Abstract
Head Mounted Display (HMD) is a virtual reality device worn on the head
with a display covering the eyesight. The HMD has promising applications in
various areas and it is leading towards a drastic makeover of the virtual reality
industry. However, many users have reported discomfort associated with dizziness
and diplopia yet the unidentified mechanisms of these side-effects remain the
biggest hurdle to overcome. Since disruptions in sensory information processing
occurs in virtual environments, investigating the neurological mechanism in HMD
use may give fundamental guidelines for this potential threat.
The present study investigated the effects of the visual and oculomotor
determinants such as vergence-accommodation linkage and interocular torsional
disparity in HMD use. Thus, physiological symptoms such as the pulse rate and
center of pressure (COP) were measured, and the Simulator Sickness Questionnaire
(SSQ) data were collected to clarify the factors underlying side-effects. Empirical
validation of the effect of each factor was conducted using the biomarkers.
By considering such neurological mechanisms in vision, the present results
suggest a possible approach to reduce visual discomfort and side effects occurring
via HMD.
