The study of human multisensory, especially audio-visual perception, has
recently obtained increased attention with the development of virtual reality
systems, teleconferencing, computer games and home theatre systems. An immersive
sound scape can be created by three-dimensional sound applying head-related
transfer functions that “model” human spatial hearing. Already from practice
one realizes that the (spatial) hearing sense is truly multi-modal, applying
also other senses, such as motion (moving the head), vision, tactile sensing
etc. However, due to the technical difficulties and other complexity, serious
efforts to investigate the sensory interactions (especially concerning spatial
hearing) are still lacking. Therefore, a deep understanding of our second
most important sense - hearing - is most incomplete. The author’s research
focuses on the true spatial hearing including interactions between other
sensory modalities, such as audio-visual, audio-motional, audio-visual-motional.
This basic research has strong interdisciplinary connections in various fields
of science and numerous application areas. Novel research paradigms will
be addressed under various objectives.
