Alan: It can be claimed that the entire nervous system is designed around
the
visual sense.
This made me jump. In some ways I have a lot of sympathy - putting
imagination (if visual imagination) at the centre of sensory processing of
the world.
But it's almost certainly wrong/ inadequate - and not something a roboticist
should say.
http://en.wikipedia.org/wiki/Two-streams_hypothesis
The probability - personally I would say almost certainty - is that
perception is inseparable from action. "No representation without action"
(or somesuch). The system can't look at something without thinking what
it's going to do about it.
Embodied cognitive science, it seems to me, stresses that embodied
perception and thought are necessary to *understand* what we see and think
about - e.g. the mirroring of others' actions via mirror neurons. We
*identify* with the objects and object actions we see and think about.
But, on looking at Wiki, I see that there is also "animate vision" (vs "pure
vision"), pace Clark,
"Animate vision, by contrast, sees vision as the means by which real-time
action can commence."
http://en.wikipedia.org/wiki/Embodied_cognitive_science
We automatically *re-act* to what we see and think about - *take a position*
as to what we're going to do about it.
If anyone knows more about this, I'd be interested - because my impression
is that "animate vision" (I'd prefer another term) hasn't had much of a
press.
But one consequence of all this is that "virtual AGI" should now be a dead
project - it's an absolute waste of time, (other than for simulating robotic
action experimentally).
P.S. Evolutionarily of course, vision is secondary. Life begins with much
simpler sensations, external and internal. Developing a rudimentary sense of
one's body in an immediate space precedes more detailed observations of the
nature of that space and body. Vision presumably is necessary when you can
undertake longer distance action.
