摘要

HMDs and their integration into military systems have greatly improved. However, a significant issue with HMDs is the effect of vibration and the Vestibulo-Ocular Reflex (VOR). When a human's head is subject to low- frequency vibration, the VOR stabilizes the eye with respect to the external environment. However this response causes blurring of an HMD display as the system moves with the user's head. This research sought to understand the VOR as a function of whole body low-frequency vibration. An experimental HMD was developed to allow a user to perform visual tasks, while also recording eye movements via video recording and EOG. A human subject experiment was executed to collect data on vibration effects on eye movement while performing tasks chosen to isolate specific eye motions. The results indicate that during fixation on a stationary target, the magnitude of eye movement was greatest at 4-6 Hz. The addition of motion to this target significantly increased the magnitude at this range. The findings are consistent with previous research which has found a decline in visual performance at 4-6 Hz.
