Keyboard Triggers

    Description

    Configure any action – turn page, play video, maximize image, etc. - to be triggered when a predefined key or keyboard shortcut is detected. Combined with text-to-speech and a Braille keyboard, touch experiences become accessible for the physically and visually impaired.

    This feature even makes it possible to use a clicker to remotely navigate through your experience as most clickers simply simulate keyboard presses (left/right arrow keys).

    In Composer, in the menu option Project -> Project Settings, you can activate/deactivate the Navigate using arrow keys property.

    When activated,

    • the right and down arrow keys will call the Next action.
    • the left and up arrow keys will call the Previous action.

    If any of these key presses (e.g. left arrow key pressed) is redefined in scene (see below), the associated navigation action will be overridden thus not called.

    Generic key trigger

    The Keyboard key(s) pressed trigger enables IntuiFace to detect any key or keyboard shortcut. When selecting this trigger, press the key or combination of keys before selecting the action(s) you will call.

    A keyboard shortcut is two or more keys pressed at the same time. One of those keys is either Shift, Ctrl, or Alt.
