The popular
image of a blind person is of someone who is young, totally blind,
reads Braille, musical, happy, loves animals and has bionic hearing.
However reality is somewhat different - the visually impaired population
is far from homogeneous and has very varied needs and aspirations.
This report describes some of the scientific and technological research
which has been done to alleviate their problems, with special emphasis
on projects in which the RNIB Scientific Research Unit has been
involved.
Technological
developments have helped visually impaired people, but they have
also resulted in extra problems. For instance the increasing use
of terminals with visual displays, such as cash dispensers and mobile
phones, mean that access to services may be restricted for those
who cannot read the visual display.
The general
approach has been to encourage designers to incorporate features
in the standard product which will help people with disabilities.
If this is insufficient, then to incorporate a standard method of
connecting the user's own device which has an appropriate user interface.
But if neither of these approaches provides a satisfactory solution,
then special equipment will be needed.
Inclusive design
is not just adding an extra feature to a product to meet the perceived
needs of a disabled user. It is a process, like quality, which has
to be considered at every stage in developing a new product or service.
This requires companies to promote a culture of inclusion within
their organisation. It also requires detailed technical guidelines
on the design features required by the various groups of disabled
users.
