Overview
TPG assumes that IT vendors will develop and/or incorporate assistive technologies for one or more of the
following reasons:
 To comply with existing regulations in markets where these regulations exist
 To comply with anticipated regulations in markets where these regulations are expected
 To exploit a market demand for these features, regardless of regulations
 To generate goodwill and be perceived as good community citizens.
Gov. (Federal/State) vendors seek to assess the market opportunity for IT accessibility solutions, based on
an analysis of:
 The current and future regulatory environment
 Current and future buying behavior in the public and private sectors
 Current and future competitive strategies and tactics.
Federal Agencies are on record and have publicly committed to Section 508:
 SSA, DoD, DoED, VA, State Department, etc..
 Example: Department of Homeland Security


Access to the Web and IT for DHS employees and US citizens (http://www.DHS.gov/DHSpublic/accessibility.jsp)
Enforcing 508 compliance through RFP’s, including the SPIRIT initiative
This presentation serves as a foundation for IT vendors to make decisions on where to focus resources in
the development and deployment of accessible products and solutions.

The Business & Technology Opportunity
Observations
 Federal Government is the single largest employer of people with disabilities
 Federal laws including Section 508 & Section 255 mandate technology be accessible
 Federal agencies are enforcing, requiring major shift in vendor product development and positioning
Result = “Accessibility Gap”
 Technological advances in the field of accessibility lag behind greater advances in mainstream information
technology
 Disability demographics
 Estimated 54+ million Americans with disabilities
 Growing percentage using computers & Web resources
 Combined with aging population of computer users demanding more services
Net Effect
 People with disabilities & senior citizens lack mainstream technology inclusion.
 Section 508 is a new and fast growing “market maker”

Issues

Accessibility old/new dilemma

Limited in-house expertise at EVERY level (management, development, sales)

Industry standards are “thin” and infantile

Formulas for formal evaluation methods to calculate accessibility measurements do not exist

Understanding IT Accessibility
Electronic & Information Technology (E&IT) must be accessible to a variety of users with
disabilities without relying on a single sense or ability.
Examples


Systems that require “mouse”-only input are not accessible to blind or some with physical disabilities
Web sites containing images, media, and applications must be accessible to all users with disabilities
Key Goal: Whole systems of technology that are inherently accessible.

Example: Network operating systems with built in screen-readers, visual system alarms, on-screen keyboards
Accessibility may be achieved by enhancing the system’s ability to interact, co-exist, or be
compatible with adaptive and assistive technology.

Example: Web-based kiosks that are wheel-chair accessible
There are alternative ways to accomplish the same objective



Do not strictly focus on web/software accessibility techniques, standards, and “doing it this way or that way”
Give primary focus to user needs, user requirements, user testing process
This results in sites, applications, and services that are “coded” accessible and usable
Key = attitude and user inclusion

Development Strategy
Most Common Software/Web Accessibility Issues

Content (structure/presentation, images, multimedia)

User Interface (limited user preferences)

Functionality is incompatible with Assistive Technologies

Lack of implementing Operating System/Application Library accessibility functions (MSAA/Java)

Assistive technologies are behind technology curve

Lack of documentation, robust Help systems

Usability
Remember: Design usable and accessible software that accommodate people with disabilities by:

Implementing corporate processes, policies and standards that support accessible design.

Positioning accessibility as a core competency.

Educating internal resources.
Key Alerts:

Current accessibility validation tools are not effective

Iterative user testing is the best way to ensure accessible user experience

Usability Evaluation Methods
4 Basic Evaluation Methods

Automatic (software tools)

Formal (exact models/formulas to calculate measures)

Informal (experienced evaluators conducting usability inspections)

Empirical (usability testing involving users)
Best Practice Recommendation

Combine informal inspections & empirical testing
Usability inspections result in immediate, accurate, and long term benefits to
the UI
Empirical studies ensure Accessible User Experience (AUE)

Usability Inspections
2 Simple Objectives

Find usability problems within existing UI design

Make recommendations for improving & enhancing
Usability Problems to Review

Ease of Use
-Error Seriousness

Efficiency
-UI “pleasantness”

Error Frequency
Resulting Recommendation Report

Identify problems and suggest redesign solutions

Prioritize list of usability problems based on rate of occurrence, severity level, &
market/user impact

Where possible, estimate implementation cost & cost-benefit analysis

Usability Inspection Methods
Heuristic evaluations (expert reviews)
Guideline & Standards reviews (conformance review)
Walkthroughs (user/developer scenarios)
Consistency (family of products review)
Formal usability inspections (moderated & focused inspection)
Feature inspections (function, utility review)

Heuristic Evaluations
Conducting Heuristic evaluations

Form a team of 3-5** specialists to perform individual inspections against list of
heuristics

** Studies show that use of 4-5 evaluators result in 80% identification of accessibility problems.
More is better!

Evaluators require guidelines, standards, usability guidelines, and UI design experience

Comparative analysis of collected data, formulate report
Implement formal inspection process

Appoint moderator to manage the team

Plan the inspection, conduct kick-off meeting, develop preparation phase for individual reviews,
conduct main inspection, end with follow-up phase to assess effectiveness of the inspection

Plan user testing

Usability Testing
Basis

Automated testing rarely results in capturing true user experience

Heuristic evaluations cannot address all usability issues

Not able to fully emulate user experience (unless inspector has a disability)

Task analysis is generally not part of the heuristic evaluation
Benefits

No preconceived notions, expectations, or application prejudices

Validates user requirements

Confirms heuristic evaluations

Builds client confidence.

Assures AUE (accessible user experience)

Conducting User Testing
Setup

Establish an accessibility center to perform user testing (Hint: Collaborate with disability
organizations)

Recruit sample users and ensure:


Cross-disability sampling

Multi-AT configurations

Variable user experience level (novice, average, expert)
Involve client developers, engineers as observers
Reminders

User testing is *not* beta testing!

If permissible, video record sessions

Do not “lead” participants

Perform iterative studies

Pay participants and thank them!

Summary and Conclusion
3 key words

Clarity – Process/Plan/Standards

Compatibility

Usability
To achieve greater web access we need to focus on
1.
Clarity of standards, guidelines (via standards initiatives)
2.
Compatibility with assistive/adaptive technologies
3.
Infuse usability methods that engage individuals with disabilities into mainstream product design
Goal is “overall” accessibility of the whole technology system – you are encouraged go
beyond what is minimally required.
Section 508 is about accessibility, and accessibility is about business opportunity – Go for it!
