Abstract

PURPOSE: Human posture is controlled by a combination of vestibular, somatosensory and visual information. This paper is concerned with postural readjustment responses induced by vection. In the visual control of posture, visually-induced perception of self-motion plays an important role and is called vection. Vection is difficult to measure quantitatively because it is a highly subjective phenomenon. HYPOTHESIS: An optokinetic stimulus that moves in depth induces vection. We hypothesize that the magnitude of the visually-induced body sway is correlated with the degree of vection. METHODS: A depth optokinetic stimulus (DOKS) was projected onto a head-mounted display (HMD) worn by standing subjects. The DOKS consisted of a random dot pattern that was perceived three-dimensionally and moved in depth sinusoidally. Vection was estimated in two ways, a verbal assessment and a joystick maneuver. In addition, visually-induced body sway was measured by monitoring five reference points on the body by two video-motion analyzers. RESULTS: The magnitude of the subjective vection was highly correlated with visually-induced body sway and was strongly dependent on the velocity of the visual stimulus. The ankle joint was pivoted during visually-induced body sway and acted as a motion initiator. When the magnitude of body sway was large, the body movement was adjusted at the hip and head-neck joints. CONCLUSIONS: The high correlation between vection and body sway suggests that vection can be estimated quantitatively by measuring visually-induced body sway.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Kuno et al. (1999) found that postural responses were observed immediately after participants reported vection, indicating a positive correlation between vection and postural sway and suggesting vection might precede or trigger postural sway.

    “Kuno et al. (1999) found that postural responses were observed immediately after participants reported vection, not only indicating a positive correlation between vection and postural sway, but also highlighting the temporal relation between the two concepts, suggesting that vection might precede or trigger postural sway”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
