A study of causality between the property of recognition and perception of the object movement and acquisition error in using virtual reality technology

本研究采用虚拟环境中运动物体遮挡后的位置预测任务进行。被试对被遮挡运动物体的速度（预期速度）的估计比实际速度慢（预期速度减慢现象）。由于这是影响对运动物体反应的重要因素，讨论了这一现象产生的原因和预期特性。从眼动分析来看，预期速度的减慢可能是由于遮挡引起的，并且应答物体位置的信息处理可能会影响预期速度。400次学习任务的结果表明，预测属性的学习过程由位置误差校正进入速度校正阶段。这表明，通过反复训练，预期技能有可能得到提高。

This study was carried out by using tasks of position anticipation of moving object after occlusion in virtual environment. Subjects estimated the velocity of occluded moving object (anticipated velocity) slower than the actual one (anticipated velocity slowdown phenomenon). As it was an important factor which influences the reaction to the moving object, the cause of this phenomenon and the anticipation property were discussed.From the analysis of eye movement, it was suggested that the anticipated velocity slowdown would be caused by occlusion and the possibility that the information processing to answer the object's position influenced anticipated velocity. The result of 400 times learning tasks showed that the learning process of the anticipation property changes from location error correction into velocity correction stage. This suggested the possibility that the anticipation skill would be improved by repeated training.
