|Usability of Voting Systems|
|chil home > projects >|
Usability by a broad public is particularly important in voting systems. No matter how secure and reliable a voting system is, if that system places demands on the voter such that he or she is unable to vote successfully, or even uncomfortable with doing so, voters will be disenfranchised. Voting is a particularly challenging human factors problem because voting systems must be usable by citizens regardless of age, disability, education, socioeconomic status, history of computer use, literacy level, native language, and the like. A successful system must go beyond simple usability in terms of the voters' ability to accurately cast their vote, but also must produce confidence in the voter that their intention will be accurately recorded and tallied.
Our research in this area has so far consisted primarily of laboratory usability testing on extant voting systems. If new electronic voting systems are to meet standards of usability, what should those standards be? In our view, those standards should be informed by usability data on extant voting systems, such as paper ballots, lever machines, and punch cards. To date, however, such data do not exist (this was surprising to us).
Thus, we are engaged in empirical testing of voters (or potential voters). Two populations have been be used: Rice undergraduates, representing in some sense the "best-case" scenario (highly educated, low rate of disability, high general visual acuity, etc.), and local Houston residents, recruited through newspaper advertisements. These participants have been brought into a laboratory environment and observed interacting with voting systems using primarily objective techniques (i.e., performance measurement of time and accuracy) and subjective measurements such as scaled responses on attributes such as perceived difficulty and trust. Future work may include videotaped "think aloud" protocols.
Once baseline data are available for traditional voting technologies, issues involved with electronic voting systems (called DREs) will be researched. We hope to apply formal usability analysis methods (e.g., GOMS analysis and/or Cognitive Walkthrough) and field testing, including populations with accessibility concerns such as the blind.
