Access
Obstacles
Many obstacles
are perceived as access obstacles. The categories below describe technical access
obstacles. Economic andPolicy obstacles are a separate
issue.
- Platform dependance
is lessening as a problem as the World Wide Web provides platform independant
resources. Still, browser wars and Java controversies delay true platform
independance.
- Resource Access is
slow. There is some critical time limit measured in seconds after which
a resource becomes useless.
- Providing a powerful
source of information often includes providing a complex and non-intuitive
interface.
- Information ideally
should flow from one resource to another. Immature or unadopted standards
for terminology, data exchange, or process interaction create linkage problems
that often require human intervention to manually transfer information from
one resource to another.
- If the resources or
their linkage do not match the work flow of a user solving a problem, valuable
seconds, or even minutes, may make the resource unuseable despite any improvements
in performance of the software.
