摘　　要：刻度带是重要的显示信息之一。为研究振动对人眼辨识刻度带信息的影响,本文开展了在被试不动刻度带振动的情况下振动对人眼视觉绩效的影响实验。试验人员在水平和垂直方向振动下,完成了一种振幅(1.6mm)和四种频率(5,10,15,20Hz)条件下的三种刻度带(水平,竖直,扇形)辨认任务。实验以被试完成视觉任务所需反应时间和正确率为视觉绩效指标,并利用李克特量表评估不同振动条件下被试完成视觉任务的视觉舒适度。研究结果表明,振动频率对反应时、正确率和视觉舒适度都有显著影响(p<0.05);振动方向对视觉舒适度和视觉绩效中的辨识反应时有显著影响(p<0.05);刻度带形式对反应时、正确率和视觉舒适度都有显著影响(p<0.05)。振动频率超过10Hz时,随着振动频率的升高,观察反应时迅速增加,正确率持续降低;相比于纵向振动,横向振动影响更大,在横向振动条件下观察反应时增加了近100ms;在振动条件下被试对刻度带的观察能力纵向刻度带最差,横向刻度带次之,扇形刻度带最好。The scale belt is one of the important display information.In order to study the influence of vibration,an experiment to test the influence to observation ability of vibration is carried out in this paper.Under horizontal and vertical vibration,the test completed three kinds of scale（ horizontal,vertical,sector） identification tasks under the condition of four kinds of frequency（ 5,10,15,20Hz）.Experiments were done to test the response time and accuracy of the visual task to the visual performance,and to evaluate the visual comfort level of the visual task with the Likert scale.The results show that the vibration frequency has a significant effect on the response time,accuracy and visual comfort（ p 0.05）.The vibration direction has significant effect on the visual comfort and visual performance（ p 0.05）.When the vibration frequency is over 10 Hz,with the increase of the vibration frequency,the rate of the reaction is increasing rapidly,and the accuracy is decreasing.Compared to the vertical vibration,the effect of horizontal vibration is bigger,and the reaction time increased 100 ms.In the vibration condition,the observation ability of the vertical scale is the worst,and the horizontal scale is the best.
