Vote-by-Phone: an investigation of a usable and accessible IVR voting system

Danae Holmes, Philip Kortum

Resum


One of the main goals of the Help America Vote Act (HAVA) was to
ensure that voters with disabilities could vote independently. However, the
current state of most voting methods does not allow for independent voting
for everyone. In response to this issue, we tested a remote IVR voting system
developed by Holmes and Kortum (2013), with an added audio speed
adjustment feature and synthetic voice to increase usability and
accessibility, especially for visually impaired voters (Piner, 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.
