摘要
针对振动对视觉识别的干扰,实验研究了振动方向、频率、振幅以及识别对象特征对视觉识别效率(正确识别速度)的影响。根据实验数据,给出了不同振动频率和不同振幅下的识别效率函数,揭示了振动特征与识别对象特征对识别效率的影响及其交互作用。实验结果表明,随着振动频率或振幅的增加,识别效率呈指数趋势递减;振动频率、振幅和识别对象特征对视觉识别效率有显著影响;频率与振幅、振动方向与识别对象特征的交互作用显著。实验结果为振动工况下视觉显示的识别可靠性与舒适性设计提供了依据。
Aiming at the vibration interference on visual identification,the effects of vibration on vi- sual identification efficiency （correct identification speed）were researched through simulation experiment. Based on the experimental data,it gained the identification efficiency funetion under different frequency and amplitude,revealed the influence of vibration and target characters on identification efficiency and their interaction.The experiment results indicate that：identification efficiency decreases exponentially with the increasing of vibration frequency or amplitude ;the frequency, amplitude and target characters have a significant influence on identification efficiency;the interactions of frequency with amplitude ,vibration di- rection with target characters are significant.This would provide a basis for the identification reliability and comfort des ign of Visual Display Terminals（VDT）under vib ration operating situation.
