The priority source of information for the brain is vision Although multisensory perception is better than single-point-of-entry one, vision is still the most efficient point of all. A simple experiment proves this. If you change the color of the wine in the glass, even the best sommelier will be confused. He will simply ignore the taste and aroma based on what he sees.
Sight dominates all the other senses. The processing of visual signals in the brain is extremely complex: if there are gaps in the visual field, the brain attempts to fill them on its own.
Even now, while reading, you have a highly complex mental activity going on, with our brain perceiving each letter as a separate visual signal.
