A great deal of research has focused on processing within a single sensory system (e.g., vision, audition, tactile, etc.), the results from which have been used to inform the design of interfaces that best exploit the limits of these individual sensory systems. However, perception is informed by input from multiple sensory systems simultaneously, and the integration of information across senses can lead to greater sensitivity and better overall task performance. We are interested in the underlying mechanisms of multisensory processing, revealed through behavioral, neurophysiological, and neuroimaging approaches, with a goal of identifying ways to provide displays that generate input to two or more sensory systems to direct attention through better cuing, enhance situation awareness, support effective decision making and task performance. Phenomena of interest include multisensory integration, enhancement, facilitation, and interference, perceptual/neural plasticity, and the development and evaluation of models of multisensory interaction.
