonts were used. In the first experiment, the subjects read from each display for 1 h to induce fatigue. Reading speed and blink rate while reading were measured. Eye movements during visual smooth pursuit tracking tasks were studied before and after reading; quantitative scoring of eye movement performance showed no significant changes. In the second experiment, readability tests with three different character sizes on both displays were conducted and resulting reading eye movements were analysed. For readability of sufficiently large characters, no significant difference between the high and the standard VDT could be detected. However, for very small characters, higher resolution improved readability.
研究了视频显示终端（VDT）分辨率对视觉疲劳和可读性的影响。使用了两种具有不同分辨率（1664×1200像素和720×350像素）和字体的显示器。在第一个实验中，受试者从每个显示器上阅读1小时以诱发疲劳。测量阅读时的阅读速度和眨眼率。在阅读前后研究视觉平滑追踪任务期间的眼动；眼动性能的定量评分显示无显著变化。在第二个实验中，在两个显示器上对三种不同字号进行可读性测试，并分析由此产生的阅读眼动。对于足够大的字符的可读性，高分辨率和标准分辨率的VDT之间未检测到显著差异。然而，对于非常小的字符，更高的分辨率提高了可读性。
