我们进行了初步的眼睛和头盔显示器(HMD)运动测量，以收集原始数据，以创建时空虚拟现实(VR)导航系统。此外，我们使用Vive Pro Eye HMD的眼睛跟踪功能来测量HMD在凝视VR标记时的眼睛和旋转运动。通过测定凝视轨迹的Hurst指数和各向异性，比较了定点凝视和随机弹跳直线运动以及水平和垂直运动的差异，结果表明，固定视觉和慢速标记追逐的运动轨迹的Hurst指数均小于1/2，表现出反持续性。相反，随着标记速度的增加，注视轨迹的位移被拉伸，并表现出对标记运动方向的持久化。随着标记器速度的降低，注视轨迹垂直于标记器的运动方向扩展，提示反持续性微缩运动增强了视觉信息的收集。用户被发现无意识地将头盔显示器的持续运动叠加在水平方向的凝视运动上。我们推断，这种倾向有助于产生微型凝视运动来收集视觉信息。
We conducted preliminary eye and head mount display (HMD) movement measurements to collect primary data to create a spatio-temporal virtual reality (VR) navigation system. Furthermore, we used the eye-tracking function of the Vive Pro Eye HMD to perform eye and rotational movement measurements of the HMD when gazing at a VR marker. We compared gazing at a fixed point with randomly bouncing linear motion along with horizontal and vertical motion by determining the Hurst exponent and the anisotropy of the gaze trajectories.Trajectories of the fixed vision and the slow marker chasing showed the Hurst exponent less than 1/2, indicating anti-persistency. In contrast, as the marker velocity increased, the displacements of gaze trajectories were stretched and showed persistency to the marker motion direction. As the marker speed decreased, the gaze trajectory expanded perpendicular to the marker motion, suggesting that the antipersistent miniature motion enhanced the collection of visual information. Users were found unconsciously superimposed a persistent motion of HMD on the gaze motion in the horizontal direction. We inferred this tendency to help to generate miniature gaze motion to collect visual information.
