According to U.S. Federal Law, all Americans must have equal opportunity to participate in the voting process. That means everyone, including the blind and visually impaired, has the right to vote independently and privately and is entitled to accessible polling places with voting machines appropriate to their needs.
Voting systems must be accessible for individuals with disabilities, including non-visual accessibility for the blind and visually impaired, in a manner that provides the same opportunity for access and participation as for other voters-including privacy and independence.
Every polling place should have at least one direct responding electronic (DRE) voting system equipped for individuals with disabilities. This is usually a touchscreen voting machine that is capable of operating in audio mode for individuals with visual disabilities.
