数控设备显示器上的汉字文本阅读工效研究

Reading Efficiency of Chinese Character on CNC Equipment Displays

目的研究影响电子显示器上汉字文本阅读工效的因素并提出建议。方法借鉴人机工程学经典理论,采用正交实验法,以数控机床显示器为对象、office word为载体,研究在显示器上进行单行和多行汉字阅读行为时字号、字距和行距对阅读工效的影响,并通过阅读速度、正确率和眼动指标来衡量阅读工效。结果在单行文本阅读中,最佳工效组合为字号12 pt、字间距2 pt;在多行文本阅读中,最佳工效组合为字号12 pt、字距2 pt、行距20 pt。结论研究得到的结果能为数控机床显示器、自助服务终端等类似机械设备上汉字格式的设置提供有效依据,让操作者能快速准确地理解和掌握文本信息,避免误操作。

It aims to research the factors that affecting the reading efficiency of Chinese text on electronic display and provide the best setting suggestions. Take CNC equipment displays as the research object and office word as the carrier, use the classical theory of ergonomics for reference and orthogonal experiment method to research how the word size, word space and line space affecting the reading efficiency when reading in single line and in multiple lines on electric displays, and evaluate the reading efficiency by reading speed, reading accuracy and eye movement index. The results show that the best efficiency combination in single line reading is 12pt in word size, 2pt in word space; in multiple lines reading is 12pt in word size, 2pt in word space, and 20pt in line space. The results of the research would provide effective basis for Chinese format setting in CNC machine, self-service termination, or other similar machine equipment, which would let operators understanding and mastery text information quickly and accurately, also prevent the faulty operations.
