今日交通工具中广泛使用液晶显示萤幕,荧幕也随着各式各样的振动对人产生影响。尤其人们眼睛在阅读精确的文章时,振动所造成不适,影响就变得更剧烈,因此容易造成阅读绩效不佳与视觉不适。本研究想要探讨液晶萤幕在不同振动情形(振动频率、振动振幅与不同振动方向)对数字大小、数字多寡与数字排列之影响。阅读绩效与视觉疲劳的量测为反应时间、正确率、闪光融合阈值、视力变化与主观评量,由实验得到频率对反应时间、正确率与视觉疲劳有显著的影响。因此荧幕硬件与软件之设计必须考虑到振动的影响。
Today’s vehicles are widely used in liquid crystal display screen, the screen also has a wide range of vibration on the human impact. Especially in the eyes of people reading accurate articles, the discomfort caused by vibration, the impact becomes more intense, so easily lead to reading poor performance and visual discomfort. In this study, we wanted to investigate the influence of LCD screens on numbers, numbers, and numbers in different vibration scenarios (vibration frequency, vibration amplitude and different vibration directions). Reading performance and visual fatigue were measured as reaction time, correct rate, flash fusion threshold, visual acuity and subjective assessment. The experimental results showed that the frequency had a significant effect on the reaction time, accuracy and visual fatigue. Therefore, the design of the screen hardware and software must take into account the impact of vibration.
