Human Factors of LCD Displays in Motion Environment-Reading Accuracy and Visual Fatigue
LCD displays are widely used in vehicles today. The placement of the display in moving vehicles is subject to many Kinds of vibration. It is disturbing and annoying when human eyes have to read and precisely identify targets subject to a certain range of frequency and magnitude of vibration. The reading performance may be decreased and visual discomfort and fatigue may result. This study tested these two hypotheses by studying the effect of different vibration conditions (vibration frequency, vibration amplitude, and different direction of vibration) on visual task for several different designs of vertically displayed numerical characteristics which include the font size and the number of digits on the LCD display. The visual perfonnance and fatigue were measured by the reaction time, accuracy, critical flicker fusion frequency, visual acuity, and subjective evaluation. The results showed that both the frequency and magnitude of vibration had significant effects on the reaction time, accuracy, and visual fatigue. The software design of the displayed materials must take the motion effect into consideration to increase the quality of the screen display.
