The entertainment industry frequently uses vibroacoustic stimulation, where chairs with embedded loudspeakers and shakers enhance the experience. Scientific investigations of the effect of such enhancers on illusory self-motion (vection) and spatial presence are largely missing. The current study examined whether auditory-induced vection (AIV) may be further augmented-by the simultaneous presentation of additional vibrotactile cues delivered via mechanical shakers and low-frequency sound. It was found that mechanically induced vibrations increase AIV and spatial presence responses significantly. This cross-modal enhancement was stronger for stimuli containing an auditory-tactile simulation of a vehicle engine, demonstrating the benefits of the multisensory representation of virtual environments.
