We had a few different ideas for changing up the structure of the polling place:
Brian suggested that we create two lines, very similar to the various lines you see when you go through airport security. Could we make it "ok" for anyone who needs a little extra time to select the "want more time" line? Of course we'd need to make sure that there were enough polling booths at each group so that the folks who needed more time didn't end up waiting too long to cast their ballot.
What if we could have signposts at different points throughout the line that explained different parts of the voting process, as Nathan has outlined here? The signs could explain the materials you need to check in, the different languages a voter can select for his or her ballot, or even how to signal to a poll worker that you need help, without getting out of line?
Focusing more specifically on privacy, Yusuke also suggested a new format for the polling place (top right) where all of the voting booths were behind a special curtain. Voters would queue up behind the curtain, and when you got to the front of the line, you'd get to choose the type of accessible voting options you needed. This would enable any voter to request certain voting access with a greater degree of privacy and security than going straight up to a poll worker and asking for help in front of everyone.
