Temporal characteristics of perceived reality of multimodal contents

Understanding the mechanism related to how people perceive reality is crucially important for the development of high-definition communication systems in multimedia contents. Various sensory information is well known to affect perceived reality from multimodal contents. For this purpose, it is important to present multimodal information with proper timing. This study investigated temporal characteristics of perceived reality induced by multimodal contents including vibration information. Results indicate that temporal characteristics of perceived reality depended on the timing of the events in the content, e.g. the timing with which the train just passes through an observation point. Moreover, the sense of presence was more sensitive to the timing of the presentation of sensory information with long contents.
