摘要:
为了研究假体佩戴者对于目标物体的运动感知,利用Unity搭建虚拟仿真假体视觉场景,利用遮挡范式下对碰撞时间的估计,探究不同运动方向、运动速度、运动方式、目标物体形状、环境对比度以及各因素下的性别差异对仿真假体视觉下的运动感知的影响。试验结果表明,被试者对于水平方向上的估计要比垂直方向上的估计更准确;对于快速运动的估计准确度要优于相对慢速运动物体的准确度;运动方式因素对估计影响无显著性差异;相同形状下,物体越大,被试者估计的准确性越高且对多角图形的运动比圆润图形的运动更加敏感;不同环境对比度对估计也具有显著性差异;性别对于估计无显著性影响,但不同因素下的结果有区别。
Abstract:
Abstract: Avirtual simulation scene for visual prosthesis is built by Unity for studying the motion perception of the wearer to target object, and the effects of motion direction, motion speed, motion mode, target object shape, environmental contrast level, and gender differences in various situations on the motion perception in simulated prosthetic vision are explored through the estimation of the time to collision. The experimental results showed that subjects estimation in the horizontal direction is more accurate than the estimation in the vertical direction, and that the estimation accuracy for fast motion is better than the accuracy for relatively slow motion.There is no significant difference in the effect of motion mode on the estimation. In the same shape, the larger the object is, the higher the accuracy of the subjects estimation is, and the subjects are more sensitive to the motion of polygonal graphics than round graphics. The estimations at different environmental contrast levels are significantly different. Gender has no significant effect on the estimation, but the results in various situations are different.
