The effects of active head rotation on the vestibulo-ocular reflex during visual pursuit of a target displayed on the integrated helmet and display sight subsystem

Title The Effects of Active Head Rotation on the Vestibulo-Ocular Reflex During Visual Pursuit of a Target Displayed on the Integrated Helmet and Display Sight Subsystem The goal of this study was to determine whether active head rotation could suppress the vestibulo-ocular reflex (VOR) and to examine the effects of VOR suppression on night-aided helicopter flight. Ten participants performed a series of active head rotation tasks designed to establish a baseline VOR measurement in the control condition, and to suppress the VOR in the experimental condition. The results of the active head rotation tasks revealed that the VOR was not significantly reduced in the experimental condition. Thus, the effects of VOR suppression on night-aided flight could not be determined. Future research will be aimed at minimizing potential sources of error variance to determine whether active head rotation is capable of reducing the VOR.
