Designing for one particular disability (impaired vision) isn't never
enough, and unfortunately, it can be mutually exclusive to some degree.
If you imagine something designed specifically for the visually impaired
(e.g. everything is audio), then hearing impaired are locked out.
Similarly, designs specifically addressing physical impairments can
drive everyone else nuts.
