Sounds like what most places museums do already offer though some will even do more let you touch thing. I was able to touch stuff at a few history places like the liberty bell, the library of congress, the statue of liberty

So it's just the Aira app?

Ok?

For really broad accessibility, I recommend the German Historical Museum (Deutsches Historisches Museum) in Berlin. (Currently undergoing massive renovate, but the Pei building is still open with great exhibits including art as well as history)

- most signage/documentation in German, English, and simplified German (which is becoming the norm in state museums)

- video presentations to complement the exhibit, in German sign language

- tactile strips on the floor, and tactile squares in front of the exhibits, to guide those who are visually impaired around the exhibits

- tactile displays people are encouraged to touch

- Braille informational signs

- audio guides

Germany has a huge number of really good quality museums and galleries, but also does a very good job of presenting the contents in ways that almost everyone can enjoy. (Private places, not so much, like the miserable experience at the spy museum in Berlin....)

Nobody yells at me either when I put my nose almost to the text, or stand a few centimetres from a painting, like they are apt to do in American or Canadian museums. There is a strong mentality of 'everyone should be able to enjoy art in the best way possible for them'.
