accessibility tips and tricks captivate elearning general content creation

  • Captivate has a number of accessibility features in version 3 and 4 although there are some issues that Adobe is working on.
  • Ensure that the “enable accessibility” checkbox is checked under the File > Publish settings in order for accessibility to be exposed to assistive technologies.
  • Slide Accessibility Text Each slide can contain accessibility text. This can be added by going to the slide properties, activating the Accessibility button and entering text in the text field.

  • Closed Captioning 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.
  • Button Accessibility 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.
  • 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.
  • Text from PowerPoint Much of the text from PowerPoint will come through as text in Microsoft Active Accessibility (MSAA) and will be exposed to users of screen readers. Currently there isn’t a method to change the order or edit this text.
  • Quiz Questions There is some accessibility support for quiz questions. Simple types of questions such as true and false and multiple choice provide accessible names for the radio buttons and the text of the question appears as text in the accessible MSAA structure and is exposed to screen readers.
  • Accessibility Differences Between Captivate 3 and 4 The text in the “text caption” object does not show up as accessible text in Captivate 3 but does in Captivate 4. In addition, it is not possible to set accessible text for specific images in Captivate 3 but it is possible in Captivate 4.

DIG252 keyboard accessibility navigation focus html

  • tabindex="0" and tabindex="-1" have special meaning and provide distinct functionality in HTML. A value of 0 indicates that the element should be placed in the default navigation order. This allows elements that are not natively focusable (such as <div>, <span>, and <p>) to receive keyboard focus. Of course one should generally use links and form controls for all interactive elements, but this does allow other elements to be focusable and trigger interaction.
  • A value of 0 indicates that the element should be placed in the default navigation order. This allows elements that are not natively focusable (such as <div>, <span>, and <p>) to receive keyboard focus.
  • A tabindex="-1" value removes the element from the default navigation flow (i.e., a user cannot tab to it), but it allows it to receive programmatic focus, meaning focus can be set to it from a link or with scripting. This can be very useful for elements that should not be tabbed to, but that may need to have focus set to them. A good example is a modal dialog window - when opened, focus should be set to the dialog so a screen reader will begin reading and the keyboard will begin navigating within the dialog. Because the dialog (probably just a <div> element) is not focusable by default, assigning it tabindex="-1" allows focus to be set to it with scripting when it is presented.

  • A value of -1 can also be useful in complex widgets and menus that utilize arrow keys or other shortcut keys to ensure that only one element within the widget is navigable with the tab key, but still allow focus to be set on other components within the widget.
