The effect of viewing a virtual environment through a head-mounted display on balance

Analysis of Stability on Single-leg Standing by Wearing a Head Mounted Display

“…In addition, they reported that the virtual setting had no difference in the frontal, lateral, and total COP between the EO and EC states, and similar results have been reported in a study by Chiarovano et al (2015). In the present study, the visual representation of the VR was constructed in the same manner as in the EO state; however, our results were more similar to those of Horlings et al (2009) than to those of Robert et al (2016) and Chiarovano et al (2015).…”

“…However, Robert et al (2016) argued against the study by Horlings et al (2009), because it was difficult to directly compare the two settings owing to the absence of a similar visual representation and expression of a smaller visual field than the VR HMD. Instead, Robert et al (2016) compared COP based on the difference between real and virtual settings.…”

“…This VR effectively controls movements with various and immediate feedbacks and induces interests and amusements, leading to active performance of the task (Chan et al, 2010;Kizony et al, 2004;Rizzo & Buckwalter, 1997). In recent years, lightweight helmets and head mounted displays (HMDs) have improved immersion in three-dimensional (3D) environments through 360° viewing angles with low-cost VR systems (Robert et al, 2016;Schubert et al, 2001). …”

“…between the ability of static posture and muscle activity through HMD, and Kim et al (1996) conducted a study on balance control through visual stimulation through VR, by using HMD in Korea for the first time. Kim et al (2017) assessed the stability of VR gait training with HMD for elderly patients with Parkinson's disease, and Robert et al (2016) evaluated the effects of HMD wearing in a virtual setting created from images of reality on static and dynamic balance. Mustonen et al (2013) used monocular HMDs to investigate the effects of gait on visual tasks; Berard et al (2012) analyzed the abilities of elderly and young subjects in processing sensory information during walking depending on speed and visual perturbation in the HMD wearing state; and Lott et al (2003) validated the effects of uses of flat-screen and HMD VR.…”
