[Blindmath] Perspective and the blind

[Michael Whapples]

Interesting to read your opinion.

"I assume that most blind people could learn to do this if they did it 
every day for 50 years."
The question of understanding or the ability to copy. May be copy is not 
quite the word I mean, but hopefully my meaning can be got. If you 
encounter something enough you will observe things, but it does not mean 
you understand or could explain why what you observe is the way it is. 
So is he just observant and knows how to represent perspective or does 
he understand it?

At the other end of the scale, one could do much calculation of 
perspective and how large something at a certain distance should appear. 
Let me use an example: The moon and the sun appear to be about the same 
size when observed from the earth, this allows a solar eclipse to 
happen. If you know the distance from the earth to the moon, the 
distance from the earth to the sun and the radius of the moon, can you 
calculate the radius of the sun?

"Watching this blind artist he seems to be a happy person who enjoys life."
May be really the most important thing, to enjoy life. If you enjoy what 
you do, then does it really matter how you achieve it.

First, his art is not overwhelming--it's in what is sometimes called primitive or folk art style.  Second, there is no evidence that he can read and write.  Also, in the videos he was always helped by a sighted guide rather than using a cane.

My guess, although I've not read this anywhere, is that sighted people produced tactile drawings for him when he was quite small so he became familiar with them from a very early age.  He supposedly started painting by age 8. He paints by using his fingers to fill in outlined areas with dabs of viscous oil paint so his paintings are quite textural.  I read that he only uses 5 colors and lets each one dry before using another. It looks to me as though he uses one hand to feel for the embossed borders and the other hand to paint.  I assume that most blind people could learn to do this if they did it every day for 50 years.

He might have picked up this information from tactile drawings.  The main reason seems to be that he knows that to a sighted person lines that are receding appear to be angled. Again, I would guess that he could have picked this up from tactile drawings made by sighted people.
