One of the most striking aspect of electoral ergonomics pertains to the nature and design of the ballot paper. Is it an actual paper or an electronic one? Is it a single piece of paper or several? What is indicated on the ballot? Are there names of candidates or parties, images or not, how about colours? Are voters expected to punch holes on the ballot, tick, circle, cross, or even choose a pre-printed ballot without altering it or writing on it in any way? Do they return them open or in an envelope? All these details deeply affect the ergonomics of elections, the experience of voters, the time they spend casting their vote and their satisfaction.
