摘要：Multimedia users all over the world hope to experience more natural and realistic audio–visual contents such as landscapes, music, and sports. This study investigated whether sounds and playback speeds of sports video (a golf swing scene) were able to modify viewers' perceived sense of presence and verisimilitude. Previous studies revealed different characteristics between the sense of presence and verisimilitude during perception of audio–visual contents. For this study, we recorded a video of the golf swing scene with a high-speed camera and manipulated the playback speeds and impact sound of the video for use as experimental stimuli. Results showed that the sense of presence was increased when the scene was presented at normal playback speed with or without sound conditions. In contrast, verisimilitude showed different patterns with respect to the playback speeds between these sound conditions. Our findings indicate that viewers' sense of presence and verisimilitude have different sensitivity to the contingent sounds and different temporal characteristics.
