Item A Usability and Real World Perspective on Accessible Voting(2012) Piner, Gillian E.; Byrne, Michael D.The HAVA (Help America Vote Act) mandated that all polling places provide privacy and independence to voters. DREs (Direct-Recording Electronic voting systems) have been assumed to be the solution to providing accessible voting, but there is reason to believe extant systems do not adequately serve this goal (Runyan, 2007). Study 1, a mock election, is a first step in addressing the lack of existing data on the usability of accessible voting methods. In comparison with sighted users, blind users took five times longer to vote. Both populations showed similar error rates and types, and reported similarly high satisfaction with the usability of paper ballots. Study 2, a survey, provides the opinions and recommendations of 202 legally blind voters. Data-based recommendations for auditory modes of voting systems include adjustable speed and volume, using male text-to-speech synthesized voices, and allowing for flexible navigation. This research provides a comparison point and guidelines for future studies of accessibility solutions.Item CHILVote: The design and assessment of an accessible audio voting system(2013-09-16) Piner, Gillian E.; Byrne, Michael D.; Kortum, Philip; Lane, David M.; Wallach, Dan S.The Help America Vote Act, passed into law in 2002, mandated that all polling places provide privacy and independence to all voters. Given this, many jurisdictions have been forced into making a choice between providing traditional voting methods (such as paper ballots) and offering newer electronic voting systems. Electronic voting machines have been seen as the solution to many usability and accessibility problems, but very little literature exists to indicate whether this is the case among specific populations such as disabled, elderly, and non-English speaking voters. An audio accessible voting interface for visually disabled voters (CHILVote) was designed using specifications from both the Voluntary Voting System Guidelines and a largescale survey of blind individuals conducted by Piner and Byrne [in proceedings of The Human Factors and Ergonomics Society 55th Annual Meeting, pp. 1686-1690 (2011)]. CHILVote’s interface utilizes the given design guidelines and includes use of a male text-to-speech voice, a flexible navigation structure, adjustable speed and volume, and an optional review section. Relatively low error rates (M=1.7%) and high SUS scores (M=89.5) among blind subjects are consistent with previous findings. Error rates and satisfaction are not significantly different than those of sighted voters using both paper and DRE, and blind voters using a non-electronic interface. CHILVote significantly reduced the time it takes for blind subjects to vote, from 25.2 minutes (VotePAD) to 17.1 minutes (CHILVote). This is an improvement, but still over 2.5 times slower than sighted subjects voting on an identical ballot. The integration of accessibility into mainstream technology often has benefits beyond allowing more of the population access to a system. This research provides a comparison point and guidelines for future studies of accessibility solutions.
