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.
