The essential role of optical flow in the peripheral visual field for stable quiet standing: evidence from the use of a head-mounted display

Creator/Principal investigator(s):

Kentaro Horiuchi - Tokyo Metropolitan University

Description:

It has long been thought that vision is the most essential factor in maintaining stable quiet standing
compared to other sources (i.e., vestibular and somatosensory inputs) of information. Specifically, several vision studies on postural control have shown evidence for the importance of the visual system,particularly peripheral vision rather than central vision, and optical flow. Nevertheless, to date, no study has manipulated both visual field and optical flow concurrently. In the present study, we experimentally manipulated both the visual field (the central and peripheral visual fields) and the occurrence of optical flow during quiet standing, examining the effects of the visual field and optical flow on postural sway measured in terms of the center of pressure (CoP). Stationary random dot stimuli were presented exclusively in either the central or peripheral visual field, while the occurrence of optical flow was manipulated using a desktop (DTD) or a head-mounted (HMD) display. The optical flow that occurred while using the DTD was a function of the postural sway during quiet standing, whi

Description:

The data contains five CoP variables (Envelopment area, rectangular area, rms area, total CoP trajectory and total CoP trajectory per area). Each set of variables is presented for two display conditions and four visual field conditions. See Horiuchi et al. (2017) for details.
