However, children with visual impairment often need to
spend more time and take special care in learning because
learning materials only tend to be provided in visual format.
Yet despite the drawbacks, extending access to personal
CAL facilities would still be a positive move in the
right direction. If more subsidies were available to provide
personal CAL facilities for children with visual impairment,
they would not need to spend time accessing public
facilities away from their home environment. In the
meantime, public CAL facilities are still necessary. It is not
helpful to isolate children with visual impairment from
other learners, as they need to be able to share their
knowledge and experience. It is particularly important for
young children to learn under guidance and sharing. As
mentioned above, CAL facilities for the visually impaired
are often very expensive due to their special design features
and the small volume of production. Some of them are used
infrequently, are large in size and may be of lower quality.
Thus, public CAL facilities can utilize resources effectively
and can be updated more frequently.
