We use something similar here (broken arrows pointing to each option, connect an arrow to indicate a vote). What I never understood was what the selling proposition was for the black-box-no-paper-trail machine. You're selling a complex tech product to a very traditional, low-end bureaucracy that wouldn't normally jump on complex tech products. It's probably not about cost of ballots. Even ignoring the up-front cost of the machines, you're going to have to spend quite a bit of money storing and securing the machines, reprogramming them after each cycle, and I wouldn't be surprised if the software is on a subscription basis. i suspect there may be legal requirements for things like absentee and sample ballots that mean you still have to print some paper forms anyway. Accessibility seemed the best argument-- a machine with big buttons and pictures is easier for low vision or mobility users, but there's no reason the machine couldn't be an assistant only-- make your choices, and it prints a regular bubble form ballot you confirm before dropping in the box for counting.
