@ArchaeoBasti i remember going to the natural history museum in 2015 to try their oculus rift experience (nearly 10 years ago!). it had to be a theatre-like experience to scale.
having visitors bring their own kit adjusted to their eyesight and able to be used while walking will make a difference. however, the price will have to come down a lot first and it's a chicken-and-egg situation as to when adoption will happen.
