Abstract

Weighted integration of visual and proprioceptive information is important in movement planning and execution. The present study used a virtual reality system to determine how upper limb movement consistency and accuracy are altered when (a) vision of the limb is removed and (b) proprioception and vision of the limb are misaligned. A one degree of freedom upper limb movement task was performed under three visual conditions of the limb; accurate vision, no vision, and offset vision. Movement consistency was unaltered by the change in visual condition. Compared to the accurate vision condition, movement accuracy was unchanged in the no vision condition but decreased with a visual offset. When available, vision was relied upon more heavily than proprioception for task completion.

关节位置精度受虚拟现实中视觉本体的一致性影响

摘要

视觉和本体感觉信息的加权整合在运动规划和执行中很重要。本研究使用虚拟现实系统来确定当 (a) 肢体的视力被移除和 (b) 肢体的本体感觉和视力未对齐时,上肢运动的一致性和准确性如何改变。在肢体的三种视觉条件下执行一个自由度上肢运动任务;准确视力、无视力和偏移视力。视觉条件的变化不会改变运动的一致性。与精确视觉条件相比,无视觉条件下的运动精度没有变化,但随着视觉偏移而下降。在可用的情况下,完成任务更依赖视觉而不是本体感觉。
