Interactions and Integrations of Multiple Sensory Channels in Human Brain

This paper describes a couple of new principles with regard to interactions and integrations of multiple sensory channels in the human brain. First, as opposed to the general belief that the perception of shape and that of color are relatively independent of motion processing, human visual system integrates shape and color signals along perceived motion trajectory in order to improve visibility of shape and color of moving objects. Second, when the human sensory system binds the outputs of different sensory channels, (including audio-visual signals) based on their temporal synchrony, it uses only sparse salient features rather than using the time courses of full sensory signals. We believe these principles are potentially useful for development of effective audiovisual processing and presentation devices
