Instead of having to plan the whole motion, the system only has to modulate, guide and correct the natural dynamics. Integration Humans have the capability to receive an enormous amount of information from the world. Visual, auditory, somatosensory, and olfactory cues are all processed simultaneously to provide us with our view of the world. Vision can cause auditory illusions too, such as the McGurk effect. These studies demonstrate that sensory modalities cannot be treated independently.
Sensory integration can simplify the computation necessary for a given task.
Attempting to perform the task using only one modality is sometimes awkward and computationally intensive. Utilizing the complementary nature of separate modalities can result in a reduction of overall computation. We have implemented several mechanisms on Cog that use multimodal integration to aid in increasing performance or developing competencies. For example, O'Reilly and Scassellati implemented a system that stabilized images from a moving camera using vestibular feedback. By integrating different sensory modalities we can exploit the multimodal nature of stimuli to facilitate learning.
