Summary

Visually-induced perception of self-motion, known as vection, can be quantitatively measured by analyzing body sway. This study demonstrates a strong correlation between vection magnitude and body sway responses.

Background:

Human posture relies on vestibular, somatosensory, and visual inputs.
Vection, the visually-induced perception of self-motion, is crucial for visual posture control but difficult to quantify.
This study investigates vection's role in postural readjustment.

Purpose of the Study:

To test the hypothesis that visually-induced body sway magnitude correlates with vection.
To explore quantitative methods for assessing vection.

Main Methods:

Subjects experienced depth optokinetic stimuli (DOKS) via a head-mounted display.
Vection was assessed through verbal reports and joystick control.
Visually-induced body sway was measured using video-motion analysis.

Main Results:

Subjective vection magnitude strongly correlated with visually-induced body sway.
Body sway was dependent on visual stimulus velocity.
Ankle joints initiated sway; hip and head-neck joints adjusted larger movements.

Conclusions:

Vection can be quantitatively estimated by measuring visually-induced body sway.
This finding offers a more objective method for assessing vection.
