Title: Accessibility and Usability Considerations for Remote Electronic UOCAVA Voting

Accessibility and Usability Considerations for
Remote Electronic UOCAVA Voting
  • Sharon Laskowski, PhD
  • National Institute of Standards and Technology
  • http//

TGDC Meeting, July 8-9, 2010
Issues and Recommendations are organized by
  • General accessibility and usability
  • Web browsers
  • Web ballot repositories
  • Online ballot markers and electronic form
  • E-mail
  • Kiosks
  • Telephone-based interfaces
  • Fax machines

Example Recommendations General accessibility
and usability
  • Accessibility and usability best practices and
    guidelines have not been systematically applied
    to design and testing of UOCAVA voting systems
  • Recommendation Where appropriate follow VVSG 2.0
    accessibility and usability requirements and test

Web-based voting
  • The VVSG does not address Web-based voting
    systems or Personal Assistive Technologies (PAT)
  • Use of Javascript and Java applets may lead to
    loss of focus for screen readers
  • Recommendation Follow W3C Web Accessibility
    Initiative WCAG 2.0 and ARIA, Section 508
    guidelines, and best practices for accessibility
    for AJAX (asynchronous JavaScript and XML)
  • Web Content Accessibility Guidelines, Accessible
    Rich Internet Applications

Authentication and CAPTCHAs
  • Some authentication approaches are not compatible
    with accessibility
  • Visual CAPTCHAs
  • Recommendation Follow accessible CAPTCHA design
  • Resizable
  • Adequate contrast to distinguish the CAPTCHA from
    its background
  • Dont use shadows
  • Alternatives, e.g, text readout, phone in

  • For Web-based remote electronic voting, a variety
    of system components must run simultaneously
    operating systems, browsers, voting software,
    PAT, and voting system hardware (for kiosks)
  • Web applications must display properly with all
    commonly-used Web browsers and screen readers
  • Recommendation It is critical to design for and
    test all common configurations for
    interoperability, including testing with PAT by
    testers familiar with using PAT

  • When voters view and/or print documents (such as
    ballots), the documents need to be accessible
  • PDF might not be accessible
  • Recommendations If you must use PDF,
  • Save documents as accessible PDF rather than
  • To support screen legibility for low vision
    voters, check that Adobe Reader reflow feature
    performs correctly
  • If voters need to print for submission, support
    print legibility for low vision voters by
    providing enlarged font documents (not a
    substitute for accessible PDF and/or screen

Telephone-based interfaces
  • Telephone-based interfaces without a screen
    require the ability to hear the prompts and also
    impose a high memory load
  • Recommendations
  • Create requirements based on general best
    practices for interactive voice response systems
  • Require non-auditory alternatives for people with
    hearing loss and non-manual alternatives for
    people severe manual dexterity disabilities
