Nonvisual Election Technology Training Curriculum

Purchasing an Accessible Voting Machine 

What do we want in an accessible voting machine?

We want a machine that can be converted for audible voting relatively easily. The machine should be usable by all voters with minimal or no training needed. Integration of all voters is our goal. We do not want a separate blind station. All voters should vote on the same type of machine at a polling location. A machine should be usable by both blind and sighted voters.

What should happen during the ballot review process?

Steve Booth, one of NFB's access technology specialists, helps a blind voter use an accessible voting machine.As blind voters, we should be able to move freely from contest to contest and not be required to listen to all the instructions and text. All the text of each contest must be present and readable if we choose to listen to it. Nonvisual appearance of the ballot does not have to reflect the audio presentation, so the exact appearance of the printed ballot is not important as long as all the information is presented audibly. At the beginning of the ballot, voters should know the total number of contests. The actual contests should be described when they are presented. As each contest is selected, the total number of candidates and the maximum number of candidates to vote for must be announced. As candidates are selected, the number selected should be announced. It should not matter whether a voter decides to cast votes or skips to another contest or just votes for one candidate. Voters must be able to cast their votes at any time. A review function must be available and the voter must have the opportunity to decide whether to listen to the review or cast their vote immediately. During the review process, it should be possible to move freely between contests and to have the chance to change a previous selection. Blind voters should retain the possibility of obtaining the assistance of a sighted reader.

We advocate an active approach rather than a passive one. If we do nothing for more than twenty seconds, an instruction should be given regarding the choice to be made. The system should not move on to another selection or action until an item is completed. If a voter does not take any action for several minutes, the machine should indicate that the voting process is about to terminate with no ballot cast. This protects against someone else voting in place of the present voter.

Other than the visual factor, blind voters have the same capabilities as sighted voters. If a machine is in demonstration mode it should say that it is. Otherwise no special message is needed.

Evaluation Criteria for Voting Machines:

The following criteria are preferred by a cross section of potential blind voters.

Machines should be easy to use by both blind and sighted voters and poll workers. The interface should not require the use of a technical expert, and it should be easy to learn at the polling location. The speech must either be high quality synthetic speech or a high quality digital recording of human speech. Care should be taken by the manufacturer and the voting district to ensure proper pronunciation of candidates' names and information unique to local areas.

Voting machines should be able to display text on the screen, providing touch screen and audio voting at the same time or set to provide visual only or audio voting only. The voter should be able to make these choices on the machine. Large high contrast print and the ability to reverse colors such as white letters on a black background should be selectable.

The volume of the machines must be adjustable by the voter. We also should be able to adjust the speed and pitch of the voice. Recordings should be made so that there are no fluctuations in volume between sections of the voting process.

Keyboards should have reasonably large size keys, preferably larger and with more space between them than a typewriter. High color contrast should be used for voters with low vision. A beep or click should be audible to verify that a key has been pressed. If using the arrow keys, include a selection key. The vote key for casting a ballot should be separate from the other keys or its function should be clearly identified.

For write-in votes, each letter must be selectable by confirming with the select key. There should be a spelling option to review letters entered. The spell function should pronounce the word after it has been spelled. Spaces denote the end and beginning of words. Instructions for selecting letters and completing the write-in selection must be clear and available during the write-in process.

Help should be available throughout the voting process. A separate key should be used to request help, and the help should be contextual, with specific help provided depending on where in the process the voter is when requesting help.

For machines providing printed receipts, a review of the receipt should be read after casting the ballot. It should be similar to what is spoken during the voting process, indicating all votes cast and any contests not voted. No opportunity is given to change selections since a vote has been cast. When an optical scanning system is in use, we have the chance to hear what has been printed and then place our ballots in the box with the other ballots for that polling place.

Instructions must be concise and provide a complete list of the keys and their functions. Voters should be able to move from the instructions to the ballot at any time without having to listen to all the details.

Headphones must be available on site or voters should be able to use their own. Standard walkman style headphones may be used. A standard 1/8th inch stereo mini jack should be provided so that audio is heard in both ears.

We should note that all of the voting machines demonstrated in the National Center on Nonvisual Election Technology have some of the features discussed here, though no single machine has every feature. It is possible to vote independently on these machines by most blind voters. We continue to work with the manufacturers and voting officials on improvements to the machines and the voting process.
