Special interface unit for blind telephone switchboard operators, made by the RNIB, NRDC and Imperial College, London, England, 1977.
In 1977, a project was begun at Imperial College, in partnership with the Royal National Institute for the Blind, to develop an interface unit that would allow blind telephone operators to use modern telephone exchanges. Previously, blind operators had relied on touch, with the standard flashing lights of a telephone exchange unit being replaced with pins that would protrude to indicate different functions. However, this was proving inadequate for the levels of information being made available by telephone exchanges. A new interface unit was designed by Graeme Wood, a post-graduate student at Imperial College, which instead gave basic audio instructions to blind operators. This set was the pioneer equipment that was installed at the Royal National Institute for the Blind.
