Title: Reallife AT Examples: Part I


1
Real-life AT Examples  Part I
  • Eric Damery
  • VP Product Management
  • Glen Gordon
  • Chief Technical Officer
  • Freedom Scientific, Inc

2
Blindness AT industry
  • Worldwide revenue of 150 million per year
  • Screen readers, braille displays, scanning and
    reading, and embossers
  • Small companies with specialized expertise
    focused on assistive technology for those that
    are blind
  • Freedom Scientific is the largest player
  • Has 38 blind or low vision employees
  • Most other companies are smaller and have less
    than 30 employees

Techniques Used by AT
  • Take advantage of all available information to
    create flexible and powerful products for our
    users
  • Accessibility APIs such as MSAA, Java Access
    Bridge, IAccessible2, and UI Automation
  • Application APIs not specifically designed for AT
    such as the Microsoft Word Document Object Model
  • System level APIs
  • Once we get the information, our real work begins
  • Reorganize the information to maximize
    productivity
  • Develop a user interface that is based on
    keyboard input with speech and braille output

APIs are Only a Starting Point
  • An API is only as good as the understanding the
    person has who implements it for a particular
    application
  • Application developers do not always understand
    what AT needs and why
  • Difficult or impossible for them to test without
    special training
  • Freedom Scientific worked with IBM on
    IAccessible2 API
  • Result IBM products that support the API are
    accessible with JAWS
  • Microsoft considered AT early in the development
    process of Vista
  • Result Freedom Scientific and other AT products
    support Microsoft Vista at launch
