tive integration of accessibility will
account for accessibility concerns
throughout the development life cycle, at minimal cost. As with physical
architecture, where the cost of accessibility in new designs is small compared to the cost of retrofitting after
the fact, incorporating accessibility
features early in design may add only
2% to 3% to the cost and time of development. 14 Products and services
accessible from the outset provide all
users immediate access, while leaving
accessibility features for “version 2.0”
effectively discriminates against users
who need assistive features today.
Embracing accessibility might
also help technology providers avoid
exposure to potential liability under
laws that do not necessarily focus on
accessibility. Websites that provide
special online-only pricing for goods
or services might be engaging in illegal pricing discrimination if their
designs are either inaccessible6 or do
not consistently provide accommodations required by law. 4 The resulting
violations could involve multiple laws,
some possibly risking more serious
penalties than those associated with
the disability rights laws described
here. Likewise, recruiting websites or
employers requiring online applications without providing equal access
for people with disabilities could be
engaging in illegal forms of employment discrimination. 5
Accessibility is an issue outside the
U.S. as well. Just as in the U.S., laws
in other countries typically start by
requiring accessible government information. Australia, Canada, France,
Spain, and others have laws relating
to the accessibility of government information technology. The U.K., with
its Equality Act of 2010, was one of the
first countries outside the U.S. to require accessibility in the greater community for companies and organizations. For additional discussion of IT
accessibility laws outside of the U.S.,
see ACM interactions magazine’s forum on interacting with public policy
and the W3C’s Web Accessibility Initiative on government policy.
Weighing the trade-offs in policy re-
quires consideration of costs and ben-
efits from the perspectives of multiple
to avoid undesired (and unintended)
consequences, ACM members can
help make accessibility much less

interested parties, including individu-
als in need of accessible technology,
educational institutions, and busi-
nesses and organizations that provide
information and services. Due to the
important effect that laws and regula-
tions have on interaction designers,
software engineers, Web developers,
and other IT professionals, it is impor-
tant to not only understand how the
laws affect developers but also to be
involved in the policy-making process.
Computing professionals inter-
ested in promoting accessibility can
engage with lawmakers, advocacy
groups, and industry partners to share
their understanding of accessibility
and encourage development of appro-
priate technology and policy. Com-
ments on proposed legislation and
regulation could raise concern as to
definitions or implementation chal-
lenges, identify potential unintended
consequences, suggest alternative ap-
proaches that might encourage acces-
sibility, and educate legislators and
rulemakers who might not be well
versed in the technical details. Par-
ticipation in bodies like the W3C can
help develop widely used approaches
for addressing accessibility concerns.
ACM has been involved since 1992
through its ACM U.S. Public Policy
Council (USACM) and accessibility
subcommittee. USACM actions on ac-
cessibility include a statement advo-
cating Web-accessibility principles
and comments on various policy pro-
posals related to the ADA, Section 508,
and accessibility of electronic health
records. Membership in USACM is
open to all interested ACM members
in the U.S. ACM seeks to educate poli-
cymakers and the public, as well as
the computer science community, on
science and technology. ACM engages
through USACM for technology policy
and the Education Policy Committee
for educational matters. ACM special
interest groups, including SIGAC-
CESS, SIGCHI, and SIGWEB, often
engage in accessibility issues; confer-
ences, including ASSETS and CHI,
showcase accessibility research.
Computing professionals have
much to contribute to the discussion.
By suggesting opportunities for bet-
ter design, outlining paths to afford-
able accessibility, and constructively
critiquing policy proposals aiming
