Designing multimodal virtual environments promises revolutionary advances in interacting with computers in the near future. In this paper, we report the results of an experimental investigation on the possible use of surround-sound systems to support visualization, taking advantage of increased knowledge about how spatial perception and attention work in the human brain. We designed two auditory-visual cross-modal experiments, where noise bursts and light-blobs were presented synchronously, but with spatial offsets. We presented sounds in two ways: using free field sounds and using a stereo speaker set. Participants were asked to localize the direction of sound sources. In the first experiment visual stimuli were displaced vertically relative to the sounds, in the second experiment we used horizontal offsets. We found that, in both experiments, sounds were mislocalized in the direction of the visual stimuli in each condition (ventriloquism effect), but this effect was stronger when visual stimuli were displaced vertically, as compared to horizontally. Moreover we found that the ventriloquism effect is strongest for centrally presented sounds. The analyses revealed a variation between different sound presentation modes. We explain our results from the viewpoint of multimodal interface design. These findings draw attention to the importance of cognitive features of multimodal perception in the design of virtual environment setups and may help to open new ways to more realistic surround based multimodal virtual reality simulations.
