Method of Creating Video Content that Cause The Sensation of Falling

In recent years, video content that enables users to experience a simulated fall using an head mounted display (HMD) has become popular. However, the visual factors that cause the sensation of falling have not been clarified. In this study, we focused on visual stimuli, which are known to affect the intensity of vection, and examined their relationship to the sensation of falling.The results confirmed that stimulus presented from the peripheral visual field area and increased spatial frequency amplified the sensation of falling. In addition, we were able to produce video content that produced a greater sense of falling by using multiple visual stimuli that had the property of increasing vection.
