With Shabbos ending well past 9 p.m. in the summer there’s a long afternoon to fill — and as the People of the Book many of us are happy to have the extra time to curl up on the couch with some good reading material. But what about the visually impaired? During the week they can now read or listen to just about anything off a computer with the help of special refreshable Braille displays (a sort of keyboard connected to the computer with hundreds of tiny pins that rise and fall as they convert text from the screen into Braille letters) or audio programs. On Shabbos however the computers and those books and tapes are shut off.
