I did enclose with <if I ran the world> :-)
This all started me thinking. There are approximately 1.2million
nerves in the optic nerve. I can't easily find bit rates for human
But lets assume an upper bound of 100bits/s (we certainly can't
perceive monitor refresh rates above about 75Hz). Then if
we assume normal stereo scenes I guess that the information
content for two eyes is only 25% more than for one eye.
So it's an interesting world that leads engineers to build systems
with 10-64Gb/s in order to deliver to the human visual system
that can only really deal with of the order of 150Mb/s.
