In this session, Dave Gunn and Steve Taylor, RNIB, presented results from benchmarking accessibility tests on the leading global eBook vendors, across all of their platforms (iOS, Android, multifunction devices, eInk devices, Windows 7, Windows 8, Mac OS). Over 30 reading systems were tested on 27 criteria encompassing reading requirements for access by people with low vision, dyslexia and by people who are blind. The session concluded with accessibility statements from Kindle, Kobo and Nook, and a challenge to each of them for improvements to make prior to CSUN 2015.
