Abstract
Helmet Mounted Displays (HMDs) and their integration into military systems have greatly improved. However, previous research has demonstrated degraded visual performance when an HMD user is subject to whole-body, low-frequency vibration. This effect has been attributed to the effect of the Vesitbular-Ocular Reflex as it stabilizes the eye with respect to the external environment, causing eye movement with respect to the HMD. This research sought to understand the VOR as a function of whole-body, low-frequency, z-axis vibration. A human subject experiment was executed to measure the effect of whole-body, low-frequency vibration on eye movements recorded with Electro-oculagraphy (EOG) while performing visual fixation tasks on an HMD. The results indicate that during fixation on a stationary target, the magnitude of VORdriven eye movement was greatest for a vibration frequency range of 4-6 Hz. The findings are consistent with previous research in visual performance.
