Visual Sense is dominant

Vision is our most dominant sense – taking up 50% of our brain’s resources. Data visualization expert David McCandless explains:
“This is your senses, pouring into your senses every second. Your sense of sight is the fastest. It has the same bandwidth as a computer network. Then you have touch, which is about the speed of a USB key. And then you have hearing and smell, which has the throughput of a hard disk. And then you have poor old taste, which is like barely the throughput of a pocket calculator. And that little square in the corner, a naught 0.7 percent, that’s the amount we’re actually aware of.”
