Values

This property is typically only set when a publication contains scripted content that requires user interaction (i.e., whether the author has ensured that such content can be controlled by the various input methods). It is not a useful indicator for static content, and is not a guarantee that any user agent is accessible with such controls.

The following values are recommended for this property:

fullKeyboardControl

The fullKeyboardControl value is used to indicate that the content can be controlled using only a keyboard (e.g., for users who require adaptive keyboards).

fullMouseControl

The fullMouseControl value is used to indicate that the content can be controlled using only a mouse (e.g., for users who require a trackball mouse).

fullSwitchControl

The fullSwitchControl value is used to indicate that the content can be controlled using only a switch device (e.g., sip and puff, foot switch).

fullTouchControl

The fullTouchControl value is used to indicate that the content can be controlled using only touch devices (e.g., for users who require a mouth stick or head wand).

fullVideoControl

The fullVideoControl value is used to indicate that the content can be controlled using video recognition devices (e.g., eye tracking).

fullVoiceControl

The fullVoiceControl value is used to indicate that the content can be controlled using only speech recognition software (e.g., Dragon).
