Today electronic visual displays have dramatic use in daily life. Reading these visual displays is subject to their vibration. Using a software-simulation of a vibrated environment, the study investigated the effect of vibration on visual performance and fatigue for several numerical display design characteristics including the font size and the number of digits displayed. Both the frequency and magnitude of vibration had significant effects on the reaction time, accuracy, and visual fatigue. 10 graduate students (23-30 years old; M = 25.6), randomly tested in this experiment, were offered about 25 U.S. dollars for their participation. Numbers in vertical presentation were affected more in vertical vibration than those in horizontal presentation. Analysis showed whenever the display is used in vibration environment, an increased font size may be an effective way to compensate the adverse effect of vibration. The software design of displayed materials must be designed to take the motion effect into consideration to increase the quality of the screen display.
如今，电子视觉显示器在日常生活中有着广泛应用。阅读这些视觉显示器会受到其振动的影响。该研究利用振动环境的软件模拟，针对包括字体大小和显示数字数量在内的多种数字显示设计特征，探究了振动对视觉性能和疲劳的影响。振动的频率和幅度对反应时间、准确性和视觉疲劳均有显著影响。本实验随机测试了10名研究生（年龄在23至30岁之间；平均年龄为25.6岁），他们因参与实验获得了约25美元报酬。垂直呈现的数字在垂直振动时比水平呈现的数字受到的影响更大。分析表明，只要显示器在振动环境中使用，增大字体大小可能是补偿振动不利影响的有效方法。显示材料的软件设计必须考虑运动效果，以提高屏幕显示质量。
