The proportion of Web access is increasing for mobile devices but declining for the desktop computer. Accordingly, designers of survey instruments should consider making their Web surveys conform to Section 508 guidelines not only for the desktop, but also for mobile devices. Persons with low or no vision navigate on a desktop computer by tab, enterand arrow keys with a screen-reader speaking labels, instructions, and response options. Mobile device keyboards cannot be used to navigate this way through any Web survey instrument. Instead, persons using mobile devices use gestures to navigate. When a screen-reader user moves their finger on the screen, a correctly programmed interface will speak the instruction or question text, button labels, and status of a radio button or checkbox response option when touched. The user will then hear this feedback and can provide a response. This presentation will discuss guidelines for creating an accessible mobile Web survey using Apple Siri and Google Talkback.
