>I would like to learn how you experience paintings or sculptures?

I've never been to an art museum where people were allowed to touch anything. There are some that offer descriptive audio recordings for each piece, like the Getty.

I really only experience paintings through other people's commentary. And even then, paintings are not something I actively seek out. But I can't speak for everyone.

Well there are levels of bad sight, I can still see so I just look at art and paint/draw myself (even done some ceramics) but the big museum in town has a sensory installation, so it also adds sounds, smells and you can feel it without setting the alarm going. Those type of installations are generally more VI friendly
