What are accessibility
standards who do they apply to?
The internet’s “Web Accessibility Standards” are
certain protocols and guidelines set by the W3C(.org), to
assist web designers and developers of internet sites and other hypermedia,
as well as the software makers {eg web browsers, Html editors, etc}. This
makes way for the ability for across-the-board accessabilty standards,
as well as keeping all the internets information as accessible to the deaf
and blind as much as possible. Thus, disabled users will not be discriminated
against by the lack of good web coding practices.
“…Rehabilitation Act to require Federal agencies to make their
electronic and information technology accessible to people with disabilities.
Inaccessible technology interferes with an individual's ability to obtain and
use information quickly and easily. Section 508 was enacted to eliminate barriers
in information technology, to make available new opportunities for people with
disabilities…”…from http://www.section508.gov/
Thus, everyone on using the internet is affected by accessibility issues,
and all individuals and companies making related product and media need
to adhere to these rules.
Do you think accessibility standards are or are not important
and why?
“…Section 508 will open many more doors to information
for people with disabilities...”
Accessibility standards are essential whether recreation, buisness, schooling,
finance, or personal well-being. This is not only due to the capabilities
ensured the standards for disabled people to function on the internet,
and with the broad range of digital media and ability to perform functions
of independence, but also as a standard of professional practice for
web designers as they create the roads of transition and interfaces of
information, throughout the internet. If these pillars of creation do
not allow for such consideration and practice for their clients, and
client of clients {and so on}, the integrity of the internet will be
lost; and one of the most important and influential tools in humanity.
“It also has legal implications … Web standards and accessibility
can help your site stay on the right side of these laws.”
Give an example of Specific user groups with particular accessibility
requirements?
The groups that coagulate specific user groups utilizing advanced accessibility,
closely linked to the humans senses, are:
- The blind. This user group would be most likely to use banking, and
communication functions on the internet. The programs used would be
a ‘reading’ software to announce and read out what
is on the webpage, and also speech recognition software to navigate
and type – adaptations for these software programs (and them
using them,) would be needed.
- The deaf. This user group would most likely use banking, recreation,
and communication and research faculties on the internet. Audio sites,
as well as sites playing music cannot assume their listeners aren’t
deaf and would need to make those amendments (such as a visual sign
of music playing, or an oscilloscope, etc)
- The physically disabled. This user group would most likey be accessing
all areas of the internet, but consideration would be needed as they
may be utilizing anything such as: the tabbing system, virtual keyboard,
speech recognition, narrator, web-page-reader, etc
What is an example of a General legislated accessibility standard
and requirements?
DISABILITY DISCRIMINATION ACT 1992
- SECT 45
Special measures
This Part does not render it unlawful to do an act that is
reasonably intended to:
(a) ensure that persons who have a disability have equal opportunities
with other persons in circumstances in relation to which a provision
is made by this Act; or
(b) afford persons who have a disability or a particular disability,
goods or access to facilities, services or opportunities to meet their
special needs in relation to:
(i) employment, education, accommodation, clubs or sport; and
(ii) the provision of goods, services, facilities or land; or
(iii) the making available of facilities; or
(iv) the administration of Commonwealth laws and programs; or
(v) their capacity to live independently; or
(c) afford persons who have a disability or a particular disability,
grants, benefits or programs, whether direct or indirect, to meet their
special needs in relation to:
(i) employment, education, accommodation, clubs or sport; or
(ii) the provision of goods, services, facilities or land; or
(iii) the making available of facilities; or
(iv) the administration of Commonwealth laws and programs; or
(v) their capacity to live independently.
Include a checklist of the WCAG 2.0 guidelines and whether
you’re your front page adheres to the them?
Guideline
1.4 : Make it easy to distinguish foreground information
from its background |
|
Success Criterion |
L2 |
1.4.1Text or diagrams,
and their background, have a luminosity
contrast ratio of at least 5:1. [How
to meet 1.4.1] |
1.4.2A mechanism is
available to turn off background audio that plays automatically,
without requiring the user to turn off all audio. [How
to meet 1.4.2] |
L3 |
1.4.3Text or diagrams,
and their background, have a luminosity
contrast ratio of at least 10:1. [How
to meet 1.4.3] |
1.4.4Audio content does
not contain background sounds, background sounds can be turned
off, or background sounds are at least 20 decibels lower than
the foreground audio content, with the exception of occasional
sound effects. [How
to meet 1.4.4]
Note: A 20 decibel difference in sound level
is roughly four times (4x) quieter or louder. Background
sound that meets this requirement will be approximately four
times (4x) quieter than the foreground audio content. |
Guideline
2.2 : Allow users to control time limits on their reading
or interaction |
|
Success Criterion |
L1 |
2.2.1For each time-out
that is a function of the content, at least one of the following
is true: [How
to meet 2.2.1]
- the user is allowed to deactivate the time-out;
or
- the user is allowed to adjust the time-out
over a wide range that is at least ten times the length
of the default setting; or
- the user is warned before time expires
and given at least 20 seconds to extend the time-out with
a simple action (for example, "hit any key"),
and the user is allowed to extend the timeout at least
ten times; or
- the time-out is an important part of a
real-time event (for example, an auction), and no alternative
to the time-out is possible; or
- the time-out is part of an activity
where timing is essential (for example, competitive
gaming or time-based testing) and time limits can not
be extended further without invalidating the activity.
