  1. The Ramp to Accessible Software -- Designing, Developing, and Testing for Online Accessibility Presenters: Mike Paciello, TPG & Larry Goldberg, NCAM Consulting – Services – Technology – Training

  2. 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.

  3. 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”

  4. Introduction • The Story of Brian… • Challenge for IT Vendors and Service Consultants • Determine the accessibility state of Web & software user interfaces • Delivery of quantified recommendations that result in User Interface Enhancements (UIE) for people with disabilities • Incorporating accessibility into product development lifecycle • Concept & design • Development & product management • Documentation, Training, & Help systems • Q/A & Usability testing • Marketing and sales • 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

  5. 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

  6. Understanding Section 508 • Federal agencies who develop, procure, maintain, or use electronic and information technology must ensure that it is accessible to people with disabilities including: • Federal employees • Members of the public who have access to and use Federal E&IT • Section 508 Technical Standards • Subpart B -- Technical Standards • 1194.21 Software applications and operating systems. • 1194.22 Web-based intranet and internet information and applications. 16 rules. • 1194.23 Telecommunications products. • 1194.24 Video and multimedia products. • 1194.25 Self contained, closed products. • 1194.26 Desktop and portable computers. • Subpart C -- Functional Performance Criteria • 1194.31 Functional performance criteria. • Subpart D -- Information, Documentation, and Support • 1194.41 Information, documentation, and support.

  7. Why Commit to Section 508? • Commitment to Section 508 and accessibility of information technologies to people with disabilities involves embracing accessibility and building Section 508 requirements into your products and services. • The subsequent ROI - • Broadens your opportunity to reach an untapped market opportunity of approximately 54 million • Reduces the liability associated with legal repercussions • Enhances your corporate image

  8. Engineering Approach and Methodology Kickoff Initial Assessment Technology Audit Remediation, Consultation, & Implement plan • Review project objectives and scope • Develop action plan • Review of policies, standards, and architecture • Review of insights on regulatory environment • Detailed analysis of IT and software • Automated & manual testing • Evaluation measurable cost options • Leverage company investment, development planning • Enhance architecture and design plan Q/A & Usability Testing Independent Validation Monitoring Market Solutions • Develop Q/A and Usability test plans supporting accessibility • Contract with outside expert • Establish regular intervals of IT review, audit • Create client reliability factor – you’re in this for the long haul. • Press, awareness training, brand marketing for accessibility

  9. 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

  10. Checklist for Developing an Information Architecture • Review requirements and task analysis • Evaluate your content • Develop a organizational development structure based on content, tasks, user personas, features and market demand (test the structure via user testing, walkthroughs) • Map your tasks and procedures to your site/application organizational structure • Build a navigational schema • Implement the architecture and test against design specification

  11. 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)

  12. 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

  13. 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)

  14. 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

  15. Simple & natural dialogue Familiarity (speak the user’s language) Minimize the user’s memory load Consistency Feedback Clearly marked exits Shortcuts Good error messages Prevent errors Help & Documentation Accessibility UI Heuristics

  16. 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)

  17. 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!

  18. Software Applications & Operating Systems: Minimal Standards for Functional Performance • Section 508 Requires • At least one mode of operation and information retrieval shall be provided as follows: • Does not require user vision OR includes support for assistive technology for people with visual disabilities • Does not require user hearing OR includes support for assistive technology for people who are deaf or hard of hearing • If audio information is important, enhanced auditory support OR assistive hearing devices shall be provided. At least one mode of operation or information retrieval that: • does not require user speech OR provide appropriate assistive technology • does not require fine motor control or simultaneous actions and is operable with limited reach and strength

  19. Keyboard Accessibility • For systems that include keyboards, product functions must be executable from the keyboard. • Function itself or result of the function must be discerned textually • Applications cannot disrupt or disable documented accessibility features including: • Features made available through the operating system • Features made available through other products • Windows, Mac’s and Unix (Linux too) support accessibility keyboard functions including: • Mouse keys: Control pointer with numeric keypad • Bounce keys: Control rate of “taps” on keys • Serial keys: Allow serial devices access to keyboard and mouse functions • Sticky keys: Press 1 key for multiple key functions • Toggle keys: Emits tones for Caps, Num, and Scroll Locks • For additional information, Select Control Panel – Accessibility Options

  20. User Interface • Ensure that user focus is available through on screen indicators • Ensure that user focus is exposed to assistive technology that tracks user focus and focus changes • Expose sufficient information about user interface including identity, operation, and state of elements to assistive technology • Provide textual information through operating system functions for displaying text. • Minimal requirements shall include: • Text content • Text input caret location • Text attributes • Applications should not override selected contrast and/or color settings • Do not use color coding as the only means for conveying vital system or application information • Do not user blinking or flashing text, objects, or other elements that flash or blink at frequency rates greater than 2 Hz or lower than 55 Hz • Animated information shall be available in at least one non-animated form that is optional to the user

  21. Images and Graphics • If the element is an image or graphic, the image information should be conveyed through text • Assign consistent meaning to bitmap images used to identify controls, status indicators, or other programmatic elements.

  22. Forms • Ensure that forms are fully accessible to people using assistive technology • Users should be able to access all form: • Information • Field elements • Functionality for completion • Including directions and cues

  23. Manual Tests • Unplug the mouse and make sure keyboard access is provided to all active objects such as buttons and scroll boxes. • Make sure tab elements such as links, tool bars, and form fields are loaded out in logical order. • Provide meaningful names in the application for all text and graphics based elements • ** Information taken from Sun’s Guidelines for Software Accessibility.

  24. Product Support Documentation & Customer Service • Section 508 includes provisions to ensure that users with disabilities have access to associated product support features, including the following minimal standards: • Documentation available in alternative formats (ex: braille, large type print, audio) • At no additional charge • Product feature information available in alternative formats • Including accessibility features and compatibility information Customer service support shall accommodate communication needs of end-users with disabilities • For example: • TTY/TDD services for the deaf and hard of hearing
