About captivate-generated video and accessibility
Captivate can be used to create animations or videos as FLASH files, from screen capture or by animating Powerpoint slides. It does a lot of the behind-the-scenes enhancements of FLASH. People making videos with Captivate should follow the guidelines for
Use the latest possible version of Captivate, as this will have more options for creating accessible videos. When starting the Captivate project, select 'enable accessibility'. Doing this adds functionality to increase accessibility. Follow the best practices for Captivate from Adobe.
Accessibility applies to more than just the Captivate end product
If you are making an instructional video, you should include accessible techniques. For example, if you are making a video showing people how to print out a file, show options for clicking the print icon for people who can see the icon, but also show the option of selecting File and then Print for people who may be using a screen reader.
The following guidelines are specific to Captivate, some sourced from the SSB Bart Group.
Making the purpose of your Captivate file clear
Describing the FLASH file
Fill in the Project name and Description. This will be read out by a screen reader when the FLASH file is in the page so the person will know what the file is about.
Slide Accessibility Text
Each slide can contain more text. This can be added by going to the slide properties, activating the Accessibility button and entering text in the text field. Don't repeat the text in the slide, or this will only double the content read out unnecessarily. Add more text if it will add more information. Certainly explain any graphics or images.
Closed Captioning for video with audio
Closed captioning can be added to all audio files. From the record audio dialog, closed caption text can be added under the Caption tab. The playback bar contains a CC button which allows the closed captioning to be displayed or hidden.
Operating Captivate in a webpage
Text buttons can be made accessible. The text that appears on-screen becomes the button's accessible name. To make the buttons keyboard accessible, the "Set Keystroke: Select Keys" button should be used and the keystroke of "enter" should be set in the object's properties dialog. Other shortcuts can be assigned but enter/space will then not work to activate the button after tabbing to it. The keystroke of "enter" can be assigned to multiple buttons and the button with focus will be activated when Enter is pressed.
Shortcut keystrokes can be assigned to click boxes and buttons. Use the "set keystroke: Select Keys" button to set the shortcut keystroke. Audio recordings can be associated with click boxes and thus authors can associate descriptive text to be announced when a shortcut keystroke is pressed to assist users with visual impairments.
