Effect of Background Viewing on Equilibrium Systems
Our previous study indicated an increase in the sway values that were observed during peripheral viewing. Especially in the background, there are large differences between human binocular images and artificial stereoscopic images, to which our convergence corresponding to depth cues is not accommodated. This is why equilibrium functions are affected by peripheral viewing. In the present paper, we examine the effect of the exposure to stereoscopic video clips without the background on our equilibrium function. Fifteen healthy young males voluntarily participated and maintained the Romberg posture in stabilometry. Their stabilograms were recorded during monocular vision or binocular parallax vision using semipermeable smart glasses. We also measured the body sway with the subjects’ eyes closed 0–3 min after the exposure to the video clips. A statistical comparison indicated that our equilibrium function is significantly affected by video clips with the background 0–2 min after the exposure to the video clips.
