Current development is focusing on visual and mobility impairments. There are both software and hardware based solutions available. There are also both console and graphical solutions available, however, the graphical solutions are limited at this time.
The biggest advantage of the hardware speech solutions is that speech is available before the operating system loads, which even makes it possible for people with a visual impairment to install the operating system. Hardware solutions include speech synthesizers, braille terminals, braille printers, sip and puff systems, and eye gaze pointing devices. These devices are usually very expensive and it is difficult to find drivers for them. Drivers are being written (mostly for speech synthesizers) for Linux but they need to be tested and integrated by the community into "upstream" software projects before becoming part of Fedora.
