Abstract
A common technique for reducing VR sickness is image ingenuity. However, ingenuity based on images is not effective for phenomena such as attacks from blind spots. In this study, we focused on reducing VR sickness due to sound. Previous studies have shown that presenting a sound stimulus 600 ms earlier than a light stimulus results in a faster response time to subsequent events and reducing sickness by allowing the player to predict the events that will occur in advance. Therefore, we conducted a verification experiment using content that plays sound 600ms faster and content where video and sound are synchronized when a collision occurs from a blind spot when moving in a VR game. The evaluation by SSQ showed that there was no significant difference, but that presentation of sound stimuli tended to reduce sickness, and that various trends were clarified.
