My intuition leads me to answer something like "Yes, probably, after
some learning process".

I am not sure the ability to identify a picture by touching it has
something to do with the fact of borning blind or becoming blind later.
In other words, I don't know whether a person that saw a microphone will
be able to associate the dots she touches with the image of the
microphone she may have kept in her mind.
But that's a totally different topic...

Thanks anyway for your explanations, Herman, and thanks to all of you
for your replies.

Sébastien.
