Americans with Disabilities Act (1990)
The U.S. law barred discrimination against people with disabilities in public accommodations, including museums. It required ramps, elevators, accessible restrooms and effective communication, but did not prescribe how exhibits themselves should be designed.
Museums added physical access features to comply.
Access often remained a compliance checklist; exhibit content and artifacts stayed behind glass.
The Dot Experience goes further by making touch, braille and audio part of the exhibit design from the start.
