VDT字符点阵尺寸对汉字显示清晰度的影响

The Effects of VDT Dot Matrix Size on Legilility

本研究以判读错误率和主观评价为指标研究了七种 VDT 汉字点阵显示尺寸(9×9、12×12、12×15、15×15、15×20、24×24、50×50)的视觉清晰度。结果表明:(1)点阵尺寸和每笔划点行数共同影响汉字显示的清晰度,清晰显示汉字的最小点阵尺寸为12×15或15×15;(2)汉字的笔划数和斜笔划率对清晰度有一定的影响.

This experiment studied the legibilities of seven types of VDT dot- matrix display sizes(9×9,12×12,12×15,15×15,15×20,24×24,50 ×50)for Chinese characters by using the indicators such as recognition error rate and subjective assessment.The main results were as follows: (1)12×15 or 15×15 was the minimun dot-matrix size to ensure the legibility of Chinese characters with one live per stroke. (2)The number of strokes and the oblique stroke ratio of Chinese characters affected the legibility.
