Timing of Vibratory Stimuli to the Upper Body for Enhancing Fear and Excitement of Audio-visual Content

抄録

Vibratory stimuli to viewers’ upper bodies enhance emotional experiences during audio-visual content. Studies have investigated the effects of stimulation conditions, such as vibration waveform and spatiotemporal patterns. We investigated how the timing of vibratory stimuli affect viewers’ skin conductance responses and subjective reports of audio-visual experiences. Vibratory stimuli were administered to the viewers’ torso at various timings around a monster’s sudden appearance in horror videos, and jump performances in figure skating videos. For horror videos, vibratory stimuli elicited fear. The fear of horror videos was maximized when the vibratory stimuli started simultaneously with the monster’s first appearance. For the jump performance scenes in figure skating videos, although the most exciting timing varied by participant, the vibration should be intensified as performers launch off the ice. These findings will help develop entertaining audio-visual content.
