Audio -- Visual Interaction: Multimedia Applications

The entire experience of our environment is obtained by interaction of multiple senses. The most obvious example of such interaction which we encounter in every day life is speech and its comprehension which is affected by vision and hearing. The most significant factor which affects speech comprehensibility during audio-visual interaction is by all means the time synchrony of audio and video notation. The goal of our experiment is to determine the boundaries of sound delay with respect to picture, and vice versa, within which a human being experiences the audio-visual stimuli as synchronous, and to determine to what extent asynchrony of stimuli negatively affects the subjective experience of the observer
