Subjective Impression of Reality Using Approaching Virtual Baton with Spin

Abstract

The purpose of this study was to investigate the observers' impression related to reality when they view an approaching baton with spin that is simulated in a virtual reality system. Twelve participants viewed the approaching virtual baton with no-spin and spin under monoscopic and stereoscopic display settings. They then rated their senses of stereoscopic effects, speed, dynamics, and discomfort on a visual analog scale. The results showed that the baton spin and the stereoscopic display setting enhanced the sense of a stereoscopic effect. The baton spin also increased the observers' sense of speed. Further, the stereoscopic display setting induced a higher sense of dynamics than the monoscopic display setting. These findings suggested that the impression related to reality for an approaching virtual baton was enhanced by the stereoscopic display and by the existence of spin in a virtual reality system.
