Of our final three designs, this one has the strongest metaphor to a real ballot.
Efficiency:
Learnability:
- Item selection: Because only one item shows up at a time, the user will quickly learn to just click the appropriate name and that the system will move on. Much of the changing between screens is done automatically, minimizing the need for users to learn system navigation.
- Minimal text: Because there is very little text on each screen, the user has very few choices what to do. This makes it easy to quickly determine the right action to take.
Safety:
- With the presentation of the whole ballot on the page, the user has to scroll down, hindering the efficiency.
- The summary page presented to the user requires yet another step of verification.
Learnability:
- Item selection: Because a full ballot is presented to the user, it is pretty intuitive to select the candidates that were voted for.
Safety:
- Right Pane: Seeing immediate feedback on the user's clicks helps the user identify if there were any errors immediately.
- Summary Page: The summary presented at the end allows the user to quickly scan to make sure there were no mistakes.
- One-click Process: Because the system advances on any click, the user doesn’t have a chance to verify that they selected the correct option, reducing the safety.
- Large Buttons: The buttons are all large, so the likelihood of accidentally clicking the wrong button will be smaller. Users will also see the button depress when clicked, so they will get that feedback about which element has been selected. These together improve the safety.
- Forward/Back Buttons: If the user makes a mistake, she can chose the back button to correct it. Error correction improves safety. The forward buttons let her navigate back to her current position without reentering information – which would increase the likelihood of making another error.
- Status Ballot Count Bar: The user can keep track of how far she is. This allows tracking of how far in the process she is, and in case a ballot got missed or double-submitted, this mechanism will help her catch that error.
