Abstract

In our natural environment, we simultaneously receive information through various sensory modalities. The properties of these stimuli are coupled by physical laws, so that, e.g., auditory and visual stimuli caused by the same even have a fixed temporal relation when reaching the observer. In speech, for example, visible lip movements and audible utterances occur in close synchrony which contributes to the improvement of speech intelligibility under adverse acoustic conditions. Research into multi- sensory perception is currently being performed in a great variety of experimental contexts. This paper attempts to give an overview of the typical research areas dealing with audio-visual interaction and integration, bridging the range from cognitive psychology to applied research for multimedia applications. Issues of interest are the sensitivity to asynchrony between audio and video signals, the interaction between audio-visual stimuli with discrepant spatial and temporal rate information, crossmodal effects in attention, audio-visual interactions in speech perception and the combined perceived quality of audio-visual stimuli.
