Purpose
  • Improve Java application accessibility
    awareness

4
Definitions
  • Disability -- Functional limitation in vision,
    hearing, movement, manipulation (for example,
    fine movements to use mouse), speech, and
    interpretation of information (for example,
    dyslexia and other cognitive impairments)
  • Accessibility Providing persons with
    disabilities comparable access to and use of
    information and data as persons without
    disabilities

5
Section 508
  • Section 508 of the Rehabilitation Act
    amendments of 1998 (http//www.section508.gov/inde
    x.cfm?FuseActionContentID12Web)
  • For Federal purchases of information technology
  • Requires Federal employees and members of the
    public with disabilities have access to and use
    of information and data comparable to that of
    employees and members of the public without
    disabilities
  • Is spreading beyond Federal government
    (http//www.gcn.com/vol1_no1/daily-updates/26304-1
    .html)

6
Screen Readers
  • http//www.doit.wisc.edu/accessibility/video/intro
    _scrn_rdrs.mov

7
Some Accessibility Requirements
  • Provide keyboard-only access to all functions
    (example)
  • Provide keyboard mnemonics (ex. ALT-F for File
    menu) for menu bar menus, frequently-used
    components, and all dialog window components
  • Duplicate toolbar buttons in menu or provide
    keyboard access to toolbar
  • Use Swing keyboard bindings (ex. F6 to move
    between panes) (http//java.sun.com/j2se/1.4.2/doc
    s/api/javax/swing/doc-files/Key-Index.html)
  • Provide functional keyboard equivalents for mouse
    functions

8
Example for Provide keyboard-only access to all
functions
9
Some Java Accessibility Requirements (Continued)
  • Dont interfere with accessibility features
    (ex. inverse video, sticky keys)
  • Show focus visually and programmatically
    (example)
  • Make all user interface elements (ex. icons)
    available via text
  • Use operating system to display textual info
    (ex. text, text input carat, text attributes)
  • Do not override user-selected color, contrast,
    font size, keyboard repeat rate, etc. (example)
  • Allow users to turn off animated info, but
    still get the info
  • Dont use color as only way to convey
    information (example)
  • Dont blink between 2 Hz and 55 Hz
  • Make forms accessible (ex. place prompt left of
    entry field)

10
Example for Show focus visually and
programmatically
11
Example for Do not override user-selected color,
contrast, font size, etc.
12
Example of Dont use color as only way to convey
information
  • Before
  • After

13
Some Accessibility Suggestions
  • Provide high contrast for text (example)
  • Use tab order that makes sense to users
    (example)
  • Dont use unnecessary graphics (example)
  • Provide default focus on every window
  • Set a component to execute the java.awt.Componentr
    equestFocus method
  • Describe icons and other functional graphics
  • Call the setIcon( ) method
  • Use the setDescription( ) class
  • Label all components
  • Implement the AccessibleName method on all
    objects
  • Implement the AccessibleDescription Method
  • Allow users to see visual version of audio
    alert
  • Enable Windows sound accessibility flashed title
    bar, window, or desktop can also flash status
    indicator on taskbar, etc,
  • Dont use timed responses if you must, allow
    users to extend the time

14
Example for Provide high contrast for text
  • Before
  • After

Date (mm/dd/yyyy)
Date (mm/dd/yyyy)
15
Example for Use tab order that makes sense to
users

17
For Best Results Use
  • Java 2
  • Java Foundation Classes Swing User Interface
    Components
  • Java Accessibility Application Program
    Interface
  • Java Access Bridge for Windows 1.1
    (http//java.sun.com/products/accessbridge/)
  • Dont use applets (some assistive technology
    browsers dont support them) use Sun Web Start

18
Java Access Bridge
  • Communicates between assistive technology (ex.
    JAWS) and native code of Java Access Bridge
  • Bridge for Java Accessibility API between Java
    virtual machine and Windows
  • Uses two Windows Dynamic Link Libraries and one
    Java language classfile
  • Note Users need Java Access Bridge on their
    machines.

19
Testing
  • Use Java Accessibility Helper
    (http//java.sun.com/developer/earlyAccess/jaccess
    helper/)
  • Use application with only keyboard
    (http//java.sun.com/j2se/1.4.2/docs/api/javax/swi
    ng/doc-files/Key-Index.html)
  • Use JAWS screen reader (http//www.freedomscient
    ific.com/fs_products/software_jaws.asp)
  • Print screens on black white printer
  • Use BMC accessibility checklist
    (http//cww/internal/ResearchAndDevelopment/Usabil
    ity/attachments/SmartNumber_section508_assessment.
    doc)
  • Use IBM Java accessibility checklist
    (http//www-306.ibm.com/able/guidelines/java/acces
    sjava.html)

20
Accessibility at BMC
  • Accessibility program lead named (Chris Meier)
  • Accessibility consultant hired (The Paciello
    Group)
  • Reviewed SmartDBA and Metropolis
  • Delivered 20-minute-long Webinars
  • Will provide half-day Java accessibility
    training
  • Accessibility awareness program begun (CWW, Brown
    Bags)
  • Accessibility section added to BMC RD Usability
    portal (example)
  • Over 500 products evaluated using BMC Section 508
    Product Assessment Form
  • Completed accessibility form now required for
    products release to market process
  • Federal agencies now requiring information on
    when BMC products will conform to Section 508
