Vibrotactile enhancement of auditory-induced self-motion and spatial presence

Watermark, 2012

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 ...

Distortion of auditory space during visually induced self-motion in depth

Frontiers in psychology, 2014

Perception of self-motion is based on the integration of multiple sensory inputs, in particular from the vestibular and visual systems. Our previous study demonstrated that vestibular linear acceleration information distorted auditory space perception (Teramoto et al., 2012). However, it is unclear whether this phenomenon is contingent on vestibular signals or whether it can be caused by inputs from other sensory modalities involved in self-motion perception. Here, we investigated whether visual linear self-motion information can also alter auditory space perception. Large-field visual motion was presented to induce self-motion perception with constant accelerations (Experiment 1) and a constant velocity (Experiment 2) either in a forward or backward direction. During participants' experience of self-motion, a short noise burst was delivered from one of the loudspeakers aligned parallel to the motion direction along a wall to the left of the listener. Participants indicated from...
