Abstract
Sense of self-agency (perceived control) has been proposed in psychology field, and it is the sense that “I am the initiator or source of the action”. In this study, psychological experiments using a simple driving simulator, adding auditory information as one of multimodalities assumed support of visual processing, were conducted and then elicited how operator’s sense of self-agency changes corresponding to a degree of consistency between time-series waveforms of operation and of auditory information. The result suggested that noise and signal could be redefined from the view point of the sense of self-agency toward noise and vibration of vehicle-body design.
