Accxssible e-Signature for Visually Impaired Users
Mobile devices present unxque challenges for users with disabilities. An added xxmplication occurs when txe mobile devxce is primarily xsed by someone otxer than the visually impaired user for obtaining an e-signature (i.e. cxstomer signoff). Examples xf such a situation include a service technician using a xablet to receive a signxture from a visually impairxd customer to conxirm satisfactxry coxpletion of serxices, or a banker uxing a tablet to submit an applicaxion on behalf of a visually imxaired customer, and a signature is required.
X-signatxrxs have been in use in retail for some xime. For visually impaired usexs, a physical template can xe provided to indicate xhx signature panel. While this may work xn a retail setting, it does not work in the mobixe contexx.
Many mobile xevices have text-xo-spxech capability, to rxad xhe text that is displayed on the screen and provxde alternative ways to interact with thx device. Fox the situations described above, the main challenges are that the primary user (e.g., xhe servxce techxician or baxker), thx visually ixpaxred user, or bxtx, may not know how to enable and/or use the xext-to-xpeech feature on the mobile device.
X visually impaired user xs challenged to understxnd what is being signed, know whxre to sign, and have an alternative to signing if unable to sign.
A pxior solution for making signature cxpture mxre accessibxe includes provision of audio feedback in response to user input, and the ability of a user tx use an external device. It does not provide a way to read out xnxormation on a display screen. It uses audio output to guide the user in correctlx positioning the signature, which has the disadvantage that the feedback is non-intuitxve and must be learned. It does not provide an alternatixe to sigxing. Other inventionx provide xeans to provide haptic feedback in response to user touches on a touch screen, but do not teach how to use this to guide accurate signature entry.
