    Vote-by-Phone: An Investigation of a Usable and Accessible IVR Voting System
    (Journal of Accessibility and Design for All, 2016) Holmes, Danae; Kortum, Philip
    One of the main goals of the Help America Vote Act (HAVA) was to ensure that voters with disabilities could vote privately and independently. However, the current state of most voting methods does not allow for private and independent voting for everyone. In response to this issue, we tested a remote IVR voting system developed by Author 1 and Author 2 (2013), with an added audio speed adjustment feature and synthetic voice to increase usability and accessibility, especially for visually impaired voters (Pinter, 2011). The focus of this research was to examine the viability and usability of the IVR voting system as an accessible voting platform for visually impaired voters. The system was tested by users with and without visual impairments, and usability was measured using the three ISO 9241-11 usability metrics (ISO 9241-11, 1998) of efficiency (time to complete a ballot), effectiveness (accuracy), and satisfaction (subjective usability). Results indicate that the IVR voting system could be a viable voting alternative to other established voting methods, with similar performance among sighted and visually impaired users.ﾠ

    Vote-By-Phone: Usability of an IVR Voting System with Adjustable Audio Speed
    (2013-09-16) Holmes, Danae; Kortum, Philip; Byrne, Michael D.; Lane, David M.
    Currently, there is a lack of usable, remote, and accessible voting technologies that must be addressed. An interactive voice response (IVR) system is one potential solution to this problem, due to its capability of remote use and its audio interface, which is very beneficial for those who are visually impaired. An IVR voting system developed by Holmes and Kortum (2011) was fitted with a synthetic voice and an audio speed adjustment feature for increased accessibility and usability, especially for blind voters (Piner, 2011). This system was tested on the three ISO 9241-11 usability metrics (ISO 9241-11, 1998), efficiency (time to complete a ballot), effectiveness (accuracy), and satisfaction (subjective usability) and compared with the usability of other voting methods in an attempt to determine its viability as a voting method. The usage of the accessibility feature was also examined. Results showed that the IVR voting system is comparable with other voting methods in terms of usability. Results also showed a noticeable portion of non-visually impaired participants utilized the accessibility feature.
