Abstract

We investigate the influence of four different audio representations on visually induced self-motion (vection). Our study followed the hypothesis, that the feeling of visually induced vection can be increased by audio sources while lowering negative feelings such as visually induced motion sickness. The test participants wore a head-mounted display (HMD) with headphones and were moved forward linearly in four different virtual scenes to create visually induced vection. One of the four scenes had no auditive stimulus, the other three had mono, stereo or spatial auditive stimuli. The last two were set up for the directional localization of the same sounds from the same places, while the mono source has been homogeneous wind noise with raised and lowered frequency according to the virtual speed. The scenes with stereo and spatial audio did not lead to the expected significant increase of linear vection in contrast to the reference scene without visual stimuli and also not among each other. However, the mono wind scene significantly increased vection to the visual reference scene.
