Recommendations to Reduce Cybersickness in Virtual Reality Based on User’s Personality and Eye Health

Abstract

The use of Virtual Reality (VR) technology is closely related to Cybersickness (CS), namely a feeling of
dizziness that arises due to differences in perception between what is felt and seen. Other research show
that personality and eye health can affect a person's perception thus affecting the level of CS felt. The study
aims to identify the relationship between personality and eye health on CS and make recommendations to
reduce for gaming industries. The research was conducted with within-subject experimental design with two
variables, personality and eye health. The initial study made an experimental design which was followed by
a pilot study to determine the minimum sample size for the study and improvements to the experiment.
Furthermore, participant data was collected in the form of personality, eye health, completion time, and
Virtual Reality Sickness Questionnaire (VRSQ) score. Data was collected from 36 participants and then
processed statistically. The data were tested for classical assumptions and searched for their relationship with
the two-way ANOVA. After knowing the existence of a relationship, a Post-hoc Test (Tukey's Test) was
conducted to find the most significant group. The results shows that there was a significant relationship
between personality and eye health on CS (P-Value < 0.05), where participants with introvert personality
and abnormal eye conditions are more vulnerable. From the results of the study, it is recommended that
settings be made to reduce screen shakes, limit playing time, choose the right game, and do oculomotor
exercises before playing.
