On February 9, the Fourth Circuit issued an opinion in National Federation for the Blind v Lamone, 14-2001. The Fourth Circuit agrees with the U.S. District Court, which in 2014 said Maryland must permit blind voters to mark absentee ballots at home with help from an “online ballot marking tool.” Such voters may print a ballot from the internet, and then use the device to mark it. The decision is based on the federal Americans with Disabilities Act.

See this story, which explains how the tool works. The story is from 2014, when the U.S. District Court opinion came out. Thanks to Rick Hasen for the link to the decision.
