Chapter 21: Making Director Movies
Accessible
®
®
Adobe
Director
includes features that let you make existing and new movies accessible to users who have hearing,
visual, or mobility impairment.
The U.S. government has stated that multimedia created for the purpose of fulfilling a government contract must be
made accessible to computer users with disabilities. The government requirements include text-to-speech,
captioning, and keyboard navigation features. The full text of the government requirements is available at
www.section508.gov/.
You make your Director movies accessible by using behaviors or writing custom scripts. Director includes several
behaviors that let you easily add text-to-speech, captioning, and keyboard navigation to your movies with simple
drag-and-drop procedures. To have more control over accessibility implementation, you can write custom scripts
that use the text-to-speech methods. For more information about text-to-speech script, see
with Lingo or JavaScript
syntax.
After implementing the accessibility features, you must deploy the movies in a way that ensures that the features will
work for users. For deployment information, see
Using the Accessibility Behavior library
The Director Library palette includes an Accessibility section that contains behaviors for enabling keyboard
navigation, text-to-speech, and captioning.
•
For keyboard navigation, use the Accessibility Target, Accessibility Item or Accessibility Text Edit Item, Accessi-
bility Keyboard Controller, and Accessibility Group Order behaviors.
•
For text-to-speech, use the Keyboard Navigation behaviors, and then add either the Accessibility Speak or Acces-
sibility Speak Member Text behavior. You can also use the Accessibility Speak Enable/Disable behavior to let users
turn the text-to-speech feature on and off.
•
For captioning, use the Keyboard Navigation behaviors and Accessibility Speak behaviors, and then add the
Accessibility Captioning and Accessibility Synch Caption behaviors.
Enabling keyboard navigation
With the Accessibility Behavior library, you can easily make sprites on the Stage navigable with the keyboard. This
lets users select sprites and simulate mouse clicks without using a mouse. For example, if you have four button sprites
on the Stage, you can attach accessibility behaviors that let them be selected by using the Tab key. As each sprite is
selected, it is highlighted with a colored rectangle, called a focus ring, around its bounding rectangle. After a sprite is
selected, the user can press Enter (Windows®) or Return (Mac®) to initiate the same action that a mouse click would
initiate on the sprite.
Most accessibility behaviors cannot be used alone and must be used with other accessibility behaviors. For example,
to enable keyboard navigation, you must use the Accessibility Target, Accessibility Item, Accessibility Text Edit Item,
Accessibility Group Order, and Accessibility Keyboard Controller behaviors together.
