About 15 people in Concord learned how to use voting technology for the visually impaired at FutureInSight, a local non-profit.
The system, called One4All, was first used in the 2016 state primary.
It's tablet-based. There's a keyboard and voice output that reads through the candidates. Voters hit "enter" on a keyboard to pick their candidate.
This year's system has a few small tweaks: the voice output is clearer and a bit faster, for one thing.
