CAL has been highly promoted and its values and advantages
should be available to all, not just to a certain group
of people or even the majority. It is important to plan,
design and manage a user friendly and inclusive public
CAL learning environment. It is often suggested that more
personal learning facilities should be provided. However,
personal CAL facilities are expensive and still not commonly
available for children with visual impairment,
though there has been a big leap in the development of
interactive technology over the past two decades. Nevertheless,
the development of CAL facilities for children with
visual impairment is lagging far behind due to the practical
difficulties of development and the low market value. The
situation is compounded because the hardware and software
is constantly changing and children with visual
impairment need to put continual effort into familiarizing
themselves with such changes.
