In 2011, I followed a group of blind folks touring the Picasso exhibition with the help of visual aids.

The maker of these aids, Seattle artist Hjylimar Hinn, has now made 20 "braille docents," as he calls them, for King Tut at Pacific Science Center. They're braille "maps, if you will, of the artifacts" that are then described verbally in the galleries, Hinn says. Visitors who don't see can instead run their fingers over the "maps," gaining a different sort of understanding.
