DRM has the potential to impede access for all Canadians, however, one group may be particularly hard hit by widespread DRM use and anti-circumvention legislation. Those with print disabilities (called perceptual disabilities in the Copyright Act) rely on new voice technologies to gain access to works that they are physically unable to view. DRM can be used to limit or eliminate the use of technologies to read text aloud, thereby rendering it inaccessible for a segment of the population. Indeed, for those that think this is a mere fairy tale, one of the better known instances of "read aloud" restrictions involved the Adobe eReader, which restricted the reading aloud function for Alice in Wonderland (the same technology was later at the heart of the Dmitry Sklyarov case).
The Copyright Act contains a specific provision to address access for the print disabled.
