Come to think of it, apparition doesn't make a 'whip' sound. It's
actually like, you whirl around on the spot and then... *CRACK!*

You have memorized the key positions and the music.

Most blind people have some sight and can, in fact, see the
furniture.
The totally blind memorize the position of objects in the room. Part
of the therapy provided to the newly blind is to train them in how to
memorize object locations and to always put things back. It is also
possible for blind people to learn to "see" objects by listening to
reflected sound, much as a bat uses echo location to fly.

How about a regular non-doctor person?

I had a discussion about this just recently. When my brother learned to
play the piano, the teacher had a ruler. If he looked at his hands, she
would whack him on the back of the hand with the ruler. Her students
learned quickly not to look at their hands while playing. She was more
forgiving with the beginning students. If they looked at their hands,
despite her instructions not to, she would simply hold a piece of
cardboard between their eyes and their hands.

My father chimed in at this point. When he learned how to type at
school, all of the keys were removed and replaced with blank keys. It
did no good just to look at the keys, since they were blank. The
students soon learned to "touch type", which is how nearly all
proficient typists work.

If you watch someone tie their shoes, they seldom keep watching once
they've gotten started. The fingers just take over.

This is true for many things in life. For the workstation that a person
normally uses, it isn't necessary to look at the mouse. It's right
where you left it. Once somebody has had a sip of coffee from their
regular cup, and set the cup down on their usual table, they may not
need to look when getting a second sip.

Blind people memorize the furniture and layout in a room. They can move
confidently after learning this information. For an unfamiliar room,
they "probe" with their white cane to find out where things are. You
will often see them circling around trying to find something. I never
know what to do, since some of them resent help because they don't
really learn unless they do it themselves.

ObHintToSightedPeople: Don't ever rearrange the furniture in a room
used by a blind person without telling them first. If you like to
rearrange rooms frequently due to aesthetic reasons, think again.

Goes for dogs that can't see also.

Except that you can't warn them when you've moved things. My sister
moved no furniture in her house for a few years, because her dog Roger
was blind. She did major moving around after he died.

Address your question to Zetsu. It was he who said that vision, memory and
imagination were all "correlated" and one could not be present without the
other. Zetsu promised us that blindness could be cured by fixing the
imagination and the memory.

I don't believe this is true, but you're free to argue with him about it all
you like. This newsgroup appears dedicated to idiotic arguments with no
basis in reality and no relationship whatsoever to established science.

As for you and Zetsu, I'm pretty sure you never met a blind man, much less
cured one.

Re: Playing Piano Blindfolded

If the "blindness" is caused by refractive error, and the memory is
perfect, then the blindness will be instantaneously cured. All
refractive error is functional and therefore lies in the mind, and is
cured by anything that rests the mind such as perfect memory.

In the case that the 'blindness' is caused by an organic disease or
injury, circumstances change. But this does not make the blindness
incurable, in fact, sight may still be restored.

I do not see any controversy in this!

This statement requires the total suspension of disbelief and absolute
ignorance of the processes involved.

Oh, well, since YOU see no controversy, there must BE no controversy.

That's how it IS when you have your own newsgroup to play in.

No, it requires demonstration of the facts.

Actually, I've met someone called 'David Blunket' in person, and he is
a famous MP and blind. He was with a dog.

Amazing how many people you can meet if they don't see you coming.

Re: Playing Piano Blindfolded

I was roaming the streets of Central London and happened to see him.
Well we didn't actually "meet", in the conventional sense of the term.
He was just walking by (aided by a dog) and I passed him closely.

Re: Playing Piano Blindfolded

I am impressed on how people can navigate busy streets, either in London or
in So Cal with a guide dog. They have nerve enough to cross a street where
I fear to tread.

Oh, 2 t's.

We're pretty sure the dog knows more about blindness than you do.

Perhaps it does, but it is difficult to know, since human fluency in
Dog Talk is somewhat poor.
