Exploring User-Specific Variations in Vestibular Stimulation to Reduce Motion Sickness in Virtual Reality

Motion sickness is regarded as one of important limitations in Virtual Reality (VR) applications. This study investigates the effects of vertical vibrations and additional rotational vestibular stimulation on alleviating discomfort and enhancing immersion. We conducted pilot and main studies to examine the threshold of stimulation intensity to reduce motion sickness. Experimental results revealed that the effect of vestibular stimuli varied based on user characteristics such as gender, age, and vision, highlighting the need for personalized stimulation. The initial findings offer suggestion for developing more comfortable and immersive VR experiences.
