通过观察和模仿人类运动来学习人类运动和运动控制机制的过程是基于三维空间中的视觉运动控制。然而，先前关于三维空间中视觉运动控制的研究主要集中于分析使用单关节或多关节运动沿一维线或二维平面的跟踪任务。因此，在本研究中，我们开发了一种基于虚拟现实（VR）环境的三维空间中视觉运动控制定量评估的新系统。我们提出的系统旨在以毫米级精度分析 VR 空间中额面和矢状面的圆形跟踪运动。特别是，我们比较了单目和双眼视觉条件下的圆形跟踪运动。结果表明，在额状面和矢状面上，单眼视觉的圆形跟踪运动的精度比双眼视觉下降约4.5倍。我们还发现，单眼和双眼视觉中，仅 X 轴的精度在额面和矢状面之间即可观察到显着差异。
The process of learning a human’s movement and motor control mechanisms by watching and mimicking human motions was based on visuo-motor control in three dimensional space. However, previous studies regarding the visuo-motor control in three dimensional space have focused on analyzing the tracking tasks along one-dimensional lines or two-dimensional planes using single or multi-joint movements. Therefore, in this study, we developed a new system to quantitatively evaluate visuo-motor control in three-dimensional space based on virtual reality (VR) environment. Our proposed system is designed to analyze circular tracking movements on frontal and sagittal planes in VR space with millimeter level accuracy. In particular, we compared the circular tracking movements under monocular and binocular vision conditions. The results showed that the accuracy of circular tracking movements drops approximately 4.5 times in monocular vision than that in binocular vision on both frontal and sagittal planes. We also found that significant difference can be observed between frontal and sagittal planes for only the accuracy of X-axis in both monocular and binocular visions.
