thumb|250px|Detail view of the optophone The optophone is a device, used by people who are blind, that scans text and generates time-varying chords of tones to identify letters. It is one of the earliest known applications of sonification. Dr. Edmund Fournier d'Albe of Birmingham University invented the optophone in 1913, which used selenium photosensors to detect black print and convert it into an audible output which could be interpreted by a blind person. The Glasgow company, Barr and Stroud, participated in improving the resolution and usability of the instrument.

Vinux was a Linux distribution which was specially designed for blind and partially sighted users. Specifically it was a remastered version of the Ubuntu distribution and provided users with two screen readers, two full-screen magnifiers, global font-size and colour changing facilities. The system also supported USB Braille displays.

area of research

BrainPort is a technology whereby sensory information can be sent to one's brain through an electrode array which sits atop the tongue. It was initially developed by Paul Bach-y-Rita as an aid to people's sense of balance, particularly of stroke victims. Bach-y-Rita founded Wicab in 1998.
